NAME

     dpms -- VESA BIOS DPMS driver

SYNOPSIS

     device dpms

DESCRIPTION

     The dpms driver uses the VESA BIOS to manage an external display during suspend and resume.  When the machine suspends, the dpms driver turns
     the external display off.	When the machine resumes, it restores the display to its state when the driver was first loaded.

SEE ALSO

BUGS

     The VESA BIOS DPMS calls do not provide any way to identify a particular display or adapter to manipulate.  As a result, this driver may have
     unexpected results on systems with multiple displays and/or adapters.

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.
       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.
