Original Question:
Hi all,
Can anyone confirm if it is possible to use both my integrated GPU (HD4600) and a GT710 simultaneously so I can drive multiple displays? I currently have two displays connected to my iGPU and would like to use the card to drive a third display.
I had a quick google but couldn't find anything on this.
Running Big Sur currently.
Thanks.
