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 an expansion slot”, page 5) of each graphics card help determine which graphics card controls your primary display. 1Solution 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. Change the configuration of your computer BIOS so that the slot type of your main graphics card has priority for becoming the primary display. For information on how to change your computer BIOS settings, see your system manual. If your computer BIOS doesn’t let you select which slot type has priority for becoming the primary display, a BIOS update may be available to let you do this.
