Everything 4k Transcoding... How to get Directplay?

General Discussions
1

I have researched this a lot. I have tried playing with all the settings, both client and server. I am at my whits end trying to get 4k to stop transcoding.

I have a Windows PMS box. i7 4770k, SSD, RAID10 etc… Server sits on a gig fiber connection. Home connection is Spectrum 100meg.
I have 2 4k Televisions. One is a TCL p605 (ROKU TV) and the other is an LG (Web OS 3.5 or 3.6). Both are wired. (TCL only does 100m).

On the TCL I have DTS etc turned off. In Plex Client I have quality set to original, I have directplay force on (tried auto).

The files are all MKV. All HEVC. Some Are AAC 2 channel, some are AC3 2 channel audio.

For the life of me I can not get them to directplay. Is my only option to use MP4?

Any hints or suggestions are really appreciated. If logs would help I am more than happy.

(both audio and video transcode on every file).

Are you saying they are transcoding down to 1080 and you want to watch in 4K.
Do mp4 direct play?

Correct.

According to Plex’s documentation 4k should direct play with MP4 and 2ch audio. I have yet to find or make an MP4 4k so I have not tested it myself.

I can back that up as my few 4K mp4’s play.
I convert everything to mp4 but will find an MKV and try.

Figured out the problem (at least for the TCL).

I had to change the settings in Server-Web-Quality. Home/internet streaming was limiting to 1080p, changed to “maximum” and all is well for most of the files (mkv and aac/ac3 audio). I can’t quite get the 60mbps files to stream smoothly but thats just a bandwidth issue.

Nothing I have tried has presented success on the LG with WebOS 3.5/3.6 but after some searching it appears to be a problem with the Plex App for that version.

Are you on the same network? like at home and Lan or wifi? just curious since I’m considering the "43S405 " from TCL

My TV is on my home network (which is now up to a 100mbps down connection, it wasn’t at the time), the server resides on a business network with a 1Gbps up/down Fiber connection.
