Mac OS Sonoma beta 14.5 - Macbook Pro M1
With the update to beta 14.5 23F5049f it is no longer allowing detection of an external monitor.
Before the update, this would automatically make the external display the main monitor when connecting the USB-C cable.
Have tried the different USB-C ports, also turning on and off the computer and monitor separately but not being able to use the secondary display
