Information
Adjust computer resolution and screen injection rate (refresh rate) on computer as described below to
enjoy the best quality of picture. You can have an uneven quality of picture in the screen if the best quality
of picture is not provided in TFT-LCD.
• Resolution: 1360 x 768
• Vertical frequency (refresh rate): 60 Hz
TFT LCD panels manufactured by using advanced semiconductor technology with precision of 1ppm (one
millionth) above are used for this product. But the pixels of RED, GREEN, BLUE and WHITE color appear
to be bright sometimes or some black pixels may be seen. This is not from bad quality and you can use it
without any problelms.
• For example, the number of TFT LCD sub pixels contained in this product are 3,133,440
When you clean the LCD Display and the panel outside, please apply the recommended small amount of
cleaner by using soft and dry cloth and polish it. Let LCD area not to be forced but to be scrubbed out
softly.

What is Image Retention ?
Image retention may not occur when a LCD panel is operating 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.
