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/Vista, you can use different display drivers for different products.
Software that depends on a specific display driver feature may not work if your graphics
hardware is using different display drivers.
Note:
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.
2
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/Vista – 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.
3
Cause
Windows Vista/Server 2008 – You may be using a WDDM (Windows Vista Display Driver
Model) display driver that doesn't support all graphics hardware in your computer. For
more information, see the Microsoft Web site.
1
Solution
Make sure you're using a WDDM display driver that supports all the graphics hardware
installed on your system.
