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.

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

Maintenance Guidelines
Cleaning Your Monitor
CAUTION: Read and follow the Safety Instructions before cleaning the
monitor.
WARNING: Before cleaning the monitor, unplug the monitor power
cable from the electrical outlet.
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.

Troubleshooting
WARNING: Before you begin any of the procedures in this section,
fol low the Safety Instructions.
Self-Test
Your monitor provides a self-test feature that allows you to check whether your
monitor is 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. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
The floating dialog box should appear on-screen (against a black background), if the
monitor cannot sense a video signal and is working correctly. While in self-test
mode, the power LED remains white. Also, depending upon the selected input, the
dialog shown below will continuously scroll through the screen.
NOTE: The message may be slightly different according to the
connected input signal.
4. This box also appears during normal system operation, if the video cable
becomes disconnected or damaged.
5. Turn Off your monitor and reconnect the video cable; then turn On both your
computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check
your video controller and computer, because your monitor is functioning properly.

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.
To run the built-in diagnostics:
1. Ensure 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 on the front panel 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.
