I guess I need more of a personal experience answer. The specications say that a Mac mini can support dual 4k monitors, but are there any caveats to this?

I am planning to get 2 x 4k monitors and run them both at 60hz, connected through DisplayPort (I will get Thunderbolt 3 to DisplayPort adapters).

Yes, the 2018 Mac Mini can support dual 4k monitors at 60 Hz connected the way you indicate. I have this setup myself. There are no caveats.

Note: You do not need an "adapter" as such. You just need ordinary, passive cables from Thunderbolt 3 to DisplayPort.

  • Thank you for your answer. Just to elaborate on what I meant, the displays come with a DP to DP cable, I wanted to get a thunderbolt 3(m) to DP(f) adapter. But I've also considered getting a thunderbolt 3 to DP cable. I ordered one from this company, called QGeeM, do you happen do know anything about them? – hey_you Jun 14 '19 at 3:09
  • Never heard of them. I use StarTech for this setup - works without problems. – jksoegaard Jun 14 '19 at 6:32
  • No wonder, they're all Chinese companies :D – hey_you Jun 15 '19 at 20:54
  • @hey_you StarTech is American, not Chinese. – jksoegaard Jun 15 '19 at 21:20
  • I have also same setup. The mac mini 2018 has 2 thunderbold controllers each driving 2 of the 4 ports. Would there be an advantage of plugging each monitor in one of the controllers or both in the same controller? Or even one in thunderbold and one in hdmi? – HixField Jul 25 '19 at 15:51
