Problem Using multiple displays under Windows 2000/XP or NT 4.0,
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 (ISA, PCI or AGP – see
“Choose a PCI slot”, page 4) of each graphics card help determine which graphics card
controls your primary display.
