I use a Samsung U28D590D via Displayport 1.2 powered with an R9 R290. Running on Win 8.1 and at 60Hz.

Looks great, can play games at full res and most programs suit the dpi. No major problems.

However,

Linux is a completely different story. I had a hell of a time getting the drivers to work and after about a week of crashes, reinstalling and trying to tweak the size of things so they were visible I gave up and went back to M$.

So if you can bear Win 8.1 and have a powerful gpu, the reasonably priced Samsung is a good bet.

I use the same monitor via Displayport 1.2 powered by a GTX780 running on Windows 8. 4k resolution at 60hz. No complaints at all, great for desktop space and great for games.

However my late 2011 Macbook Pro or 2013 Macbook Air will not power that monitor at all, at any resolution.

I'm not a big fan of Windows 8. I do development on my desktop Linux box or Mac laptop. What Linux distro did you have trouble with using 4K? Any idea if Ubuntu 14.10 (Utopic Unicorn released this month) addresses any of the 4K driver issues?

I'm not a big fan of Windows 8 either.

Linux mint was the the distro I was using for their HiDpi support. I'm not sure if it matters that much as it's really the drivers that let it down. I also tried the latest Fedora but that failed to even boot on my machine... (probably wasn't monitor related).

To be honest you could probably get it to work with perseverance and Linux nohow. One of the problems I was having was that whenever I would wake the screen from sleep it wouldn't give me a login dialog and would require a hard reset. When I searched the problem I got the open-source blame shift, "it's their implementation that's broken. We're not changing our code" so I ragequit and went back to Bill.
