Once an adapter is introduced, the game is over.

You can daisy chain multiple native Thunderbolt monitors on a single port. I don't know for sure, but I suspect this refers to monitors using the DisplayPort Alternate Mode on the Thunderbolt 3 chain. The new MacBook Air, 13-inch MacBook Pro, and Mac mini have only two Thunderbolt 3 ports for charging. You can read more about DisplayPort MST technology atĬurrently (April 2021), each Mac Thunderbolt 3 port supports only one display per Thunderbolt 3 port, and it needs to be the last one in the Thunderbolt 3 chain. AppleInsider has gathered the best Thunderbolt 3 docks to pair with your new Mac. If you run Windows 10 on the exact same Mac hardware, multiple monitors within the DisplayPort bandwidth work flawlessly as an extended desktop. Presumably, Apple regards MST Hub as a legacy, dead-end technology. Only Thunderbolt chained monitors are supported. Unfortunately, macOS does not support DisplayPort MST Hub. Without MST Hub support, multiple external monitors on the dock can only act as mirrors of each other. This technique allows multiple external monitors to act as extended screen area as long as the hardware and driver support MST Hub. The ThinkPad Docks use the DisplayPort Multi Stream Transport (MST) Hub standard on the two exposed DisplayPort ports. Use of the dock still doesn't increase the available video bandwidth of the Thunderbolt/DisplayPort port even if the machine itself has the capability. Unfortunately, you can't daisy chain monitors from a single port you must use separate ones. However, as you've already discovered, if you connect them separately, it works. Yes in that the MacBook Pro (as opposed to the MacBook) can support more than 1 external monitor. I should specify that my MacBook is actually MacBook Pro (15-inch, So, the mirroring you are seeing is expected behavior. The Lenovo C-Dock doesn't enable your MacBook to supply more display bandwidth than Apple provides. Resolution on the built-in display and up to 4096-by-2304 resolutionĪt 60Hz on an external display, both at millions of colors Per the tech specs:ĭual display and video mirroring: simultaneously supports full native In other words, it will only support one external monitor. The MacBook only supports dual displays including the built in display.
