    Is it possible with the new MBPs? Apples adapter is limited to 30Hz I believe...

    For HDMI no (unless its version 2.0) but for DisplayPorts and monitors with USB C connectors the MacBook Pros should run 4k at 60hz without breaking a sweat.

    Last time I searched, there weren't any dongles/docks that properly handle 4k@60Hz.
    Get a DP -> USB-C cable or HDMI 2.0 -> USB-C cable instead.

    The US$150 CalDigit USB-C dock supports HDMI 2.0 and DisplayPort 1.2 (plus it has Ethernet, charges the MBP,...), so it should be able to run a 4k display at 60Hz. On their Facebook page they mentioned that they still have to test this setup, so I'd wait a few days before ordering it.

    PS: keep in mind that any dock that is not Thunderbolt 3 will drop USB speeds to 2.0 when running 4k/60Hz. But as the only currently available Thunderbolt 3 dock (from Belkin) is currently priced at US$430, this is something one might want to live with for the next months until prices drop.

    I'm in disbelief that Apple hasn't provided a solution themselves. Seems like 4k@60 should be a default capability today.

    Wait a second, so if I'm currently driving a Dell P2715Q setup (actually, I can drive two of these 4K monitors both at 60hz with my Late 2013 15") via Mini DisplayPort to DP, I will no longer be able to do this with the new machine over DP? These monitors do not support HDMI 2.0, so DisplayPort is the only option, and it works flawlessly in single stream mode.

    Can anyone for sure confirm this? That's a deal breaker on the $3800 machine I ordered, if we're now walking back display out capability - especially on top of losing the SD slot.

    Just tried the Satechi Slim dock which markets itself as a "4K" dock with my 2016 base model 13" rMBP. It refused to over 30HZ no matter what. It also got very hot when connected to my TV (4K@30HZ) to the point where it got uncomfortable to touch.

    You should be able to do this with either a TB3 dock or with 2x USB C to DP cables.

    Calm down. All you need is a new cable.

    It is max 4K@30Hz by default. 60Hz can be enabled with caveats.

    Edit: Oh, never mind. Missed the P.S.

    Ok so that allows for 60hz?
    --- Post Merged, Nov 3, 2016 ---
    I can't find one that supports 4k@60. Please post it if you know of one.
