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.

• 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 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.

Standard for Human Factors Engineering of Visual Display Terminal Workstations – ANSI-HFS

Standard No. 100-1988 – The Human Factors Society, Inc. P.O. Box 1369, Santa Monica,
