Server Version# Plex Media Server v1.32.1.7510-91e1e2e2c - NVIDIA SHIELD Android TV
Player Version#: Plex 10.0.0.4149
I have an Nvidia Shield Pro that runs Plex and Plex Media Server.
I have enabled maximum bandwidth for local and remote streaming on the Plex client.
I have disabled video transcoding on PMS.
My TV is 4K HDR10 compatible but no Dolby Vision support.
No issue with 1080p movies.
But 4K HDR always want to be transcoded.
1/ I enabled debug mode and tried to understand the logs.
Here is what i’ve found on server side :

I think the issue is this one :
Sep 28, 2023 21:40:35.478 [211284569280] DEBUG - [Req#1897e/Transcode] foo - video.colorTrc limitation applies: smpte2084 != bt709|bt470m|smpte240m|smpte170m|bt470bg|bt2020-10 [list]
smpte2084 seams to be part of HDR standard, but for some reason, Plex client says it doesn’t accept it. My TV is HDR compatible, and I can read this movie with VLC in 4K HDR.
Why smpte2084 isn’t added by the Plex client ?
2/ I’ve found a customized Plex profile for the Nvidia Shield,
As far as I understand, this allows more content (especially 4K HDR) to be direct play on Shield. If i got it right, then I’m a bit puzzled why Plex Team doesn’t include the file directly on their own app release. Maybe there is a good reason ?
Thanks for your help!
