5. Power Management
If you have VESA DPM compliance display card
or software installed in your PC, the monitor
can automatically reduce its power consumption
when not in use. If an input from a keyboard,
mouse or other input device is detected,
the monitor will 'wake up' automatically. The
following table shows the power consumption
and signaling of this automatic power saving
