apple studio display brightness setting by keyboard stopped working

I find F1/F2 key which used work as brightness adjustment stopped working for Apple Studio Display.

F1/F2 key brightness adjustment does work for Macbook Pro's display. Only not working for externally connected Studio Display.


Anybody having similar issue? Wondering if there's any resolution.


Studio Display (firmware version: 16.4)

Macbook Pro M1 2021 (MacOS 13.4)

MacBook Pro 16″, macOS 13.3

Apple's official support page, Set up and use Apple Studio Display - Apple Support does only say below. While it says about "reference modes", it also says "integration with ~~ lets you control brightness and sound".

Integration with macOS and iPadOS lets you control brightness and sound, and you can use the many reference modes in macOS to set your color space and other display characteristics.


Could I ask how did you know it's not supported?

I'll ask the Apple's support and will refer to that as well.

Yes, and to my understanding, thats more of profile settings a user may choose to use depending on their professional workflow.


My understanding of integration, which I enjoyed a lot til it stopped working is below.

Brightness adjustment key works, similarly to sound adjustment. (Note, both brightness / sound can be adjusted with slidebar drag. Why not with keyboard then..)

I've just booked a time with Apple support tomorrow, so I'll share the finding after the conversation there.
