Modern televisions LG Smart TV They are multimedia centers capable of not only streaming video but also playing high-quality audio from various sources. Using a smartphone as the primary source of a music collection has become standard, and the desire to output this audio to a TV's powerful speakers is quite natural. Wireless connection Wi-Fi opens up wide possibilities for this, allowing you to transmit an audio stream without loss of quality and unnecessary wires.
There are several proven methods for synchronizing a mobile device and TV into a single network. The choice of a specific method often depends on your device's operating system, TV model, and personal preferences. In this article, we'll take a detailed look at the most effective technologies, such as DLNA, AirPlay 2 and proprietary solutions from LG.
Before beginning setup, ensure both devices are connected to the same wireless network. This is a fundamental requirement for most data transfer protocols to function. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, it's advisable for both devices to be in the same band to ensure a stable connection.
DLNA technology and the LG TV Plus app
One of the most universal ways of transmitting media content is the protocol DLNA (Digital Living Network Alliance). This technology is built into most modern TVs. LG and allows you to stream audio files directly from a mobile device. To use this method, you need to install a special app on your smartphone, which will act as a controller.
The official solution from the manufacturer is the program LG TV Plus, available for platforms Android And iOSAfter installing and launching the app, it will automatically detect the TV on the local network. The user gains access to the phone's file system and can select tracks to play through the TV's speaker system.
⚠️ Note: Some audio file formats may not be supported by your TV's built-in player. Before transferring a large collection, check the compatibility of codecs such as FLAC or ALAC with your model.
An alternative to the official software can be third-party applications that support the standard. DLNAThey often feature more flexible equalizer settings and an interface familiar to music lovers. It's important to have the signal reception function enabled in your TV settings, which is usually enabled by default in the "Signal" section. Settings → Network → LG Connect Apps.
Using AirPlay 2 for iPhone Owners

To start playback, simply open the Control Center on your iPhone or iPad and select the Screen Mirroring option or the audio output icon in the player. Apple MusicYour TV will appear in the list of available devices. LGThe system will automatically request a confirmation code, which will be displayed on the TV screen, providing protection against unauthorized connections.
- 📱 Open the Control Center by swiping down (on new models) or up (on older models).
- 📡 Tap the "Screen Mirroring" icon or select the audio output device in the music app.
- 📺 Select your TV LG from the list of available devices.
- 🔢 Enter the code that appears on the TV screen if this is required for the first time.
Advantage AirPlay 2 The key feature is the ability to control playback directly from the lock screen or through widgets, without opening the app. This technology also allows you to create multi-room systems by streaming music simultaneously to several compatible devices in your home. Connection stability depends directly on the power of your Wi-Fi router.
What should I do if my TV isn't visible in AirPlay?
Make sure AirPlay is enabled on your TV in the "Support" or "General Settings" menu. Also, check if your router is in client isolation mode, which prevents devices from seeing each other on the network.
Streaming via Google Chromecast and YouTube Music
For operating system users Android and for fans of streaming services, technology is an excellent option Google Cast (Chromecast built-in). Many modern models LG have built-in support for this protocol. This allows you to stream audio from applications that support the "Broadcast" feature, such as YouTube Music, Spotify or Google Play Music.
The phone acts as a remote control, transmitting a link to the audio stream to the TV. The TV automatically downloads and plays the content, reducing the load on the smartphone and saving battery life. Sound quality is limited only by the internet connection and the service subscription.
To start streaming, open a supported app on your phone and look for the rectangle icon with waves in the corner of the screen. After selecting your TV, LG The music will start playing through its speakers. Track, volume, and playback queue control remain entirely in your hands.
Comparison of connection methods: characteristics table
Choosing the optimal connection method depends on your priorities: sound quality, ease of use, or format compatibility. Below is a comparison of the main technologies available for TVs. LGso you can choose the most suitable option for your situation.
| Method | Sound quality | Delay | Phone addiction |
|---|---|---|---|
| DLNA | High (Lossless) | Low | High (requires app) |
| AirPlay 2 | Very high | Minimum | Medium (phone control) |
| Google Cast | High (depending on service) | Low | Low (TV downloads itself) |
| Bluetooth | Average (compression) | Average | High (range) |
As the table shows, wired methods or direct network connections often outperform Bluetooth in terms of data transfer quality. However, wireless technologies offer unmatched usability. For listening to background music indoors, the difference may not be noticeable, but for critical listening, bitrate is important to consider.
Setting up a Bluetooth connection as an alternative
Although the topic of this article is about Wi-Fi, one cannot ignore the technology Bluetooth, which often serves as a backup option. If your Wi-Fi network is overloaded or your router is far away, Bluetooth can provide a stable, albeit lower-quality, connection. TVs LG equipped with a Bluetooth module that allows pairing with smartphones.
To connect, you need to go to the TV settings menu and select the section Sound → Sound Output → Bluetooth and enable device scanning. You should also enable Bluetooth on your phone and find your TV's name in the list of available devices. The pairing process is standard and takes no more than a minute.
⚠️ Please note: When using Bluetooth, there may be a slight delay in audio transmission, which is noticeable when watching videos, but less so for music. The range is also limited to 10 meters without obstacles.
This method is convenient because it doesn't depend on router configuration and works even without internet access. However, it's worth keeping in mind that Bluetooth audio compression protocols (such as SBC) can reduce audio detail compared to Wi-Fi transmission. While this is acceptable for a background party, it's not ideal for audiophiles.
☑️ Check before connection
Troubleshooting connection issues
Despite the ease of setup, users may encounter difficulties during initial setup. Often, the issue lies with the router's security settings or software versions. If the TV doesn't detect the phone, the first step is to check whether the "Client Isolation" feature is enabled on the router, which prevents devices within the network from exchanging data.
Another common cause is using different Wi-Fi frequency bands. Some routers separate 2.4 GHz and 5 GHz networks into different SSIDs. Make sure both your phone and TV are connected to the same network; even if they're on different bands, the router should route requests correctly between them.
In rare cases, a complete reset of the network settings on the TV can help. To do this, go to Settings → All settings → General → Network → Wi-Fi connection and select "Disconnect," then reconnect by entering your password. This will refresh the IP address and clear the network connection cache.
Frequently Asked Questions (FAQ)
Is it possible to stream audio from a phone to an LG TV without the Internet?
Yes, this is possible. If "internet" refers to access to the global network, then DLNA and AirPlay technologies operate within the local Wi-Fi network created by the router. Even without access to the ISP, as long as the router is turned on, file transfers between devices will work. You can also use a direct Wi-Fi connection (Wi-Fi Direct), if supported by the models.
Why does the sound cut out or stutter when playing?
Stuttering audio usually indicates an unstable connection or low data transfer speed. This could be caused by a weak Wi-Fi signal, interference from other electronic devices, or channel congestion. Try moving your phone closer to the router or switching to a less congested frequency.
Do older LG Smart TV models support AirPlay?
Official AirPlay 2 support is available on 2018 and newer models. For older TVs (LG NetCast or earlier versions webOS) This feature is not available out of the box. However, you can use third-party server apps on your PC or dedicated set-top boxes (Apple TV, Chromecast) connected via HDMI.
How to improve sound quality when transmitting via Wi-Fi?
For maximum quality, use lossless formats (FLAC, WAV) and protocols that don't recompress the stream, such as DLNA or AirPlay. Avoid Bluetooth if detail is important. Also, make sure unnecessary audio processing effects that can introduce distortion are disabled in your TV settings.
