Jan 2, 2015 4:52 AM in response to Rüdiger Cordesby lllaass,Yes but not at 4K. When I connected my 24" Dell 4K, which works fine at 60Hz at 4K on my 2103 Mac Pro. I could get no higher than 1080p on my 2012 Mac Mini

I forgot to mention that I want the full 4k resolution.

Jan 2, 2015 6:27 PM in response to Rüdiger Cordesby Lanny,A 2012 MacMini can't support a 4k resolution. It's a hardware limitation, no OS X version or 3rd party software can change that.

Jan 2, 2015 7:13 PM in response to Rüdiger Cordesby Lanny,The same applies to all MacMinis prior to the 2014 model.

Jan 2, 2015 7:17 PM in response to Lannyby Rüdiger Cordes,Sorry, but you are wrong. At least a 2011 mini with the AMD Radeon HD 6630M supports 4k at 30 Hz.

Jan 2, 2015 7:39 PM in response to Lannyby Rüdiger Cordes,I know the answer to that mini with AMD Radeon, but not for my quad i7. So I asked it.
MacTracker is a good source but not always complete as we can see here. Ian could not know the compatibility with monitors which did not exist at that time.
Even playback of 4k-videos seems to be no problem with a HD3000: https://www.youtube.com/watch?v=y-PxQhaU82g

Nov 15, 2015 10:19 AM in response to Rüdiger Cordesby Rüdiger Cordes,I have tried it with a Mac mini 2012, 2,6 Ghz i7 Quad and OS X 10.9.4 and 10.11.1:
on both OS with 16 GB RAM a 4k-display via minidisplayport is booting and working @30Hz!

Nov 17, 2015 12:38 PM in response to Rüdiger Cordesby Rüdiger Cordes,Whereas with a Mac mini 2011 (only tested in 10.9.4, 16 GB RAM) as in the question it does not work. Seems it needs a HD4000. The Mini shows no content and has problems after connected to the 4k to boot with my normal monitor. Dont know what the problem is. Seems that the graphic is storing something tha avoids normal booting after testing. So if you like to test it your own, be warned and maybe dont try it with your main computer when you need it ;-)

May 19, 2016 12:50 AM in response to Rüdiger Cordesby Rüdiger Cordes,So, here is the answer:
A Mac mini Server 2011 with i7 quad at 2 GHz (only HD 3000 onboard) can not drive a 4k display. After connecting and not seeing anything on the display Mac mini has problems to boot. I dont know why but I can tell this as my experience. Mac mini has 16 GB RAM so with less RAM it is exspected not behave better.
On Windows PCs a HD3000 is able to drive a 4k display. So it seems that Apple just has no appropriate driver in the OS X software.
But a Mac mini 2012 with 2.6 GHz and 16 GB RAM is driving a 4k display at 30 Hz. 30 Hz means the content refresh rate. Movements are not so fluently - for exsample mouse movements. But the display rate is 60 Hz so you will not see a flicker. Even watching 1920x1080 (full HD) videos is not a problem. And the HD 4000 in the Mac mini has no problem to drive a 4k display over longer times, the temperature is not causing fan activities!
