I know there have been a lot of questions and threads regarding support for 4K monitor for a Mac Mini 2012. My config is a core i7 with 16GB of RAM and a Samsung SSD. I noticed Photoshop runs better and faster on the Mac Mini than on a retina core i5 MBP 2015 and I would like to use the Mac Mini for this purpose - So basically working with text and Photos retouching. I have no interest in watching movies, gaming or rendering videos on it. Therefore - I am having strong doubts about purchasing a 4K monitor since I understand at 4K resolution the refresh rate is about 30Hz. I cannot take the mac mini to the shop and test there.... store policies.... so I resort to asking anyone who has some experience with a 4K display on a mac mini late 2012. Can anyone please advise me if I should bother buying one? Currently I have no working monitor for it so I need to buy a new one. I know the mac mini supports 1440p resolution @60HZ - but how does the 4K monitor work in lower resolutions? Any advise is extremely useful. Thanks in advance.
