LCD PANEL
When the monitor is cold and brought into a room or the room temperature goes up
quickly, dew condensation may occur inside and outside the monitor. In that case, do
not turn the monitor on and wait until dew condensation disappears, otherwise it may
cause some damages to it.
In order to suppress the luminosity change by long-term use and to maintain the stable
luminosity, please use the monitor with the lower brightness.
The screen may have defective pixels. These pixels may appear as slightly light or dark
area on the screen. This is due to the characteristics of the panel itself, and not the
product.
The backlight of the LCD panel has a fixed life span. When the screen becomes dark or
begins to flicker, please contact your dealer.
Do not press on the panel or edge of the frame strongly, as this may result in damage
to the screen. There will be prints left on the screen if the pressed image is dark or
black. If pressure is repeatedly applied to the screen, it may deteriorate or damage
your LCD panel. Leave the screen white to decrease the prints.
Do not scratch or press on the panel with any sharp objects, such as a pencil or pen as
this may result in damage to the panel. Do not attempt to brush with tissues as this
may scratch the LCD panel.
When the screen image is changed after displaying the same image for extended
periods of time, an afterimage may appear. Use the screen saver or timer to avoid
displaying the same image for extended periods of time.

background color for the "wall paper" or "desktop" pattern is set to black.
If the appropriate screen cannot be made by using the Auto adjust ment button, adjust
the screen through the following procedures.
2. Adjust by using <VGA> menu in the OSD Menu.

Use the <Clock> adjustment.→
Select the <Clock> and eliminate the vertical bars by using the UP and Down of the
Control buttons.
Do not continuously press the Control buttons, as the adjustment value will change
quickly and make it difficult to locate the most suitable adjustment point. If the
horizontal flickering, blur or bars appear, proceed to <Phase> adjustment as follows.
(2) Horizontal bars appear on the screen.
Use the <Phase> adjustment.→
Select the <Phase> and eliminate the horizontal flickering, blurring or bars by using th e
Right and Left buttons.
Note: Horizontal bars may not completely disappear from the screen depending on the

The <H-Position> or <V-Position> adjustment moves the image to the correct
position. Select <Position> and adjust the position by using the Up and Down buttons.
If vertical bars of distortion appear after finishing the <H-Position> or <V-Position>
adjustment, return to <Clock> adjustment and repeat the previously explained
