Question

How does a projector work?                           

Answer 1

A projector works by displaying an image onto a surface through the use of light. The light source comes from a bulb or LED built into the projector and is directed through a lens that focuses the light onto the surface. The image is transmitted to the projector via HDMI or VGA cables.

Answer 2

A projector works by shining a bright light through an image or video onto a screen or surface. The light passes through a series of lenses and other optical components that focus and shape the image. The image is typically generated by a light source, such as a lamp or LED, and displayed using a digital or analog signal.
