Plug and Play capability
You can connect the monitor to 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.

• 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.
• 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
