Modern TVs LG with an operating system webOS or Android TV (depending on the model) offer many ways to interact with smartphones based on Android. However, not all users know how to make the most of this bundle. Connecting your phone to a TV allows you to stream video in high definition, duplicate the screen for presentations, play mobile games on the big screen, or even control TV using your smartphone.

In this article we will look at all current connection methods —from wireless technologies (Miracast, Google Cast, LG TV Plus) to wired solutions via HDMI or USB. We will pay special attention to setting without delays (critical for games and videos) and solving typical problems such as lack of sound or disconnected connection. If you want to turn your LG Smart TV into a full-fledged media center with integration with a smartphone, read on.

Spoiler: the most universal method is wireless broadcast via Wi-Fi, but for stability it is better to combine it with a wired connection via an adapter. And if you have an old TV model without Smart functions, don’t despair: there is a solution for you too.

1. Connection via Wi-Fi Direct (Miracast) - without a router

Technology Wi-Fi Direct (aka Miracast in the world Android) allows you to transfer images from a smartphone to a TV LG without intermediaries - no router or Internet. This is ideal for travel or places where there is no stable network. The main condition: both devices must support the standard.

To check compatibility, open on your phone Settings → Connected devices → Wireless broadcast (on Samsung this may be called Smart Viewon Xiaomi — Wireless Display). If the option is there, it means the smartphone supports Miracast. On the TV LG the function is called Screen Share (in the menu Network → Wi-Fi Direct).

  • 📱 On the phone: Enable Wi-Fi Direct in the settings and select your TV LG from the list of available devices.
  • 📺 On TV: Go to Settings → Network → Screen Share and confirm the connection.
  • 🔄 Synchronization: A request to start broadcasting will appear on the smartphone screen - click “Connect”.
  • ⚙️ Settings: In the broadcast menu you can select a mode - screen duplication or only media files.

Important: when using Miracast, the sound is transmitted to the TV by default, but some applications (for example, YouTube or Netflix) can block audio via this protocol. In this case, the sound will remain on the phone.

2. Broadcast via Google Cast (Chromecast built-in)

If your TV LG was released after 2019, most likely it supports Google Cast (analogue Chromecast, but without a separate device). This method is convenient for streaming content from applications like YouTube, Google Photos or Spotify —the broadcast goes directly from the cloud to TV without loading the phone.

To get started broadcast:

  1. Connect your phone and TV to the same Wi-Fi network.
  2. Open a supported application (for example, YouTube) and click the icon Cast (Wi-Fi screen icon).
  3. In the list of devices, select your TV LG.
  4. Start the video - it will start playing on TV, and the phone can be used to control (pause, volume).

Advantage Google Cast before Miracast: lower latency and the ability to continue using the phone during the broadcast. However, not all applications support this function - for example, TikTok or VK Video can block the broadcast.

⚠️ Attention: If the TV does not appear in the list of devices for Cast, check whether it is enabled function Google Cast Receiver in TV settings (All settings → General → Smart features → Google Cast). On some models LG This option is hidden in the developer menu.
How to enable developer mode on LG TV?

1. Go to Settings → General → About TV → Software information.

2. Quickly click 7 times on the line webOS Version (or Software Version).

3. Return to the main menu - a new section will appear Options developer.

4. Enable the option USB debugging (if you plan to use ADB).

3. Wired connection via HDMI (for games and 4K)

If you necessary minimum response time (for example, for mobile games like Call of Duty Mobile or PUBG), wireless technologies will not be suitable due to the delay. In this case, it will help wired connection via HDMI using an adapter USB-C/HDMI or Micro-USB/HDMI (depending on the phone connector).

You will need:

  • 🔌 Adapter USB-C → HDMI (for modern smartphones) or Micro-USB → HDMI (for older models).
  • 📺 HDMI cable (usually included with an adapter).
  • ⚡ Power supply for the phone (for long-term use).

Step-by-step guide:

  1. Connect the adapter to the phone.
  2. Connect the adapter to the TV LG via HDMIcable (use the port HDMI 1/ARC for better compatibility).
  3. On the TV, select appropriate HDMI-input as a signal source.
  4. The phone may ask you to select a display mode - select “Duplicate screen” or “Extend desktop”.

With this connection you will get Resolution up to 4K@60Hz (if the phone and adapter support) and less latency 10 ms —ideal for gaming. However, keep in mind that the phone will discharge faster, so it is better to connect it to a charger.

Adapter type Max. resolution Sound support Price (approx.)
USB-C → HDMI (passive) 1080p@60Hz No 500–1000 ₽
USB-C → HDMI (active, with chip) 4K@60Hz Yes 1500–3000 ₽
Micro-USB → HDMI (MHL) 1080p@30Hz Yes 800–1500 ₽
USB-C → HDMI + USB-A (for power) 4K@30Hz Yes 2000–3500 ₽
⚠️ Attention: Not all adapters support audio transmission via HDMI. If after connecting there is no sound on the TV, check the characteristics of the adapter or use a separate Bluetoothspeaker.

4. Using the LG TV Plus application (control and broadcast)

The official application LG TV Plus (available in Google Play) offers not only screen broadcasting, but also full control over the TV as a remote control. The application works on Wi-Fi and supports:

  • 🎮 Control of the cursor on TV using the phone's touch screen.
  • 📁 Transferring files (photos, videos, music) to the TV.
  • 🔊 Using your phone as a microphone for voice search.
  • 📺 Broadcasting the smartphone screen (analog Miracast, but with additional functions).

To configure LG TV Plus:

  1. Install the application on your phone and turn it on Wi-Fi on both devices (they must be on the same network).
  2. Launch the application and follow the instructions to find a TV.
  3. A verification code will appear on the TV - enter it in the application.
  4. After synchronization, select the desired mode: “Remote”, “Broadcast” or “Files”.

The advantage of this method is connection stability and additional functions (for example, you can use the phone as a touchpad for webOS). However, for video broadcasting it is better to use Miracast or Google Castas LG TV Plus may cause a delay.

💡

If the application does not find the TV, try manually entering the TV's IP address. You can find it in the menu Settings → Network → Network status on the TV.

5. Connection via USB (for older TV models)

If your TV LG does not support Smart functions (for example, models before 2015), but it does USB port, you can connect your phone to view media files. This method does not allow you to broadcast the screen in real time, but is suitable for playing pre-downloaded videos, music or photos.

Instructions:

  1. Connect your phone to the TV via USB cable (use a cable that supports data transfer, not just charging).
  2. On the TV, select the signal source USB.
  3. A list of phone folders will appear in the TV menu - select the desired file for playback.

Method limitations:

  • ❌ No screen casting - only file playback.
  • ❌ Not all formats are supported (for example, MKV or FLAC may not open).
  • ❌ The phone will discharge if not connected to a charger.

For stable operation it is recommended format USB drive (if you are using a flash drive) into a file system FAT32 —it is best compatible with TVs LG.

6. Solving problems: no connection, lags, no sound

Even with correct settings, errors may occur. Here The most common problems and their solutions:

Problem Possible cause Solution
TV not visible in the list of devices Disabled Wi-Fi Direct or Screen Share Enable the function on TV in Settings → Network → Wi-Fi Direct
