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.
