Safety instructions  
CAUTION: Use of controls, adjustments, or procedures other than  
those specified in this documentation may result in exposure to shock,  
electrical hazards, and/or mechanical hazards.  
• Place the monitor on a solid surface and handle it carefully. The screen is  
fragile and can be damaged if dropped or hit sharply.  
• Always be sure that your monitor is electrically rated to operate with the AC  
power available in your location.  
• Keep the monitor in room temperature. Excessive cold or hot conditions can  
have an adverse effect on the liquid crystal of the display.  
• Do not subject the monitor to severe vibration or high impact conditions. For  
example, do not place the monitor inside a car trunk.  
• Unplug the monitor when it is going to be left unused for an extended period  
of time.  
To avoid electric shock, do not attempt to remove any cover or touch the  
inside of the monitor.

• Power and OSD buttons lock.  
• Security-lock slot.  
• < 0.3 W in Standby Mode.  
• Optimize eye comfort with a flicker-free screen and ComfortView feature  
which minimizes blue light emission.  
WARNING: The possible long-term effects of blue light emission from  
the monitor may cause damage to the eyes, including eye fatigue,  
digital eye strain, and so on. ComfortView feature is designed to reduce  
the amount of blue light emitted from the monitor to optimize eye  
comfort.  
*The 4 ms gray-to-gray mode is achievable in Extreme mode to reduce visible motion blur  
and increased image responsiveness. However, this may introduce some slight and notice-  
able visual artifacts into the image. As every system setup and every user's needs are differ-  
ent, we recommend that users experiment with the different modes to find the setting that  
is right for them.

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 that 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.

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 www.dell.com/pixelguidelines.

Ergonomics  
CAUTION: Improper or prolonged usage of keyboard may result in  
injury.  
CAUTION: Viewing the monitor screen for extended periods of time  
may result in eye strain.  
For comfort and efficiency, observe the following guidelines when setting up and  
using your computer workstation:  
• Position your computer so that the monitor and keyboard are directly in front  
of you as you work. Special shelves are commercially available to help you  
correctly position your keyboard.  
To reduce the risk of eye strain and neck/arm/back/shoulder pain from using  
the monitor for long periods of time, we suggest you to:  
1. Set the distance of the screen between 20 to 28 in. (50 - 70 cm) from your  
eyes.  
2. Blink frequently to moisten your eyes or wet your eyes with water after  
prolonged usage of the monitor.  
3. Take regular and frequent breaks for 20 minutes every two hours.  
4. Look away from your monitor and gaze at a distant object at 20 feet away  
for at least 20 seconds during the breaks.  
5. Perform stretches to relieve tension in the neck, arm, back, and shoulders  
during the breaks.  
• Make sure that the monitor screen is at eye level or slightly lower when you  
are sitting in front of the monitor.  
• Adjust the tilt of the monitor, its contrast, and brightness settings.  
• Adjust the ambient lighting around you (such as overhead lights, desk lamps,  
and the curtains or blinds on nearby windows) to minimize reflections and  
glare on the monitor screen.  
• Use a chair that provides good lower-back support.  
• Keep your forearms horizontal with your wrists in a neutral, comfortable  
position while using the keyboard or mouse.  
• Always leave space to rest your hands while using the keyboard or mouse.  
• Let your upper arms rest naturally on both sides.  
• Ensure that your feet are resting flat on the floor.  
• When sitting, make sure that the weight of your legs is on your feet and not on  
the front portion of your seat. Adjust your chair's height or use a footrest if  
necessary to maintain a proper posture.

the monitor or cause personal injury.  
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 when 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:  
1. Turn Off both your computer and the monitor.  
2. Unplug the video cable from the 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.  
NOTE: The message may slightly differ, depending on the connected  
input signal.  
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 perform the previous procedure,  
check your video controller and computer, because your monitor is functioning  
properly.

roubleshooting  
     
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.  
To run the built-in diagnostics:  
1. Ensure that the screen is clean (no dust particles on the surface of the  
screen).  
2. Press and hold Button 4 for about 4 seconds until a pop menu appears.  
3. Use Button 1 or Button 2 to select the diagnostic tool  
and use Button 3  
to confirm. A gray test pattern appears at the beginning of the diagnostic  
program.  
4. Carefully inspect the screen for abnormalities.  
5. Press Button 1 again to change the test patterns.  
6. Repeat steps 4 and 5 to inspect the display in red, green, blue, black, white,  
and text screens.  
7. Press Button 1 to end the diagnostic program.
