Power Management Modes
If you have VESA’s DPM compliance display card or software installed
in your PC, the monitor automatically reduces its power consumption
when not in use. This is referred to as Power Save Mode. If the computer
detects input from keyboard, mouse, or other input devices, the monitor
automatically resumes functioning. The following table shows the power
consumption and signaling of this automatic power-saving feature:
