Broadcasting your favorite movie from a smartphone screen to a large TV screen LG is a task faced by millions of users. Wireless connection via Wi-Fi eliminates the need to buy additional cables and adapters, but often raises questions: why the phone does not see the TV, how to turn on Miracast on LG Smart TV, and which broadcast method to choose for stable playback without lags. This article will help you understand all the nuances - from preparing devices to eliminating common errors.

Modern TVs LG (series OLED, QNED, NanoCell and budget UK6200/UK7500) support several wireless transmission protocols: DLNA, Miracast (via Screen Share) and proprietary technology LG Smart Share. However, not all of them are equally convenient for watching movies. For example, DLNA only allows you to broadcast media files from the gallery, but Miracast duplicates the entire smartphone screen, which can lead to audio delays. We will look at all the options, their pros and cons, and also give recommendations for optimizing the connection for comfortable viewing.

1. Preparing your LG TV for a wireless connection

Before connecting devices, make sure that your TV LG is ready to receive the signal. Most connection problems occur due to disabled features or outdated software. Let's start with the basic settings:

First of all, check that the TV is connected to the same Wi-Fi networksas your smartphone. To do this, go to Settings → Network → Wi-Fi connection and select your network. If the TV is connected via cable (Ethernet), wireless broadcasting may be unstable - it is better to temporarily switch to Wi-Fi.

Next activate function Screen Share (for Miracast) or Smart Share (for DLNA):

  • 📺 Open Settings → All settings → General → Devices → Screen Share.
  • 🔄 Enable the option Miracast (may be called Wireless screen on older models).
  • 🔍 For DLNA go to Settings → Network → Smart Share and activate the function.

If there is no item in the menu Screen Share, update the TV firmware: Settings → Support → Software Update → Check for updatesOn models LG older. 2018 (LJ550V, UK6300), you may need to manually install the firmware via USB.

💡

If the TV does not find your smartphone in the list of devices for Screen Share, try restarting both devices and repeat the search. Sometimes it helps to disable the function Energy saving on the phone, as it limits background Wi-Fi activity.

2. Setting up an Android phone to broadcast to LG TV

Smartphone based Android (versions 8.0 and higher) supports wireless broadcasting by default, but some parameters require manual configuration. The main condition is that both devices must be on the same local network. If you use guest Wi-Fi or a network with client isolation (for example, in hotels), the connection may not work.

For Start by turning on the function Wireless display (aka Smart View, Screen Mirroring or Miracast depending on the phone manufacturer):

  • 📱 On Samsung: swipe down the notification panel → Smart View.
  • 📱 On Xiaomi/Redmi: Settings → Connections and sharing → Screen broadcast.
  • 📱 On "pure" Android (Pixel, Motorola): Settings → Devices → Broadcast.

3. Method 1: Screen sharing via Miracast (Screen Share)

Miracast is a standard for wireless image transmission that mirrors the smartphone screen to a TV in real time. It is suitable for watching movies from applications (KinoPoisk, Netflix, YouTube), but can cause audio delays (up to 200 ms) on weak routers. connection:

  1. On the TV LG turn on Screen Share (see section 1).
  2. On the phone, activate the screen casting function (the method depends on the model, see section 2).
  3. In the list of available devices, select the name of your TV (for example, LG_OLED55C1).
  4. Confirm the connection on both devices (you may need to enter a PIN code).

After successful connection, the smartphone screen will be displayed on the TV. Launch any video player or streaming application - the image and sound will be broadcast automatically. Please note:

  • 🎮 Audio delay (lip sync) occurs more often when viewing through Miracastthan through DLNA.
  • 🔋 Broadcasting the screen greatly drains the phone's battery - it is recommended to connect it to a charger.
  • 📶 For stable operation, the router must support the standard 802.11ac (Wi-Fi 5) or newer.
What to do if the audio and video are not synchronized?

If there is a discrepancy between the audio and video (lip sync), try:

1. Restart the broadcast.

2. In the TV settings (Sound → Sound synchronization) manually adjust the delay.

3. Use external sound (for example, connect a sound bar via HDMI ARC).

4. Go to wired connection via an adapter (if lags are critical). Method 2: Streaming via DLNA (Smart Share) Protocol USB-C → HDMI adapter (if lags are critical).

4. Method 2: Streaming via DLNA (Smart Share)

Protocol DLNA allows you to broadcast to a TV data-i="138">only media files (video, music, photos), but does not duplicate the entire screen. This is convenient for watching movies downloaded to your phone, as it eliminates lags and synchronization problems. To work you will need: LG only media files (video, music, photos), but does not duplicate the entire screen. This is convenient for watching movies downloaded to your phone, as it eliminates lags and synchronization problems. To work you will need:

  • 📂 Media files must be stored in phone folders (not in cloud services).
  • 🎬 Supported formats: MP4, MKV, AVI (with codec H.264), MOV.
  • 🔊 Sound: AAC, MP3, AC3 (on some models LG may not be played DTS).

Setup instructions:

  1. On your TV, turn on Smart Share (Settings → Network → Smart Share).
  2. On your phone, install the application for the DLNA server, for example:
    • BubbleUPnP (for advanced users).
    • LocalCast (simple interface).
    • VLC (built-in DLNA support).
  • In the application, select the file to play and click "Broadcast" → select your TV LG.

