Hi!
i have an MacBook Pro 2019 15 inch.
Modell: Macbookpro15,1
OS: macOS Monterey, version12.0.1
Does my MacBook support DisplayPort MST (Multi-Stream Transport) thrue one of the USB-C (thunderbolt 3) connections.
MacBook Pro 15″, macOS 12.0
There's no issue with increasing resolution. Windows running on the same Mac hardware works perfectly with daisy chained display port screens.
Most monitors and docs that contain USB-C hubs use MST to connect a second display - these simply do not work with any device running macOS. The only reason is that apple haven't cared to implement MST in their driver software.
If you want to be able to put down your MacBook, plug in a single cable and have all your screens working then you have to buy a separate hub with 2 display ports, and it has to be an expensive one which specifically does not use MST internally. (Try CalDigit)
Complain to Apple, but they are unlikely to listen but you should complain anyway.
> Then buy a Windows machine.
what a thoroughly unpleasant person you are
i mentioned that it works on windows only to illustrate that it was a software issue and that the hardware was full capable.
but you be you
Would be very useful to me and I suspect thousands of others.
it could support up to that max data rate or total resolution and show a message if your displays are too big. Many users get more functionality, some don’t but no one loses out.
--> Then use Windows if that is the most important feature for you.
This isn't a Windows forum, it's an Apple forum. We're using is as technical point to show it is possible. Quit trying to turn that fact into something you drag.
Regardless I'm not looking to throw more money at something that clearly the hardware already supports.
Again, I think lots of people here are taking issue with "modest size" displays hand waiving off all support vs a dialogue guiding what is or isn't support.
Readers/Responder here are almost all other Users like you, NOT Apple employees, and they may temper what they say with their personal opinions. No one HERE speaks for Apple, Inc.

<< Surely airplay is a software only feature - isn't it? >>
sorry, No. It uses a special display-generator that was built into Intel Integrated graphics, and is being replicated in Apple Hardware. It was never available on the MacPro [intel], because the Mac Pro never had Intel Integrated graphics.
<< Windows running on the same Mac hardware works perfectly with daisy chained display port screens. >>
Then buy a Windows machine.
MacOS supports MST over ThunderBolt, ONLY.
Could you please post a link to such an ad?
It runs my triple 1440p monitors just fine with my thinkpad.
I don't see how triple 1440p monitors are "limited usefullness". The dock can also run 2x 4K displays without any issue.
No such thing as "Genuine thunderbolt devices" or MST on thunderbolt.
There is thunderbolt, and there is Displayport MST over thunderbolt.
I used that term to distinguish between devices talking using ThunderBolt protocol, and devices merely using USB cabling, but not ThunderBolt cabling or not having ThunderBolt verification by Intel.
Thanks for restating the problem
Support Displayport mst
