About Your Monitor  
Universal Serial Bus (USB)  
This section gives you information about the USB ports available on your monitor.  
NOTE: Up to 2 A on USB downstream port (port  
with lightning icon) with  
BC 1.2 compliance devices; up to 0.9 A on the other 3 USB downstream ports.  
Your computer has the following USB ports:  
2 upstream - bottom  
4 downstream - 2 at left side, 2 at bottom  
Power Charging Port - the one on the left side (Port with  
lightning icon);  
supports fast current charging capability if the device is BC 1.2 compatible.  
NOTE: The monitor’s USB ports work 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.

About Your Monitor

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.

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 and the analog 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.

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.

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.
