I have just purchased a Samsung 65 in 2018 QLED tv ( QA65Q6FNASXNZ) and all went well until I wanted to view HDR from my new 4K Apple TV. There appears to be an issue with the Denon receiver (X4300H) and the Samsung TV that is known about (see link below). https://denon.custhelp.com/app/answers/detail/a_id/6849 Does anybody have a work around for this, I have done the UHD settings on and off and played around with different HDMI ports and the best I can get out of my Apple TV is 4K SDR, as soon as you turn HDR on, the screen displays the message that the source is not supported. The same holds true for my XBox oneX, SDR is fine, but not full HDR. Very frustrating as I spent hours trying to get it working before I found the link on the Denon website about the known issue with 2018 QLED TV’s. I don’t really want to buy some splitters and have optical cables for audio and then plug all my devices directly to the TV - that is why I have the Denon unit in the first place and my cables are all hidden in the wall and all my devices are in a cupboard, so it is very tidy and was working perfectly until I upgraded to the 2018 QLED.
