Home Theater Plasma TV VS Projectors

Home Theater - Plasma TV VS Projectors
By Jakob Culver

Many homeowners are struggling with an important, electronic question: What is the ideal display for my home theater? Many people have fought this debate, but I'll try to make clear some important considerations.

The most important detail to consider when deciding between a projector and a large plasma television is ambient light. A room with lots of windows presents a problem for a projector because every little bit of ambient lighting degrades the projected image. The ideal environment for a projector is one where you have total control over the lighting. If your home theater uses a projector, you are limited to using it when you can eliminate other light. A plasma screen can be used anyplace, anytime.

Assuming your home theater has blackout curtains, or exists deep underground; let's examine differences between a plasma television and a projector. One advantage of a projector is that you can get a much larger picture than is available in plasma. Projectors can produce images comparable to an 81-inch screen and larger. This just isn't possible with a plasma screen. However, plasma's have the advantage of not needing any amount of space. A projector must have a long enough corridor to project its image on the wall or screen. To get an 81-inch or greater image, you need a decent distance between the projector and the target. Second, a projector's image is dependent on more than the quality of the projector; you must be projecting onto a specialized surface or you lose detail. A top of the line HD projector with a very high native resolution would be wasted if you were just projecting the image onto a wall. You need an equally high quality screen with features such as a matte finish to eliminate reflection and glare. A plasma display requires no additional equipment.

Overall, a projector has the potential of creating a beautiful image, but it needs too much to work effectively. If you're creating a private movie theater with lighting control and an investment in a screen, mounting equipment, and blackout curtains, then a projector is your piece of equipment. For everyone else, I suggest a plasma television.

Digital Projector Guide Some Tips for Digital Projectors

Digital Projector Guide- Some Tips for Digital Projectors
By Sardool Sikandar

Digital projectors are equipments of modern technology. These are used to convert image data directly from the computer onto a screen via lens system. Digital projectors provide visualization of data that is actually stored in a computer for presentation. These projectors enable the viewers to watch moving images from a DVD, digital versatile disc player. Advertisers or sellers also use these projectors to give demonstration of products to a large number of customers. It can easily convert written documents onto an interactive whiteboard.

Digital projectors play an important role in the formation of home theater systems. These projectors use resolution of SVGA standard i.e. 800600 pixels in expensive devices. Cost of digital projector is determined by its resolution as well as its brightness. If youre going to use it in large rooms or big conference halls its brightness should be from 1,000 to 4,000 ANSI lumens.

First digital projectors, Eidophor projectors were introduced in 1950. Eidopher projectors used an oily surface in a rotating disk with light shining through it and employed an electron beam to disrupt oil in a specific manner. Eidophor projectors were not able to produce colors. Nowadays there are several high quality models of digital projectors are available in market so Eidopher projectors are less common.

Following four technologies are used in digital projectors:

High intensity CRT
LCD projectors using LCD light gates
Texas Instruments' DLP technology
Eidophor oil-film projectors (obsolete)

At present LCD projectors use Texas Instruments DLP technology whereas the high intensity CRT devices are suitable for enduring installations. Entire working of cathode ray tube digital projectors is like CRT television set. These projectors may be configured with one RGB color tube that has three colors red, green and blue with a single lens, one black & white tube with a rotating color wheel or three RGB color tubes with three lenses. Projectors having cathode ray tubes are usually bulky thats why these are the best projectors for fixed installations.

LCD digital projectors are portable and lighter enough in comparison to CRT and can be easily shifted from one place to another. These are very much popular and available in various shapes and sizes. CRT and LCD digital projectors come under the category of transitive projectors.

Reflective projectors are the superior digital projectors that provide high quality images. These are affordable and offer next level of entertainment. Everyone can enjoy home theater applications with the help of digital projectors.

Digital LCD Projectors

Digital LCD Projectors
By Ken Marlborough

Digital projectors are the modern replacements for the rather traditional transparency projectors. Transparency projectors worked by shining light through a semi-transparent material. Digital projectors, by contrast, project a digital image directly from a computer through a lens on to a screen.

LCD (Liquid Crystal Display) digital projectors are much lighter and more portable than their CRT (Cathode Ray Tube) versions, making them widely popular. With the advent of new LCD technologies, digital projectors have been developed which have very clear and crisp fidelity even at large projection sizes. The LCDs used in digital projectors are approximately the size of a small color slide, and in fact the projectors operate very much like a traditional slide projector. The main difference is that the slide is constantly changing.

A Digital LCD projector has its light source contained within its base. It projects light upwards through the transparent image (which sits on a glass stage) to a lens on the top (head) of the unit and out onto the projection screen. In other words, the light shines through the image to project it. These projectors work well with printed film transparencies or an LCD panel computer display and provide bright, sharp images.

Slightly higher end Digital LCD Projectors can be used for Cinema/exhibition, Post-production, On-screen advertising, Digital film mastering, Multi-media theatrical productions or other large entertainment venues. Most of the recent Digital LCD projectors can be installed with existing film projectors and also provide an interface for theatre automation equipment.

The future of digital projectors is exciting, with new technologies constantly being developed. As more and more theatres switch to digital projection, consumers cannot help but reap the benefits. As these technologies become more affordable they will inevitably find their way into home systems and allow each of us to experience the joy of a full theatre projection in our own home.

How To Choose A Projector

How To Choose A Projector
By Jakob Culver

Good presentations make the foundation of the successful business deals. So while making presentations make sure that you have an easy access to a good projector which suits your requirement as this is going to at as a catalyst for a business deal to happen! The picking of projectors is mainly dependent on the type of work or the kind of business that you have. As for an advertising firm presentations are very frequent so they make doubly sure that they procure a good projector!

The other factor that determines the selection of a projector is the dimension of the room or the conference hall where the presentation is scheduled. As the clarity and readability of the data projected varies from the projector which is designed to function in small room as compared to large room , so presentations for larger areas and for a great number of people should be made through more sophisticated projectors.

Portability of the projector is the another issue, if you usually travel from one place to another for their business presentations then make sure that you invest in a good quality portable projector that is easily transported and provides an easy set up. It is mandatory that it can be set up instantly as who would be carrying a throng of technical people when doing mobile presentations. A projector that easily connects with a personal or portable computer will be ideal to make your presentations simple but sophisticated.

Norms suggest that a portable projector with a minimum brightness capacity of at least 800 lumens is fine to handle the presentations. In contrast to this larger projectors must have a brightness capacity of at least two thousand lumens to make the presentation clear even to those who are seated at the back of the room. A projector must have at least a minimum of 1500 lumens to be able to project effectively in a room where plenty of light comes in as when there are no blinds or curtains

Once you have decided on the type of the projector that you will be using, then make sure that you use projectors in a dark room but if it cannot be avoided, always position the projector at an area where there is less light. It is also important to take note of the resolution of your projector as this signifies the amount of pixels it can display. . Projectors can be easily installed but it is best to consult technical people for setting up the projector especially if they will be mounted to the ceiling. Make sure your projector's efficiency will last long by using alcohol or a special cleaning solution for the projector lens.

