Image Persistence
Image persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT
monitors, LCD monitors’ image persistence is not permanent, but a still image being displayed for a long period of time should
be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image
was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle, or turn off the monitor when not in use.
Ergonomics
English
CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN
REDUCE EYE, SHOULDER, AND NECK FATIGUE. CHECK THE
FOLLOWING 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. Get 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.
English−7
• 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.
For more detailed information on setting up a healthy work environment, write to the American National Standard for Human
Factors Engineering of Computer Workstations - ANSI/HFES 100-2007 - The Human Factors Society, Inc. P.O. Box 1369,
Santa Monica, California 90406.
Cleaning the LCD Screen
• When the LCD Screen is dusty, please gently wipe with a soft cloth.
• Clean the LCD screen surface with a lint-free, non-abrasive cloth. Avoid using any cleaning solution or glass cleaner!
• Please do not rub the LCD Screen with hard or coarse material.
• Please do not apply pressure to the LCD Screen surface.
• Please do not use OA cleaner as it will cause deterioration or discoloration on the LCD Screen surface.
Cleaning the Cabinet
• Unplug the power supply.
• Gently wipe the cabinet with a soft cloth.
• To clean the cabinet, dampen the cloth with a neutral detergent and water, wipe the cabinet and follow with a dry cloth.
NOTE: DO NOT clean with benzene thinner, alkaline detergent, alcoholic system detergent, glass cleaner, wax, polish cleaner,
soap powder, or insecticide. Rubber or vinyl should not be in contact with the cabinet for an extended period of time.
These types of fluids and materials can cause the paint to deteriorate, crack or peel.

For HDCP Content
HDCP is a system for preventing illegal copying of video data sent over a digital signal. If you are unable to view material via
the digital inputs, this does not necessarily mean that the monitor is not functioning properly. With the implementation of HDCP,
there may be cases in which certain content is protected by HDCP and might not be displayed due to the decision/intention of
the HDCP community (Digital Content Protection, LLC). HDCP video content is generally commercially produced Blu-rays and
DVDs, television broadcast, and streaming media services.

Image Persistence
Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs
when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, the image persistence
on LCD monitors is not permanent, but single still image being displayed for a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image
was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular
intervals whenever the screen is idle, or turning off the monitor when not in use.
