1
Cause Your monitor may not be detected by the software.
1
Solution Restart your computer. If your monitor is a Plug-and-Play (DDC) monitor, it should be
automatically detected by the software.
Problem Built-in network hardware doesn’t work after graphics card is
installed
1
Cause The installation of a graphics card may have caused your computer to reallocate system
resources.
1
Solution Try reinstalling your network drivers.
2
Solution Try moving your Matrox graphics card to another PCIe slot in your computer. For
instructions on how to safely install your Matrox card, see “Installing your graphics
hardware”, page 6.
Problem Using multiple displays under Windows 7 program doesn’t work with
your Matrox product
1
Cause Your main graphics card may not be controlling your primary display. The graphics card 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 a graphics card 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 7) of each graphics card help determine which graphics
card 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 card controlling your primary
display, or you want your main graphics card 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 main graphics
card 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.
