Troubleshooting
What to do if you have a problem
If you experience problems with your Matrox product:
 Make sure your Matrox card is properly installed, you’re using the correct connectors,
and that all connectors are properly fastened. For more information, see “Installing your
graphics hardware”, page 9 and “Connecting your monitors”, page 14.
 Review the documentation provided with your Matrox product, including the
information in this section, to see if your problem is already addressed.
 If graphics hardware is built into your computer motherboard, make sure you disable
your computer’s built-in graphics hardware. Also, remove any currently installed display
drivers for that graphics hardware.
If your problem persists, contact Matrox. For more information, see “Customer support”, page 31.
