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.

• < 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.

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

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

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.

About your monitor
• Vary your work activities. Try to organize your work so that you do not have to
sit and work for extended periods of time. Try to stand or get up and walk
around at regular intervals.
• Keep the area under your desk clear of obstructions and cables or power
cords that may interfere with comfortable seating or present a potential trip
hazard.

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.

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.

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.
