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 2000/XP, 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.

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 s i te (www.matrox.com/graphics
). 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.
Note:
Your primary display can’t be disabled.
Note:
To restore display adapters, repeat steps 2–5, but click
Enable
in step 4.
Note:
If your Matrox product was provided by the manufacturer of your computer, check
the Web site of that manufacturer for the latest display driver. A display driver provided by
the manufacturer of your computer is more likely to be tested with your computer model.
