34 Matrox Mura MPX Series – User Guide
Problem After the startup screen, or after display settings are changed, the
screen image is garbled or unusable
(blank screen, rolling or overlapping screen images)
1
Cause Analog monitors only – The Matrox driver may be trying to use settings your monitor
doesn’t support. This can happen if the display resolution was changed to one your monitor
doesn’t support or if the monitor connected to your system was changed without changing
the display or monitor settings in the software.
1
Solution Make sure your monitor supports the display mode currently in use. After installing your
Matrox product, your system uses either the preferred display mode for your monitor or a
display mode of 800 × 600 at 60 Hz.
2
Solution If none of your monitors are available, reinstall your Matrox drivers. For more information
on reinstalling your driver, see the following solution.
