Describe the bug

I have Monitor Control v4.3.3 installed on both, an M4 Macbook pro running Sequoia and an M4 macbook pro running Tahoe. On Tahoe the same 2 external monitors either don't respond at all to brightness and contrast changes or respond after a good 10-20s.

Steps to reproduce

1. Connect monitors to macbook running Tahoe (in this case Tahoe 26.0.1)
2. Change brightness or contract either via sliders or keyboard

Expected behavior

Brightness and contrast changes happen in real-time in a continuous manner

Anything else?

No response
