Problem Using multiple displays under Windows 2000/XP, program doesn’t
work with main graphics card
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 (AGP, PCI, or PCIe – see
“Choose a PCI slot”, page 5) 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.
