• 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.

• To avoid electric shock, do not attempt to remove any cover or touch the inside of the
monitor.

• Read these instructions carefully. Keep this document for future reference. Follow all
warnings and instructions marked on the product.

• Certain monitors can be wall mounted using the VESA mount that is sold separately. Ensure
to use the correct VESA specifications as mentioned in the wall mounting section of the

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: https://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 screen about 20 to 28 in. (50-70 cm) from your eyes.

2. Blink frequently to moisten or rewet your eyes when working with 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/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.

• 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.

20 | About your monitor

• 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.

Handling and moving your display

To ensure the monitor is handled safely when lifting or moving it, follow the guidelines
mentioned below:

• Before moving or lifting the monitor, turn off your computer and the monitor.

• Disconnect all cables from the monitor.

• Place the monitor in the original box with the original packing materials.

• Hold the bottom edge and the side of the monitor firmly without applying
excessive pressure when lifting or moving the monitor.

• When lifting or moving the monitor, ensure the screen is facing away from you and
do not press on the display area to avoid any scratches or damage.

• When transporting the monitor, avoid any sudden shock or vibration to it.

22 | About your monitor

• When lifting or moving the monitor, do not turn the monitor upside down while
holding the stand base or stand riser. This may result in accidental damage to 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:

• Use a clean cloth that is slightly dampened with water to clean the stand assembly, the
screen, and the chassis of your Dell monitor. If available, use a screen-cleaning tissue or
solution suitable for cleaning Dell monitors.

• After cleaning the surface of the table, ensure that it is thoroughly dry and free from any
moisture or cleaning agent before placing your Dell monitor on it.

CAUTION: Do not use detergents or other chemicals such as benzene, thinner,

ammonia, abrasive cleaners, alcohol or compressed air.

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.

WARNING: Do not spray the cleaning solution or even water directly on the surface
of the monitor. 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 damages 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 residual 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 o 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.
