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.
* Zero power consumption in off mode can only be achieved by disconnecting the
main cable from the monitor.

About your monitor | 25
Plug and play capability
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 system 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 your 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 Dell Monitor Quality and Pixel
Policy, see Dell Support site at: www.dell.com/support/monitors.
Maintenance guidelines
Cleaning your monitor
WARNING: Before cleaning the monitor, unplug the monitor power cable from
the electrical outlet.
CAUTION: Read and follow the Safety instructions before cleaning the monitor.
For best practices, follow the instructions in the list below while unpacking, cleaning
or handling your monitor:
∞ To clean your anti-static screen, lightly dampen a soft, clean cloth with water.
If possible, use a special screen-cleaning tissue or solution suitable for the anti-
static coating. Do not use benzene, thinner, ammonia, abrasive cleaners or
compressed air.
∞ Use a lightly-dampened, warm cloth to clean the monitor. Avoid using
detergent of any kind as some detergents leave a milky film on the monitor.
∞ If you notice white powder when you unpack your monitor, wipe it off with a
cloth.
∞ Handle your monitor with care as a darker-colored monitor may get scratched
and show white scuff marks more than a lighter-colored monitor.
∞ To help maintain the best image quality on your monitor, use a dynamically
changing screen saver and turn off your monitor when not in use.

functioning properly. If your monitor and computer are properly connected but the
monitor screen remains dark, run the monitor self-test by performing the following
steps:
1. Turn off both your computer and the monitor.
2. Disconnect all video cables from the monitor. This way, the computer doesn’t
have to be involved.
3. Turn on the monitor.
If the monitor is working correctly, it detects that there is no signal and one of the
following message appears. While in self-test mode, the power LED remains white.
