Video Projector Information


Video Projectors take an input signal (usually a computer, dvd player or live camera feed) and project them onto a large screen. They can be CRT, LCD or DLP.


CRT - Uses three CRT's (red, green and blue) to produce image and provide light for projection. Convergence and focus of image at screen plane.

Pros: Long service life, superior black levels, can play interlaced material natively, no rainbow effect and high-end models can accurately display hi-res material with accurate color reproduction.

Cons: Large, heavy, expensive. Cannot be moved without setup. Limited light output requires darkened room.


LCD - Uses 3 transmissive LCD panels to modulate an external light source. Convergence is established during manufacturing; the only user optical adjustment is focus (and zoom if applicable).

Pros: Smaller, lighter, less expensive than CRT design. Can easily be moved from site to site with no setup required. Brighter models do not require complete room darkening. Models with zoom lenses permit flexible location in room. Low maintenance requirements.

Cons: The use of fixed resolution LCD panels requires pixel mapping/scaling to accommodate all computer graphics standards which are not at the native resolution of the projector. This may result in the loss of some detail information in the display. Pixelation of the image may be objectionable for some uses. Light distribution of the projected image may be uneven (bright center, dark edges). The color temperature of the lamp may adversely affect the color of images, especially video.

DLP - A trademark owned by Texas Instruments. Uses one, two or three DMD (Digital Micromirror Device) chips containing a matrix of pixel-sized movable mirrors which reflect light from an external source through a common lens to the screen. Projectors employing fewer than three DMD chips use compromised color components or a rotating color filter wheel to produce color images.

Pros: High efficiency produces a bright image with a smaller lamp than LCD design (or brighter images with the same size lamp). Good image contrast and color reproduction in 3-chip models.

Cons: One- and two-chip designs produce color and temporal artifacts--especially in moving video. Fixed pixel design requires scaling/pixel-mapping to deal with all but native resolution sources.
