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.

placing your display in such a way that the side faces the window or
any light source
minimizing room light by using drapes, shades or blinds
