Matrox Graphics Card – User Guide
Problem
Not all graphics cards in the computer are fully supported
(Software doesn’t work with a certain graphics card, or another graphics card
doesn’t work at all)
1
Cause
If you have different models of graphics cards in your computer, your Matrox display driver
may not support all the graphics cards in your computer.
Under Windows 98/2000, a display driver may support one or more graphics cards. If a
display driver doesn’t support a certain card, a different display driver must be used for that
card. Software that depends on a certain display driver may not work with a graphics card
that’s not using the same display driver.
Under Windows NT 4.0, only one display driver at a time may be used. To use more than one
graphics card, the display driver must support all the graphics cards installed. If an
unsupported graphics card is installed in your computer, that card either isn’t used or your
computer restarts in VGA mode (single-display, 640 × 480 resolution, 16 colors).
1
Solution
Install the latest unified display driver for your Matrox graphics cards. (A unified display
driver supports more than one model of graphics card.) This driver is available on the Matrox
Web site (
www.matrox.com/mga
). Make sure that the display driver supports all Matrox
products in your computer. Install the display driver by running the setup program included
with it.
2
Solution
If a graphics card isn’t supported, you may need to remove it. If there’s a graphics processor
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 processor.
2
Cause
Windows 98/2000 – 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.

Note:
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
98/2000, you can use more than one display driver in this case.
