ABSTRACT:
A video projector generates a black screen. Further, the video projector reduces the brightness of the light source which reduces the power level of the video projection system. Since the light source's power is reduced, less heat is generated by the video projector and the video projector's cooling fan may be slowed down. As a result, the video projector produces less noise.
