26 | About your monitor
Plug-and-Play capability
You can connect the monitor to any Plug-and-Play compatible computer. The
monitor automatically provides the computer with its Extended Display
Identification Data (EDID) using Display Data Channel (DDC) protocols so that
the computer can configure itself and optimize the monitor settings. Most
monitor installations are automatic; you can select different settings, if required.
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 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, or shoulder pain from
using the monitor for long period, we recommend 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 that is 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.
