When I got 10.9.3, display on the ancient Dell 30" I’d had plugged into various Macs went south; It would only do 1080x1920, which looked like a bad cartoon. So I ended up with a Sammy U28D590D which is advertised as “UHD” which I think is the official term for 4K. It works really well, albeit at 30Hz, but that doesn’t seem to be a problem.
Back story · What happened was, I tweeted So, what’s a good 4K outboard monitor to get for my MBP? Where by “good” I include “cheap”. and a couple people tweeted back about this Sammy, and local dealer NCIX had ’em in stock at a fair price, so I placed the order. Fifteen seconds later several other people pointed out it wasn’t on the supported-devices list and I had a queasy feeling in my tummy, but hey, it’s all OK.

Dead easy to set up.
It has sockets for HDMI and DisplayPort; not having a DP-to-mini-DP adapter, I just hooked up the HDMI and that worked fine.
The OS X “Best for display” selection produces ridiculously, insanely huge fonts. The “scaled” options are 1280x720, 1920x1080, 2560x1440, 3008x1692, and 3840x2160.
It’s just got a stand; no height/tilt adjustments that I can see. Worked out OK for me but could be a problem.
OS X tells me it’s running at 30Hz, which I guess might be bad if I were playing twitch games, but for writing code and blogs and reading Web stuff, it feels like a non-issue.
The brightness/contrast/whatever menus are controlled by a little multiway jog button on the back of the screen, which is about a thousand times nicer than your average screen menu setup.
Even though I have good eyes for a greybeard, and run my MBP at max-rez, I couldn’t handle 3840x2160 on this puppy, I’m running at the second-highest rez, and there’s plenty of real-estate for my purposes.
I’m thinking that to make really good use of 4K resolution, you need quite a bit more than 28" of real estate.
