.SH DESCRIPTION
.LP
The 
.I DPMSEnable 
function enables Display Power Management Signaling (DPMS) on the specified 
.I display. 
When DPMS is enabled, DPMS will use the currently saved timeout values. It will 
trigger the appropriate DPMS power level based on the timeout values. Refer to 
.I DPMSSetTimeouts. 
All physical screens are affected by 
.I DPMSEnable 
at the same time.

If 
.I DPMSEnable 
is invoked on a display which has DPMS already enabled, or on a display which 
does not support DPMS, no change is made and no error is returned.
.SH "RETURN VALUES"
.TP 15
TRUE
The 
.I DPMSEnable 
function always returns TRUE.
