Selecting
a Home Theater Projector
FIVE
POINTS TO PONDER IN SELECTING A HOME THEATER PROJECTOR:
- PRICE:
Most people are surprised at just how reasonable
projector prices have become. In most cases, projectors
are more cost-effective than a big screen TV or plasma.
(Projector systems take up less space, as well.) The
key, of course, is to get all the features and quality
at a price that fits your budget, and the folks at National
Projector can do just that.
- BRIGHTNESS:
Many people believe that brighter is better, but for
home theater it's not the case. A typical home theater
setting with low ambient
light will require a projector from 800 lumens
to 1300 lumens depending on the screen size. A four
to six foot wide screen would need a projector with
at least 800 lumens and a seven to ten food wide screen
would need about 1300 lumens. A screen about 12 feet
wide would need about 2,000 lumens.
- RESOLUTION:
Resolution is the number of pixels a projector displays.
SVGA
(800x600) has a resolution of 800 pixels wide by 600
pixels vertical and XGA
is 1024x768. Most standard televisions have about 480
lines. DVD
disks have an image quality of only 480 lines so an
SVGA projector would do quite well for standard TV and
DVD viewing. HDTV
on the other hand, has 720 or 1080 lines of resoulution,
so in most cases an XGA
projector would projected a better image than SVGA.
- ASPECT
RATIO: Television, old 3-gun projectors and most
standard LCD
and DLP video projectors have an aspect
ratio of 4:3 which means the projected image will
be 4 units wide by 3 units high. Widescreen projectors
have an aspect ratio of 16:9. HDTV is displayed in the
16:9 format. If most of your viewing will be HDTV and
widescreen formats then a widescreen projector is a
good choice but if you will be using your projector
to view movies in 4:3 format or will also be using your
projector for powerpoint presentations then a standard
4:3 format projector might be the best choice.
- LAMP
LIFE: Most projectors have a lamp
life of 2,000 hours but some units are rated at 4,000
or even 8,000 hours. Some projectors for home theater
have a dual mode setting which will reduce the light
output but increase the lamp life.
