Tried everything for months, always got black screens after some time with more then 2 vms running (gtx 780). The solution for me was to use virtu mvp with virtual vsync enabled. This tool enables to combine the integrated gpu and your geforce card. Problem is, your board has to support igpu and you have to enable it in bios. Also very driver sensitive. Make sure to use the latest version from virtu. There's a 30 day trial version available.
