I have a HP 27f 4K Display that I am trying to connect to my MacBook Air M1 but it is not detected. It works fine when I try to connect a HP P24h G4 display. Both displays I connect via a HP Thunderbolt G2 230W dock station.
When reading the specification my MacBook Air does support 4K displays. I have also tried to connect the HP 27f 4K display to a PC via the dock station and then the screen works just fine.
