So, it appears to not be a cable-related issue, the reason I've identified this is because when I swap the cable input to be in the top HDMI output (and not the bottom), the video works fine.
I've also done the following troubleshooting:
- Tried different cables
- Tried brand new cables
- Tried same length cables
- Tried a fully different Macbook that isn't M1
- Tried clean uninstall and reinstall
- Tried downgrading to stable non-beta version
The only thing that I'm weary of is that both displays worked fine for about a day, before the non-functioning HDMI outlet started blacking out intermittently to the point now, where the display doesn't detect any signal.
