Optimum Picture Quality and
Afterimage Burn-in Prevention
Optimum Picture Quality
-
To enjoy the optimum picture quality, go to the Control Panel in Windows Mode and adjust
the resolution and refresh rate as shown below. The picture quality of TFT-LCDs may
degrade if the optimum resolution is not selected.

- Due to the nature of the manufacturing of this product, approximately 1 pixel per million
(1ppm) may be brighter or darker on the LCD panel. This does not affect product
performance.
THE NUMBER OF SUB-PIXELS BY LCD PANEL TYPE
6,220,800
-
Unlike CDT monitors, TFT-LCD monitors (due to the nature of the panel) can be set to
only one resolution to obtain the optimum picture quality. Therefore, setting a resolution
other than the specified resolution may degrade the picture quality. To avoid this, it is
recommended that you select the optimum resolution specified for your monitor.
-
Light leakage could be on the edge of *SIP panel caused by functionality of SIP Panel, but it
does not affect performance of the product. (*SIP : Sensor in Pixel)
-
It is likely to be seen at low contrast and black screen. To minimize the effect of light
leakage, it is recommended to use a color higher than 20-grey contrast level for background
of the screen.
Prevention of Afterimage Burn-in
What is afterimage burn-in?
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.
