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.

•Power Charging Port- the port with battery icon; supports fast current
charging capability if the device is BC1.2 compatible.
NOTE: USB 3.0 functionality requires a USB 3.0-capable computer.
NOTE: The monitor's USB interface works only when the monitor is On or in the
power save mode. If you turn Off the monitor and then turn it On, the attached
peripherals may take a few seconds to resume normal functionality.
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:
•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.

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:
1Turn off both your computer and the monitor.
2Unplug the video cable from the back of the computer.
3Turn 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.
4This box also appears during normal system operation, if the video cable becomes
disconnected or damaged.
5Turn 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.
Troubleshooting | 51
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:
1Ensure that the screen is clean (no dust particles on the surface of the screen).
2Unplug the video cable(s) from the back of the computer or monitor. The monitor
then goes into the self-test mode.
3Press and hold Button 1 on the front panel for 5 seconds. A gray screen appears.
4Carefully inspect the screen for abnormalities.
5Press Button 1 on the front panel again. The color of the screen changes to red.
6Inspect the display for any abnormalities.
7Repeat 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.
