22 Matrox Graphics Card – Installation Guide
Troubleshooting
This section contains solutions to problems you may encounter with your Matrox graphics card.
Problem: Computer doesn’t boot after Matrox card is installed
Cause – Some computers may not properly detect the addition or change of an internal PCI
card. On startup, a computer may beep differently from normal to indicate this error.
Solution – Reset your computer’s CMOS. This is usually done through a switch or jumper
on the motherboard of your computer. Check your system manual or contact your computer
vendor for instructions on how to do this.
Cause – There may be another graphics adapter in your computer. (For MGA multi-display
mode in Windows NT, all other graphics cards in your computer must also be Matrox cards of
the same type – Millennium, Millennium II or Mystique 220.)
Solution – If another graphics card is plugged into an expansion slot, remove it.
Solution – If a graphics adapter is built-in to your computer’s motherboard, your system
may have not automatically disabled it when you inserted your Matrox card. Check your
system manual for instructions on how to disable your computer’s built-in graphics adapter.
Problem: Wrong color balance, screen image off-center, or no picture at all
Cause – Your monitor’s video controls may be improperly set.
Solution – Adjust your monitor’s controls (brightness, contrast and so on). For more
information, see your monitor manual.
Cause – The monitor connections may have been inserted improperly.
Solution – Make sure the monitor’s power cable is firmly in place.
Solution – Make sure the 15-pin connector (see picture) to your Matrox
graphics card is firmly in place.
Solution – If your monitor uses a 15-pin connector, make sure the
connection to the monitor is firmly in place.
