Recommended Use
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE MONITOR:
• For optimum performance, allow 20 minutes for
warm-up.
• Adjust the monitor height so that the top of the
screen is at or slightly below eye level. Your eyes
should look slightly downward when viewing the
middle of the screen.
• Position your monitor no closer than 16 inches
and no further away than 28 inches from your
eyes. The optimal distance is 20 inches.
• Rest your eyes periodically by focusing on an
object at least 20 feet away. Blink often.
• Position the monitor at a 90° angle to windows and other light sources to
minimize glare and refl ections. Adjust the monitor tilt so that ceiling lights do
not refl ect on your screen.
• If refl ected light makes it hard for you to see your screen, use an antiglare fi lter.
• Clean the LCD monitor surface with a lint-free, non-abrasive cloth. Avoid using
any cleaning solution or glass cleaner!
• Adjust the monitor's brightness and contrast controls to enhance readability.
• Use a document holder placed close to the screen.
• Position whatever you are looking at most of the time (the screen or reference
material) directly in front of you to minimize turning your head while you are
typing.
• Avoid displaying fi xed patterns on the monitor for long periods of time to avoid
image persistence (after-image effects).
• Get regular eye checkups.