So go ahead and make a appropriate selection from a wide variety of projectors that are available in the market and just to tell you that vendor will be one happy person to give a trial presentation, so make sure that you dont miss on that as it will throw more light on the projector features.

Consumer Electronic Information: The Basics of the DLP Projector

Consumer Electronic Information: The Basics of the DLP Projector
By Simon Canfield

Projectors have come a long way in the past few decades. The desktop fossils that were once used to show home moviesor classroom filmstrips are a thing of the past. With todays technology, you can now experience a projected movie that emulates a full-blown theater flick, without thetime, effort and hassle of standing in line at the local cinema.

DLP projectors also known as Digital Light Processing projectors have brought the proverbial silver screen to the home front. The fact that some theaters actually use this type of technology for feature movie projection makes this truer than you might imagine. After being digitally converted and placed on an optical disk much in the same way as DVD technology is produced the images are fed intothe projector and sent to the movie screen. The main difference is that DLP projectors offer a high definition experience, as opposed to that of a DVD. The result is a picture that very nearly rivals the quality of a 70mm projection, but without the imperfections.

The color accuracy of the DLP system is outstanding, with an end result that beats LCD technology. Some of the advantages that make a DLP the projector of choice are its low power consumption, compactness, micro-mirror construction (which is responsible for the high level screen resolution), high contrast and brightness. All in all, this is the closest that anyone can come to having a bona fide cinema within the confines of their home.

With every set of pros, youll always find some cons lurking in the shadows. Such is the case with the DLP projector. For those who are particularly sensitive to certain visual effects, the DLP design produces a type of rainbow effect, which could serve as a distraction when looking from one side of the screen to the other during viewing. This will play out as a brief splash of colors, which is simply a result of the type of technology thats used in the production of the DLP. Most people dont even notice this color display, but those who are in tune to that sort of thing may see it as an annoyance.

While this is also true for LCD projectors, consumers mightbe disappointed to know that DLP projectors need to have their light source changed after every 1,000 to 2,000 viewing hours. All in all, though, this is nothing new and, when you consider the higher quality that this type ofsystem offers, it shouldnt be seen as much of an inconvenience at all.

Perhaps the most inhibitive aspect to the acquisition of a home theater system, such as the DLP, is that the cost willtypically fall within the range of $5,000 to $10,000 for the mid-range systems, once you purchase everything that youll need in order to complete the set-up. In addition to that, youll have to consider the cost of the rest of your home theater system, since these figures only factor in the DLP expenses.

For those who can afford to do so, the DLP projector is an excellent investment, despite its few downfalls. While no projection system is perfect, DLP is currently the most popular set-up on the market and provides a powerful theater experience for those who arent inhibited by space or finances.

Home Theater Video Projectors

Home Theater Video Projectors
By Jason Gluckman

A home theater enables us to view films in the comfortable ambience of our homes. The unique ambience of movie halls can be recreated completely, minus the crowds, and favorite movies can be watched with friends and relatives in comfort. Home theater video projectors are the main component around which the home theater system runs.

At present, there are three kinds of video projector technology in use. They are CRT, LCD, and DLP. Apart from these, there are certain modifications also available based on the technology used for the above three.

During the early years of video projectors, television expertise was centered on Cathode Ray Tube technology, or CRT. Cathode ray tubes are used for the generation of a television image. Three small CRTs with a single unit meant for every principal color, and a light-magnifying lens, helps in the projection of a color representation against a big screen in a dimly lit room. A CRT projector is capable of creating superior high-resolution images. This can be achieved with the help of the right combination of video processing circuitry, CRT size, and lens combination.

The second sort of video projector is the LCD projector, or Liquid Crystal Display. This is different from a CRT projector in the sense that it is not based on the conventional projection tube. An LCD projector primarily operates by delivering a strong light source through a transparent LCD chip comprising of individual pixels, which exhibits the moving video image. This image is subsequently projected through a lens to a big screen.

The rapid developing sort of video projector with respect to sales is the DLP, or Digital Light Processing projector. This type of projector is very similar to the LCD as in this also the real image is exhibited on a chip.

Computer Projector Rentals: A Guide

Computer Projector Rentals: A Guide
By Marcus Peterson

Any meeting or conference requires a computer to handle inputs like data, graphics, video and audio. Computer as a multimedia application has properties comparable to standalone players for VCD or DVD. With the integration of IT and the Internet into the audio visual industry, computers have become an indispensable item of equipment. They are a common product line in the inventory of a/v rental companies.

To have a meeting with computer aided presentation of data, graphics and video, one needs to have a projector that is compatible with different makes of computers such as IBM and Mac. For instance, an iMAC computer has different requirements than other systems. The accessories that come with computer projectors are audio and video cables, speakers and screen.

The type of screen is decided by the number of members in the audience. If it is a small gathering, a 27 monitor may be used. For large gatherings, a flat screen display or a plasma monitor with 50 monitor may be used. If it is a notebook computer, the laptop must be activated to have the output to the projector. Depending on the number of the people, importance of brightness, contrast and resolution, an LCD projector would be a good fit for the occasion.

The important factors an event manager must consider before choosing the a/v system are the room size, lighting conditions, the inputs that will be displayed, the resolution and clarity of the visual images and screen size. Depending upon the requirements, the rental rate may vary from $300 to $500. Also, the rental companies provide value added services such as complete solutions to manage the event.

Computer projectors are used by corporate houses and universities for business presentations and seminars. They can be booked by phone or online. Most rental companies deliver the systems the previous day. The major manufacturers of computer projector systems are Hitachi, 3M, Compaq and Canon.

How to Fix a Broken Slide Projector

How to Fix a Broken Slide Projector
By Jeffrey Saunders

A slide projector is a great way to store, share and show photos, presentations and other information. But what do you do when your slide projector is having problems. How to fix it can be a simple matter of jiggling a few wires, cords or cables, or taking the entire projector apart and taking a peek as to whats inside.

The most common problem with a slide projector that needs fixing is a simple projector jam. A projector jam is when one of the slides is stuck in a position that wont allow the carousel to rotate. Now, this may seem like a minor inconvenience, but it should also be the first area you look into when your projector is having problems. How to fix it, and remove the jammed slide can be done in a matter of steps.

1. Shut the slide projector off and let it cool down for a few minutes.

2. Remove the slide tray by loosening a latch or placing a coin in the middle of the tray & turning it

3. Turn the tray upside down

4. Locate the jammed slide and carefully remove it

5. Place the tray back into the projector

6. If the slide isnt damaged, insert it back into the carousel

The next time you notice your slide projector is having problems, how to fix it is to follow the steps listed above. Normally, when a slide projector wont fully rotate, its because of a jammed or lodged slide within the carousel. Carefully removing the trapped slide should solve any projector problems youre experiencing.

