Optimum Picture Quality and Afterimage

Burn-in Prevention

Optimum Picture Quality

•

Due to the nature of the manufacturing of this product, approximately 1 pixel per million (1ppm)

may be brighter or darker on the panel. This does not affect product performance.

The number of sub-pixels by panel type: 6,220,800

•

Run Auto Adjustment to improve the picture quality. If noise is still found even after auto

adjustment, adjust Coarse or Fine.

•

Leaving the screen fixed on a stationary image for an extended period of time may cause afterimage

burn-in or defective pixels.

Activate power-saving mode or a dynamic screen saver if you will not be using the product for

an extended period of time.

Prevention of Afterimage Burn-in

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.
