In my temporary setup, there are 2 external displays (both the same model) connected to a HP Universal USB-C Multiport Hub (one via HDMI, another one via DisplayPort), which is then connected to the laptop by USB-C.
Monitorian shows 3 displays (laptop + two external). However, both external sliders control the same monitor. In other words, one of external monitors cannot be controlled.
I've tried renaming one of the monitors, but it didn't help.
The probe.log reports both monitors to have Success: True, Match: True for SetBrightness. During the probe, however, the same external monitor got dimmed twice.
I have enabled "Record operations to log", then tried changing the brightness. After that, I was unable to copy the log due to a warning: Wait until more information is recorded to operation log. 56/10000. So I kept running it for multiple days, that's why the attached operation.log is so long.
