USB to HDMI Adapter Passthrough for Windows 11 VM – Anyone Tried This?

[moshoarian]

Hi everyone,

I'm running a Windows 11 VM on Proxmox and need direct HDMI output. My iGPU passthrough is not an option, so I’m considering passing through a USB to HDMI adapter (StarTech USB 3.0 to Dual HDMI) and using it as a display output.

My Question:
Has anyone successfully used a USB to HDMI adapter for display output in a Proxmox VM?

Does Windows 11 detect the adapter properly after USB passthrough?
Is there any noticeable lag or performance issues?
Any specific USB passthrough settings needed for DisplayLink-based adapters?
I've attached a photo of the adapter I'm considering. Any advice or experience would be greatly appreciated!

Thanks in advance!

Although I have done this with a USB sound adapter, never video.
Why do you need to see the VM's screen on a physical monitor anyways?

Thank you for your response. I want to use Windows 11 VM as my main desktop.

might be better off with one of these since you need the other peripherals to work also, but you would need type C port on the host

Thank you for your response. I have Gigabyte H610i and it doesn't have type C port. Guessing, Docker Station is best option for me. Thanks again!