If youve followed the steps noted above, and you find that still your slide projector is having problems, an experienced technician may tell you how to fix it, and guide you through various stages of repair. The larger the slide projector you have, the more chances it has to jam. So before you take your projector apart or visit a potentially expensive repairman, be absolutely certain that it isnt a jammed slide thats causing your projector problems.

If your digital image projector is having problems, how to fix it can be a matter of replacing a burnt out bulb, ensuring that all your cables are properly connected to rebooting the entire system itself, depending on the sophistication level of your projector. Always go through the instruction manual when your digital projector is acting up.

Sometimes when your projector is having problems, how to fix it can be as easy as remounting it or reinstalling it. An improperly mounted projector can sometimes not project any image at all, and may appear to be broken and in need of fixing. Check to see if your projector is mounted and affixed straight. If it isnt, take it down and remount it, being careful to make certain that its properly mounted. That should solve any issues regarding your projectors refusal to show images. If that does not work, then you may consider taking your digital projector back to its point of purchase for a qualified inspection.

Jeffrey Saunders loves do-it-yourself technology

He also likes great deals on refurbished electronics. Amazing prices on big brand names like the Apple iPod Nano

And more fantastic deals on great items like digital camcorders.

Video Projector Guide

Video Projector Guide
By Riad Haddad

Well; the world of Projection is certainly a vast place to wonder uninformed, so get informed. I will try to keep this guide as simple as possible.

Things to look for when buying a projector:Manufacturer/MakeThere are many projector manufacturers these days that make it seem impossible to choose from. But to make it simpler, many manufacturers now a days use parts that are supplied from other manufacturer. In other word not all the parts in a projector is manufactured by the same manufacturer. Thus many projectors already have similar components incorporated into them. Always read reviews posted on computer magazines and online computer magazines before purchasing high end/high priced projector. Look for a company that offers the best warranty & support. Brands like Sony, Panasonic, Toshiba, Sharp, In-focus, View sonic, Mitsubishi, Epson are amongst the best there is.

TechnologyThere are many technologies available today. But the main two types are LCD & DLP. In simple DLP which stands for Digital Light Processing uses hair width tiny mirrors to reflect light into a screen. DLP offer better overall image but cost a lot more. So for home users its better to opt for LCD based projector because of there much lower price and higher availability. Also LCD projector offer excellent image that is comparable to DLP. Big companies and presentation oriented businesses well find DLP a better choice. There are also projections panels. Projections panels are a form of transparent display that are placed over an ordinary Overhead projector and used to project the same type of video sources that normal projector use. Projection panels are cheaper than the types described earlier.CRT Projectors are an old projection technology that is no longer used these days.

ResolutionResolution is very important aspect to consider when purchasing a projector. Many older models are VGA (640*480) & SVGA (800*600); these models are good for displaying movies and other low resolution images, but will no be sufficient for projecting high quality images demanded by high end application such as 3d modeling, games, simulators and CAD. Check the simple chart below:

640*480 (VGA) resolutions are good for Video Games, VHS, VCD and Standalone DVD users. This panel is perfect for DIYers wanting to keep costs at lowest.800*600 (SVGA) resolutions are perfect for Computer based DVD playback and normal Windows and operation system work. (Plus all the above)1024*768 (XGA) resolution is perfect for high resolution Computer Games and design applications such as AutoCAD (plus all the above)1280*1024 (SXGA) resolution is perfect for HDTV applications and computer software that require high detail (plus all the above)

Color DepthColor depth states how good the LCD represents color. Its the number of colors a monitor or an LCD panel is able to show. A good color depth is 16-Bit; although 24-Bit is strongly advised, this is the color depth that most high end projection panels have.

Lamps An important thing to investigate is the type of lamp used. Check the replacement price of lamps and life expectancy. It would make you no good if you purchase a low price projector and later find out that every lamp replacement will cost you 400$. New lamp models can work for a minimum of 10,000 hrs.

BrightnessBrightness output is expressed in lumens. The higher the lumens the better the image is displayed in less than perfect lighting conditions. Some new projector models can display a vivid image even with the light on. 2000 lumens is a good choice for home use. Choose 3000-4000 for presentation theaters and jobs that require a bright image in a not too darkened room. Lumens rating of below 2000 such as the low priced 1300 models will have to be operated in a completely darkened room (Pitch Black).

ConnectionsConnections are a very important factor when choosing a projector. Composite, S-Video and RGB is almost standard on most models. You will need RGB for hooking your computer or laptop; Composite & S-Video for connecting DVD players and VCRs. Some newer models have DVI inputs too that enable them to be connected to high quality video systems like a video editor or digital video cameras. A remote control is a must; you don't wan to get out of your comfy chair every five minutes. Some applications require two RGB connections for simultaneous viewing of different video sources, so make sure to check for it if you need it.

Long throw/Short throw projectionIts important to decide where you are going to place the projector. If the projector is going to be placed in front of an audience then you will need a short throw projector. And if you need to fix the projector some where behind the audience (Far from screen) you will need a long throw projector. What happens when you use short throw projector for a behind the audience application is that the image will be too large to fit on screen, and if you use a long throw projector for short distances you will get a very small and unclear image.

DIY ProjectorsWell this is interesting. Did you know that you can build a projector yourself, its not that hard really and it will cost you a fraction of retail prices? You should have basic knowledge with DIY projects. The image quality is very good you won't believe it. Though some patience is required in order to complete the projector.

Compare LCD Projectors

Compare LCD Projectors
By Ken Marlborough

LCD (Liquid Crystal Display) projectors are devices used for displaying presentations or videos in an enlarged size. They are the modern replacements for slide projectors and overhead projects which were popular earlier.

LCD projectors are available in several variants with differing specifications. Choosing the right projector is as simple as knowing what it will be used for. The two parameters needed to compare an LCD projector are - cost and specifications. Knowing what is needed and how much you will need to use the various features / specifications of an LCD projector are going to be will help one compare the projectors with a better perspective. For this reason, it is important to know the basics of projectors before comparing them.

Aspect Ratio: It refers to the width vs. the height of the projected image. UXGA, VGA, XGA, and SVGA resolution all have a 4:3 aspect ratio.

Brightness: A projector's brightness is measured in lumens. The more light in the room where the projector will be used, the more bright the projector should be.

Contrast Ratio: Is the ratio between the darkest and brightest areas of the projected image. Medium Contrast ratio projectors can be found with a ratio of 500:1 to 1200:1.

Data Signal Ports: These ports on the projector should be compatible with whatever image source they will be paired with.

Keystone Correction: This is the ability to correct the image distortion that is created when a projector is placed at anything other than a 90 degree angle to the screen.

