How to Add M3U to Samsung Smart TV
Connect your authorized M3U source after installing the Samsung Smart TV edition.
Screen TV does not provide IPTV subscriptions, channels or copyrighted content. Users must provide their own legally authorized content sources.
Download Screen TV
Installation
Open Home → Apps on your TV, search for Screen TV, and install the app. For the existing USB installation walkthrough, open the Samsung installation guide.
M3U and M3U8 setup
Open the app and note the device details if prompted. In playlist management, add the complete M3U or M3U8 URL from your provider. Keep query parameters intact, save, and reload the playlist.
Troubleshooting
If the app is missing from the store, check your model and store region. If a playlist fails, verify the URL or credentials, subscription validity and connection limit with your provider. For one failing channel, test another source before changing device settings.
