4k/ultraHD display for MacBook Pro?

5 years ago from , UX Designer / Front-end Dev

Is anyone running an external 4k display on a MacBook Pro? If so, what display is it and how does it perform?

I need to choose an external display and I would prefer 4k but it needs to be 27" (or more) and I'm struggling to find one that isn't expensive. I'd also be interested to know if a MBP can even drive such a display in the first place without performance issues.
