SOLVED: 4K HEVC on 1080P Roku

[TheDreadPirate]

You did not enable HEVC encoding, "Allow encoding in HEVC format", so there's that. As for DTS passthrough, I can't find any specifics on what it can passthrough. Their docs just say "DTS". Usually they include WHICH DTS varieties they can passthrough. Nor does it specify if only certain models can.
