subject: Some Rear Projection Lcd Tv Secrets_ [print this page]

The least expensive type of large TV is a rear-projection LCD

TV. Some projection TVs have three cathode-ray picture tubes

(CRTs), which are like smaller versions of the tubes used in

conventional sets. The images from those small tubes are

projected onto the back of a 40-inch to 60 inch plus screen,

giving them the name rear projection TV. Other rear projection

TV sets use LCD, digital light processing (DLP), or liquid

crystal on silicon (LCoS) technology in place of CRTs.

These high tech rear projection TV sets are thinner, lighter,

and as a result more expensive than comparable CRT-based

sets - but they produce a higher-quality picture.

Major brands of rear projection LCD TV sets include Hitachi,

Mitsubishi, Panasonic, Philips, RCA, Samsung, Sony, and

Toshiba. The most popular models are HD capable, and

there are three basic types of HD TVs.

So how do you choose the right rear projection LCD TV for

you and your viewing needs? First, consider the space you

have available before you worry about the screen size itself.

Most rear projection LCD TVs have screens measuring from

42 to well over 60 inches. You might be tempted to

purchase one of the biggest screens, which can span as

much as 70 inches or more, but first determine how much

floor space you can spare, and plan to view the TV from

around 7 to 10 feet away for optimal picture quality.

Also consider depth and price. Once you know how much room

you have, decide whether size or price is more important. CRT

-based sets are floor-standing models with deep cabinets

mounted on casters. Some take up as much space as an

armchair or loveseat. Many rear projection LCD TV sets are

tabletop units, or you can buy a separate stand for a few

hundred dollars.

Then focus on picture quality. The best rear projection LCD TV

sets deliver very good picture quality with HD content and good

picture quality for DVDs and regular TV programming. Rear

projection LCD TV screens provide much better picture quality

than CRT models.

Also check the viewing angle. Some rear projection LCD TV

sets display a better image from off-center than older sets did,

which is important if your TV will be watched by several people

at the same time. Before buying a particular model, see how

the picture looks if you step off to the side or move up and

down. With some rear projection LCD TV sets you'll see a

dimmer, washed-out image as your viewing position angles

away.

Once you've made your choice, it pays to think about whether

you want an extended warranty on your rear projection LCD TV.

While extended warranties may not be worth it for most products,

they may be for high-priced TVs. Because rear projection LCD TV

sets are expensive, check into the cost of a service plan. Find

out whether in-home service is covered and whether a replacement

is provided if your rear projection LCD TV can't be repaired.
