The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.

The contrast ratio is a measure of how much light the projector can pump out. A high contrast ratio is especially important for daylight use.
The contrast ratio for the Dell S2309W is 1000:1.
A 12,000:1 contrast ratio is good, but a 50,000:1 would be better.
1500:1 is the better contrast ratio
Contrast ratio isn't standardized, so manufacturers can fudge the numbers. Consider, however, a contrast ratio over 600.
The contrast ratio of the ViewSonic Pj551 LCD Projector is 400:1.
compression ratio=uncompressed image size/compressed size
Aspect Ratio If an aspect ratio of an image is changed the image will be distorted either vertically or horizontally
