For business use or a true theater experience at home, a multimedia (LCD or DLP) projector can be connected to a DVD or VCR player, cable or satellite TV receiver, video game console, camcorder, or computer. HDTV capable projectors which offer highest quality images are now becoming more affordable.
Business projectors require portability, so the lighter weight models that are compatible with the resolution of the source (such as a notebook computer) are usually best for that purpose, although other factors such as image brightness and the kind of projection screen used are also considerations. Ceiling mounts are available for permanent installations.
Home theater projector choices are not limited by weight, so other features such as native or widescreen format, pixel resolution, brightness and contrast levels, available room size, and cost are more important. Additional equipment, such as a projection screen, will enhance the home theater experience.
LCD (Liquid Crystal Display) projectors tend to be brighter and have more color intensity. In addition, LCos (Liquid Crystal on Silicon) models are a new technology that have exceptional contrast levels. Generally less expensive than DLP models.
DLP (Digital Light Processing) projectors have pixels that are close together, important for smother video images with higher contrasts. They require fewer components, so are usually more portable.
Home theater projectors need to have good resolution and lower brightness levels (less eye strain) for optimal viewing in darker and smaller rooms. Wide screen models are especially good for showing widescreen movies and HDTV programs.
Home theater projectors are usually lower in price than business projectors since they do not need to be portable and must be affordable to individuals. Additional equipment, such as a projection screen or a ceiling mount, will enhance the home theater experience.
DLP (Digital Light Processors) projectors offer the high resolution (with less pixelation) and contrast brightness required for high definition images. There can be a problem with a "rainbow effect", however, where each color can be seen individually on the DLP display.
LCD (Liquid Crystal Display) projectors have better color saturation, sharper images, and lower prices than DLP models, but may have a "screen door" effect, where more pixelation is evident in the display. LCos (Liquid Crystal on Silicon) models are a new technology that have exceptional contrast levels.
