Power Management Modes  
If you have VESA’s DPM-compliant video 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.

About Your Monitor

21  
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 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: 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 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 video cables from the back of computer.  
Turn on the monitor.  
3
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.

disconnected or damaged.

Troubleshooting  
 
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
Make sure that the screen is clean (no dust particles on the surface of the screen).  
Unplug the video cable(s) from the back of the computer or monitor. The monitor  
then goes into the self-test mode.

Press and hold Button 1 for 5 seconds. A gray screen appears.  
Carefully inspect the screen for abnormalities.  
Press Button 1 on the front panel again. The color of the screen changes to red.  
Inspect the display for any abnormalities.  
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

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.
