    I have late 2013 Macbook Pro 15" with Nvidia 750M. I believe this model comes with Thunderbolt 2. From what I found online, this model can output 4k (3840x2160) at 30Hz over HDMI connection.
    My question is, could you possibly output this resolution over TB/DP port? Would this be limited to 30Hz as well? I was looking into getting new display and I guess 30Hz is alright but 60Hz would be better.
    Thanks for answers

    Yes you need a mini display port to HDMI 2.0 cable.

    something like this

    Cables do matter, a lot. But the MBP only has 1.4 HDMI output so that limits you to 30 Hz, The TB2 will act as a display port allowing 60hz to an HDMI 2.0 monitor input with the right cable or you can get a decent Mini DP to display port cable if your monitor has the latest DP protocol input but again the cost and quality can make a huge difference to lag and refresh rate.
