VESA Display Power Management Signaling

VESA Display Power Management Signaling (or DPMS) is a VESA standard that defines how to signal the H-sync and V-sync pins in a standard SVGA monitor to trigger the monitor's power saving capabilities.

DPMS defines four modes, normal, standby, suspended and off. In off some power may still be drawn in order to power indicator lights. The standard is:
