I don't mean to be "that guy"... because this is, of course, about linux running 4k. But much of the discussion seems to be around what the point is, whether it's useful, and so on. As someone who's been using one of the new 5k iMacs since it came out (so that's 5120x2880 in a 26" display)... let me add a bit, hopefully without sounding like an apple fanboy. First - running it at actual 5k, rather than at 3200 or 2560 HiDPI, is crystal clear, amazingly sharp, but too small at this size. With a 40" display it would be perfect, I imagine. At full 5k, you can fit an amazing amount of stuff on a single screen, and it's handy for certain short troubleshooting sessions - but stuff can be so small it's straining. The stuff is still crisp though, if you can manage to focus on it. The detail is there. 12 point fonts are barely readable to my 40 year old eyes unless I get closer. 3k is just fine, and 2k is what you'd expect - but both are using HiDPI rendering and you get stunningly crisp fonts and detailed images and whatnot. I wouldn't trade it for anything, even if I don't run in 5k all day long.
