I have the same exact problem as the OP. I just recently bought a Sony 43" 4k TV (XBR43X830C) for a pretty good price since I work at Best Buy and get employee discounts. It provides 4 HDMI ports (seriously would it kill you guys to include a displayport) and have only been able to get 4k running at 30hz on my hackintosh. Works great on windows at the full 60hz, so its definately a driver problem. I've scoured all over the internet to find a fix but apparently no one has found one yet.
Since theres no fix yet and I absolutley dread using Windows (yuck), I've decided that I'll just write the drivers myself. I'm about maybe 25% done but its not easy (alot of math involved), I've only managed to get it running stable at 50hz but theres timing issues where the screen will cycle every 3-4 minutes (really annoying), so I'll have to read up more on the HDMI spec (if anyone is a graphics driver/EE expert please feel free to chime in). I'll try and finish up the drivers when I can but work has been keeping me busy
Daunting job for an individual and should not be necessary at all. Going to point the finger at nvidia here and hope they get their act together soon.
