The \fIlevel\fP 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. .SH "RETURN VALUES" .TP 15 TRUE The .I DPMSForceLevel function always returns TRUE. .SH ERRORS .TP 15 BadValue A level other than DPMSModeOn, DPMSModeStandby, DPMSModeSuspend, or DPMSModeOff was specified. .TP 15 .SM BadMatch DPMS is disabled on the specified display. .SH "SEE ALSO" .BR DPMSCapable (__libmansuffix__), .BR DPMSInfo (__libmansuffix__), .BR DPMSGetTimeouts (__libmansuffix__), .BR DPMSSetTimeouts (__libmansuffix__)
