SOLVED: The issue appears to be with using an HDMI cable on the VM. I got my DisplayPort to HDMI cable out and converted one of the DisplayPort slots on the 1080 Ti to HDMI on my monitor and we are good to go. I do wonder if passing through HDMI audio from the GPU means you can't use the HDMI output due to the HDMI audio being on the same IOMMU group as the GPU. Not sure, but it works now.

Update to this: In Windows (via RDP), I can see that the HDMI port of the video card is connected, still no video display though. Also tried dumping the BIOS of my graphics card directly from unraid as unraid is using the onboard video for output but still no video.

Hi all, Sorry for yet another pass through but I've exhausted my Google-fu to no avail. Hardware: 2 x E5-2670 v2 Gigabyte GA-7PESH2 16 x 8GB (128GB total) DDR3 ECC memory Zotac Blower GTX 1080 Ti Common steps: * Downloaded Zotac vBios from TechPowerup, used hex editor to remove the header from the vBios. What I've tried: *** SeaBios w/i440fx-3.1 -- I get display from the 1080 Ti when using the Microsoft generic driver. As soon as Microsoft or I install nVidia drivers and reboot, screen is black and stays black. When I reboot the VM, I can see the windows splash screen with the spinning circle of dots, then when it goes into the login/desktop, screen is black and eventually goes to "no signal" on my monitor. ** OVMF w/q35-3.1 -- No display from 1080 Ti, even with Microsoft generic driver. ** OVMF w/i440fx-3.1 -- No display from 1080 Ti, even with Microsoft generic driver. Commonalities between three setups: * All three VMs are RDP-able and I can verify that there are no issues with the 1080 Ti (if I use non-patched vBios, I get error code 43). * I'm using HDMI to connect to the monitor. Given that video works with the SeaBios/i440fx-3.1 setup, I don't think it's a port issue. Has anyone run into this/been able to resolve something like this? I appreciate any and all insights. Thanks! EDIT (Solution): For me, changing from HDMI to displayport on the GPU solved the issue. Not sure if IOMMU grouping of GPU and HDMI audio together means that HDMI port can't be used on GPU but VM is happily outputting to my monitor now.
