(WHEN USING AN ANALOG SIGNAL)
(1) AUTOMATIC SCREEN ADJUSTMENT
Options in the ADJUSTMENT Menu can be adjusted automatically
(CLOCK, PHASE, H-POS V-POS).
Note: When setting up this monitor for the first time or after having
changed an aspect of the current system ,perform an automatic
screen adjustment before use.
1.  First display an image that makes the entire screen very bright. If
you are using Windows, you can use the Adjustment Pattern on
the accompanying Utility Disk (right column).
2.  Press the MENU button.
The ADJUSTMENT Menu will be displayed.
3. Press 
the 
d

The screen will become dark and [ADJUSTING] will be displayed. 
After a few seconds the ADJUSTMENT Menu will return. (The
automatic adjustment is now complete.)
4.  Press the MENU button 4 times to make the OSD Menu disap-
pear.
Notes: •  In most cases automatic adjustment is sufficient.
•  If necessary due to any of the following, manual adjustments
can be performed after the automatic adjustment.
• When further fine adjustment is needed.
• When the computer's video input signals are Composite
Sync or Sync On Green. (Automatic adjustments may not
be possible.)
• When [OUT OF ADJUST] is displayed. (When the screen
displays an entirely dark image, the automatic screen
adjustment may be disabled. When making an automatic
adjustment, be sure to either use the Adjustment Pattern or
try displaying an image that makes the entire screen very
bright.)
Opening the Adjustment Pattern (for Windows)
If you are using Windows, you can use the Adjustment Pattern (for
Windows) on the accompanying Utility Disk.
This explanation is for Windows 95/98/Me/2000, and assumes that the
floppy disk drive is "A drive".
1.  Place the Utility Disk (provided) into the computer's A drive.
2.  Open [My Computer] and select [3 
1
/

 Floppy [A:]]. If using Win-
dows 3.1, open [File Manager] and choose "A drive".
3.  Double click on [Adj_uty.exe] to run the Adjustment Program. 
The Adjustment Pattern will appear.
Notes: •  After completing the adjustments, press the computer's [Esc]
key to exit the Adjustment Program.
•  If the floppy disk drive of your computer is not "A drive",
please read the below substituting the floppy disk drive you
are using in place of "A drive" or "A".
•  If your computer's display mode is set to 65K colors, you
may see the different color levels in each color pattern or the
gray scale may look colored. (This is due to the specification
of the input signal and is not a malfunction.)
(2) MANUAL SCREEN ADJUSTMENT
Adjustments can be made using On Screen Display (OSD) Menu pro-
vided.
1.  Display an image that makes the entire screen very bright. If using
Windows, you can open and use the Adjustment Pattern on the
accompanying Utility Disk.
2.  Press the MENU button.
The ADJUSTMENT Menu will be displayed.
At this point relevant menu options can be adjusted. Each time the
MENU button is pressed the next menu is selected. (ADJUST-
