38 Matrox Extio Series – User Guide
Problem Using multiple displays under Windows 7/Vista/XP, program doesn’t
work with your Matrox product
1
Cause Your Matrox card may not be controlling your primary display. The graphics hardware that
controls your primary display is the one that first displays information when you restart your
computer.
A program that doesn’t recognize multiple displays may not work with graphics hardware
unless it’s controlling your primary display.
Your computer BIOS (Basic Input/Output System) and the slot type (PCI™ or PCIe – see
“Choose an expansion slot”, page 9) of each graphics hardware help determine which
graphics hardware controls your primary display.

Solution If you’re having problems with a program that can be moved on your Windows desktop, run
this program on your primary display. Make sure the program window doesn’t overlap any
other display. If the program doesn’t work with the graphics hardware controlling your
primary display, or you want your main graphics hardware to control your primary display,
see the other solutions.

Solution Change the configuration of your computer BIOS so that the slot type of your main graphics
hardware has priority for becoming the primary display. For information on how to change
your computer BIOS settings, see your system manual.
If your computer BIOS doesn’t let you select which slot type has priority for becoming the
primary display, a BIOS update may be available to let you do this. (The BIOS of most
computers can be updated with software.) For a possible BIOS update for your computer,
contact your system vendor.

Solution If there’s a graphics controller built into the motherboard of your computer, by changing
your computer BIOS settings, you may be able to change which device controls your primary
display. For more information, see your system manual.
5
Solution If you don’t need to use the graphics hardware that’s controlling your primary display,
remove it from your computer. If your primary display is controlled by the motherboard of
your computer, see your system manual for information on how to disable this graphics
controller.
