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 Win-
dows.
Displaying the Adjustment Pattern (for Windows)
This explanation is for Windows 95/98/2000/Me, 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 
1
/
2
 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.
Note: 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 specifica-
tion and is not a malfunction.)
