The hardware MUST be DP 1.3 for Windows and Apple displays to work. This theory helps explain why this MST issue has been present since they introduced Thunderbolt 2.0 in 2013. If the check fails, the port is downgraded to DP 1.2 and you can only mirror the display. Therefore I think macOS is checking to see if the connected display is an Apple Cinema display and/or legit thunderbolt device.
And in fact, if you daisy chain multiple non-Apple displays together but hang a thunderbolt device somewhere in the chain it WILL daisy chain as well!Īs you say, the hardware works to daisy chain in Windows. I think the plot is a bit thicker because macOS WILL do MST when you use an Apple Cinema display. With Windows, the dock can drive two separate external displays on a capable Windows system."

While Apple says its 2015 and later MacBook Pro models can handle an MST display, handling two displays is off the table for now. This manifests itself both as monitors that combine two streams into a single display, and as adapters like this one that can split two desktop signals to appear on two separate displays. MST differs from single-stream, in that it allows multiple distinct video desktops to pass over a single connection. The company says that stems from a choice Apple made in implementing multi-stream transport (MST).
But as noted above, it can’t drive two external monitors as distinct displays through its two ports. review-a-full-featured-usb-c-dock-with-b…ĬalDigit’s dock supports up to the 4096 x 2160 pixel resolution at 60Hz maximum on the MacBook Pro. Has anyone been able to do this? I would appreciate any help you can give. Behind, at the base of the iMac Pro, you get a 3.5mm headphone jack, SDXC card slot, four full-size USB 3.0 ports, four Thunderbolt 3 USB-C ports and a 10Gb Ethernet port, which affords blazing. Ever dock I look at that has 2x outs says that the new MacBook can only mirror two displays. I'm trying to get 1 usb c cable out of our new 2016 MacBook to drive to external displays (not mirrored but extended).
