slot in your computer. For instructions on how to safely install your Matrox card,
“Hardware installation”, page 4
Problem
Using multiple displays under Windows 2000/XP/Vista, program
doesn’t work with your Matrox product
1
Cause
Your Matrox product 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 your Matrox product
unless it’s controlling your primary display.
Your computer BIOS (Basic Input/Output System) and the slot type (AGP, PCI, or PCIe –
“Choose an expansion slot for your interface card”, page 5
) of each graphics card and of your
interface card help determine which graphics hardware controls your primary display.
1
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 Matrox product to control your primary display, see the
other solutions.
2
Solution
Change the configuration of your computer BIOS so that the slot type of your interface card
has priority for controlling 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.
4
Solution
If you don’t need to use the graphics card 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.

Cause
The program you’re using may not work properly with systems using more than one display
at a time.
