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

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 touch 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.

WARNING: Before you begin any of the procedures in this section, follow the  
.
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 (white connector) and the Analog (blue connector)  
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.

or  
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.

Troubleshooting  
 
3. Press and hold Button 1 and Button 4 on the side panel simultaneously for 2  
seconds. A gray screen appears.  
4. Carefully inspect the screen for abnormalities.  
5. Press Button 4 on the side 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 4 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.
