16 | About your monitor
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 that 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: www.dell.com/support/monitors.

Built-in diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if the screen abnormality
you are experiencing is an inherent problem with your monitor, or with your computer and
video card.
NOTE: You can run the built-in diagnostics only when the video cable is unplugged
and the monitor is in self-test mode.
3 4 51 2
To run the built-in diagnostics:
1 Make sure that the screen is clean (no dust particles on the surface of the screen).
2 Unplug the video cable(s) from the back of the computer or monitor. The monitor
then goes into the self-test mode.
3 Press and hold Button 1 for 5 seconds. A gray screen appears.
4 Carefully inspect the screen for abnormalities.
5 Press Button 1 on the front panel again. The color of the screen changes to red.
6 Inspect the display for any abnormalities.
7 Repeat steps 5 and 6 to inspect the display in green, blue, black, white, and text
screens.
The test is complete when the text screen appears. To exit, press Button 1 again.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the
monitor is functioning properly. Check the video card and computer.

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 these 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, soft 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.
