3-1. Automatic screen adjustment
Options in MENU 1 (ADJUSTMENT) 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 automat-
ic 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 Monitor Settings Adjustment Disk (right
column).
2.
Press the MENU button.
The ADJUSTMENT Menu will be displayed.
3.
Press the    button.
The screen will become dark and [ADJUSTING] will be dis-
played. 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 On Screen Display
(OSD) Menu disappear. 
Notes:
·
In most cases automatic adjustment is sufficient.
·
If necessary due to any of the following, manual adjust-
ments (p. 17) can be performed after the automatic adjust-
ment.
·
When further fine adjustment is needed.
·
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 Adjust-
ment 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 on the
accompanying Monitor Settings Adjustment Disk.
This explanation is for Windows 95/98/Me/2000, and assumes that
the floppy disk drive is "A drive".
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 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 specifi-
cation of the input signal and is not a malfunction.)
3-2. Adjusting the backlight
The backlight brightness can be set to change automatically for use in
different surroundings. (Automatic brightness adjustment)
If the surroundings become brighter, the backlight will become
brighter.
If the surroundings become darker, the backlight will become darker.
The brightness sensor measures the brightness of the surrounding
environment. Never place anything in front of the brightness sensor.
Use the BRIGHT button to switch between automatic brightness ad-
justment or no automatic brightness adjustment.
Notes:
·
The OSD Menu automatically disappears several seconds
after the last command.
·
On the screen that appears after the values have been set,
the brightness can be further adjusted by pressing the
 and    buttons.
Adjusting the brightness
Carry out the commands without the On Screen Display (OSD) Menu
displayed. If the OSD Menu is displayed, press the MENU button
(several times may be required) and begin when the OSD Menu has
disappeared. 
When adjusting brightness automatically
Using the adjusted backlight brightness as a base, the brightness can
be adjusted automatically.
1.
Without the OSD Menu being displayed, press the   button or
the   button. The BRIGHT bar will appear at the bottom section
of the screen.
2.
Adjust by pressing the    button (darker) or the    button
(lighter).
Depending on the brightness of the surrounding environment,
the parameters for adjustment may be limited.
3.
Press the MENU button.
The OSD will disappear.
When not adjusting brightness automatically
1.
Without the OSD Menu being displayed, press the  button or the
button.
2.
Adjust by pressing the  button (darker) or the  button (lighter).
3.
Press the MENU button.
The OSD Menu will disappear.
Note: The OSD Menu automatically disappears several seconds af-
ter the last command.
