Anyway, are you sure it can't even do 30Hz at 4k? Because if it can then that would sound like an HDMI 1.4 bandwidth limitation issue which can be worked around by using 4:2:0 chroma subsampling to reduce the bandwidth enough to run at 60Hz (though it effectively cuts the color information down to 1080p).
Oh dear, i was pretty tired and wrote monitor... It's a TV xD
As far as i can tell, i can only set the Hz rate in windows to 60 hz when the TV is set at 1080p resolution.
