Works for me (Using it now). Samsung 40" 4K TV.
I use a Yamaha HT system receiver as a switcher and have the Mac Mini, Apple TV and Roku setup on it. It also lets me Bluetooth my iPad Pro to it for World of Tanks Blitz.

Does the Mac mini display at 4K?
Yes, but I use it at 1080 so that the text is not so tiny.
I believe that the 2010 will provide 1080 but won't provide AC wireless, which I guess the 2012 does not either.
I'm using a 2014 2.8GHz i5 with 8GB ram and 1TB Fusion drive.
