Support Displayport mst

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.

I think the gripe is that MST support for two 1080P monitors (like in work contexts/hotel cubes) isn't going to saturate anything. Windows loaded on the same Mac hardware works just fine.

Additionally, if you didn't think this was a market that needed addressing look no farther than StarTech. They've got docks that support multiple monitors BUT you have to load their displaylink drivers which aren't HDCP enabled and basically push the display over USB even though you're using the same USB-C cable. I'm using a Startech doc that only supports one 'native' display via HDMI, and the two Displayport connectors only work via USB/VGA/Displaylink goofyness.

From a usability perspective this is ridiculous. It doesn't matter what the 'working as designed' quip might be. It is not unreasonable for users with multiple monitors like two 1080P monitors to be hooked up without goofy solutions.

--> Then use Windows if that is the most important feature for you.

Using two cables to support two external displays is not a goofy solution, it is NORMAL.

Expecting the limited bandwidth of a DisplayPort cable to support TWO displays -- now THAT's goofy. If you want that, get a Thunderbolt-connected docking station.

...and since that MST-over-Displayport solution ONLY is possible when your two external displays are very modest sizes, Apple has chosen not to provide it as a general solution.

I have a CalDigit "USB-C Pro Dock" dock which connects via a single USB-C cable and has 2 HDMI ports. I've connected 2 2560x1440 screens and they work perfectly along with the inbuilt Retina display. The trick is that dock doesn't use display port MST - it makes the 2 screens appear as 2 separate "Thunderbolt/Displayport" connections.

Same amount of data over the same cable but in a way that macOS supports.

The dock built into one of the screens should do the same job but because it uses DP MST it's useless. Hence the need for an extra box and extra power supply on my desk.

It's not the most serious thing in the world but it does just seem stupid.

Like the option to airplay from my mbp to my tv that seems to have disappeared in one of the recent upgrades (yes I've checked the display settings - there's no airplay option there). I had to get a really long HDMI cable to watch anything that's only aired on paramount (and therefore not in the UK). Surely airplay is a software only feature - isn't it?

<< 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?

Apple does support MST -- Just not over DisplayPort.

MST is supported for genuine ThunderBolt devices, ONLY.

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
