Special notes on LCD monitors
The following are normal with the LCD monitor and do not indicate a problem.
• Due to the nature of the fluorescent light, the screen may flicker during
initial use. Turn off the power switch and then turn it on again to make
sure the flicker disappears.
• You may find slightly uneven brightness on the screen depending on the
desktop pattern you use.
• The LCD screen has 99.99% or more effective pixels. It may include
blemishes of 0.01% or less such as a missing pixel or a pixel lit all the time.
• Due to the nature of the LCD screen, an afterimage of the previous screen
may remain after switching the image, when the same image is displayed
for hours. In this case, the screen is recovered slowly by changing the image
or turning off the power switch for a few hours.
iii

• Give your eyes regular breaks by looking away from the monitor and
focusing on a distant point.
• Blink frequently to keep your eyes from drying out.
Display
• Keep your display clean.
• Keep your head at a higher level than the top edge of the display so your
eyes point downward when looking at the middle of the display.
• Adjust the display brightness and/or contrast to a comfortable level for
enhanced text readability and graphics clarity.
• Eliminate glare and reflections by:
• 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.
Developing good work habits
Develop the following work habits to make your computer use more relaxing
and productive:
• Take short breaks regularly and often.
