Support of DVI non-compliant image sources
A resolution higher than 1600 x 1200 pixels causes stripes within the image if, for
example, the screensaver of a Mac mini is displayed.
This affects the way the image is displayed on both the monitor of the computer
module as well as the monitor of the user module.
To improve the image signal of computers that provide a DVI signal which is not
DVI compliant, a special button is implemented in the setup menu. This button is
used to modify the PLL bandwidth.

system are not DVI compliant.
