Turn off the powerswitch and then turn it on again to make the flicker disappear.• 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(caused by a missing pixel or a pixel that is always lit).• When the same image is displayed for hours on end, its afterimage may remain after switching to anew image. When this happens, the screen will recover slowly by changing the image. Turning theLCD monitor off for several hours will also correct this problem.
