Logitech BRIO 4k on MacBook Pro - in OBS only 720p

[SHentschke]

Hello everybody,
I have a Logitech BRIO 4k and a MacBook Pro from 2020 (Intel CPU).
Unfortunately I can only set a maximum resolution of 1280x720 in OBS.
In Logitech Capture I can set it to 1080p and also to 4k.
Can someone help me please as I can also affect OBS 4k or 1080p?
Thanks
Greeting
Stefan

Have you tried the High preset? I know with the Logitech C920s, the listed resolutions in OBS only go to 720p, but High gets you 1080.
