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.
