Analog monitors only –
The Matrox display driver may be trying to use settings your
monitor doesn’t support. This can happen if a monitor was never selected in the software and
the display resolution was changed to one your monitor doesn’t support, or if the monitor
connected to your computer was changed without it being changed in the software. One of
your monitors may not support the monitor settings of the main monitor.
