# [DESCRIPTION](#DESCRIPTION)

The **DPMSEnable** function enables Display Power Management Signaling (DPMS) on the specified *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 [**DPMSSetTimeouts**(3)](/man/os/libxext/DPMSSetTimeouts.3). All physical screens are affected by **DPMSEnable** at the same time.

If **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.
