About your monitor
Plug-and-Play
You can install the monitor in 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 necessary. For more information about changing the
LCD monitor quality and pixel policy
During the LCD monitor manufacturing process, it is normal 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 LCD Monitor 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, or shoulder pain from using
the monitor for long periods of time, it is recommended to:
• Set the distance of the screen between 20 in. to 28 in. (50 cm - 70 cm) from
your eyes.
• Blink frequently to moisten your eyes or wet your eyes with water after
prolonged usage of the monitor.
• Take regular and frequent breaks for 20 minutes every two hours.
• Look away from your monitor and gaze at a distant object at 20 ft away for at
least 20 seconds during the breaks.
• 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.
• 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.
• Let your upper arms rest naturally on both sides.
• Ensure that your feet are resting flat on the floor.
• When sitting, ensure that the weight of your legs is on your feet and not on the
front portion of your seat. Adjust your chair 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.
