Hello,
This behaviour is one I have not been able to find elsewhere, and I thought I would report it.
So I am using:
MacBook Pro 13'' early 2015
MacOS 10.13.5 High Sierra
ASUS MB169B+
DisplayLink driver v4.3 beta 5
The behaviour I see is that the external screen mirrors no matter what. If I uncheck mirroring, it says it is extended and I can arrange and scale the monitors etc... but the monitor of my laptop and the external just mirror each other. If I click the DisplayLink AirPlay option, I mirror the external monitor, if I do not, I mirror the laptop monitor.
I am super confused!
Thank you!
A
