CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR
CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK
THEFOLLOWING WHEN YOU POSITION THE MONITOR:
• 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 12 inches and no
further away than 28 inches from your eyes. The optimal
distance is 24 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 your monitor regularly. Use a lint-free, non-abrasive cloth and a non-alcohol, neutral, non-
abrasive cleaning solution or glass cleaner to minimize dust.
• Adjust the monitor’s brightness and contrast controls to enhance readability.
CAUTION

2-11
• 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 benefits, we recommend the following:
• Adjust the Brightness until the background raster disappears
• Do not position the Contrast control to its maximum setting
• Use the preset Size and Position controls with standard signals
• Use the preset Color Setting and Sides Left/Right controls
• Use non-interlaced signals with a vertical refresh rate between 75-160Hz
• Do not use primary color blue on a dark background, as it is difficult to see and may produce eye
fatigue due to insufficient contrast
