Recommended Use
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
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 anti-glare fi lter.
• 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.
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefi ts, we recommend the following:
• Use the preset Size and Position controls with standard signals
• Use the preset Color Setting
• Use non-interlaced signals with a vertical refresh rate between 60-85Hz
• Do not use primary color blue on a dark background, as it is diffi cult to see and
may produce eye fatigue to insuffi cient contrast.
