“Is HDR only available on HDMI 1? I am using HDMI 1 for Arc over to my Bose sound bar and I am trying to run Apple TV 4K on another HDMI but it will not operate in Dolby vision or HDR. Thoughts? All HDMI cables are high speed.”

• It may not from Apple TV but from my understanding it will support hdr from a source not running at a full 60 Hz. Maybe try to change your Apple TV to 30 or 24 Hz. I don't know much about Apple Tv's though.
