Ubuntu Desktop Video / Mini Monitor HD

I am having issues getting Ubuntu 22.04 to see my Mini Monitor HD cards. The system sees the PCI cards but when accessing the desktop video application it reports no devices installed.

I have Desktop Video 12.4.1 installed on my system.

Thoughts?

I am having a similar problem. I posted my notes here:

While I got it working by doing a fresh install of Ubuntu, it stopped working after a few days!

Did you get your working?
