It should work fine because the USB-C ports have DisplayPort signaling built-in and I would not expect any issues. https://www.displayport.org/displayport-over-usb-c/ HDMI 1.4 does not support 4k at 60Hz like HDMI 2.0 does but HDMI 2.0 is not supported as you found out. I have not tested USB-C to DP specifically with my NUC6i7KYK but it does drive 4k over DisplayPort which should be the same with USB-C to DP. I do get some weird artifacts like the screen "shaking" back and forth a bit until I launch Xorg which then works perfectly. Bryan
