When presenters have worked for hours to create digital images that look sharp and crystal clear on their monitors, they expect to have the image look as sharp and clear projected on the screen. This grainy, pixilated effect occurs because the horizontal and vertical spaces between the liquid crystals in the projector block the light. The new DLP and micro-mirror technologies combine to create significantly smaller spaces between its mirrors. What's more, DLP technology handles motion images superbly, because the mirrors move at over 1,000 times per second. That is fast enough for the 30 frame per second video frame rate standard in televisions.
Contrast is the difference between the projected white and black images.
When your projector has an optimum contrast ratio, your images will be sharper and more readable. Similarly, a low contrast ratio results in dull, washed out images.
