WARNING: 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.

You can connect the monitor to any Plug-and-Play compatible computer. The
monitor automatically provides the computer with its Extended Display

the computer can configure itself and optimize the monitor settings. Most
monitor installations are automatic; you can select different settings, if required.

QD-OLED monitor quality and pixel policy
During the QD-OLED 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 about
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.
• Ensure 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.

CAUTION: Using chemicals for cleaning may cause changes in the
appearance of the monitor, such as color fading, milky film on the monitor,
deformation, uneven dark shade, and peeling of screen area.
Cleaner
Do use• Filtered or distilled water
• Neutral or alkali detergent (for example, dish soap) with water
• LCD/LED screen cleaner (without Acetone)
• Toluene/Acetone/Solvent
Don’t use
WARNING: Do not spray the cleaning solution or even water directly on
the monitor surface. Doing so will allow liquids to accumulate at the
bottom of the display panel and corrode the electronics resulting in
permanent damage. Instead, apply the cleaning solution or water to a soft
cloth and then clean the monitor.
NOTE: Monitor damage due to improper cleaning methods and the use of
benzene, thinner, ammonia, abrasive cleaners, alcohol, compressed air,
detergent of any kind will lead to a Customer Induced Damage (CID).
CID is not covered under the standard Dell warranty.
• 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.
• Common glass cleaner
• Household cleaning products
• Abrasive cleaning solution
• Cleaner containing hydrogen peroxide

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:
n off both your computer and the monitor.

NOTE: This dialog box also appears during normal operation, if the video
cable is disconnected or damaged.

Page 73
4. Turn off your monitor and reconnect the video cable; then turn on both
your computer and the monitor.
After performing the above steps, if the monitor displays no video output, then
the problem may be with the graphics card or the computer.
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. Move and hold the joystick left for five seconds. A gray screen appears
after one second.
3. Observe if the screen has any defects or abnormalities.
4. Press the joystick. The color of the screen changes to red.
5. Observe if the screen has any defects or abnormalities.
6. Repeat steps 4 and 5 to inspect the display in green, blue, black, and white
screens.
The test is complete when the white screen appears. To exit, press the joystick
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.

• Use the native resolution of
your monitor (3440 x 1440 at
60
Hz) or higher refresh rate.
• If the variable refresh rate
(VRR) of your device is turned
on, turn off variable refresh
rate (VRR).
• If you are using an NVIDIA
graphics card and G-Sync is
turned on, turn off G-Sync.
• If you are using an AMD
graphics card and Free-Sync is
turned on, turn off Free-Sync.
• Update the graphics card
driver and firmware to the
latest version.
• Change the cable connecting
the monitor to the computer. A
defective cable can cause the
signal to break while being
transmitted across the wire.
• Check the surroundings.
Electromagnetic fields can
cause screen flickering. If there
is another device plugged into
the same power strip as the
monitor, try to remove it.
• Set the screen to turn off after
a few minutes of screen idle
time. These can be adjusted in
Windows Power Options or
Mac Energy Saver setting.
• Alternatively, use a dynamically
changing screensaver.
• Perform the function of Pixel
Refresh or Panel Refresh. See
OLED Panel Maintenance.
