Not surprising any longer... There's a whole class of Mac Mini's (including the latest revision) where if you install Catalina, the HDMI port dies.

  Ya I've seen those, that's completely crazy.

  As in, permanently breaks the hardware? Or just won't function with that software version?

    "For those that are going to revert back to Mojave as a solution, a number of people are noting that this does not fix the issue (it didn't for me), indicating there is perhaps some sort of firmware update taking place with Catalina that will not be rolled back when you install Mojave." — https://forums.macrumors.com/threads/catalina-causing-issues-with-hdmi.2205380/ https://forums.macrumors.com/threads/catalina-causing-issues...

    Rolling back worked for me, but the workaround is using the USB-C to HDMI dongle. (and I think I needed the dongle to downgrade.)
