Contrast Ratio
Contrast
Ratio is the difference between the whitest white and the darkest
black colors that the display can show. Generally speaking, the
greater the contrast the better the screen and the subtlety of colors
it can display.
Contrast
ratio is often used when describing projectors. A high contrast
ratio, such as 3000:1, signifies a better color representation (bright
images will appear better against a darker background) than a lower
contrast ratio, such as 1500:1. A 3000:1 contrast means 3000 times
brighter than black. Typically, you want to purchase a projector
with a 2500:1 or greater contrast ratio for home theater applications.
However for business you might not need as high of contrast. Below
is examples of different contrast ratio's.
Low
Contrast
When contrast is low, images appear washed out. Parts of the image
may become difficult to see clearly. Projectors with contrast ratios
of less than 500:1 typically provide low contrast.

Medium Contrast
When a projector provides good contrast, images are clear and attractive.
Projectors with contrast ratios ranging from 500:1 to 1200:1 typically
provide medium contrast.

High Contrast
With high contrast, images are ultra crisp with vibrant colors.
Projectors with contrast ratios exceeding 1200:1 typically provide
high contrast. DLPTM (DDR) technology projectors currently offer
these high contrast ratios.
