If you have VESA’s DPM-compliant video 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.
