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.
1
Solution
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.
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.
Note:
Your primary display can’t be disabled.
