Docked displays being recognized as one...
I have my 2019 base MacBook Pro plugged in to an HP USB-C dock with three displays connected, when I plug in my HP laptop all three displays work as three individual displays, but when my MacBook is connected, it sees the three displays as the same one, only allowing mirroring.
