Mitsubishi - DLP Projector - 1080p - HDTV - 16:9

LCD projectors create images through a liquid crystal display and are the most modern form of projection equipment. Overhead projectors are older projectors for hard copy transparencies. DLP , or Digital Light Processing projectors are of the same generation as LCD and offer high quality resolution and brightness. CRT projectors are older technology and based on three color light projection.

Type of technology that is used to project the images.

Projector brightness is measured in ANSI lumens. ANSI stands for "American National Standards Institute", who created a scale by which to measure the overall brightness value for projectors. The measurement represents the average value of 9 points on the projected screen image. The higher the ANSIv lumens value the brighter and sharper the projected image will be. \r\nWith a measurement of less than 1000 lumens, viewing can be hard unless in a darkened room. With a measurement of more than 3000 lumens, and it may be possible to see even in a sunlight filled room. There are several additional variables to consider as well as lumens, such as lamp bulb type, LCD technology and contrast ratios. If any of these variables is adjusted, it will make two projectors with the same lumens measurement display images of different quality. For example, a projector with a halogen lamp will appear darker than a projector with a metal-halide bulb.

The ratio between whitest white and the blackest black. A greater contrast means the greater the ability of the projector to show subtle color details even in light rooms. There are two separate measurements of contrast ratio: Full On/Off contrast is the measurement of light out when the projector displays a all white image (Full on) compared to the light output of a full black image (Full off).The second is the ANSI (American National Standards Institute) contrast; this is measured by projecting 16 alternating black and white rectangles. The average light output from the white rectangles is divided by the average light output of the black rectangles to determine the ANSI contrast ratio. Be sure you are comparing the same measurement standard when comparing contrast ratio of projectors.

Native resolution refers to the resolution of the computer output signal via the projector. Usually, the input signal (native) from a computer is automatically converted to the projector's own resolution. For this conversion process, the resolution is achieved by hardware/software image manipulation called re-scaling.

Platform describes the compatibility a projector may or may not have. If you are buying a projector as an add on to a computer, it is important to purchase a projector of the same platform.
