Intel's TB3 controllers can't do both TB3 daisy-chain and provide two DisplayPort endpoints. That's why most TB3 docks that have two DisplayPort ports don't have a second TB3 port, and why the HP had to use MST to have both. It's also why 5k+ displays may or may not support being daisy chaining, depending on whether it's using two DisplayPort links.
MST isn't necessarily great because over an HBR2 link it doesn't have the bandwidth for dual 4k60, and there's still a lot of stuff that doesn't support HBR3 links. And MST + hotplug is still a mess. So you're just trading for a different set of confusion.
- izacus 6y agoWell the fact that Apple doesn't want to support MST on macOS doesn't help either. Funny enough, installing Windows on the same Mac makes MST work just fine.
- olyjohn 6y agoTheir push has always been towards Thunderbolt. I was disappointed in this decision, but not really shocked.
- washadjeffmad 6y agoApple advertised MST support for Sierra or High Sierra and never delivered. Like you mentioned, daisy chaining does work on the same hardware in Linux and Windows.
