ABSTRACT:
A system for saving power used by a video screen including a comparator comparing the red, green blue signals to a reference signal and when all of these signals fall below a reference signal and stay below the reference signal for a preset period of time, power to the video monitor is interrupted until the red, blue or green signals are restored. When the power is applied, power is maintained during a stabilizing period.
