Meaning of THREE-BEAM PROJECTOR in English

A computer/video projector having three color beams (guns) to project computer and/or video images on the wall or large screens. These are generally the top of the line in terms of projection quality and lowest in line in terms of portability. Most of these have scan converters to convert computer RGB into NTSC images. Early models could only scan CGA images from PC computers. Modern versions can scan almost any type of computer display, although they may require skilled technicians to adjust the display whenever a computer is first connected to the projector. These projectors are very popular as ceiling mounts in electronic classrooms. (See also Projection , LCD , and Graphics adapter )
