Hi,
coming from this thread I opened an own issue as @dcsapak suggested.
I have issues with the video output when passing through the latest Blackwell Generation RTX Pro 6000 Max Q Version. The GPU passthrough works fine, the GPU is detected in Windows and Ubuntu Server. In Windows 11 there is no Code 43, I use the latest 580 driver from Nvidia Website. In the Nvidia Manager on the Windows VM the GPU is also available and shows the name of my Display but there is no video output, the screen is just black (but backlight is own, so their is a signal).
Same goes for ubuntu server 24.04 version. The GPU is recognized with the latest Nvidia driver from there website (I downloaded and run the abc.run file from nvidia site and selected the MIT Version of the driver, proprietary is not working for that gpu). Here are some outputs:
System is Proxmox 9.0.6 with zfs install:
