Projection TVs
If you're thinking about assembling a home theater system, you may be
looking at large screen televisions as the heart of your system.
Projection TV could give you the size that you want -- CRT screens
generally top out at 40" (101 cm) or so, and at that size, they are
huge and heavy.
Plasma screens can be bigger than that and still
manageable, but they can be extremely expensive. Projection TV
technology can create large screen sizes at a reasonable price.
Or maybe you need to equip a room, like a classroom or conference
room, for multimedia presentations with a large audience. A
projection TV gives you a lot of flexibility and is usually much
better than the standard combination of a 35mm slide projector,
overhead projector and TV/VCR.
Finding the right projector is
easier than you might imagine. There are hundreds of projectors
currently on the market. The sharpness and clarity of the picture on
the screen is determined by a projector's resolution.
Resolution is
simply the number of pixels (or "picture elements") the projector
uses to create the image. The more pixels it uses, the "higher" the
resolution. Resolution is usually quoted in two numbers, such as
"800 x 600," where the first number refers to the number of pixels
from side to side across the screen, and the second number refers to
the number of pixels vertically from top to bottom.
Projectors come
in a wide range of light output. All other things being equal, the
brighter the projector, the more it costs. When it comes to "optimum
brightness" the rule is simple: get the brightest projector you can
afford.