Native resolution: This resolution for a digital projector is the actual number of physical pixels on the projector's image chip.

Projection screens: These screens come in various fabrics and sizes. While it's possible to project the images on a blank wall, the best image quality will be achieved by projecting the images on a good screen.

Video Format Capability: A digital projector's video format capability determines which video format data it can accept. Most projectors will offer all three: PAL, NTSC, and SECAM.

A wide range of desired projectors can be found by giving exact specifications on various website over the internet. Once these basic features of projectors are compared and the best suited LCD projector identified, one can go ahead and compare the prices of the required projector.

Choosing a Digital Projector

Choosing a Digital Projector
By Luke Kent

There are tons of digital projectors available and they are constantly dropping in price. However, when choosing a projectorfor yourself or your school there are a few practical things you should remember.

When choosing a projector you need to consider under whatcircumstances will you be presenting slide shows. The strength ofa projector's brightness is measured in units called lumens. Projectors range between 650-5000 lumens. The higher the lumensthe brighter the projector. Projectors that are less than 1000 lumens may not be great in a room with a lot of ambient light.For a classroom you should consider buying a projector with greater than 1000 lumens. If the projector will be used forlarger presentations, for 100 or more people, a projector withgreater than 3000 lumens may be needed.

A great accessory to your projector is a wireless mouse. Thesehave dropped considerably in price and allow the educator toface their audience when presenting the slide show. Whenchoosing a wireless mouse choose one that has a long rangeso that you can walk around when presenting.

Many projectors also come with remotes that help the presentermake adjustments to the slide shows quickly during the presentationwithout having to fiddle with the projector.

Remember when buying a projector analyze you needs first. You maynot need to spend as much as you think or you may need to spendthe extra cash to get a projector that suits your needs.

Choosing A Conference Room Projector

Choosing A Conference Room Projector
By Jim Gelder

When it comes to choosing a conference room projector, you probably want to run and hide! Thats because most of us dont know much about projectors to begin with and dont know the first thing about how to select one thats appropriate for a conference roomor any room for that matter.

Thankfully, theres the Internet. Within minutes, you can have all the information on choosing a conference room projector that you could ever want.

Sorting through all that information, though, can seem overwhelming. So its good to have some questions in mind as you do the research necessary to find the perfect projector for your conference room.

Some questions you want to ask are:

How difficult is operating the projector?
Is the projector portable or will it need to have a permanent mounting? Which type fits my conference room needs best?
What types of presentations will the projector be used for?
How much does the projector cost?
Does that cost fit my for buying a new conference room projector?
Is there a service contract available for the projector?
What is the repair policy for the projector?
Is the company Im thinking of buying the projector from a reputable and reliable one?
Will the projector require any special maintenance or periodic service checks?
Are any special supplies needed for the projector?
Is the size appropriate for the conference room?
If its portable, how much does it weigh?
Should I rent, lease, or buy?
Is the quality of the brightness satisfactory for the size of my conference room?
Do I need to save the receipt so that I can take the purchase off on my taxes?

These are just a few questions to help you on your way to purchasing (or leasing) a conference room projector. Just remember that cost does not always indicate quality. You can buy a wildly expensive projector that is all wrong for your needs. The opposite is true too: you can get a great projector that fits your needs for a moderate, or even small, investment.

The trick is in researching projectors and taking the time to read some consumer reviews that are easily found on the web. Before you do anything, though, have a budget in mind and have some idea of what youll be using your projector for. This will help guide your research and make it go more quicklyand be much more effective to boot!

Digital Projector Give a Bigger Picture

Digital Projector -- Give a Bigger Picture
By NamSing Then

Digital projectors are those video projectors which are used in conferences for presentations. The digital projectors receive video signals from, usually, desktop computers and display images on large screens which can be easily comprehended by all in the gathering.

Two Types of Digital ProjectorsTo begin with, there are two technologies used by digital projectors, the older one being the LCD, liquid crystal display with independent transparent panels of LCD for each constituent primary color (red, blue and green.) The image transmission depends on the signal received by the projector from PC which redirects the light signals through these LCD panels and lens onto a screen. The LCD projectors look pretty similar to older slide projectors and are simple in construction and thus cost less in comparison to their successors DLP projectors. The LCD can be thought of as slides placed at the focal length of the lens making it complete. Clarity of picture in LCD projectors depends on the number of pixels it is set for. (Pixels are smallest area of data or picture holders)

DLP Projectors: The Latest of the Digital ProjectorsDigital Light Processing or DLP is a technology developed by Texas Instruments in 1987. DLP projectors bring in a paradigm difference in technology in image projection to board rooms. Unlike their predecessors, DLP projectors make use of tiny mirrors or micro mirrors to reflect light images to pass through the projector lens and onto a screen. Each mirror can be thought of as representing a pixel. The mirrors reflect primary colors in rapidly rotating succession as actuated by a rotating color filter wheel. The image of rapidly changing colors constructs images for human eye perception. The micro mirrors are collectively called as DMD or digital micromirror device.

For the sake of enhancing picture clarity, the rotating wheel is provided with a plain patch which allows plain white light. This type of DMD projectors are also known as single chip projectors. The three chip projectors are a bit complicated but offer better clarity. Here a prism splits the light from lamp into primary colors which are redirected to DMD which recombines them before projecting through the lens.

Where Is the DifferenceDLP projectors are lighter and give far better pictures. Single chip resolves 16.7 colors while the three chip model does a, hold your breath, 35 trillion colors.

Commercial ModelsTexas Instruments is the pioneer who owns the patent for DLP technology. Fraunhofer Institute of Dresden of Germany developed the same technology simultaneously and markets it as Spatial Light Modulators. HP, Samsung are other market leaders in both LCD and DLP technologies.

Video Projector Screens

Video Projector Screens
By Jennifer Bailey

A projector is an apparatus for presenting an enlarged image on a screen from a transparency such as a photographic slide or a film. In a motion picture projector, each frame is held stationary at an illuminated aperture for a brief period, and then advanced by an intermittent sprocket or reciprocating claw, the light being cut off by a rotating shutter during the movement. One should have a clear idea about video projectors before buying video projector screens.

Video projectors have become common and captured the market throughout the world. They are especially common in schools and colleges where it becomes necessary to show videos and films (especially in film schools and institutes), or any place where people need to show films on a regular basis at a cheap rate to a large number of people.

There is a wide range of video projector screens available in the market. One can buy the kind of video projector screen one wants depending on the kind of surface. The surfaces vary from smooth to rough, and minutely undulated ones. However, before considering any video projector screens, one should consider the following elements: resolution, brightness or reflectivity, contrast, color accuracy, and build quality.

