Power Management Modes
If you have VESA's DPM-compliant video card or software installed in your PC, the display can
automatically reduce its power consumption when not in use. This is referred to as power save
mode*. If the computer detects input from the keyboard, mouse, or other input devices, the
display automatically resumes functioning. The following table shows the power consumption
and signaling of this automatic power saving feature.
