The DPMSDisable function disables Display Power Management Signaling (DPMS) on the specified display. When disabled, DPMS sets the display to DPMSModeOn. If DPMSDisable is invoked on a display with DPMS already disabled or on a display which does not support DPMS, no change is made and no error is returned.
The DPMSDisable function always returns TRUE.
