Burn-in
Cleaner
(PD3420Q)
Screen burn-in or image retention may be found on the
screen if a still image is displayed for an extended period of
time. Enable this function to help reduce the visible fixed lines
or shades on the screen by showing several default patterns.
Once enabled, to disable this function, press any of the control keys.
Screen burn-in occurs due to panel limitation and should not be
considered as a manufacturing defect. To avoid screen burn-in, do
not play a still image for an extended period of time in the first
place. Use your computer's power management function.
