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.
