Why can't I direct play 2160p UHD on my TV without buffering issues?

Plex Players Smart TVs
1

So I have this 33.1GB big MKV file which I am trying to play on my LG TV. The Plex player (installed from the LG app store) is able to play the file for a few minutes but pauses then for a while and then runs smoothly for a few minutes again. The unpaused intervals vary in length.

I have two questions.

  • Why am I facing this?
  • How do I solve it?

More information about the setup follows.

Video File

Plex Server is on a QNAP TS-470 Pro. Not really able to convert videos, that’s why I am trying to direct play.

Plex Player is the newest LG version on a LG OLED65C9 TV.

The TV is connected over CAT6 1Gbps to my Unifi 16PoE Switch, exactly like the QNAP server.

Even if the TV had 100 Mbps network card I’d expect the video file to play without problems (Plex player shows a maximum of 42.5 Mbps). So what’s up?

I bet the answer is to buy nVidia Shield TV Pro :smiley:

TVs only have 100 cards in them, not gig and the hardware is usually crap. You may have better results using the WiFi on a good 5ghz connect.

This is true on my Bravias, but …

I mainly use my Shield :joy:

Or if you don’t want to use wifi… get a ethernet to USB adapter if your TV has USB input on it. It will be much faster. They are less than $30 on Amazon and I use them on my LG TVs.
