All I know is that you have to jump through hoops to make an nvidia card work with pass-through, most likely you will need to have a monitor connected directly to it. The reason being that Nvidia’s drivers don’t allow the card to work without a physical output connection active, they restrict this kind of usage for their professional cards like Quadro which cost a fortune for mostly the same chips with a bit more memory and other bells and whistles. Not that the cards wouldn’t be able to handle it, it’s all in the drivers.
