Hello!
We have a client who has an existing system comprising of various sources including a Mac Mini feeding into an ATEM TVStudio, the output of which is used both for Live Stream and for monitors in the venue including a LED Wall.
The whole system is running on 1080i 50hz and has been operating without issue for a while. However the Mac Mini has been upgraded to the new Apple Silicon hardware, and we're now struggling to output 1080i 50Hz natively from the Mac.
The setting for 1080i no longer shows 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 have tried the "Alt Click" trick to show all resolutions however the options for '1080i, 1080p' etc are not there, only '1920 x 1080' type resolution options.
I have experimented including using an Intel MacBook Pro, running the same version of the OS which works, and tried a different M1 Mac Mini, TVS and HDMI cables, to rule out any hardware issues but it seems like the M1 Macs are unable to output an interlaced video signal.
The more research I do the more it seems like is a hardware limitation with the new M1 Graphics System and I can't find any instructions or advice on loading a custom EDID to try and "force" it.
Worst Case Scenario we can provide a scaler to resolve the issue but I want to make sure this definitely requires additional hardware before we head down that path.
Has anyone else experienced this issue or came up with a solution/work around that doesn't require a Scaler Inline?
Thank you in advance for your help and advice! - Fingers crossed this is me unable to see the wood for the tree's and not a permanent limitation of the M1 Hardware!
Andy!
