- The flickering/tearing

My Ultrastodio 4k mini is flickering/tearing on the front display when outputing uhd 60fps using decklink output from OBS. Using 30fps it all works fine.
The ultrastudios output sdi shows black when trying to connect it to an ATEM using 60 fps, so its not just the screen.
I have tried it on two reinstalled and clean macbook pro computers testing on the two latest versions of OBS, testing the two latest drivers from blackmagic for the Ultrastudio. One of the Macbooks is the latest gen of i7 and the other runs a m2 processor.
I have tried using two different thunderbolt cables (thunderbolt 4 and 5. About 0,5m) from two different brands (one being the offical Apple thunderbolt 5 cable).
Multiple reboots.
Tried with "Force SDR" set to on in OBS output. "Keyer" on and off. All the same.
What could be the issue? Am I missing something?
