AUTOMATIC SCREEN ADJUSTMENT
Options in MENU 1 (ADJUSTMENT) can be adjusted automatically
(CLOCK, PHASE, H-POS, V-POS).
Note:
• When setting up the monitor or a connected computer for the
first time, connecting an additional computer or after having
changed an aspect of the current system, perform an auto-
matic screen adjustment before use.
 Automatic adjustment screen display
To perform an automatic adjustment, first display an image that makes
the entire screen very bright. If you are using Windows, you can also
use the Adjustment Pattern on the accompanying Monitor Settings
Adjustment Disk for Windows.
Displaying the Adjustment Pattern (for Windows)
This explanation is for Windows 95/98/2000, and assumes that the
floppy disk drive is [A drive].
Note:
• 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".
1.  Place the Monitor Settings Adjustment Disk (provided) into the
computer's A drive.
2.  Open [My Computer] and select [3 Floppy (A:)]. If using Windows
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 adjustment, press the computer's [Esc]
key to exit the Adjustment Program.
• 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 input signal
specification and is not a malfunction.)
 Adjusting the screen automatically
1.  Press the MENU button.
The ADJUSTMENT Menu will be displayed.
2. Press 
the 
d
 button.
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.)
3.  Press the MENU button 4 times to make the On Screen Display
(OSD) Menu disappear.
Notes: • In most cases the monitor is ready to be used after auto-
matic adjustment.
•  If necessary due to any of the following, manual adjustments
(p. 19) can be made 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, after command 2 above, [OUT OF ADJUST] is dis-
played. (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.)
ADJUSTING THE BACKLIGHT
The backlight brightness can be adjusted.
Carry out the commands without the On Screen Display (OSD) Menu
displayed. If the OSD Menu is displayed, press the MENU button (sev-
eral times may be required) and begin when the OSD Menu has disap-
peared.
1.  Without the OSD Menu being displayed, push the 
e
 or the 
d
 but-
ton. At the bottom of the screen the BRIGHT bar will appear.
2.  Adjust by pressing the 
e
 button (darker) or 
d
 button (lighter).
The BRIGHT bar automatically disappears approximately 3 seconds
after the last command.

tor Settings Adjustment Disk for Windows can be used.
If using a computer other than Windows, the adjustment pattern can-
not be used. Display an image that makes the entire screen very
bright, and adjust while watching the screen.
