MBP 2016 daisy-chaining
Hi guys
I have just received my brand new macbook pro late 2016 model with the Radeon Pro 460 4096 MB external- and
Intel HD Graphics 530 1536 MB onboard graphics.
What i'm trying to do is to daisy-chain my two Dell U2717D Display's so that i will end up with a total of 3 monitors. I cant figure out why it is not working, so i hope that you can help me out.
My setup:
Macbook Pro 2016 (monitor 1) is connected to Dell U2717D (monitor 2) through a usb-c to displayport cable. From the Dell U2717D (monitor 2) we have a connection to the Dell U2717D (monitor 3) through a displayport to displayport cable. The monitors are therefore daisy-chained. MST is enabled on the dell screens.
Outcome:
Monitor 2 is extending monitor 1 which is what we want. But monitor 3 is mirroring monitor 2 instead of extending. If i go to display preferences i can only see 2 displays. 1 built-in and one Dell U2717D (monitor 2).
I have installed windows on a bootcamp partition and if i boot in windows everything works perfectly. This leads me to believe that the issue is NOT hardware related.
Does anybody know whether there are issues with Mac OS X Sierra and daisy chaining?
Oh, and i tried calling Apple support. Talked with them for more than 1 hour without any use full outcome.
