Matrox Electronic Systems LX G450, LE G450 manual Your monitor video controls may be improperly set

Note: Make sure your computer uses the other graphics card to control 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.)

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.

To control which graphics card is used for your primary display, you may be able to change the configuration of your computer BIOS. For information on how to change your computer BIOS settings, see your system manual.
