    Hello

    I am planning to buy a macbook pro 13' 2017 (Touch bar Version)
    and i want to know if this monitor LG27UD88-W can display
    4k at 60Hz via usb type-c

    I see many threads about issues at 30Hz and hacks to work on 60Hz via usb-c
    and i am bit confused.


    Also which types of macbook pro support 4k at 60Hz via usb-c??

    I'm in almost the same boat, about to receive my 2017 13" TB and also want to display 4K @ 60hz, but over HDMI.

    I've bought the requisite USB-C to HDMI 2.0 cable and just have my fingers crossed that it will work now...... good luck mate

    u2 Tom.

    With what monitor ? I read that with HDMI 2.0 you can achieve 60Hz if also the monitor support it.

    Iam still afraid the 30Hz issue that many people get on external monitors...

    As long as you have a supported USB-c to HDMI 2.0 adapter/ cable and the monitor supports HDMI 2.0, you will get 4k60. Totally supported on the MacBook Pro (2016 and later).

    It is actually a 43" curved Samsung 4K TV... It is a beaut, but I've been running it in 1080P since my current machine (late 2008 aluminum book, 2.4 C2D) can't output 4K, lol.

    I am also concerned about the 30Hz issue, but I've done all the research I can, I just have to see what happens when it arrives now - my main thing is I don't want to have to use SwitchResX or some third-party workaround to get it functioning - I want it to work natively, out of the box.

    Yep, I've actually gotten a couple of them that have excellent reviews - one just an adapter USB-C to HDMI female, and the other a full cord, USB-C to HDMI male. It is my understanding that these adapters simply take the USB-C and convert it to a displayport signal, then convert that to HDMI. This concerns me with lag and what not, but in a few days I'll know how it works. I'll try to report back too, since I've had a hell of a time trying to figure this out on my own...

    Welp, received my 13" TB 2017 yesterday and it does indeed do 4K @ 60 Hz @ 4:4:4 Chroma over a USB-C to HDMI adapter, but whenever it is unplugged, the Samsung TV I am using does not remain in PC mode and has to be manually readjusted each time. I am HOPING that this could be rectified by using a TB3 dock which will keep a powered signal going to the display even when the computer is not connected and thus retain the input settings... A big annoyance but not on Apple at least.
