Power Management Modes

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.

The OSD operates only in the normal operation mode. If you press any button in the active-

off mode, the following message is displayed:

*Zero power consumption in OFF mode can only be achieved by disconnecting

the AC mains cable from the monitor.

**Maximum power consumption with maximum luminance.

Plug-and-Play

You can install the monitor in any Plug-and-Play-compatible system. The monitor

automatically provides the computer system with its extended display identification data

(EDID) using display data channel (DDC) protocols so the computer can configure itself

and optimize the monitor settings. Most monitor installations are automatic; you can select

different settings if desired. For more information about changing the monitor settings, see

Operating the Monitor.

LCD Monitor Quality and Pixel Policy

During the LCD monitor manufacturing process, it is not uncommon for one or more pixels

to become fixed in an unchanging state which are hard to see and do not affect the display

quality or usability. For more information on LCD Monitor Pixel Policy, see Dell support site

at: http://www.dell.com/support/monitors.
