Hello,

New to unRAID and servers in general.  Can't seem to separate an IOMMU Grouping with my Graphics Card in it. Tried all the techniques described in this video.

No but I moved it

Please turn on acs override and set to option: both. See if that helps. 

Didn't most of the 20 series cards have an USB type C connector for VR onboard? All what i can see in your group 15 are NVIDIA stuff. Good luck splitting this up. You have to passthrough them all to your VM i guess is the way to go. 

Ok got past the error.  But now I can't figure out how to get to the windows 10 install tried display port and hdmi from motherboard.  Just black screen.  Tried to use a vnc from a mac and it says rejects connection.  Thanks
