Apple Mac Mini M1 1080i resolution problem

Hi

I have just got the

Apple Mac Mini M1 and have encountered a severe problem. When I connect the Mac

Mini’s HDMI output as a display or a second monitor on my ATEM Television

Studio but I do not get a option ‘1080i’ or anything similar to it. The only

resolution options in 1920x1080. The setting for 1080i does not show up in the

Display Settings when the BMD HDMI is connected and the output from the Mac

Mini can be seen on test monitors as 1080p

I’ve tried many options

on it but without any progress (just shows a black screen). Our ATEM TVS whole

system is running on 1080i 50hz

Note: Our Intel Macbook Pro just works fine.

Can someone please help

us out with the issue.

Regards

Jenny!
