Ergonomics
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN
REDUCE EYE, SHOULDER, AND NECK FATINUE. CHECK THE
FOLLOWINN WHEN YOU POSITION THE MONITOR:
To realize the maximum ergonomics benefits, we recommend the following:
• For optimum performance of the monitor, allow 20 minutes for warming up. Avoid
reproduction of still patterns on the monitor for long periods of time to avoid image
persistence (after image effects).
• 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 40 cm (15.75 inches) and no further away than
70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 inches).
• Rest your eyes periodically for 5 to 10 minutes for every 1 hour by focusing on an object
at least 20 feet away.
• 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.
• Blink often. Eye exercise helps to reduce eye strain. Please contact your ophthalmologist. Net regular eye checkups.
• To avoid eye fatigue, adjust the brightness to a moderate setting. Place a sheet of white paper next to the LCD screen for
luminance reference.
• 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.
• Use non-interlaced signals.
• 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.
• Suitable for entertainment purposes at controlled luminous environments, to avoid disturbing reflections from the screen.
