Hi,
Recently I’ve bought a Samusng TV 65Q60R. Today I setup a local network with new router https://www.tp-link.com/en/home-networking/wifi-router/archer-c7/ Unfortunalety all 4K videos buffering every 10-20 seconds. My interner speed is 600/50Mbps. I tested internet speed through cable and wifi on TV using page speedtest.net. I get 50/50Mpbs via cable and 70/50Mbps via wifi. I checked requirements on few movies in plex and they require 70-90Mbps connection. How do you think does TV internet card is so weak?
Thanks for reply.
Are you using the Plex app on the Samsung to connect to a local Plex Media Server or a remote Plex Media Server?
Plex media server was installed on PC in the same local network. Yes, I use Plex app on Samsung.
Okay, is the PMS wired or wifi?
Is the Samsung wired or wifi?
Are you using subtitles?
Last but not least, during playback on the Samsung, go to the Server Dashboard (through the web browser), take a screenshot of the Now Playing and post it here.
PMS is wired.
Samsung currently is wifi, but I also tryied wired.
Yes, I use subtitles.
according to this particular screenshot, you are direct playing video and audio, which is good.
This means either the connection simply isn’t fast enough (wifi or wired), or that the samsung hardware that runs the app isn’t powerful enough.
You could try turning off subtitles to see if that makes any difference.
Most tvs have only 100meg ethernet. 4k blurays can exceed that, so that can cause buffering or dropouts.
You could search for 4k samples of different sizes/bitrates and try to determine what the limit is.
Google for jellyfish 4k
also, you do not need to open multiple threads for the same problem.
Is it a way to measure a tv ethernet port? Other topic has a different problem with network not with a tv network speed.
you could check your tv manual, or google up the specs on the tv from the manufacturer.
or if you have a switch with a web interface, they will often indicate what the port speed is (ie 10/100/1000) for whichever port the tv is plugged in switch.
I asked technical support of Sumsung, but without success. The technical specs doesn’t include that kind of information. Even in technical site: https://www.displayspecifications.com/en/model/4d7918a0
Is the TV on the 2.4 or 5 GHz WiFi band?
Use 5 GHz if possible. If you’ve a decent signal, it will be faster than 2.4 GHz.
TV is connected to 5GHz WiFi. I found the reason of often buffering. For example if I choose another audio channel then video is transcoding instead of direct playing. My CPU Intel 4770 probably is not efficient enough to transcode 4K. If I choose original audio then video will play without problem.
Glad you found the reason. The screenshot you posted earlier shows everything direct playing. That was throwing everybody off track.
Here’s the rules for the Plex Smart TV app:
- Enabling image based subtitles, such as PGS & VOBSUB, will force a video transcode.
- SRT (text) subtitles direct play. However…
- If the audio is transcoding AND you have SRT subtitles enabled, then the video will also transcode. Plex must do this to keep the audio, video, and subtitles in sync with each other.
Your Samsung will direct play AC3. However, dts and TrueHD will transcode. So, if you’re playing a dts or TrueHD audio track, do not enable subtitles.

I think that the best way will be watch Full HD quality. I even tryied to force set desire audio channel at first(to not to use transcoding while changing audio) using MKVToolNix but saving takes too much time to use it on every movies.
