2.Run the "Screen Adjustment Program".
Having read the "Readme.txt" file, run the "Screen Adjustment Program" in the
enclosed EIZO LCD Utility Disk. Step by step, adjustment is provided by the wizard
guide. (If using the Windows, the program can be directly run from the menu screen of
the CD-ROM.)
* If the user's operating system has no utility disk (e.g. OS/2), we recommend
setting the desktop pattern to that as shown in the diagram on the following.
3.Adjust by using menu in the ScreenManager.
(1) Vertical bars appear on the screen
=> Use the < Clock > adjustment.
Select the and eliminate the vertical bars by using the Right and Left of
the Directing switches.
Do not continuously touch the Directing switches, as the adjustment value will
change quickly and make it difficult to locate the most suitable adjustment point.
If the horizontal flickering, blur or bars appear, proceed to adjustment
as follows.
