Describe the issue

Big fan of the app.
When HDR is enabled on 26.4.1 on my new Philips 4B2U6603 the sliders for brightness and contrast don't work. Connection is thunderbolt. Not sure if the issue is Mac OS, the monitor or MonitorControl (4.3.3). Running on M4 Max.

The page on the known incompatibilities has not been updated for a while so I am wondering if m4 are also not fully supported.

Expected behavior

display should change brightness

Anything else?
