4 Main things while buying a
Projector
1). There are 3 types of projector - LCD, DLP, CRT
2). The Lumens output (brightness) of lamp - 800-1000 is
good for LCD, DLP at 1000 is good. Dont get it to high or colours will look
poor, less than 1500 is really needed for good colour reproduction.
3). The Resolution. For optimal picture make sure to get XGA
or WXGA. A cheaper method is VGA/SVGA, but if you can get XGA or higher you
wont regret the moeny spent.
4). A very key point is contrast ration. 300:1 and less is
poor meaning blacks look dark grey. 700:1 and higher is good giving darker
blacks and whiter whites (contrast is difference between these two). 1000:1 +
is excellent. (source:
