Computer users may complain of eyestrain and headaches after prolonged use. Users are
also at risk of physical injury after long hours of working in front of a computer. Long
work periods, bad posture, poor work habits, stress, inadequate working conditions,
personal health and other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis
or other musculoskeletal disorders. The following symptoms may appear in the hands,
wrists, arms, shoulders, neck or back:
•numbness, or a burning or tingling sensation
•aching, soreness or tenderness
•pain, swelling or throbbing
•stiffness or tightness
•coldness or weakness
If you have these symptoms, or any other recurring or persistent discomfort and/or pain
related to computer use, consult a physician immediately and inform your company’s
health and safety department.
The following section provides tips for more comfortable computer use.
Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest,
or raising your sitting height to achieve maximum comfort. Observe the following tips:
•refrain from staying too long in one fixed posture
•avoid slouching forward and/or leaning backward
•stand up and walk around regularly to remove the strain on your leg muscles

•placing your display in such a way that the side faces the window or any light
source
•minimizing room light by using drapes, shades or blinds
•using a task light
•changing the display’s viewing angle
•using a glare-reduction filter
•using a display visor, such as a piece of cardboard extended from the display’s
top front edge
•Avoid adjusting your display to an awkward viewing angle.
•Avoid looking at bright light sources, such as open windows, for extended
periods of time.

To reduce the need for adjustment for different modes, the monitor has
default setting modes that are most commonly used as given in the table
below. For optimum adjustment, the user is suggested to perform the
Auto etup under Windows “Full creen“ pattern or using the pattern in
the floppy disk provided. When none of the mode is matched, the user can
store their preferred modes in the user modes. The monitor is capable of
storing up to 9 user modes. The only condition to store as a user mode is
the new display information must have 1 KHz difference for horizontal
frequency or 1 Hz for vertical frequency or the sync signal polarities are
different from the default modes.
