Recommendation for a suitable 4k hdmi extender?

[Amir_init]

Hi All

need some help with choosing the right hdmi transmitter/receiver, I have NVR in the loft with cat6 cable coming down to the living room, my previous hdmi sender/receiver went faulty so need to replace. The faulty one is 4k HD and I have seen 4k 60ghz, would this be ok to work on my tv which is pretty new 75" Samsung