Some of the white (or gray) video projection screens can bring about a difference in resolution, or image detail. There should be a rating to indicate its inherent reflectivity, on which the brightness of the image depends. Contrast of the image is also dependent to great extent on the video projection screen. A screen should not reflect any color other than that of the projector itself.

Ceiling Mount a Home Theater Front Projector Metalcraft Mounting System

Ceiling Mount a Home Theater Front Projector - Metalcraft Mounting System
By Kyle Kolbe

After I fainted from sticker shock at the pricing of the official Sanyo PLV-Z3 projector ceiling mount ($200), I found a much cheaper solution. For $36.95 I could buy a Metalcraft all metal adjustable ceiling mount off ebay.

Mounting a projector to my ceiling was easier than I thought. Heres how I did it.

Tools youll need:

* Philips Hand Screw Driver

* Circular Level

* EZ Anchor Stud Solvers

* Tape Measure

* Step Ladder

Size up the mounting hardware: The Metalcraft mounts ceiling plate is large measuring five by five inches square with six pre-drilled holes for ceiling screws. A post descends to the projector mount plate.

How I measured my room for optimum mount placement: Bisecting the width of the room, considering the airduct, and measuring eleven and a half feet from the front projector screens surface plus the half the length of the mounting plate, I placed the plate on the ceiling and marked each screw hole.

Anchored to ceiling: Wear safety goggles to avoid getting ceiling board dust in your eyes. I removed the plate and drove the metal EZ Anchor Stud Solver anchors until they were flush with the ceiling. The EZ Anchors are great because you never have to drill a pilot hole for the self-tapping anchors. I replaced the plate over the anchors and drove each #8 screw into its anchor. You may need an extra hand to hold the plate in place while you tighten the first two to four screws.

Attach the projector plate before attaching to ceiling plate: Since the mount assembly breaks into two parts, one attaching to the ceiling with a post that screws into the adjustment plate for the projector, you can screw and tighten the hex screws and plastic bushings to the projector body.

Secure the projector plate to the ceiling mount: The Metalcraft ceiling mounts post accepts a adjustable knob screw. You will need someone to help you get the screw started while they lift up the projector. With the screw tight you can rotate the projector from left to right on the ceiling post.

Fine-tuning: The Metalcraft mount allows yaw, pitch and rotation. With the hand tightening of knobs on the projector mount plate you can canter your projector perfectly on your projection screen. With the aid of a circular bubble level you can level the projector from front to back and left to right using the corresponding thumb knobs. With projector level you can then adjust your lense up and down and to the side for a perfect screen fill with no keystone distortion correction.

Caveat: The Metalcraft mount is wobbly because of the thinness of the metal used on the metal band that holds the projector mount to the ceiling mount post. When you need to change interconnects or adjust manual focus and zoom the projector rocks slightly as the metal gives. This does not cause the projector to fall out of register, though. Hey$36.95what do you expect?

The Metalcraft Mounting System for the Sanyo PLV-Z3 LCD projector (and many other projector brands and models) is a great bargain and very reliable. Highly recommended.

Father, Husband and Geek. My geeky interests have not changed since I was a kid. I still love comic books, anime, role-playing games, console video games, indie rock, imported toys and mecha models, bad American and great British sitcoms, and all the tech that lets me experience these hobbies to their fullest. Now that Im married with children, Ive had to strike a balance between supporting and pleasing my family and feeding my geekery hunger. Lucky for me, my wife is very accomodating and even geeks out with me on occasion (the ladies love Joss Whedons Firefly). My two year old likes anything that moves on the front projection screen and makes noise, so far she is easy to please. Geekwithfamily.com exists to enrich the lives of fellow geeks and the friends and family who put up with them.

Video Projectors

Video Projectors
By Elizabeth Morgan

Some of the various indispensable parts of a video projector are the feed spool, xenon arc lamp, projection lens, optical sound head, take up spool, an aperture, normal lens and a rotating shutter. But with the advancement of science, new technologies have come into play. The projectors have become much more advanced in terms of clarity of picture and the quality of the pixels. Also, the projectors have found use in everyday households, as new versions of domestic projectors have arrived on the market. The abundance of LCD projectors, DLP projectors and video projectors has allowed the common man to enjoy the experience of a big theater hall in his living room.

Video projectors have become very common throughout the world. One can have all the excitement and enjoyment of a big movie blockbuster at home. They are also used in schools and colleges where it is necessary to show videos and films on a regular basis to a large number of people.

It is always advisable to the users of video projectors or projection televisions to pay attention to the scaler. One can use a number of processors, scalers or switches to optimize the video sources to best match the native resolution of your video projector, flat panel, or LCD/DLP-based rear projection television. Video projectors have some kind of capability for scaling. Making use of or implementing an outboard processor or a scaler can raise the performance level to a much higher level for both video display and source components.

Buyers Guide to Home Theater Projectors

Buyers Guide to Home Theater Projectors
By Warren Thompson

Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the ainbow effect. The ainbow effect is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024x768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget. Soprano's is coming on right now! Time to go!

Film Projector Rentals

Film Projector Rentals
By Marcus Peterson

A film projector projects reels of film onto a screen to form a continuous image. Film projectors have the need to wind and unwind the reels and adjust the arms and distance. Despite the competition from video projection, film projectors have a niche market of buyers.

Film projector rental demand comes from residences, film festivals and university and school campuses.

Film projectors come with different widths such as 8mm, 16mm and 35mm. The type of projector depends on the space available and the number of audience. The demand for 35mm comes mostly from festivals while 8mm and 16mm find demand from other segments such as residences and student shows in universities.

Many of the rental companies are either owned by the universities or reside in the campuses. The demand for film projectors is cyclical as film festivals happen during a particular period of a year. Even for residences, the demand is usually in the summer months, when families like to have get-togethers outdoors.

The rental rates for projectors depend upon the type of films. 16mm projectors have a starting rental rate of $20 per day, 35mm at $50 per day. The total rental rates go up when we consider the screens and other accessories. Most of the a/v industry rental companies hold fewer stocks of film projectors. The rental companies in the university campuses charge lower fees for student groups.

Film projectors face severe competition from video projectors. New technologies such as DLP and audio/video storage media slowly make the conventional film based technologies obsolete. When compared with video projectors, film projectors lack features to control contrast and brightness. Even with cinema halls transitioning to digital forms of projection, film based projector manufacturers are dwindling and therefore are the rental industry of film based projectors.

How DLP Projectors Work?

How DLP Projectors Work?
By Paul Cris

DLP (Digital Light Processing) projectors can be attached with computers, DVD players, VCR players, HDTVs and video games. It comes in various models and with enhanced features. DLP Projectors are also called as Multimedia projectors.

In mid 1990s Texas Instruments developed Digital Light Processing. DLP technology is based on DMD or Digital Micromirror Device. It is a switch, which controls the intensity, and placement of projected light via 4,80,000 mirrors. In a DLP-based display there are unlimited colors. You can control the saturation and clarity to make bright video as clear as you want. The DMD is coordinated with a graphic signal, a light source and a projection lens.

