    Hello,

    I have seen forum posts and google searches advising it is now possible to connect a 2016 MacBook pro retina 2016 to a 4k monitor or tv and display in 60 hz.
    Does anyone know if this is possible on a 2015 model?
    if so how do I do this, a link would be useful with a process guide.
    I have connected mine to a 4k LG TV using hdmi and am able to scale the display to 4k, but the highest refresh rate is 30 hz.

    thanks,

    Did you make sure to use a high speed HDMI cable?

    Edit: Oh, and the advertisement for the 2016 model is that you can connect up to two 5k 60hz or four 4k 60hz... Your macbook can easily handle the single 4k 60hz.

    thought I did.
    using a sandstorm hdmi cable, specifications as below.
    • HDMI 2.0
    • Supports 4k Ultra HD HDR
    • Up to 27 Gbps - great for 4k HDR
    • Gold-plated connector

    Wonder if it not 60 hz.

    thanks,

    There's something about needing to press the option key to see the higher Hz options with some setups. Also some TVs only do 60 Hz for some of their ports. Your cable should be fine.

    It is possible, you need to connect with display port cable. HDMI in the notebook is 1.4 and will only support 4k@30Hz.

    I believe there are two ways to get 4k @60hz with the 2015 MBPro:

    First way:
    Minidisplayport (MacBook) to displayport (or minidisplayport)(monitor).

    Second way (monitor or tv must have HDMI port that supports HDMI 2.0):
    Minidisplayport (MacBook) to HDMI 2.0 (monitor) converter/adapter.
    (This -might- involve using "SwitchRes")
    These DO cost a little more than "just a connecting cable".

    Take a look at this:
    https://www.amazon.com/Club3D-CAC-1...8-2&keywords=club3d+mini+displayport+hdmi+2.0

    (Not sure if that's the right one, READ THE REVIEWS, they have others)

    If you try a Club3d, could you please do a followup post to this thread and let us know how it went?

    EDIT:
    For the second method, one must also use an HDMI 2.0 compatible connecting cable.
    MANY HDMI cables cannot carry data fast enough to produce a 60hz display.
    Be sure to get a "high speed" HDMI cable.

    Only the mini-dp ports support 4k @ 60. The HDMI port is just HDMI 1.4 (4K @ 30hz)
