    Only late-2013 rMBPs will support it.

    I don't think the above posts are correct. True, it may not drive 4K natively, but surely if I can do it with my 2012 MBA you can do it with your MBP. See my post here for a more complete description of how you can achieve 4K output with your machine. Just insert "MBP" where I've said "MBA" and you're good to go.

    I guess there is a bit misleading. Surely it will drive 4K but at 30Hz which is not recommended. I bought 4K monitor and macbook pro just for this and have to return it after a week of trying.

    Unless you would go for 15 inch macbook pro , I would not recommend using 4K at 30Hz. Even with that low refresh rate, you start streaming 4K on one screen, another one will slow down noticeably.

    There is workaround to drive 4K at custom 53Hz (which will only work one some screen, the screen like UP2414Q which is one I tested won't work), but you will notice some lagging on the scrolling and zoom due to fix animation to 60Hz made by Apple.

    Good luck.

    ----------

    Read carefully. Only late 2013 "15 inch" model will support 4K at 60Hz. 13 inch model will drive 4K at maximum of 30Hz due to Iris graphic limitation.

    I think my Mid 14 rMBP 15" would support it!

    No, I'm sure Mid'14 15" rMBPs will support it as well.

    rayGcon makes a good point about running more than one screen. If that's your intention, I think your machine will struggle. When I'm using my 4K monitor with my MBA, the MBA is closed and stored under my desk. I tried running the 4K display with my MBA open on my desk beside the monitor and that's a no go (though the MBP may or may not perform better).

    As far as running 4K at 30Hz, I really don't think the quality would be so poor that it wouldn't be worth trying. There are several YouTube videos posted by people using the very cheap Seiki 4K TV as a monitor. It, of course, is capped at 4K 30Hz, and many people say it performs totally adequately at that resolution and refresh rate for gaming and video playback.

    That's what I'm after. While I'll run my 4K display(if its possible) MBP will be closed. In that case will I be able to get 4k at 60HZ? I have purhcased Display Port 1.2 cable.

    There are 2 problems. The machine raw power and iris output capability. While closing the notebook will give more room for processing. It doesnt change the fact that iris wont output 4K at 60hz. If you really want to run it on bigger screen then you better buy 15 inche one.

    It will be 4K with refresh rate of 30hz.

    It will be fine. Most movie runs at 24hz. All youtube runs at 30hz. You will only see different from 60hz when you work or play game.

    I understand. While watching the video about Samsung 4K it says that if I connect via displayport 1.2 it will support 60HZ. Will the cable have effect on HZ?

    Your cable will support that refresg rate. But your machine on board graphic card will not.

    Thank you! Instead of 4K if I use it in lower resolutions will I get 60hz such as 2880 x 1620 pixels?

    it is possible. But you have to consider whether

    * your os support that combination of resolution and refresh rate
    * same goes for monitor
    * how acceptable you are regarding to scaling on 4K. My personal experience is not very good.

    To be honest. If you cant run it natively. Dont buy 4K. Wait until the technology is more mature. Get other screen that you can run it on its native resolution in the mean time. There is no point to get 4K if you cant use it at full potential. I learnt this hard way.

    I think my native screen resolution could go up to 2560x1800 and can I have the same on external display? Thanks!

    I guess you don't really know how computer work , do you?
    When we talk about native resolution, it means the monitor not computer. There is no such thing as native resolution for computer. It can drive any resolution as long as the hardware and OS permit.

    Let me give you simple and clear reply. If you want to use macbook pro 13 inches with external display. Get one with 1080P or 1440P. Don't think about 4K.
