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:

VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption

Normal operation Active Active Active White 35 W (maximum) **
Active-off mode Inactive Inactive Blanked Amber Less than 0.5 W

Switch off - - - Off Less than 0.5 W
The OSD functions only in the normal operation mode. When any button is pressed in the Active-off mode, one of the following messages will be displayed:

21 W (typical)

Activate the computer and the monitor to gain access to the OSD.

NOTE: This monitor is ENERGY STAR®-compliant.

* 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.
