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 23
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 reflections. Adjust the monitor
tilt so that ceiling lights do not reflect on your screen.
• If reflected light makes it hard for you to see your screen, use an anti-glare filter.
• 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 materi-
al) directly in front of you to minimize turning your head while you are typing.
• Avoid displaying fixed patterns on the monitor for long periods of time to avoid image
persistence (after-image effects).
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, 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 60-75Hz
• Do not use primary color blue on a dark background, as it is difficult to see and may
produce eye fatigue to insufficient contrast
