Image resolution
Brightness	2200 ANSI Lumens	A standard for measuring light output, used for comparing projectors. Unfortunately, there are enough variables, that the eye will often disagree radically with the ANSI rating.

Contrast (full on/off)	400 :1	The contrast is the relationship between the brightest possible output, and the darkest possible output.
Standard Resolution	1024x768 XGA	All projectors have a native or true resolution. This is the standard but most projectors support other resolutions. A projector is best viewed in the standard resolution.
Maximum Resolution		Most projectors automatically accept images that are of greater resolution than the native (true) resolution of the projector.
Aspect Ratio	4:3	The most popular aspect ratio is 4:3 (4 by 3). Early television and computer video formats are in a 4:3 aspect ratio, which means that the width of the image is 4/3 times the height.
