When further fine adjustment is needed.
When [OUT OF ADJUST] is displayed. (When the screen
displays an entirely dark image, the automatic screen ad-
justment may be disabled. When making an automatic ad-
justment, 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 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
computers 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 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.)
3-2. Adjusting the backlight
