Plug-And-Play; Lcd Monitor Quality And Pixel Policy; Ergonomics - Dell S2722DGM User Manual

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

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

Ergonomics

WARNING: Improper or prolonged usage of keyboard may result in injury.
WARNING: 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.
