Justin757 8 Posted January 15 Posted January 15 Mine lg cx support dolby vision when playing mov file from external storage attached to the TV. Played same file from emby, but it's only showing hlg hdr, no dolby vision. Even though it shows as 4k dolby vision in emby file info. I tested multiple mov files and all same, direct play from ssd = dolby vision Via emby = hlg hdr. Is it how this is?

If your TV havn't gotten or will never get the mentioned firmware you can fix it with a streaming box like the Nvidia Shield and watch from that connected to your TV instead. Another bonus from doing this is that you will get support for things like 7.1, atmos, TrueHD and so on if you have a surround receiver. 1

I think problem is with emby as everything else can play dolby vision in MP4 and mov file without any problem.

Try and move a mkv file to a USB stick and play it directly on the TV, if it can play it back as Dolby Vision there then the TV can do it and Emby is at fault. If not then it's the TV. As said, most LG TVs can't play Dolby Vision in other things than MP4 unless they got the firmware from LG to enable it. This makes it a whack a mole game for the Emby devs to trace down and enable it on the right TVs, so if yours is incorrectly set to not have it enabled it then check it like described and contact the developers. If the developers enable it on the wrong TVs people would just get black screens when watching Dolby Vision.

I don't believe LGs support Dolby Vision in mov files either. You can test it using the method i described just with mov format instead. Afaik Jellyfin can remux mkv and mov files to mp4 on the fly and support Dolby Vision that way. Don't know about Plex.
