Some Rear Projection Lcd Tv Secrets_
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.
