Re:Gah, DLP (Score 1)

Some people have these problems with DLPs because of the color wheel. It is a wheel with different color translucent segments that spins very fast and produces color for the dmd. Some backlit/rear proj/front proj DLP devices use three chips, one for R G and B, but they are usually very expensive. Additionally, if this device is backlit by LED light, it is possible to use the LED to produce the color and eliminate the color wheel also. Traditionally, the faster spinning color wheels produce less ill-effect for the users (Headaches, Rainbows or RBE.)