The micromirrors of DLP are fixed on a panel of small pivots, which enable them to slant either way. If it slants towards (on) light source it creates bright pixels on the screen and when it slants the other way (off) it creates darker pixels. When the bit-stream image code enters the semiconductor, the semi conductor directs the switch to on or off. If the switch remains on more times than off, it reflects a light gray pixel. Otherwise it reflects darker gray pixel.

In DLP systems white light is passed through a color wheel and it runs to the surface of the DMD panel. The color wheel converts the white light into red, green and blue. From these three colors a DMD chip can create 16.7 million colors. So a 3-DMD chip DLP system can create a mammoth 35 trillion colors. Then our eyes understand these colors and see an image.

DVD is a type of optical storage technology. Digital form of storage has completely replaced magnetic storage media like floppy disks. DVD is the acronym of Digital Versatile Disk and is better than CD in terms of audio and video quality. It is versatile and can be played in DVD players and computers.

DVD comes in various formats like DVD-R and DVD-RW, the R and W means read and write capacity of the disc. DVD players can play units can play a various units audio and video discs in different formats such as CD-R, CD-RW, mp3 and VCD. DVD players also support jpeg formats. Some DVD players have recording features.

DVD projectors are used to project audio and video images from DVD players and VCR. Care should be taken to ensure that the medium used is compatible with the DVD projectors. For instance, some DVD projectors dont support inputs from computers. While hiring DVD projectors, the accessories are DVD players, DVDs, sound systems and screens. These have to be carefully chosen. They also come with IR remote controls and laser pointers. The output can be fed into high resolution plasma and LCD displays.

Some of the branded names available for rental come from 3M, Canon, BenQ and InFocus. They are available in different models with different features. DVD projectors can be hired for as low as $80 and the accessories are charged with their own rental rates. The rental companies require credit card information and an ID. Since DVD projection is of high quality, the major segment is the corporate and business houses for their presentation requirements.

DVD projectors, because of their versatility and high quality, are used in wedding receptions and other staging events such as conferences and trade shows. DVD projectors have made the film projectors less attractive.

Build Your Own LCD Video Projector

Build Your Own LCD Video Projector
By Andrew Seltz

Mix big screen home theater dreams with a skimpy budget and you have the makings of a fantastic do-it-yourself project. Just think of how impressed all your friends will be watching blockbuster movies on a video projector you made with your own 2 hands.

It was just these motivations that landed me in front of my web browser digging for information for this project. There are a lot of cheesy websites that promise the moon and sell you a plastic magnifying lense and the instructions to stick a television into a box and put this lens on the front. You will get an image, but it will look like you made it yourself. - dark, and blurry.

Is there any way to make this work? The short answer is yes. A video projector is essentially a high resolution LCD video screen with a really bright light shining through it and a projector lense enlarging onto the screen. New portable models use very tiny, and expensive, LCDs along with sophisticated light sources and high quality lenses. If you are willing to end up with a projector that isn't quite so tiny, you can scavenge the parts you need from an LCD computer monitor and add some electronic components and relatively inexpensive lenses. For $200-$500 you should be able to create a high resolution bright projector that will really impress your friends.

The parts you need are:

• High resolution LCD computer monitor
• Projector lens (and possibly 2 fresnel lenses depending on the plans you use)
• Cooling fan(s) - bright lights get hot when you shove them in a box
• Bright lightsource (one approach to the project is to use an old overhead projector)
• Electrical power supply

There are dozens of websites with step-by-step plans for free or for sale. Some sell parts that you'll need. Two that I've found to be excellent are LumenLab and the DIY Projector Company. They both sell parts and parts kits. LumenLab sells a very nicely produced PDF instruction guide with detailed plans. DIY offers plans free, but expects that you'll buy one of their kits to actually make the projector. They both use the LCD in a box with a lamp approach.

InventGeek has a great article explaining the whole process in depth including the theory behind projectors. I recommend you check it out. The DenGuru website shows another approach to the project. They use an old overhead projector for both the lightsource and lens. You strip the LCD panel out of its frame and lay it on the projector like a transparency. Ugly, but it works! Check out their tutorial.

Break out your toolkit and get busy - and let's be safe out there people!

Video Projectors Advice On Choosing The Right Model For Home Or Business

Video Projectors - Advice On Choosing The Right Model For Home Or Business
By Steve Jones

As video projectors become more affordable then more people are using them both at work and at home. You might be thinking that projectors are all alike and the more you spend the better it will be. Well this is not strictly true. The more expensive projectors will be of a higher standard, but you might not experience any benefit if you do not choose the correct model. This is why we have written this article to try and guide you and help you choose the model most suited to you.

Before any purchase it is important to have a think about what you will be using it for and in what kind of environment. The business user will have very different requirements to someone wanting to set up a home cinema. Companies are now marketing hybrid projectors that claim to be able to be used for both home cinema and business. These two environments are very different though and will need projectors designed specifically to be able to handle these two very different uses. As you read the rest of the article you will begin to understand what you need to look out for when purchasing your video projector.

LCD or DLP

Both are excellent formats and which you choose will depend on your use. The business user will be more suited to an LCD projector due to the increased brightness. The home user on the other hand would be better to opt for a DLP projector as these will give a more cinematic experience.

Brightness

Think about the level of ambient light in the room where you will be using your projector. In the home cinema you will hopefully have control of the level of light so this will not be an issue. If you are using a room at home that has ambient light then you will need to opt for a brighter projector. In the business arena you are likely to be presenting in very bright rooms with standard office lighting and windows. A good projector for business use will need to have a high brightness level.

Brightness is measured in ANSI lumens. For home cinema you should be looking at projectors that have around 700 ANSI lumens brightness and for business projectors you will need between 1000 and 1500.

Color

The color, gray-scale performance, and video playback, are only really important to the home user as they will give more natural and detailed videos.

Contrast

There is no point spending money on a high contrast video projector for business use or use in a room at home that has significant ambient light as your eyes will not notice the benefit. If you have a dedicated cinema room at home then it will be worth looking at projectors with contrast ratios of 400:1 or higher. If you are looking for a projector for business use then there is no point by one with a ratio of higher than 400:1

Portability

This will probably only be an issue for a business user. If you travel around a lot and take your projector with you then the more compact and light the better. It is possible to buy extremely light projectors.

The home user may not be concerned too much with size and weight, but it is worth considering how you will set your projector up at home. Will it be fixed to the ceiling or on a stand? If you have it on the ceiling you should look for a projector which comes with a remote control as this will make adjusting settings a lot easier.

We hope that this look at the differences with video projectors will help you make your decision.

