Information
For a 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.
• Resolution: 1920 x 1080
• Vertical frequency (refresh rate): 60 Hz
TFT-LCD panels manufactured by using advanced semiconductor tech-
nology 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 6,220,800.
When cleaning the monitor and the panel outside, please apply a small
amount of water to a soft cloth.Rub softly when cleaning the LCD area.If ex-
cessive 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 termination button is pressed. If there's still noise after
the automatic adjustment, use the Fine/Coarse adjustment function.
When viewing a fixed screen for an extended period of time, a residual
image or blurriness may appear. Change the mode to energy save or set a
screensaver to move the picture when you need to be away from the monitor
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 in-
creases 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.
