Power management modes

If you have a VESA DPM™ compliant display card or software installed on your
computer, 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 to
function. The following table shows the power consumption and signaling of this
automatic power saving feature:
