Power Management Modes
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.

The OSD functions only in the normal operation mode. When any button is pressed in
the Active-off mode, the following message will be displayed:
Activate the computer and the monitor to gain access to the OSD.
NOTE: The message may be slightly different according to the connected input
signal.
* Zero power consumption in OFF mode can only be achieved by disconnecting the
main cable from the monitor.
** Maximum power consumption with max luminance, and USB active.
