What is afterimage burn-in?
Afterimage burn-in should not occur when the LCD panel is operating normally. Normal operation
refers to a continuously changing video pattern. If the LCD panel displays a fixed pattern for an
extended period of time (more than 12 hours), a slight voltage difference may occur between the
electrodes in pixels that control the liquid crystals.
Such a voltage difference between electrodes increases with time and makes the liquid crystals thinner.
When this occurs, a previous image can remain on the screen when the pattern changes. To prevent
this, the accumulated voltage difference should be reduced.

The best way to protect the product from afterimage burn-in is switching the power off or setting
the PC or system to run a screen saver when not in use. Also, Warranty service may be limited
depending on instruction guide.
