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.

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 the Monitor.
Universal Serial Bus (USB) Interface
This section gives you information about the USB ports that are available on 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 Dell Monitor Quality and Pixel
Policy, see Dell Support site at: http://www.dell.com/support/monitors.

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:
22
•
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 antistatic 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.

Troubleshooting
WARNING: Before you begin any of the procedures in this section, follow 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. To ensure proper Self-Test
operation, remove all digital cables from the back of 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, one of the dialogs
shown below will continuously scroll through the screen.

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 and Button 4 on the front panel simultaneously for 2
seconds. A gray screen appears.
4
Carefully inspect the screen for abnormalities.
5
Press Button 4 on the front panel again. The color of the screen changes to red.
