I have successfully had GTX 970 GPU's passed through but when I am now trying to get a Asus GTX 980 to pass through on a Win10 guest and i have a blank screen. GTX 980 works fine without unraid VM (tested with Windows 10 Install)

 

I am not sure what to do at this point. Does anyone have a fix for this?

 

here is my current xml
