By any chance do you know if the HDMI cable that comes with V2 is 4k ready and also, if there is a circle on it and the one for the ps4 pro. If I could pinpoint which cables are which as I've read older cables (1.3) can cause problems. I have three cables and teo have circular imprints in the adapters as the only defining factor.
Everything in the above reply is my opinion, from my own perspective and not representative of reality outside of my own head!
