Check out this GAF thread. Collectively, we've figured out how to add an HDMI switch into the chain. Long story short, the PS VR Processing Unit is fickle, with special care needed for which HDMI cables are used.
They're full of shit, end of discussion. So long as the AVR is doing pass through, then you're golden.
I have a Pioneer Elite SC-95 and a Vizio P65-C1 and can display HDR through the PS4 with nary a thought.
Yeah, I can confirm again. I found out I have i/p conversion on on my avr, which is why it did not work in the first place. Once I turn it off everything works the way it should.
