To avoid a projector from running with full lamp power, BenQ created the No Source Detected feature to lower the projector lamp brightness to 30% after the projector has remained unconnected to a display source for more than three minutes. When inactive, the MS504 keeps power consumption to a minimum of 0.5W standby power further lowering your total cost of ownership.
