Problem Not all graphics cards in the computer are fully supported
(Software doesn’t work with a certain graphics card, or another
graphics card doesn’t work at all)
1
Cause
If you have different models of graphics cards in your computer, your Matrox display driver
may not support all the graphics cards in your computer.
Under Windows 2000/XP, a display driver may support one or more graphics cards. If a
display driver doesn’t support a certain card, a different display driver must be used for that
card. Software that depends on a certain display driver may not work with a graphics card
that’s not using the same display driver.
Under Windows NT 4.0, only one display driver at a time may be used. To use more than one
graphics card, the display driver must support all the graphics cards installed. If an
unsupported graphics card is installed in your computer, that card either isn’t used or your
computer restarts in VGA mode (single-display, 640 × 480 resolution, 16 colors).
Note:
Your primary display can’t be disabled.
Note:
To restore display adapters, repeat steps 2–5, but click
Enable
in step 4.
