Plex 4K Playback Help

Hiya,

Wasn't sure on where to put this so I figured here would be a place to start.

I cannot get Plex to playback a 4K blu-ray. (Yes, of my own Blu-ray). HEVC x264 MKV It's a big 46GB file for Justice League and I think it's something like 55mb/s ish.

My rough setup is as follows: - Ryzen 1600

  • 8GB RAM

  • GTX970

  • Media is on a 2TB 7200RPM HDD

  • PC Connected to internet via powerline adaptor/CAT5

  • TV is a Samsung 40" 4K HDR (UE40MU6120K) - connected directly to router via CAT5

  • Plex app runs on the TV

Now I think I know the problem.. Plex is streaming the file from the server via our internet. Which for us tops out at just under 40mb/s. This is obviously the problem right?

How do I solve this though? Can't Pex play back directly from the server locally? Although I think that depends on codec I guess right?

I'd really love for this to work. We did try making Plex transcode on the fly but my CPU couldn't keep up! (Plus turns out my OC of 3.9GHz isn't 100% stable as it locked up after about 10 mins -- been totally perfect for the last 8 months!)

Normally I just play standard HD when I use Plex which I love. Transcoding is a is a big fat hog. I have a 4790k running my server and it struggles with 4k. but its on wifi. So for this episode I am currently running a 50 ft ethernet cable to see if it makes a difference. Stay tuned.

Huge difference WiFi vs Ethernet streaming 4k. It was unwatchable with WiFi. Ethernet no problem at all. My internet is 50Mbps which is Megabits per second. If you meant your internet is 40 Mbps then it should be enough. If your TV has a USB input the same 4k movie played perfectly using a passport hard drive. Doesn't fix Plex but it does play direct.

Everything except our phones, is cabled.
