No DolbyVision picture when eARC is turned off on Sony A80J


Novice Member
Hello community,

here is my Setup: 1x Sony A80J + Sonos Beam 2 + 2 Ones. If I turn off eARC in the Sony settings I don't get a Dolby Vision stream. It "decreases" the quality to regular HDR.

I would like to understand, why the eARC setting would affect the picture output? I thought eARC is only transporting the audio part. (Same behavior on Sony internal Netflix App as well as AppleTV)

Any ideas would be helpful.
