SPECIAL NOTES ON LCD MONITORS

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 effective pixels of 99.99% or more. It may include
blemishes of 0.01% or less such as a missing pixel or a pixel lit all of 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 hours.
