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.
Note: If you identify a program that doesn’t work well with Matrox acceleration, please
contact Matrox technical support (see page 26) and describe the problem. This
information may help us come up with a fix or work-around in a future driver release.
