I posted this on the apple pages, as it relates, but figured I would cross post here.

I am trying to use macs running HDMI into an "older" ATEM (ATEM production studio 4K). For those that don't know, older ATEM models have a limitation that it will only display inputs that match, exactly, the standard that is set in ATEM settings (gear icon, general tab, video). So 1080p inputs will not display if ATEM is set to 1080i (or any other combination)
I tested with 4 mac models and got a whole host of variations. Most interesting thing, even when Mac external display is set to "1920x1080" output resolution (as measured via pass thru with a decimator), is still 2160p at 24,25,30MHz.
I don't fully understand this, but my guess is that, if the Mac video card detects it CAN output a 2160 signal, it does, then modifies the screen to appear as a 1080 size. This is also an issue for the ATEM or other monitors that can accept 4K, but you don't want them to. (does anyone know the real answer?)
Solution: I converted my ATEM to 1080p 50. It was the only standard that would support all my MAC machines. Thankfully, my windows machines, and my PTZ cams can all output that standard.
I tried using SwitchResX on MACs before I went down this path and could not get it to output any other signals. All the settings I wanted were greyed out. It was the trial version, but it claimed to be fully functional for some time.
BMD and Decimator converters will solve these issues, but it would be great if you didn't have to buy more gear. And as of this writing, its all on backorder anyway :0
Also, yes I am aware of all the new BMD toys that solve these headaches, but I had a pile of (barely old) gear, and now its a fully functional production setup.
full test results below for the very technical, these are things that worked with the 4K 2 ME switcher.
-------------------------
PTZ cams – 1080i 59.94 (default)
1080p:25, 29.97, 50, 59.94.
1080i: 50, 59.94
Win laptop old – HP Zbook studio G4 – intel i5-7440hQ @2.80ghz – win 10 pro 22H2, build 19045.2846
works with most resolutions (via advanced display tab)
4K: 23.98, 24, 25, 29.97
1080i: 59.94, 50
1080p: 50, 59.94
Wont work: 1080i 60
1080p output shows up as 2160p in decimator for 23.98, 24, 25, 29.97, 30)
Mac laptop new - macbook pro 16" 2019 - 2.3ghz intel i9 - 8 core - montery 12.5.1
2160p: 24, 25, 30
1080x: Native NONE - output shows up as 2160p in decimator for 24, 25, 30)
If ran through HDMI--> sdi converter and “forced to hd”: 1080p: 24, 25, 30, 50, 60
Mac laptop old – mac Mojave (13” mid 2012) 2.5ghz i5. 4gb 1600 DDR3
1080p: 24, 25 (not 50)
1080i: 50
Mac mini new – montery 12.3.1 – Mac mini (M1 2020), Apple M1 chip, 16gb ram
2160p: 24, 25 (also outputs 30, 50,60 but ATEM 4K does not support)
1080x: NONE - output shows up as 2160p in decimator for 24, 25, 30)
Mac mini old – montery 12.6.5 – mac mini (late 2014). 2.6ghz dual core intel i5. 8gb memory, DDR3 1600
2160p: 24, 25
1080p: 24, 25, 50
1080i: none that I can find
1920x1080 setting in display properties, displays at 1920x1080 pixels but pushes 2160p to switcher (ie, it sends a 2160 signal and doubles the size of items on screen, or something similar)
