Can you give us some more detail about what you're trying to accomplish? I run dual monitors at work and at home. Your system specs would also be most helpful

Keep us posted

Yes i suppose i was not very clear, I am using an AMD APU along with an AMD GPU. I am attempting to enable Dual graphics (also known as Crossfire graphics) but i cannot find the option in the AMD catalyst control center. I am using a Gigabyte f2a88xm-d3h motherboard. If you need any other specific info please let me know, im not sure what would help you to solve my problem.

Which AMD APU and which GPU?  I understand they are quite selective about which combo's work and what don't.

GPU: AMD R7 250

 

APU: A10 6800K

 

That sure would be dissapointing if I built with a incompatible combo.

The situation is not exactly clear to me anyway. Both AMD's web site and a third party website recommend the HD6570 and HD6670 for dual graphics support with that APU, while saying the R7-250 can be dualled with A10-7xxx series APU's.  The FAQ gives some more information about how to enable it in the Catalyst software.  It doesn't mention BIOS settings but I'd imagine if there is no specific setting for enabling dual graphics in BIOS, then just ensuring that the APU graphics are enabled should be enough (if the combo is indeed compatible).

 

The R7-250 is more powerful than the on chip HD 8670D, so if it's not possible to enable it, then just using that would probably be the best thing to do.
