Lcd Monitor Quality And Pixel Policy; Ergonomics - Dell S2522HG User Manual

NOTE: The USB ports on the monitor work only when the monitor is
turned on or in Standby mode. If you turn off the monitor and then turn
it on, the attached peripherals may take a few seconds to resume
normal functionality.

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

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.
