Use an external GPU ("eGPU") over Thunderbolt. I see no reasons for it not to work. Works on 2011, 2012 and 2014 Minis, just need a Thunderbolt port. 2011 and 2012 thunderbolt1 is capped at 10Gbps. 2014 thunderbolt2 (20Gbps) can leverage the full 16Gbps of the pcie2.0 4x interface to the thunderbolt controller. Difference should be negligible in non-gaming (or non-3D) workloads (and really, don't expect to do gaming in 12K with this setup). Still I find nicer to have TB2, so props to the 2014 Mini here. Full of guides here: http://bit.ly/10sVFdI A currently favorite setup is: - Akitio Thunder2 box - Gigabyte GV-N970IXOC-4GD (short gtx 970 to fit in the box, plenty of ports) - molex powered pcie 16x riser - silent PSU of your choice Roughly 600$ of a workaround. Notice how the aforementioned gpu has three Displayport 1.2 ports. Each port would drive a 4K display @60Hz in a "MST" fashion (single tile 4K 60Hz will only be possible with the upcoming DP 1.3 interface). There's also an HDMI 2.0 port, also capable of 4K @60Hz on monitors with HDMI 2.0. This is with GPUs available today, but 12 months from now you could easily have triple DP1.3 and drive even crazier configurations. This thread is basically for the "omg when 4K displays get cheaper, I'll be forever cut out of the 4K revolution if I buy a current Mini" crowd. No you won't. Not necessarily. Don't quote me on that (wasn't able to find any example of people doing it under OSX), but apparently 12K 60Hz is already possible, even with a 2011 Mini. By the way nMP (2013) can do 12K, but the third 4K display will be limited to 30Hz or limited color space because of HDMI 1.4. The upcoming nMP (2014) will fix that with HDMI 2.0. So a 2011 Mini with a 2014 eGPU can do 12K better than a 2013 nMP. Somehow.
