Could the recently announced Mac Minis power a theoretical 5K Retina display? I'm curious, assuming that the Thunderbolt bus has sufficient bandwidth, would the Iris Pro graphics be capable of driving a 27" retina display?
Doesn't look like it.
Best info I can find says it can do 3840x2160 resolution at 30Hz
Everymac hasn't been updated to include them yet, this was from zdnet - http://www.zdnet.com/new-improved-slower-mac-mini-7000034795/
