.SH DESCRIPTION
.LP
The

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.
