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 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.

Cleaning your monitor

Please carefully follow these guidelines when cleaning the monitor:

•    Always unplug the monitor before cleaning.

•    Use a soft cloth to wipe the screen and cabinet front and sides.

If the system has multiple sources of power, disconnect power from the system by
