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.
