Monitor Specifications

The following sections give you information about the various power management modes and pin assignments for various connectors for your monitor.

Power Management Modes

If you have VESA's DPMS compliance display card or software installed in your computer, the monitor automatically reduces its power consumption when not in

use. This is referred to as Power Save Mode. If input from keyboard, mouse or other input devices is detected by the computer, the monitor will automatically

"wake up". The following table shows the power consumption and signaling of this automatic power-savingfeature:

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