3M Touch Systems Proprietary Information
Horizontal And Vertical Position
The position of the displayed image can be adjusted if necessary by
altering these two settings.
Clock Setting
If the Clock setting of your image is not
fine-tuned, you may observe periodic
vertical bars of video noise. These bars
of noise are usually adjusted out when
an Auto Adjust is performed. If the bars
of noise are still present, this setting can
be adjusted manually.
Adjust this setting so that the vertical bars of noise are replaced by
either an even amount of noise across the whole screen, or the noise
disappears completely. Adjusting the Phase Setting can eliminate
any remaining noise.
Phase Setting
If you do an Auto Adjust, the monitor
will try to find the best Phase setting. If
the phase of your monitor is not fine-
tuned, you may observe unstable
horizontal noise lines and cross talking,
stretching from the edge of small
windows on your display. Adjusting the
Phase setting can eliminate this noise.
