Roku Premiere+ andLG OLED65B7A TV (4K + HDR)



Roku Premiere+

On the netflix and amazon app, playing a 4k HDR source will show on my TV "HDR" in the top right corner when the stream begins. This is how I know HDR is active. Without it, it will still play in 4K but without HDR.

In Plex 5.1.6 on Roku Premiere+ (the exact same setup as what works flawlessly in Netflix and Amazon) - the HDR does not show. So although the 4K sources appear in 4K, AND they appear without artifacts now after a recent update (thanks!), the HDR is still not functional. I have set the source to direct play, but still nothing. Any other settings to try? Or does this require another update by the Plex team?


I can’t find an official answer, but Plex + 4k + HDR from server, and depending on client, all require a special alignment of the planets. (so it seems from discussions on the forums).
It seems the 4k requirement alone is picky about what type of encoding you pass it, else it’s transcoded to 1080p.

I wouldn’t hold Plex to the blade on this as much as some might like - it seems the general support of ffmpeg (which plex uses custom version) and 4k hdr are at times questionable.

Still no luck here, can I get a plex response?


Nobody else has this issue, not being able to watch HDR content through Plex?


Sometime in the last week or two, Plex is now playing content that isn’t even HDR, through HDR mode on my TV. This makes less sense than before basically… and playback is also quite choppy now on the Roku with the plex app, anyone else experience this too?


Make sure it’s not transcoding at all. I had the same issue and it turned out it was trying to burn in subtitles so it wasn’t handling the HDR. Once I fixed that I was able to get HDR again through direct play.
