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.
* Zero power consumption in OFF mode can only be achieved by disconnecting the
main cable from the monitor.
