I'm trying to enable my GPU to be passed through to a Windows VM. Originally I was told that it wasn't able. After enabling VT-d in my bios, it now says "Disabled" instead of "Not Available". As the GTX 750 Ti is the only graphics device installed (no onboard graphics), it's defaulting as the display device and ESXi uses it to display it's screen. Is that the reason that it's greyed out? If I were to buy another graphics card and insert it as the default graphics unit, would the option to toggle it as a passthrough device then work?
Here is a picture of what I see currently:
Thanks for any help!
