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 display
settings. Most display installations are automatic; you can select different settings if desired. For
more information about changing the display settings, see Operating the Display.

LCD Display Quality and Pixel Policy
During the LCD display 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 Display Pixel Policy, see Dell support site at: http://
www.dell.com/support/monitors.

Troubleshooting

WARNING: Before you begin any of the procedures in this section, follow the
Safety Instructions.

Self-Test
Your display provides a self-test feature that allows you to check whether your display is
functioning properly. If your display and computer are properly connected but the display screen
remains dark, run the display self-test by performing the following steps:
1. Turn off both your computer and the display.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test
operation, remove all digital and the analog cables from the back of computer.
3. Turn on the display.
The floating dialog box should appear on-screen (against a black background), if the display
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, one of the dialogs shown below will
continuously scroll through the screen.

56 |

Troubleshooting

4. This box also appears during normal system operation, if the video cable becomes
disconnected or damaged.
5. Turn off your display and reconnect the video cable; then turn on both your
computer and the display.
If your display screen remains blank after you use the previous procedure, check your video
controller and computer, because your display is functioning properly.

Troubleshooting

| 57

Built-in Diagnostics
Your display has a built-in diagnostic tool that helps you determine if the screen abnormality you
are experiencing is an inherent problem with your display, or with your computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable is unplugged
and the display is in self-test mode.

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 display. The display
then goes into the self-test mode.
3. Touch and hold
for 5 seconds. A gray screen appears.
4. Carefully inspect the screen for abnormalities.
5. Touch
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, touch
again.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool, the display
is functioning properly. Check the video card and computer.

Maintenance Guidelines
Cleaning Your Display
WARNING: Before cleaning the display, unplug the display power cable from
the electrical outlet.
CAUTION: Read and follow the Safety Instructions before cleaning the display.
For best practices, follow these instructions in the list below while unpacking, cleaning, or
handling your display:
• 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 display. Avoid using detergent of any kind as
some detergents leave a milky film on the display.
• If you notice white powder when you unpack your display, wipe it off with a cloth.
• Handle your display with care as a darker-colored display may get scratched and show
white scuff marks more than a lighter- colored display.
• To help maintain the best image quality on your display, use a dynamically changing screen
saver and turn off your display when not in use.
