I bought a ps4 pro intending to use 4k on it. I have a Samsung 60 inch (ku6300) which I'm pretty sure supports the 4k..has a 10 bit panel im reading. And the necessary HDMI inputs. Anyway, on the ps4 pro, both 4k options aren't available. I do have a reciver that goes in-between the two. Could the reciver have something to do with it unsupported?
