4K monitor @ 60hz with late 2016 MBP I have a new late 2016 MBP and a new Samsung u28ue590 4K monitor. According to Apples documentation:


  MacBook (Retina, 12-inch, Early 2016) and late-2016 MacBook Pro models support 60Hz refresh rates over HDMI when used with a supported HDMI 2.0 display, an HDMI Premium Certified cable, and a supported USB-C to HDMI 2.0 adapter


My setup have all those things I still cannot run my monitor at 60hz (it runs at 30hz by default, and I can't change it anywhere). Is it supposed to work out of the box or am I missing some configuration?

EDIT:
I have tried the following:


Boot in safe mode. This revealed the option to set the refresh rate, however only to 24hz, 28hz or 30hz. When booting normally this option was again not there.
Reset NVRAM. Did nothing.
Reset SMC. Did nothing.


I'm not sure this is a duplicate question as suggested in the comments as this monitor supports HDMI 2.0. If the monitor for some other reason doesn't support the 2016 MBP I would be interested in knowing that.

EDIT2:
I didn't manage to solve the problem with the current setup. It seems like Apple still has some work to do regarding HDMI 2.0 @ 60hz. It simply doesn't work out of the box, at least not with this monitor.
For the sceptics:

Safe mode reveals the option to change the refresh rate, but still doesn't allow more than 30hz.
Resetting NVRAM and/or SMC did not help.
I tried using another monitor (same brand), another late 2016 MBP, another Apple USB-C to HDMI adapter and several different HDMI cables.

However:
Using a USB-C to Displayport cable immediately solved the problem. I used this one: https://store.google.com/product/usb_type_c_to_displayport_cable
