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 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 material)
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
