LCD projector

An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector. To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon panels – one each for the red, green and blue components of the video signal. As polarized light passes through the panels (combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image.

   Most laptops offer three video settings:
   • local video (only) - computer video is only displayed on the laptop
   • projector video (only)- computer video is 'sent' to another display device such as an LCD projector, CRT monitor, or plasma display
   • local video AND projector video - computer video is simultaneously sent to both the local laptop display, as well as being sent to another device such as an LCD projector, CRT monitor, or plasma display.
5. Focus and adjust the picture size
