    Yes, but only at 30Hz.

    Not true. You have to read further down the page. 60Hz for Single Stream Transport Displays.

    yeah i believe higher resolution needs extra adapters, probably a display port adapter. the apple hdmi adapter seems to only support up to 1080p

    Per 9to5mac

    For Apple’s new 12-inch MacBook, the device will support displays running at a resolution of 3840×2160 at 30 Hz or 4096×2160 at 24 Hz over HDMI. Since the device only has a single USB-C port, you’ll need a USB-C Digital AV Multiport Adapter. Technically it’s possible Apple could support monitors hitting the market that use HDMI 2.0 at 60 Hz, but you’ll of course still need the appropriate USB-C adapter.

    If you want 60Hz on the new 12-inch MacBook, you’ll need an SST display, DisplayPort cable, and OS X 10.10.3. Although you’ll also need to get an adapter in order to go from the 12-inch MacBook’s 1 USB-C port to DisplayPort on the display— like this one.

    Additionally, Apple’s update to its 4k support doc confirms that it’s officially supporting Dell’s new UP2715K 27-inch 5K display following the OS X 10.10.3 update on the Mac Pro (Late 2013) and iMac (Retina 5k and 27-inch, Late 2014).

    A USB Type-C to DisplayPort cable like this one.

    Interestingly, Ars Technica was only able to get 30Hz (even on 10.10.3), despite Apple listing 60Hz support.

    Confusing it is...

    - That has been updated. It now lists 4K at 30Hz for the HDMI adaptor.

    That won't work while you're charging your MB. And you have to be charging your iPad for it to do video out with the lid closed. And I don't think the MB will do both the internal display and the external 4k display at the same time with any kind of decent performance. So I expect we'll still need a better adapter that does DisplayPort out.
