Trying to get 4k from pc to tv


Nov 16, 2016
Hey guys, i got a 4k tv recently and its great but, Im trying to get my pc to display 4k on it, i bought a hdmi 2.0 cable and ran it to the tv, it displays 1920x1080 just fine with no fuss but when i try to switch it up to 4k resolution it cuts off and losses signal.
I have a gtx 660, kind of old but it passes the 4k requirement on the nvidia site.
and the tv is TCL 55US5800.
