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.
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 Utility Disk
for Windows.
Displaying the Adjustment Pattern (for Windows)
This explanation is for Windows 95/98/2000/Me/XP,
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 Utility Disk (provided) into the
computer's A drive.
2. Open [My Computer] and select [3 ½ 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.

After completing the adjustment, press the
computer's [Esc] key to exit the Adjustment
Program.
Notes:
-
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.)
