Power Management Modes
If you have VESA’s DPM™ compliance display card or software installed in your PC,
the monitor 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 monitor automatically resumes
functioning. The following table shows the power consumption and signaling of this
automatic power saving feature.
