Has anyone been able to use DP 1.2 MST to daisy chain multiple monitors together?
I have 3x Dell U2415 monitors, interconnected via DisplayPort to mDP cables. If I connect a USB-C to DisplayPort cable from my MacBook Pro (15-inch, 2017) to the first monitor in the chain, macOS 10.13 Beta (17A306f) will extend my display to the first in the chain, but then the next 2 will only mirror the first.
My hope is to be able to connect 3 external monitors via 1 USB-C to DP cable, but use those 3 external monitors as extended displays, not mirrors.
