DPMS stands for Display Power Management Signaling.
DPMS is a standard set by the Video Electronics Standards Association (VESA) that provides guidelines for communication between the display adapter and the display. It defines the way various signals are sent from the display adapter to the display to control power management states.
There are four power management states in the DPMS specification: On, Standby, Suspend, and Off. Brief descriptions of the DPMS states are provided below.
On: The display is fully on, and the video image is active.
Standby: The display is functional and may be in an energy conserving state, and the video image is blank.
Suspend: The display is functional and in an energy conserving state, and the video image is blank.
Off: The display is non-functional, and the video image is blank.
In order to enable DPMS on a system, the display, display adapter, BIOS, and operating system must support the DPMS standard.
