Problem Using multiple displays under Windows 98/Me/2000/XP or NT 4.0, program doesn’t work with main graphics card

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 DualHead-supporting graphics card may display this startup information on both of its displays at the same time.)

Programs that don’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 an expansion slot”, page 3) of each graphics card help determine which graphics card controls your primary display.
