    Does anybody have the new LG Ultrafine 5K Display (being sold by Apple, although currently out of stock) and can confirm that if you plug in the rMB over USB-C it will drive it at 4K and still be able to use the speakers and the camera for video conferencing?

    We're a home that uses rMB and rMBP and considering that monitor as the docking monitor but want to know if the rMB will work with it and also utilize its features of speakers, camera and other USB-C ports?

    Thanks

    Thanks for the replies, and I agree Apple's own website doesn't list the 2016 rMB as being able to use the LG 5K Ultrafine, however I assume they're only saying that because it won't output 5K.

    That said, the rMB will output 4K at 30Hz so if you plug it into the LG 5K Ultrafine with it's USB-C connection won't it send 4K at 30Hz to the monitor and also use the speakers and built in video for facetime? I assume the monitor can play 4K just fine so why wouldn't the 2016 rMB work?

    Thanks

    It's a Thunderbolt Display, meaning the only input is thunderbolt 3. The rMB doesn't have thunderbolt so isn't going to work with it.
    The 4K one will work with both

    You quoted the reference for the 4K display, not 5K.

    Thunderbolt 3 isn't compatible with USB C? I assumed it would at least drive the monitor with a 4K signal over the 5Gpbs USB C connector.

    USB-C is a connector, not a protocol: The MacBook supports USB 3.1 and DisplayPort over a USB-C connector
    The rMBPro supports Thunderbolt 3, USB 3.1 and DisplayPort over the USB-C connector

    The 5K display is Thunderbolt 3 only (which is how it manages to provide the web cam, and 5Ghz USB-C ports on the back), so there is no common protocol for the rMB and 5K display to talk to each other
