Mac OS 12.3 Beta Video Monitor Issue

[bwcw]

I am running Mac OS 12.3 Beta on my 2018 Mac Mini Intel Version and am having extreme problems connecting via HDMI to my Sony 65" TV. The resolution I was using on Mac OS 12.2 was 1920x1080. This has only happened with 12.3. I can see my Mac Mini when running VNC on my MacBook Pro. Also, If I reboot my Mac Mini, it starts off showing on my TV Mac Mini but freezes about a third of the way through startup on the screen, I know startup continues on the Mac Mini because after a few minutes, I connect via VNC on my MacBook and I can see the Mac Mini screen on my MacBook. For some reason, it will not show on the TV. I have tried unplugging my HDMI cable and reconnecting by no deal. This is definitely a software problem. Has anyone experienced this yet?

I'm having the same issue with my mini, and I know it not my HDMI port bc my mini also has windows partition on it and that works just fine.

I ended up getting a USB C to HDMI cable running off the thunderbolt ports and it works fine now.
