IPTV on LG Smart TV — the complete webOS setup guide

Watching IPTV on an LG Smart TV — what you need to know

LG is one of the biggest Smart TV makers, and since 2014 its TVs have run webOS — a fast, well-designed system with its own app store, the LG Content Store. For IPTV this is good news: webOS supports dedicated IPTV apps you install straight from the Content Store, so you can watch live TV directly on the screen without plugging in a Fire Stick or Android box.

As with Samsung, the main IPTV app — Smart IPTV — uses MAC-address registration rather than an on-TV login. You register your TV's unique MAC address on a website and attach your playlist there. It's a quick step once you know the process, and this guide walks through it precisely.

StreamLux works on every webOS-based LG Smart TV. Once configured, you get 10,000+ live channels, the full movies and series library, and a 7-day EPG. See the complete channel list on our channels page, and all supported hardware on the devices page.

Does your LG TV support IPTV? Model compatibility

The deciding factor is whether your TV runs webOS. LG moved to webOS in 2014, and every Smart TV since uses it. Here's how the generations break down.

How to check your model

Find your model number in Settings → All Settings → General → About This TV, or printed on the back panel. A quicker check: if your TV has the webOS home bar that slides up along the bottom of the screen, with the LG Content Store and apps like Netflix, it runs webOS and supports IPTV.

If you have an older (pre-2014) LG TV

You can still use StreamLux. Plug an Amazon Fire TV Stick or an Android TV box into any HDMI port and follow our Fire Stick IPTV guide. This bypasses the TV's built-in system and works on any TV with an HDMI port, whatever its age.

Best IPTV apps for LG Smart TV

The LG Content Store has three solid IPTV options, none of which require sideloading.

Smart IPTV (SIPTV) — the most popular

Smart IPTV is the default choice on LG webOS, just as it is on Samsung. It's reliable, supports EPG and external playlists, and has a clean live-TV interface. It uses the MAC-address registration process (covered below) and carries a one-time activation fee of around €5.49 per TV after a 7-day free trial — paid to the Smart IPTV developer, not to StreamLux.

SS IPTV — the free alternative

SS IPTV is completely free and available in the LG Content Store. It's the choice if you'd rather not pay the Smart IPTV activation fee. You add your playlist via a link code or directly in the app, and it works well with StreamLux playlists.

OTT Navigator — for a more advanced interface

Newer LG models can run OTT Navigator, which offers a highly customisable interface, flexible EPG and multiple playlist support. If it's available on your model and you want more control over layout and playback, it's an excellent option that uses the same StreamLux credentials.

How to install IPTV on LG Smart TV — step by step

This walkthrough uses Smart IPTV, the most common app. If you use SS IPTV or OTT Navigator the credential details are the same; only the registration step differs. Our general setup guide has screenshots for each.

Step 1 — Install the app from the LG Content Store

From the webOS home bar, open the LG Content Store, select search, and type Smart IPTV. Install it. For the free route, search for SS IPTV instead.

Step 2 — Open the app and note your MAC address

Launch Smart IPTV. The welcome screen shows your TV's MAC address — a code like 00:1A:2B:3C:4D:5E. Write it down exactly, including the colons. It identifies your specific TV.

Step 3 — Register your MAC address and playlist online

On your phone or computer, go to the Smart IPTV activation page (siptv.app). Enter your MAC address, then add your StreamLux playlist. You'll have received either an M3U playlist URL or Xtream Codes details in your StreamLux activation email — enter whichever you have, and save it to your MAC address.

Step 4 — Enter your StreamLux credentials

The details to use are in your StreamLux activation email:

• If using an M3U URL: paste the full playlist URL into the upload field.
• If using Xtream Codes: enter the server URL, username and password.

These are case-sensitive. If you don't have your email to hand, contact support@streamlux.online and we'll resend it.

Step 5 — Reload the app on your TV

Back on the TV, close and reopen Smart IPTV (or use the in-app reload option). The app fetches the playlist you just registered and downloads your channel list and EPG. This takes 1–2 minutes the first time.

