Ich antworte mir mal selbst ...

Scheinbar ja.


Not every MacBook Pro is capable of driving a 4K display using SST. According to Apple, here are the Macs that can successfully drive a Single-Stream Transport 4K display at 60Hz:

MacBook Pro (Retina, 13-inch, Early 2015)
MacBook Pro (Retina, 15-inch, Mid 2014)
Mac Pro (Late 2013)
iMac (27-inch, Late 2013) and later
Mac mini (Late 2014)
MacBook Air (Early 2015)
Notice that even the Early 2015 and later MacBook Air can get in on the action. This is particularly interesting, since the MacBook’s Air’s own screen is a “normal” low-resolution display.

The main takeaway from this is that you’ll need a 15″ MacBook Pro from Mid 2014 or later, or a 13″ MacBook Pro from Early 2015 or later, in order to take advantage of 4K at 60Hz in the best way. Earlier models can work with 4K, but they use MST, and I simply can’t recommend that you take that route.

I also can’t recommend using any display running at 30Hz. Such a refresh rate results in a less than optimal user experience. The new 12″ MacBook, for example, can drive a 4K display, but Apple says it’s only capable of doing so at 30Hz.
