I bought an LG 49UB820V yesterday with the hopes of using it with my hackintosh on Yosemite.
I only get 4k@30Hz via the HDMI port on my GTX760.

On Windows 8.1 it works fine.

I have a GTX760 and have hooked the GPU HDMI port to the TVs 1st (first) HDMI port which has a label that says "4k@60Hz (HDCP 2.2), and as I said on Windows it works fine, but on Yosemite 10.10.3 I only get 4k@30Hz.

I have installed the latest nVidia WebDriver and I have tried the plist hack, as well as changed the system definitons, but nothing gives me 60Hz.

It HAS to be limited by software, because as I said before, again, it works fine on Windows.

Anybody has an idea?
