High bitrate issue on TCL R635 TV

Server Version#: linux server plex server V1.21.1.3876-3C3ADFCB4-LS16

Player Version#: roku plex version 6.7 build 4

So, I just tried playing a high bitrate TV show and all of the episodes act exactly the same. They produce static on the screen that occasionally morphs to mirror something that would be in the picture. If I transcode, it shows fine, but obviously direct playback is what is desired. The files in question are approximately 30GB per hour of film and about 78mbps bitrate. I have tried selecting alternate audio tracks to see if they were causing any issues. There are no subtitles selected.

I am using the plex app through my TVs roku OS to play back media from a local server. Everything is gigabit and wired. Any help figuring this out would be greatly appreciated.

  • many tv/streaming devices are not designed for high bitrate 4k bluray remuxes
  • most tvs have only 100mbit ethernet (which is not enough for some content)
  • if dolby vision is involved, that is even more complicated

you may want to review the thread @ Plex, 4k, transcoding, and you for a lot of 4k background and info

also, to truly troubleshoot we need more info

Thank you for the reply. I had just finished figuring out that my TVs ethernet port is limited to 100mbps. Will check out the link.

They almost all are 100mbps. Most likely, for the company it’s about saving a tiny bit of money on each unit produced.

For some TV’s, you can plug in a USB 3.0 gigabit controller and get higher speeds than the regular ethernet jack! Also, strangely enough, some TV’s have wifi that can be faster than 100mbps ethernet. A few things to try researching, maybe you have options.

I think that TV has USB2, but even USB2 can do several times more than 100Mbps w/ a compatible adapter.

Roku only claims to support up to 40Mbps HEVC video, but often works with somewhat higher rates. On earlier TCL Roku TVs I wouldn’t expect full UHD BD rips to work; I haven’t tried a 2020+ model.

But static is really interesting. Excessive bitrate usually causes errors, or “slideshow” playback. Can you share mediainfo for that file, or a sample?

I’m away for the night, but when I have access to my computer tomorrow I’ll get the media info and post it.
