Problem connecting pc to 4k TV

[OruamEntil]

Hi everyone,
I'm having trouble connecting my pc (with gtx770) to a 4k TV (samsung 48ju6000). In fact if I chose te 4k resolution for the tv I just can't anything and my tv gives my "no signal" error, but if i downscale to 1920x1080 everything works fine. I've got a 1.4a hdmi cable. Am I doing something wrong? any suggestions?

Your PC will need to have HDMI 2.0 for the TV to accept 4k from it. The set also has HDCP 2.2 copy protection that might be an issue as well.
