Playback quality issues on Samsung

Plex Players Smart TVs

Hi I got the same problem. I can’t see more than 720p 4mb/s.
This happened since February, 3 or 4 weeks ago. Before I could saw fine.
If I change the resolution up (like 1080p) the screen turn on all green

Please solution

Please details.
it’s hard to help if you hijack an existing thread and provide little to no additional information beyond “me too”.
e.g. of minimum information but not limited to…

  • what version of Plex Media Server do you have and on what platform?
  • what client/player are you using it with?
  • is this about playback in the same network or while outside your home network (remote playback)?
    • if we’re talking about remote playback… what upload speed you you get (server -> internet)
    • how is your client/player connected to the home network (e.g. wired vs. wireless)

  • what version of Plex Media Server do you have and on what platform?
    -Plex for Samsung: 4.25.2
    -Tizen: 2.4.0
  • what client/player are you using it with?
    -Samsung tv UE49K5500AKXXC (2016)
  • is this about playback in the same network or while outside your home network (remote playback)?
    -Remote playback
    • if we’re talking about remote playback… what upload speed you you get (server -> internet)

I test it whit my PC in OOkla speddtest
Lan:
download 402.25Mbps/ upload 660.03Mbps
Wiffi 2g:
download 42.20Mbps/upload43.79Mbps

  • how is your client/player connected to the home network (e.g. wired vs. wireless)

Morning!
I am testing more and the problem appears only in the files with video codec 1080p(HEVC Main 10).
Now all compress files is changing to this codec, more quality less data transmission.

What can I do to see this codec with my smart TV app
Plex for samsung: 4.25.2
Tizen: 2.4.0

Thanks

Ok… so just to get this straight (still a little confused):
You’re playing a video from your own Plex Media Server or from a friends server?
You mentioned that you are currently moving all your media to 1080p HEVC… so I suppose it’s your own media / your own Plex Media Server.

HEVC is quite demanding – from what I can find, the model you have supports HEVC but only certain profiles. That means Plex will most likely ask the Plex Media Server for a transcoded version.
You cannot change that on the TV. That’s up to what Samsung makes available to the apps (and of course what the TV supports by itself).

On what platform do you run your server? (e.g. a NAS, dedicated server…)?
If the server isn’t very powerful, it could be too much for it to transcode the HEVC material and therefore cause the low quality.

That being said… you will need to share some more details on your setup / what you play etc.

-it’s a friend server
-exactly the video codec with problems is HEVC 120 Main 10
On what platform do you run your server?
-linux

ok… if this is about streaming from a friend’s server. In that case… let’s check some potential limiting factors

Possible restrictions on your friend’s side

  • ask her/him to confirm how much internet upload speed they have on their home network --> that is more likely a bottleneck than your own download speed
  • if she/he have a Plex Pass… ask them if they have set a restriction in Settings > Server > Remote Access > Limit remote stream bitrate (this is an advanced setting – only available if they have a Plex Pass!)
  • if your client is not able to play the video directly, it comes down to the CPU power of your friend’s Plex Media Server… if the server is not powerful enough to encode the video to the maximum of the available network bandwidth, you will end up with a lower quality version (e.g. 720p @ 4Mbps).

Possible restrictions in the Plex client on your Samsung

Also… have you checked the video quality settings in your Samsung Plex Client? If this is remote playback – you might need to unlock a quality restriction on your end. For most clients you will find this under Settings > Quality (or Video Quality) > Internet Streaming or Remote Streaming. If your friend’s internet upload speed is really strong you could try setting this to Original / Maximum quality. – you might want to confirm this with your friend in order not to eat up all their bandwidth.

Possible restrictions of your Samsung TV

Do you get the same issues if you install Plex for Windows or Plex Media Player on your computer (trying to rule out / confirm if the issue is with the Samsung TV).
As stated above… the tv’s capabilities could also be the culprit… according to the manual, this tv supports 1080p HEVC at 60 fps max (30 fps for 720p or higher resolutions) and a maximum bitrate of 20 Mbps. So if the 120 in your codec (HEVC 120 Main 10) refers to the frame rate … that might already require the video to transcode.

Edit:
Link to the manual of the tv; video specs are described on pages 84-85 (other limitations described across the document)

One more thing…
I just learned that the Plex for Samsung app on non-4K TVs cannot deal with HEVC at all – so whatever other limitations there might be… Plex on the TV is definitely one of them. It requires the server to provide a transcoded version of the file as it cannot directly play it.

The green screen could mean that your friend’s video is in HDR while your TV cannot deal with that.
