Solution
If a graphics card isn’t supported, you may need to remove it. If there’s graphics hardware
built into the motherboard of your computer that’s not supported by your software, see your
system manual for information on how to disable this graphics hardware.
2
Cause
Windows 2000/XP
– If the Windows method for display driver installation was used (instead
of running the setup program included with your Matrox display driver), the driver may not
be installed for all the graphics cards it supports.
1
Solution
Run the setup program included with the Matrox display driver. The setup program
automatically installs the display driver for each Matrox graphics card it supports.
Problem In multi-display mode, displays aren’t numbered consecutively
1
Cause
If you have more than one graphics card in your computer, the
display numbering may not be consecutive for the displays of a
multiple-display card (for example, a DualHead supporting
card). Display numbering depends on the types of expansion
slots used in your computer (AGP and PCI) and the BIOS settings of your computer.

A unified Matrox display driver may not be available for all the models of Matrox
graphics cards installed in your computer (especially for older models). Under Windows
2000/XP, you can use more than one display driver in this case.
Note:
In multi-display mode, you may have limited control over the arrangement of
your displays. For more information, see Matrox PowerDesk documentation.
