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 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 your 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 Dell Support site at www.dell.com/pixelguidelines.

Ergonomics

CAUTION: Improper or prolonged usage of keyboard may result in in-

jury.

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, or shoulder pain from using
the monitor for long period, we recommend you to:

1. Set the distance of the screen between 20 in. to 28 in. (50 cm - 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.

20 │ About your monitor

• 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.

• Let your upper arms rest naturally on both sides.

• Ensure that your feet are resting flat on the floor.

• When sitting, ensure 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.

• 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 that the monitor is handled safely when lifting or moving it, observe the
following guidelines:

• 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 that the screen is facing away from
you. 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.

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

Maintenance guidelines

Cleaning your monitor

WARNING: Using improper methods when cleaning the monitor can

result in a physical damage to the screen or the body of your Dell
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 the Dell monitor screen, lightly dampen a soft, clean cloth with water.
If possible, use a special screen-cleaning tissue or solution suitable for the Dell
monitor screen.

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

thinner, ammonia, abrasive cleaners, or compressed air.

CAUTION: Using chemicals for cleaning may cause changes in the ap-

pearance 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.

About your monitor │ 23

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 dark-colored monitor may get scratched
and show white scuff marks more than a light-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.