    • On LG TVs 2020 and newer (webOS 5.0+), the built-in DLNA server may conflict with some applications. If the video does not play, try disabling Smart Share on the TV and use a third-party DLNA renderer, for example Plex or Kodi.

    Method Pros Cons Best for
    Miracast Duplicates the entire screen, supports all applications Possible lags, battery drain Streaming services, games
    DLNA No delays, saves battery Only local files, not all formats Movies from the gallery
    Google Cast Stable work with YouTube, Netflix Requires support Chromecast (not on all LG) Streaming services

    5. Method 3: Using Google Cast (if supported)

    Some models LG Smart TV (starting from 2019 on webOS 4.5+) support technology Google Cast, similar to ChromecastThis allows you to broadcast content from supported applications. (YouTube, Netflix, Disney+) directly to the TV without duplicating the screen. The advantage of the method is the minimum load on the phone and the absence of lags.

    To check support Google Cast:

    1. Open the application, for example, YouTube.
    2. Click the broadcast icon (📺) in the upper right. corner.
    3. If your TV appears in the list LG, the function is supported.

      4. If Google Cast does not work:

      • 🔄 Update the TV firmware to the latest version.
      • 📱 Update the application on your phone (for example, YouTube or Netflix).
      • 🌐 Make sure that both devices are connected to the same network (not via VPN!).
      💡

      Google Cast is the most stable method for streaming services, but only works with supported applications. For local files use DLNA, for screen duplication - Miracast.

      6. Solving typical connection problems

      Even with correct settings, errors may occur. Let's consider the most common ones and how to resolve them:

      ⚠️ Attention: If the TV LG is not displayed in the list of available devices for broadcasting, check if your router is blocking multicast traffic (setting IGMP Snooping or Multicast Filtering in the admin panel). On some router models (TP-Link, ASUS), this option must be disabled.

      Problem 1: The TV does not see the phone.

      • 🔄 Reboot both devices and the router.
      • 📶 Check that the phone and TV are connected to the same network (not the guest network or different bands 2.4 GHz/5 GHz).
      • 🛠️ On the TV, reset the network settings: Settings → Network → Reset network.

      Problem 2: Video lags or slows down.

      • 📶 Reconnect to the network 5 GHz (if the router is dual-band).
      • 📵 Reduce the video resolution on your phone (in the player settings).
      • 🔌 Connect your phone to charge - power saving mode may limit Wi-Fi performance.

      Problem 3: No sound during broadcast.

      • 🔊 Check if Is the sound on the TV or in the application muted?
      • 🎧 Try connecting external speakers or a soundbar to the TV via HDMI ARC or Optical.
      • 🔄 Restart the broadcast or change the protocol (for example, from Miracast to DLNA).
      💡

      If the image is broadcast, but the sound comes only through the phone, check the audio output settings in the player application. For example, in VLC you need to select Audio device → LG TV manually.

      7. Alternative connection methods (if Wi-Fi does not work)

      If a wireless connection is not possible due to a weak signal or incompatible devices, consider alternative options:

      • 🔌 USB cable: Connect your phone to the TV via USB-C → HDMI adapter (support required MHL or DisplayPort Alt Mode). in LG with port HDMI (MHL).
      • 📶 Wi-Fi Direct: Some TVs LG support direct connection without a router. Activated in Settings → Network → Wi-Fi Direct.
      • 🖥️ Via PC: Start a DLNA server on your computer (for example, Plex Media Server) and broadcast content from your phone to the TV through it.

      For an adapter connection (USB-C → HDMI), you may need:

      • Adapter with support 4K@60Hz (for example, Anker 810 or Baseus).
      • Enabling the mode USB debugging on the phone (Settings → System → For developers).
      • Selecting a signal source on the TV: press INPUT on the remote control and select HDMI-port.

      8. Optimizing broadcast quality for movies

      To achieve maximum image and sound quality when watching movies, follow these recommendations:

      • 📶 Router: Use a dual-band router (5 GHz) with support 802.11ac or Wi-Fi 6. Disable neighboring devices that consume traffic (for example, torrents).
      • 🎥 Video format: For DLNA convert files to MP4 (H.264) with a bitrate no higher 20 Mbit/s (otherwise there may be stuttering).
      • 🔊 Sound: If TV does not support DTS, convert the audio track to AAC or AC3.
      • 📱 Phone: Close background applications and turn on Do not disturbso that notifications do not interrupt viewing.

      To convert video, we recommend using:

      • 🖥️ HandBrake (free, cross-platform).
      • 📱 Video Converter Android (for mobile devices).

      Setting parameters in HandBrake for LG TV:

      Format: MP4

      Codecs: H.264 (video), AAC (audio)
      

      Resolution: 1920×1080 (if the TV is not 4K)
      

      Bitrate: 15-20 Mbit/s
      

      Frame rate: 24/30/60 fps (depending on the source)

      💡

      For stable streaming of movies in high quality, use DLNA (for local files) or Google Cast (for streaming services, Miracast is suitable for temporary duplication). screen, but not for long-term viewing.
