What is the difference between the projector I have at the office and the projectors used for home theater?
Projectors used for presentations are typically designed to be as bright as possible and to display data from a laptop with the most clarity. Business projectors such as these are usually in a 4:3 aspect ratio – they project an image close to a square in shape. Home theater projectors are optimized for video – meaning that they might not be as bright as a data projector, but the quality of the projected image has a much improved contrast and color accuracy. Most home theater projectors are in a 16:9 aspect ratio – a widescreen format. While some data projectors may say they will project 16:9, it usually means they will just display black bars on the top and bottom and, in turn, project widescreen content in a lower resolution.
