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

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. (The BIOS of most
computers can be updated with software.) For a possible BIOS update for your computer,
contact your system vendor.
