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.

4.3. OSD MENU Adjustments and Settings Screen Adjustment
Screen adjustments for the monitor should be used in suppressing screen flickering and
also for adjusting the screen to its proper position. There is only one correct position for
each display mode. It is also recommended to use the OSD Menu function when first
installing the display or whenever changing the system.
Note: Allow the monitor to stabilize for at least 20 minutes before making image
adjustments.
Making adjustment must be VGA signal.
Adjustment Procedure
1. Adjust by <Auto Adjust> menu in the OSD Menu.
To automatically adjust the clock, phase, screen position and resolution.
Note:
The Auto sizing function is intended for use on the computer running Windows. It may
not work properly when the computer is running on MS-DOS (Not windows) or the
background color for the "wall paper" or "desktop" pattern is set to black.
If the appropriate screen cannot be made by using the Auto adjustment button, adjust
the screen through the following procedures.
2. Adjust by using <VGA> menu in the OSD Menu.
(1) Vertical bars appear on the screen
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 the
Right and Left buttons.
Note: Horizontal bars may not completely disappear from the screen depending on the
computer.
(3) The screen position is incorrect.
Use the <→H-Position> or <V-Position> adjustment.
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
adjustment procedure. (Clock Phase <→→H-Position> or <V-Position>)

5. TROUBLESHOOTING
If a problem persists even after applying the suggested remedies, contact a dealer.
Problems Points to check with Possible Solutions
1. No picture
Indicator status: Off Check that the power cord is correctly connected. If the
problem persists, turn off the monitor power for a few
minutes, then turn it back on and try again.
- when the signal is not inputted correctly, even if the
monitor functions properly.
- When the image is displayed correctly after a short time,
there is no problem with the monitor. (Some PCs do not
output the signal soon after powering on.)
Check that the signal cable is properly connected to the PC
or graphics board.
Indicator status: Green Check the "Brightness" setting.
2. Display position
is incorrect.
3.Vertical bars of
distortion appear.
4.Horizontal bars of
distortion appear.
Adjust the image position or decrease the horizontal or
vertical bars using the <Auto Adjust> menu. If the
problem persists, use the graphics board's utility software
to change the display position if available.
5. The screen is too
bright or too dark. Adjust the <Brightness> (The backlight of the LCD
monitor has a fixed life span. When the screen becomes
dark or begins to flicker, please contact your dealer.)
6. Afterimages appear. - Use the screen saver or timer when displaying the same
image for extended periods of time.
- Afterimages are particular to LCD monitors. Avoid
displaying the same image for extended periods of time.
7.The screen has
defective pixels
(e.g. slightly light
or dark).
This is due to the characteristics of the panel itself, and not
the LCD product.

6. CLEANING
Periodic cleaning is recommended to keep the monitor looking new and to prolong its
operation lifetime.
Note: Never use thinner, benzene, alcohol (ethanol, methanol, or isopropyl alcohol),
abrasive cleaners, or other strong solvents, as these may cause damage to the cabinet
or LCD panel.
Cabinet
To remove stains, wipe the cabinet with a soft, lightly moistened cloth using a mild
detergent. Do not spray wax or cleaner directly into the cabinet. (For details, refer to
the manual of the PC.)
LCD Panel
The LCD surface can be cleaned with a soft cloth, such as cotton or lens paper.
If necessary, stubborn stains can be removed by moistening part of a cloth with water
to enhance its cleaning power.
