Presenters who work for hours to create sharp, clear digital images on their monitors expect to have those images looking just as sharp and clear when projected on the screen. As a result, only about 70 percent of the projected light makes it through the LCD medium. With DLP technology, the spaces between the mirrors are significantly smaller, measuring only one micron, which is one-seventeenth the width of a human hair. As a result the MP2800 model projects over 90 percent of the light, virtually eliminating the screen door effect and projecting sharper, seamless images. DLP technology also handles motion images superbly, because the mirrors move at over 1,000 times per second, fast enough for the 30 frames per second video frame rate that is the television standard.
Contrast is the difference between the projected white and black images.
With an optimal contrast ratio, images become much sharper and more readable. A low contrast ratio results in dull, washed-out images. The MP2800 survives the same range of tests as Compaq's Armada line of notebook PCs. The units are dropped, shaken, beaten, and pressurized to simulate air travel. High durability is provided by a magnesium casing that is 20 percent stronger than plastic and 30 percent lighter than aluminum, providing a unique combination of light weight and ruggedness.
