Secondary screen not working on MB Pro

[MariusROBERT]

Detailed Reproduction Path

I installed HyperHDR on my brand new MacBook Pro M5 and I can't make it work on my secondary screen, only for the main one (the integrated one).
On screen capture, I have Display 1 and Display 3 on the screen list, the first one is the integrated screen, the second one just don't work, on the LED visualization panel I got "No signal".

I had this exact setup working on my M1 MacBook Air but never on my new one, even with export/import the settings.

I managed to make it work by switching the secondary screen as the main one in macOS settings but after switching it back I got the same problem.

Have you tested the latest Github Action/beta build?

Yes, the problem still exists in the latest beta/Github Action builds

Did this work in a previous stable version?

No, it never worked for me

Hi
Could you test this installer and provide new logs when you switch between displays in the software grabber configuration?
