Plex on your Roku TV, step by step

Plex is the long way round to live IPTV on the Roku TV, worth it if you already run a Plex server. A computer at home runs Plex Media Server and Threadfin, a free bridge that presents your IPTV Strong 8K playlist as a TV tuner, and the Roku TV shows the channels under Live TV. Expect about half an hour the first time.

Setup guide

The Plex app is free, but live TV through a tuner needs a Plex Pass, paid to Plex and separate from your IPTV plan. Whether it plays 4K depends on the model, so check the spec sheet before choosing 4K feeds. If it doesn't suit you, the 7-day money-back guarantee applies, and because plans are prepaid there's nothing to cancel later.

Have these ready: Plex on Roku TV

Plex on Roku TV: Have these ready

  • Your M3U playlist link and XMLTV guide link, for Threadfin
  • A computer or NAS that stays on, for Plex Media Server and Threadfin
  • A Plex account with an active Plex Pass
  • Plan on about 10 Mbps for each HD stream and 25 Mbps for each 4K stream

Installing Plex

Plex on Roku TV: Installing Plex

  • Choose a plan on the pricing page and order on WhatsApp; your M3U playlist link and XMLTV guide link arrive in about 60 seconds.
  • On a computer or NAS that stays on, install Plex Media Server and Threadfin, a free tuner bridge, and sign in to Plex with an account that has a Plex Pass.
  • Search the Roku Channel Store for Plex and add it to the Roku TV. Sign in with the same Plex account.
  • In the Threadfin dashboard, add your M3U link and XMLTV guide link, set the tuner count to the number of screens on your plan, and map the channels you want.
  • In Plex Media Server, open Settings > Live TV & DVR, choose Set up Plex DVR, select Threadfin as the tuner (type its address if Plex does not find it), and match the guide.
  • Open Plex on the Roku TV, choose Live TV and pick a channel from the guide.

After you sign in

Plex takes a few minutes to scan the tuner and match the guide. After that, Live TV appears in the Plex app on the Roku TV, with a guide grid by channel number.

If Plex won't cooperate

Plex on Roku TV: If Plex won't cooperate

  • Plex finds no tuner: type the Threadfin address by hand in the DVR setup, and check that the computer running it is awake.
  • A channel won't tune: another stream may be using the last tuner; stop it, or raise the tuner count in Threadfin up to your plan's screens.
  • Channels missing: map them in Threadfin, then rescan channels in the Plex DVR settings.
  • Stutter on the Roku TV: check the server is direct-streaming rather than transcoding.

Settings that help on the Roku TV

Plex on Roku TV: Settings that help on the Roku TV

  • Turn off motion smoothing if faces look plastic; leave it on for sports if you like the effect.
  • Switch the picture mode to Standard or Sports for live games; Vivid looks harsh on compressed feeds.
  • Install TV software updates; the app store serves builds matched to your firmware.
  • Tuner count: set it in Threadfin to the number of screens on your plan, so Plex never opens more streams than the login allows.

Not covered here? Send it on WhatsApp and a person on the support desk will answer, any hour of the day.

Can I use the same IPTV Strong 8K login on the Roku TV and another device?

Yes. The login isn't tied to one device or one app. How many devices play at the same moment is set when you order: one screen as standard, up to 3 on a single plan.

What if Plex shows no live channels?

Plex finds no tuner: type the Threadfin address by hand in the DVR setup, and check that the computer running it is awake.

Is Plex available in the Roku Channel Store?

Yes, Plex is in the Roku Channel Store. The live channels come from your own Plex Media Server, not from the app.

Can Plex play 4K on the Roku TV?

Whether it plays 4K depends on the model, so check the spec sheet before choosing 4K feeds. The channel also needs a 4K source and about 25 Mbps on your line.