Step 6 — Start watching

Browse to any channel and press play. Your first channel should load within a few seconds. Channels are grouped into categories, and the EPG shows what's on now and next.

About the Smart IPTV app fee — what you're actually paying for

Worth being clear about, because some guides leave it out. Smart IPTV gives you a 7-day free trial, after which the app requires a one-time payment of around €5.49 to keep using it on that TV. This charge comes from the app's developer — it is not part of your StreamLux subscription, and StreamLux receives none of it.

To avoid it, use the free SS IPTV app instead, or run an Amazon Fire Stick with the free IPTV Smarters Pro or TiviMate. For most people the €5.49 one-time fee is worth the convenience of watching directly on the TV — but you should know it's coming before the trial ends.

Alternative: cast IPTV from your phone to LG TV

If you'd prefer to skip MAC registration, run IPTV Smarters Pro on your Android phone or iPhone and cast to the LG TV. On Android, use screen mirroring (Screen Share); on iPhone, the TV needs AirPlay 2 support (most LG models 2019+). This is handy for occasional viewing, though playing directly on the TV via Smart IPTV gives smoother, higher-quality playback for everyday use.

Internet speed for LG Smart TV IPTV

LG Smart TVs are convenient, but their built-in Wi-Fi can be weaker than a dedicated streaming device. Your connection is the most important factor for smooth playback.

Use the Ethernet port

Every LG Smart TV has an Ethernet (LAN) port on the back. If your router is near the TV, a cable from router to TV eliminates most buffering — built-in TV Wi-Fi is the single most common cause of freezing. If you can't run a cable, a Powerline adapter (internet over your home's electrical wiring) is the next best option at around €30–€50.

LG Smart TV IPTV troubleshooting — common problems

The five issues we see most often on LG TVs and how to fix each. For more, see our IPTV troubleshooting guide.

1. "No playlist" or the app loads empty

This means the MAC registration didn't link correctly. Check that the MAC address you entered on the Smart IPTV website exactly matches the one shown in the app (including colons), confirm your playlist URL was saved, then reload the app on the TV. A single wrong character in the MAC is the usual cause.

2. The app disappeared after a webOS update

LG firmware updates occasionally reset or remove apps. Reinstall Smart IPTV from the LG Content Store — your MAC registration and playlist are stored online, so your channels return automatically once the app is back.

3. Channels buffer or freeze

Almost always a connection issue. Switch to an Ethernet cable, confirm your speed meets the 4K requirement, and restart the TV (unplug for 30 seconds for a full power-cycle, not just standby). Clearing the app and reloading the playlist can also help.

4. EPG (TV guide) is missing or blank

The guide loads after channels and can take a few minutes initially. If it stays empty, make sure EPG is enabled in the Smart IPTV settings and that your StreamLux playlist includes guide data (it does by default). Reload the app to force a refresh.

5. Black screen on certain channels

Individual channels may be temporarily down at the source or geo-restricted by the broadcaster — outside StreamLux's control. Try an alternative stream for that channel if available. If a channel you rely on is consistently black, contact support and we'll check availability for your region.

Common mistakes to avoid on LG webOS

• Typing the MAC address wrong. One incorrect character means no playlist. Copy it exactly, including every colon.
• Letting the Smart IPTV trial lapse unexpectedly. After 7 days the ~€5.49 one-time fee applies. Decide before then whether to pay it or switch to free SS IPTV.
• Relying on TV Wi-Fi for 4K. Built-in Wi-Fi is weak on many models — use the Ethernet port for 4K to avoid buffering.
• Entering credentials on the TV when using Smart IPTV. Smart IPTV uses online MAC registration, not on-TV login. Register the playlist on the website instead.
• Not saving your activation email. Your M3U/Xtream Codes details are in it — keep it so you can re-register if you reset the TV.
• Assuming a pre-2014 LG will run modern apps. Older NetCast TVs won't — use a Fire Stick in the HDMI port instead.
