    This is what I have been waiting for. A 13" MBP that can drive my 4K monitor at 60 hz. I tried 4K at 30 hz but there was too much lag. Before today only the 15" MBP with Iris Pro graphic would do that.
    The new Intel Iris 6100 does it for the new 13"...Great!

    Thank you Apple.

    Does this mean that the new 13" Macbook Pro (2015) with Intel's Iris 6100 on board does support Single-Stream Transport (SST) displays with a resolution of 3840 × 2160 pixel at 60 hz via DP 1.2/Thunderbold 2.0?

    Does anybody already has a 4K-display connected with DP 1.2 in SST-Mode with her or his 13" MacBook Pro (2015) and can confirm 3840 × 2160 @ 60 Hz without any display issues?

    Such a confirmation would be very, very helpful because my research results are contradictory:
    For example Apple's official statement says that 60 Hz is only possible with Multi-Stream Transport (MST) displays (see: https://support.apple.com/en-us/HT202856).

    If the 2015 Air can do it, I don't see how the 2015 Pro can't, considering the better GPU.

    OP, if you could let us know what monitor you're using. I've been looking for one but right now nothing less than around 450-500.

    My 24" Dell cost me $130.

    How else would they connect it? I don't believe HDMI supports 4K at 60 Hz.

    Then it clearly isn't 4K ;)

    Good to see you two getting along :)

    No mine is 1080 but it's just for work stuff, nothing exciting. Numbers, etc.

    And hey, got to give credit where credit is due.

    Has anyone tried the following setups to see if they work and without lag (at 60 Hz)?

    2x4k over DP
    1x4 over DP + 1080p over HDMI
    2x4k over DP + 1080p over HDMI
    - any of the above with the internal screen on

    Yes I understand that 60 Hz are possible.

    The question that I have is if the 60 Hz are only possible with MST-capable displays. However MST is a hack solution by sending 2 pictures - namely the left and right half - at 60 Hz to the display which has to understand this and combine them.

    If I am correctly informed only a few set of older displays support MST - for example those explicitely listed at https://support.apple.com/en-us/HT202856).

    Standard technology in newer 4k displays is SST however - please correct me if I am wrong.

    Therefore I was asking if there is anyone who can confirm 60 Hz with an SST display - for example Eizo's EV3237.

    ArsTechnica tested with a Dell P2815Q, a SST display: http://arstechnica.com/apple/2015/03/yes-the-2015-macbook-air-supports-4k-displays-at-60hz/

    Thank you very much for this info!
    This is convincing me more and more because Air < Pro.

    We will get a SST-display with MacBook Pro 13 (2015) within the next weeks and I will report you our experiences then.

    As I have promised, I want to report and confirm that MacBook Pro 13 (2015) works like charm with the UHD-Display Eizo's EV3237 at 60 Hz and with SST via DP 1.2.
    Thank you for your feedback!

    So we can run the MBP 13 2015 with a 4K as an EXTENDED desktop of the retina screen without any stuttering on any programs, 4K videos play smoothly and etc? I know the expose transitions are a little bit stuttery....

    Yes, we are using it as an extended desktop (connected via thunderbold) to the retina screen and did not noticed any stuttering on the programs.
    Additionally, we (which is: my boss, *gg*) are even using a 24" Full-HD Samsung as a third display (connected via HDMI ).
