I have a Samsung 55" 6290 TV that I'm using to play games on. However for some reason it is locking at 30hz at 4k even though its a 60hz tv. My system specs are as follows I7 6800k, 2 x FuryX, 16GB DDR4, Windows 10 and the latest Crimson Drivers. Any ideas what could be causing this or how to fix it?
