Entire working of cathode ray tube digital projectors is a lot like CRT television set. These projectors can be configured with one RGB color tube which has three colors green, red and blue having a single lens, one black & white tube by using a rotating color wheel or three RGB color tubes with three lenses. Projectors having cathode ray tubes are often bulky thats why these are the basic best projectors for fixed installations.
