Matrox Graphics Card – User Guide 31
Problem In multi-display mode, displays aren’t numbered consecutively
1
Cause
If you have more than one graphics card in your computer, the
display numbering may not be consecutive for the displays of a
multiple-display card (for example, a DualHead supporting
card). Display numbering depends on the types of expansion slots used in your computer
(AGP and PCI) and the BIOS settings of your computer.
