Front Projection TVs
Some just call them projectors and they sure have come a long way
A front-projection TV is literally a projector, a small box that projects its images forward onto a screen where the images are viewed. Like any projector the viewing area is variable depending on the positioning of the projection unit. Most fron- projector TVs have an optimal size range, usually around 100". The first, most obvious advantage to a the front projector is the massive viewing area. Compare a front projector to any rear-projector, direct-view or flat-panel TV made and the front projector can easily dwarf it. The front projector is indeed the choice for home theater with emphasis on the true theater experience.
The front projector is going to be a rather small box that can be mounted on a stand or directly onto your ceiling to limit the footprint the device leaves in the room. It will have to project onto a screen, so there must be a dedicated light-colored screen that maximizes the light given off by the projector to accentuate color images. Because the process requires light traveling across the room, the image quality will be degraded with ambient lighting. The room should be as close to totally dark as possible to get the best image quality from your front projector. Anytime front projector is considered for your home theater you must consider your control over ambient lighting. If this is a living room with a large window that cannot be completely blocked, then other display types should be considered. Front projectors make perfect display devices for the basement rec room or a dedicated home theater room where you have total control over the lighting.
Despite the obvious drawbacks of room configuration, the other most common reason for potential front-projector users turning to rear projection TVs is the price. While it's true there are incredible deals to be had with rear-projection TVs these days, front-projection TVs can be ordered online usually for a fraction of the cost of what you've seen in stores. There is a whole cottage industry of online support and support communities to answer your questions on front projection. Many deals can be had ordering online and, unlike rear projectors, front-projection TVs can be shipped at relatively low cost.
