Issues with Dolby Vision on LG TV

Plex Players Smart TVs

I am playing movies from my local Plex server to my LG TV that supports Dolby Vision, yet I still get the wrong color (pink/blue) when playing DoVi files. Could one of you gurus please lend some advice? Is my TV not working correctly?

If you search this forum you will find multiple topics about it. In short: The LG TVs can only play Dolby Vision in MP4 files, but not in MKV files. This is a limitation of the TV itself, not of Plex.
So if you want Dolby Vision, you need to remux the file to MP4.

The reason why your second file “works” is that it contains both Dolby Vision and HDR10 data. You can see this in the “HDR format” line of MediaInfo. In that case Plex will just play the HDR10 version.

Thank you so much. I now have an automated script that will convert DV files to mp4 using ffmpeg.

Do you know if there is information on TVs that will play DV MKV files?

No idea, sorry.
