Hi all, newbie here. I just moved in with my girlfriend, and we combined our AV stuff - she has the Onkyo tx-nr676, and I have a Vizio P65. I can't seem to get HDR working on it. Using my PS4 Pro I'm getting 3840x2160 60hz in YUV420, but 2160p RGB isn't available. It says HDR isn't available, but I've directly connected the same cable from the ps4 pro to the TV and get it to work no problem. I put my receiver in "enhanced" 4k mode by doing the BD/DVD and standby trick. Is there another setting I am missing? Since plugging into it direct makes HDR work, I think this issue is on the receiver's end.