Benefits of a HighQuality LCD Projector Lamp for Your LCD

Benefits of a High-Quality LCD Projector Lamp for Your LCD
By Enreek Kahlon

In terms of multimedia presentations, LCD projectors have proven to provide impressive image quality and high resolutions. However, if your projector suddenly fails to work and you need to present a proposal with potential clients, it could cause your business to lose money, or worse, it could cause your job.

The most common problem of projectors is the sudden burn out of LCD projector lamps. Fortunately, these LCD projector lamps can be easily replaced. Although anyone can replace the lamps for your LCD projector, choosing the lamp can be an overwhelming task. You need to ensure that the type of lamp you buy is compatible with your projector.

A high-quality LCD projector lamp should be able to operate for over 4,000 hours. However, the measurements of lamp life are not reliable because the lamp can still work, even if it becomes dimmer. For this reason, you need to check the peak lamp life listed in most manufacturers of LCD projector lamps, which provides users with information of the total brightness a particular lamp could provide.

Choosing a high-quality lamp for your LCD projector should be your first concern, instead of price. Compared to the affordable halogen lamps that last about 70 hours, metal halide lamps can work up to 500 hours. Meaning, the more expensive LCD projector lamp you choose, the longer-lasting life it would provide.

How to Choose an LCD Projector Lamp

There are only two types of lamps used in LCD projectors metal halide and tungsten halogen. In order to choose a quality lamp, you have to understand how each one works.

A metal-halide lamp provides better brightness, but lower consumption of power. Be aware that lamp wattages do not reflect the brightness. Metal-halide LCD projector lamps are more efficient because it could provide your projector with a very white light until the end of its life.

On the other hand, tungsten-halogen lamps produce whiter lights because it runs at a higher temperature than other lamps. Although the white light will become yellow during its lifetime, it provides a longer lamp life because of its low-pressure and high temperature features.

Although metal-halide LCD projector lamps are more expensive, they could provide over 2,000 hours compared to the tungsten-halogen lamps 70 hours of operation. Be aware that lamps of your projectors could last longer when you operate them in economy mode, which automatically cools down when the projector becomes idle.

LCD Projectors for Sale

LCD Projectors for Sale
By Ken Marlborough

Do you want to continue to be at the cutting edge of technology with high-end presentation products? Do you want to keep your audience glued to you and the vibrant graphics and clear characters of your presentation? Whether you are presenting to 10 or 10,000 people, there is bound to be an LCD projector that is perfect for you. Here is a simple guide on what to look for when you want to purchase one.

Resolution

The first consideration to look for when shopping for an LCD projector is resolution. Resolution is the number of light dots (called pixels) per square inch of the image produced. The higher the number of the pixels, the clearer and tighter your image will be. Also, if your LCD projector of choice is high in resolution, the image you can broadcast can be expanded to greater degrees. If your lecture or presentation is heavy on graphics and high quality color, or if you need to present to a large crowd, then you will need an LCD projector with high resolution.

Brightness

Since the image your LCD projector will broadcast is projected with a high-powered light bulb, you will also want to consider how bright a projection you will need. Again, the brighter the image you project, the farther away it can be seen. This is an important consideration for people thinking of presenting to large and small groups.

Price and other considerations

These projectors do not come cheap, so price is a major consideration. If your company is small, a desktop projector with resolution the size of your typical computer monitor should suffice. Also, be sure to check on compatibility issues. Is the projector you want compatible with your hardware? If it is not, you may wind up with a very expensive lamp. Finally, ask about user support. Does it come with a warranty? If it does, how long is the coverage? Is there a technical support hotline you can call if you have trouble with your projector? All these things will factor into getting an LCD projector that suits your needs.

These projectors generally have a specially designed auto focus lens, which allows for quick and easy switching between multiple screens with minimal user adjustments. Their automatic color correction feature provides true color reproduction even when projecting onto colored or textured walls for a perfect presentation anywhere.

While choosing the right LCD projector for an auditorium, the dimensions of the auditorium, the ambient light conditions and the distance where the projector will be placed from the screen should considered and projectors whose specifications exceed the requirements should be considered.

Computer Projector Rentals

Computer Projector Rentals
By Eric Morris

Computer projectors have become indispensable for company presentations. The audio-visual impact alone really drives a difficult point home.

Most computer renting companies also provide computer projectors. However renting a computer projector can be complex as projectors are custom-designed for different operating systems and even processors. Before renting, a company will ask what computer will be used: iMac computers use different types of projectors than IBM. The resolution and the video card of the computer also matter in the final output on the projector.

Another factor is the room size and lighting. Rooms that cannot be darkened would preferably need a LCD screen. LCD screen would also Plasma monitors would suffice if the assembly will be small. The size of the monitor would also depend on the size of the room and how far the people are going to sit from the display. Sound quality is also affected by the size of the room.

Before renting a projector, inform the renting company whether videos are to be shown or just slides and transparencies.

Computer projector renting companies usually setup the entire audio-visual equipment when a rental order is placed. Get the whole thing checked, for video and sound quality. Also try out the projector before hand, especially if there are laptops to be used. The renting company also undertakes the dismantling of the unit after the program is completed.

Renting companies allow their projectors to travel with the business if necessary. For portable projectors, insist on a case to pack the equipment. Also the projector itself should be lightweight, not weighing more than 10 pounds.

Costs of renting computer projectors are tax deductible if they are used for business. Companies may pay for them using checks or their company credit card.

6 Steps To Getting A Perfect Projector

6 Steps To Getting A Perfect Projector
By Timothy Wong

Follow this step-by-step article, and you won't go wrong.

1. Low-cost projectors normally make two main sacrifices. The brightness, which is measured in ANSI lumens, will be relatively low, and the native resolution will be limited to 800x600. Neither one of these will be serious drawbacks providing you lower your room lights, draw the blinds, and there isnt too much detail in your slides. Home cinemas definitely do not require anything more. Movie enthusiasts are more likely to be concerned with the lamp life and replacement cost.

2. Image quality is obviously important but very hard to test based on specifications. A high contrast (500:1 or above) ratio adds depth to the picture and is one substantial benefit of projectors based on digital light processing (DLT), as opposed to the older LCD technology. Do keep in mind though; the optics and color balance cannot be assessed without consulting a review.

3. Where you will be using your projector also needs to be put into question. Size and weight are obviously very important if youll be moving the piece around a lot. If portability is a factor, aim for a projector that is less than 3kg. Small rooms will demand a quiet (below 33dB) projector with a flexible throw distance or how close or far away the screen must be. Most projectors can rotate or mirror their image to cope with ceiling mounting or rear projection.

4. Make sure the projector you are looking at covers all the signals you might want to feed it with. Common video formats are supported by almost all projectors, but high-resolution VGA signals arent. High quality pictures will only display at their best only on pricier projectors, with a 1,024x768 native resolution.

