Late 2012 Mac Mini 1440p possible?

[Stavros75]

I will try this tomorrow with a friend of mine. Unfortunately this Mac has to operate on high sierra. It's the maximum I can get so I can connect to the servers at my work and also work with Adobe cs6. Old servers I guess and old programmes that they won't upgrade. So I must have the same equipment. That's what I've been told. Can't I get 2K with high sierra? Is there a bug or a bottleneck?

Guys to help someone with the same problem. I went nuts over this all night, I couldn't figure out what was the problem. The only thing I didn't check was the power cable. Well, I thought let's give it a try, changed the power cable, boom I have signal from the Mac mini. 2K resolution all good.
Thank you for your time to address my problem. 👍 I hope I helped someone here.
