The DPMSForceLevel function forces a DPMS capable display into the specified power level. The level must be one of following four states: DPMSModeOn, DPMSModeStandby, DPMSModeSuspend, or DPMSModeOff. Values other than these will result in a BadValue error. If DPMS is disabled on the display, trying to set the power level on the display will result in a BadMatch protocol error.
The DPMSForceLevel function always returns TRUE.
A level other than DPMSModeOn, DPMSModeStandby, DPMSModeSuspend, or DPMSModeOff was specified.
DPMS is disabled on the specified display.
