For Better Display
Adjust the computer resolution and screen injection rate (refresh rate) on the computer
as described below to enjoy the best picture quality. You can have an uneven picture quality
on screen if the best picture quality is not provided for TFT-LCD.

Vertical frequency (refresh rate): 60 Hz
TFT-LCD panels manufactured by using advanced semiconductor technology with a
precision of 1ppm (one millionth) and above is used for this product. But the pixels of RED,
GREEN, BLUE and WHITE color seem to be bright sometimes or some of black pixels
could be seen. This is not from bad quality and you can use it without any problems.
For example, the number of TFT-LCD sub pixels contained in this product are 3,133,440
(6,220,800).
When cleaning the LCD Display and the panel outside, please apply the recommended
small amount of cleaner by using a soft cloth to polish. Do not force the LCD area but rub
softly. If excessive force is applied, you may stain it.
If you are not satisfied with the picture quality, you can get better quality of picture by
performing the "Auto Adjustment function" in display screen that is appeared as window

riness may appear. Change the mode to energy save or set a screensaver to move the picture
when you need to be away from the LCD Display for an extended period of time.
PRODUCT INFORMATION (Image Retention Free)
What is Image Retention ?
Image retention may not occur when a LCD panel is operated under normal conditions.
Normal conditions are defined as continuously changing video patterns. When the LCD
panel is operated for a long time with a fixed pattern (over 12 hours), there may be slight
difference in voltage between electrodes that work the liquid crystal (LC) in a pixel. The
voltage difference between electrodes increases with time, forcing the liquid crystal to lean.
When this occurs, the previous image may be seen when the pattern is changed. To prevent
this, the accumulated voltage difference must be decreased.
