What is a Projector?
Projectors are devices that display images or video by projecting light onto a flat surface, such as a wall or screen, creating a large, easy-to-see picture. They are commonly used in classrooms, offices, and home theatres to show presentations, movies, or games at sizes much bigger than a typical TV. Projectors work by shining a powerful light through or off a digital image source and using a lens to focus it outward, and their image quality depends on factors like brightness, resolution, and the lighting in the room.
