22 | About your monitor
Plug-and-play capability
You can connect the monitor to any Plug-and-Play compatible system. 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 as 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: 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 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.
