Why it suits IPTV
- Fire OS, not Vega OS. You can install the IPTV player you prefer, including ones that aren’t in the Appstore, such as TiviMate. Vega OS sticks can’t.
- The most storage of any stick. 16 GB leaves room for a player’s channel list, logos and several days of TV guide, plus other apps, before storage warnings start.
- Wi-Fi 6E. On a router that supports the 6 GHz band, the stick gets a less crowded channel than older Wi-Fi.
- HEVC and AV1. It decodes the formats 4K channels use.
Set it up for IPTV
- Set up the stick and update it: see set up a Firestick and update a Firestick.
- Install a player. Follow install an IPTV player on Firestick. TiviMate’s developer gives the Downloader code 272483; see TiviMate on Firestick.
- Turn on frame-rate matching for smooth UK channels: see Match Original Frame Rate.
- Use the HDMI extender or, better, a cable through Amazon’s Ethernet adapter: see Firestick Ethernet adapter.
Limits to know
- No Ethernet port without the adapter.
- 10/100 Mbps with the adapter, which is still far more than a 4K stream needs.
- Heat: Amazon notes it may get hot during normal use. Keep it away from the TV’s back panel with the extender: see Firestick overheating.
4K Max, 4K Plus or Cube?
If you want a wired connection without an adapter, the Fire TV Cube has an Ethernet port built in. If budget matters more than storage, the Fire TV Stick 4K Plus runs Fire OS 8 with 2 GB of memory but 8 GB of storage. The full line-up is compared in best Fire TV for IPTV.
