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.
