PROJECTION TV – HOME SWEET HOME THEATER
For the Hollywood luxury of the panoramic screen, projection TVs can suit a wide variety of rooms and budgets. They're capable of creating excellent quality and wall sized images. Projection TVs used to be bulky, cathode ray tube(CRT) sets. Today's models have lightened up and slimmed down with liquid crystal display(LCD), digital light processing (DLP) or liquid crystal on silicon (LCoS) imaging. The newer models with digital technologies can create a large brilliant picture.
Projection TV’s come in two configurations: Front–projection and Rear-projection.
Front-projection:
This is the kind of projection you are familiar with from movie theaters. A front-projection system uses a stand alone screen of up to 100 inches or more diagonally. The projector is separate and placed on a table or stand, or can be ceiling mounted. Be sure to place the projector the distance from the screen recommended by the manufacturer for the best quality image. To increase the size of the image you want, you must increase the distance between the projector and screen. A projector with a zoom feature will also help with this. Be prepared to provide your own sound system as well. Most projectors come with no audio, or, if included, usually of poor quality.
For television viewing you will need an external tuner such as a cable connection or satellite box. You can hook up a DVD player for movies. Some come with a DVD feature, but these may not offer HD resolution. You can also project the picture on a white wall, but whichever you use, wall or screen, you will need to be able to totally darken the room as any light will wash out the projected image. Some less expensive units are available without high definition. If you are setting up the ultimate home theater experience, we recommend the HD models.
Rear-projection:
In rear-projection televisions, the image is created then enlarged on the back of the screen, rather than the front. Often, these resemble traditional televisions. The projector is usually contained within the television itself, although there are systems that can use a projector and special screen. They are available in many sizes but the most popular is the 50 to 59 " screen range. Most new sets are 1080p models, with 1920x1080 resolution. They are capable of displaying all 1,080 lines in the HD format known as 1080i.
These rear-projection are generally the lowest cost for the BIG picture. However, they can also be very large or bulky when compared to the new thin TVs, so consider the space you have to allot to your projection television. With micro-display models, you will need to replace a bulb from time to time. The replacement process is easy, as, say, replacing a light bulb. However, the bulbs can be costly. A few sets now have longer lasting bulbs or those that last the life of the TV.
