A Projector is a device designed to take an image from a video source and project it as faithfully as possible onto a screen or other surface. Projectors are used in a variety of different ways; they are enjoyed by home theater enthusiasts due to their ability to project movies and television programs onto a screen much larger than even the biggest TV available, and used in the corporate setting to project information onto screens large enough for rooms filled with people to see. Projectors come in a variety of different shapes and sizes and are produced by many different companies.
