Have you tried holding the option key and clicking "scaled" in display preferences? Also try checking the low resolution options box to see if a 60Hz option appears.

Yes, and 30hz in grey
 
Check the usb-settings from the display. In the manual it is said that the settings for usb is set to be usb2 as a default.

(Not sure if the setting is only for the output or affecting overall settings in the monitor.)

Apple has explained how to use 4k monitors with macs and the specifications:

That is the default. But thanks
 
Have tou tried toggle the usb settings (3.1/2) from the monitor? I found from some german site that there is a bug and you need to switch it to enable 60hz otherwise it stays on 30hz.

"Achtung, damit die 60 Hz funktionieren, muss man im Menu den USB Modus zuerst kurz auf USB 3.1, dann zurück auf USB 2 schalten, sonst kriegt man nur 30 Hz! Ist wohl ein Bug, muss aber nur einmal gemacht werden, ist also kein Problem."

The link is dead

Because of tapatalk - there seems to be an error when opening links.

Done!! Thank you very much
 
Or you can just pick up an LG 24UD88... had no issues whatsoever with it. . straight plug and play.
however, it should be noted that I used 40Gb thunderbolt 3 cable. I have not tried the cheaper USB-C cable [such as the one included with the MbP as I have heard they're only 5Gbps and can't handle it.