5. Top-of-the-range projectors have 2,000 ANSI lumens brightness or more to overpower brightly lit rooms. They also come with a handful of useful features that make presentations look and sound slicker, as well as making it easier for the presenter. Anti-theft features may also be something worth looking into.

6. After sales Warranty and support is definitely a must, especially for the heavier users. Make sure you have access to bulb replacements (or replacement service).

Recommended Minimum Specs-

Native Resolution: 800x600 Brightness: 1,100 ANSI Lumens Contrast Ration: 500:1 Lamp Life: 2,000 hours Check: Weight, throw distance and noise.

What You Should Know About Buying Projector From Ebay Or Online Auction

What You Should Know About Buying Projector From Ebay Or Online Auction
By Clifford Tan

Many people wish to purchase a home projection theater system but still have to work within the constraints of a budget. Can a budget projector be a viable alternative? While a thousand dollars is still a lot of money, it really is not so much to pay for a good home theater projection system. A good home theater will provide years of entertainment from movies, to video and computer games to vacation picture slideshows. How though, can someone find a projector for less than one thousand dollars? How can anybody find a quality projector that also fits the category of a cheap projector? How can they make sure it is going to suit their needs?

One of the most obvious options is through auctions. This is a very difficult way to purchase a projector. The main reason is that all you can do is asking questions of someone who has already proven that they are a motivated seller, proven by the very fact that they have posted the projector on an online auction. Bidding online can be done with some level of confidence though. It is very easy to conceive of getting a very good multimedia projector for less than a thousand dollars in this manner.

Making sure you ask the questions you want answered is the first challenge in finding a home theater projector online. While this may sound easy enough, it really is not when you think about it. For example:

Buyer: Why are you selling your projector?
Seller: Because I am thinking about buying a new projection system. (Thinking, looking, considering all are terms to make the buyer beware)

Why would this simple question and answer dissuade someone from actively bidding on this projector? Take a moment to look at it more closely. The seller obviously wants to sell the projection unit that they currently own. But why do they want to sell it is the relevant question. The answer states that they are looking, considering, thinking about, or otherwise contemplating the purchase of a new system, this is not to say that they are actively in the process of purchasing a new system. This in turn, should lead the prospective purchaser of the online auction projector to ask themselves, and the seller, a series of other questions. Why are they selling the projector without having found a new one they are sure of?

While there are literally thousands of different combinations of this simple question and answer red flag, the key is the same in all of them. If the seller will not give specifics then buyer beware. It is better to lose a bid on a high quality projection theater system than it is to win even with a low bid for a damaged projection unit. The cost of repairs, while relevant in the long term of projector life is important; it should not have to be a factor when purchasing a new projector, no matter where it is bought.

Things to look for that will indicate it may in fact be a quality cheap projector usually are some type of upgrade on the part of the seller. While they may still be very happy with the unit they are selling, somehow or another they have managed to put together the money for a new home theater projector display and setup. Another factor may very well be that they were uninformed when they made the purchase.

One key to making a new projector purchase is making sure the store where it is purchased has a good return policy. Ambient lighting, (while the most common factor, is not the only one) will cause many projector displays that look great in the store display to function less than ideally in the purchasers home. It may well be that the seller did not ask the right questions when they bought the projector and they cannot return it. This happens more than most people want to admit with any number of products, not just with projection units. Asking the correct questions can make it easier to figure out if the projector will be right for your needs or not.

Ask the seller about the picture quality of the projection unit they are selling. If the seller is specific and gives you an answer saying that it is not what they expected, there could be other mitigating factors that will make this ideal for you to get a great deal on a great projection system for well under one thousand dollars.

Find out what kind of projection screen they are using. If the projection screen is not ideally suited to the home theater projector they purchased, that could be a point in favor of the buyer. Sometimes a person will spend a great deal of money on a projector and use the blank space on the wall to project the multimedia displays. If the projector shuts off or flickers. This could be an indication that the projector is fine (For the moment) but has been set up somewhere that is either too dusty for the projection unit filters to keep up or it has been set up somewhere that there is not sufficient airflow and the projection unit is overheating. Find out specific details about where the projector is. Do not be afraid to ask questions. The worst that can happen is that they will refuse your bid and save you money. Not a bad deal really, and certainly better than ending up with a home projector that will not work at all or that needs substantive repairs.

If you know that the projector is functioning well but the picture quality is not what it should be, there could well be another frequently encountered problem. This is known as the keystone effect. Most projection units come with keystone adjustment features. The concept is to allow the optic lenses to be adjusted horizontally and vertically. While this can be a great benefit in some projectors, some home theater systems will become quickly inundated with the keystone effect. To make a long story short, the screen and the projector have pixels. The pixels are little concave shaped areas where light is projected and displayed. The keystone effect occurs when the pixels on the screen are not correctly aligned with the pixels being projected from the projection unit. This will greatly detract from the viewing pleasure and often causes unpleasant sensations such as headaches to the viewer.

If a buyer is willing (And well informed enough) to ask specific questions they should get specific answers. If the seller refuses to be specific or to discuss details, than do not bid. Ever! The well-informed buyer will never end up with a seriously damaged projector, and just may, if they ask the right questions, end up with a high quality home theater projection system for well under a thousand dollars.

LCD Projector Reviews

LCD Projector Reviews
By Ken Marlborough

Product reviews are more popular now as manufacturers seek new ways to entice customers to spend their hard-earned money on their products. Many companies use consumer product reviews as advertisements, and little wonder why they do. Manufacturers do not have to pay extra to advertising companies for expensive ad campaigns. However, the credibility of product reviews has been criticized. A review that simply reads I really loved your product! Keep it up! and leaves it at that is not what you should expect from a product review. With regard to buying something as expensive as an LCD projector, being informed about your prospective purchase is very important. Here is an article on how to look for an LCD projector based on product reviews.

Technical information

An informative product review should deal with information that is directly linked to the product being reviewed and it should be specific regarding its details and specifications. A typical informative product review on LCD projectors should contain the following information: resolution, brightness, price, and potential usage (sometimes called the for-whom section).

Resolution is how clear and tight the graphics being displayed are and they are usually determined by the number of dots per inch (dpi). A higher resolution means tighter graphics and less pixellation (the grainy quality in some images).

Brightness is exactly that--how bright the image being projected is. This determines from how far away the image can be seen. The brighter the image, the farther away it can be seen.

Reviews that include information on potential usage are particularly helpful. This section allows you to find out specifically if the product you want is applicable to your needs. Simply parallel yourself or your company with any one of the list of potential users, and you will be able to tell at a glance if the product is what you are looking for or not.

The reputation of the reviewer

Anybody can write a product review that is why you should be careful when taking advice from product reviews. If the review you are reading comes from a reputable Web site or magazine, then you should be in good hands. Be sure to do some research on the party doing the review before you take advice from them, or you may end up with a very expensive paperweight.
