I know this has been asked before, but given the new Macbooks October 2016, and all these new Type-C USB/Thunderbolt ports that supposedly can do everything, I want to ask again, how is it possible to hook up two (DELL 2515H) monitors with DisplayPort 1.2?

Most notebooks I'm looking at to buy, they all have HDMI, newer models do not have mDP port anymore. But they all have USB-Type-C.

I am looking at a bunch of notebooks and they all have the USB Type-C port (Thunderbolt 3). But how do I physically make the connection? I know the wires are the same, so it should work just like that. Correct?

My observations:

  1. The miniDisplayport-Displayport cable won't work, the plug is different.
  2. There is no cable (at least I can't find it) that goes from Type-C----Displayport.
  3. There is no hub/adapter for Type-C port that offers a Displayport or miniDisplayport plug. There are hubs, but only with HDMI.
  4. You can't use the HDMI port of either the Notebook or the Hub, HDMI doesn't support miniDisplayPort 1.2 (needed to daisy-chain). Is that correct?

So how do you do it?

Again, this has been asked before, but thanks for clarifying.

  • USB Type-C is not Thunderbolt as far as I know and if you can't find an adapter you probably can't. Try to look for a way to attach one of those hubs/adapters? – Seth Oct 28 '16 at 11:48
  • @Seth AFAIK USB Type-C is everything: USB 3.1, TB 3, "alternate modes" such as display port, HDMI --- the new Macbook is even charged via the same Type-C port. However, the port itself isn't enough, it has to specifically support those "alternate modes". And that depends on the mainboard/manufacturer. I was able to find a USB Type-C to Displayport cable last night, made by Pluggable for 30 bucks. – John Oct 29 '16 at 8:36

    The USB type C PLUG supports a lot. The electronic parts on both sides of the plug also need to support the same language. Sometimes that is not the case (e.g. when connected to a plimple USB controller). – Hennes Apr 11 '18 at 13:35
  • USB-C is not the same as USB-C; some support alternate modes, some don't. Look very closely. – dirkt Aug 15 '18 at 12:51

The company that offers such a cable is Plugable. They have a bunch of adapters for USB Type-C ports to X, including Displayport for your monitors.
