Outputs from M1 MacMini

I have got the Mini connected to a display via HDMI direct out of the back, works fine.

I'm trying to run a USBc feed out of the back to a LG TV and can't get a signal. Nothing is showing up in FCPX when trying to output.
I've tried with a USBc to Thunderbolt connector to a BM UltraStudio doesn't work.

Any ideas?

Hi Marc, please help me understand a bit better. As per my understanding you have connected a Monitor through HDMI on your M1 to HDMI on your monitor ?
Also you are trying to connect another screen (LG) through USB-C ?

Correct

Ok great, I might be able to help you with this as I had a similar issue recently.
So, in order to connect 2nd screen you can use either Dsiplay port or HDMI on your docking station and connect it to the LG tv.
Download Display Link drivers (Latest version works well). Go to System Preferences and enable 'Screen Recording'. Display Link is detected as 'Screen Recording' in Mac. After enabling this, it will detect your second monitor.
There is however another issue. Every time you will restart your MAC, You will have to unplug/plug your docking station to detect the second TV again. Hope this helps and let me know if any more questions.
