How to connect your phone to an LG Smart TV via Wi-Fi

Modern users can no longer imagine viewing multimedia without the ability to instantly transfer content from a mobile device to a large screen. Wireless technologies allow you to get rid of unnecessary wires and enjoy videos, photos, and games in high definition directly on the panel. LG Smart TVThis turns ordinary viewing into a full-fledged home cinema or entertainment center for the whole family.

The process of synchronizing gadgets with a TV has become much easier thanks to the development of protocols Wi-Fi Direct and built-in smart platform features. You no longer need to search for adapters or HDMI cables if both devices are on the same local network. Just follow a few simple steps in the settings menu to start streaming.

In this guide, we'll cover in detail all the current methods for connecting Android and iOS smartphones to LG TVs running webOS. You'll learn the ins and outs of various apps, troubleshooting common errors, and methods for optimizing the connection for stable operation.

Preparatory stage: network and device requirements

Before starting setup, you need to ensure your equipment meets the basic requirements for a functioning wireless connection. A fundamental requirement is that both devices—the smartphone and the TV—are on the same Wi-Fi network. This means they must be connected to the same router; otherwise, they will not be discoverable.

Please check the wireless standards supported by your router. For high-resolution video streaming, such as 4K or Full HD, it's recommended to use a band 5 GHz, which provides higher throughput and lower latency compared to 2.4 GHz. Older routers may struggle to handle heavy content streaming, causing buffering.

It's also important to check the software on both devices is up-to-date. On an LG TV, this can be done through the system settings menu, and on a smartphone, in the operating system updates section. Outdated firmware versions often contain bugs that prevent proper handshake between devices from different manufacturers.

  • 📱 Make sure your smartphone's Wi-Fi module is turned on and active.
  • 📺 Check that your LG TV is connected to the internet and has access to your local network.
  • 🔌 Make sure that AP client isolation is not enabled on your router (guest network mode may block the connection).
  • 🔄 Update the LG ThinQ app or built-in Smart Share services to the latest version.

⚠️ Important: If your router is distributing two networks with the same name (2.4 GHz and 5 GHz), make sure that both devices are connected to the same one and not to different frequency ranges, as some router models may interfere with their communication.

Connection stability directly depends on signal quality. If the TV is located far from the router or behind thick walls, data transfer speeds may drop. In such cases, it is recommended to use a wired TV connection or install a Wi-Fi repeater to improve coverage in the viewing area.

Using Screen Share on LG TVs

The most universal method for LG equipment owners is the built-in function Screen Share, which is based on the Miracast protocol. This technology allows you to broadcast your smartphone's screen to your TV without the need for additional apps, creating a direct wireless connection between devices.

To activate the mode, press the button on the TV remote control. Input or Smartto open the signal source selection menu. In the list of available options, find and select "Screen Share" or "Connect to a mobile device." A connection waiting window will appear on the screen with the name of your TV.

On an Android smartphone, the process may have different names depending on the manufacturer's model. Typically, it's called "Cast," "Smart View," "Wireless Projector," or "Connect to a Wireless Display." Once the search starts, your phone will detect your LG Smart TV in the list of available devices.

After selecting a TV from the list on your smartphone, you may be asked to confirm the connection on the TV screen. Use the navigation buttons on your remote to accept the request. From this point on, the image from your mobile device will be mirrored on the big screen in real time.

  • 📡 The technology works without the Internet, using a direct Wi-Fi Direct connection.
  • 🎮 Ideal for displaying presentations, photo albums and mobile games.
  • 🔋 Your smartphone's screen can consume more power, so keep an eye on your battery charge.
  • 🔊 The sound is also transmitted through the TV speakers, providing surround sound.

It's important to note that when using Screen Share, your smartphone's screen stays on, and all notifications received on your phone will be displayed on your TV. This can be inconvenient when watching movies, so it's recommended to enable "Do Not Disturb" mode before starting your session.

Stream from iPhone and iPad via AirPlay 2

Owners of Apple devices can take advantage of native technology AirPlay 2, which is built into modern LG TV models supporting webOS. This solution ensures the highest quality video and audio transmission with minimal latency, integrating directly into the iOS system.

To get started, make sure your LG TV supports AirPlay 2 (2019 models and newer). On your TV, go to Settings and find the "Apple AirPlay Support" section, where you need to enable the feature. Afterward, your TV will appear in the list of available devices for streaming on any Apple device.

To start casting, open Control Center on your iPhone or iPad (swipe down from the top right corner or up from the bottom on older models). Tap the Screen Mirroring icon (two rectangles) and select your LG Smart TV from the list. The image will instantly appear on the big screen.

What to do if the code does not appear?

If a code is required when connecting and it isn't displayed, check your AirPlay privacy settings on your TV. You might want to temporarily set the setting to "First Time" or "Every Time" to see the prompt on the TV screen.

A unique feature of AirPlay is the ability to not only mirror your screen but also stream content directly from apps. For example, in YouTube or Netflix, you can tap the cast icon and select your TV. The video will play on the TV itself, and you can use your phone as a remote or set it aside.

Platform Android, Windows iOS, macOS All platforms
Transmission type Screen mirroring Duplication or flow Media files only
Quality Depends on the signal High (adaptive) Original file
Control By phone Via phone/remote control By phone

Apple's technology encrypts the transmitted stream, making it safe for use on home networks. However, it's important to note that screen mirroring drains the iPhone's battery faster than usual due to the active use of the wireless module and processor.

LG ThinQ App: Enhanced Control and Broadcasting

Official app LG ThinQ (formerly LG TV Plus) offers advanced TV control and media streaming capabilities. This software acts as a universal remote control and multimedia center, allowing you to not only display images but also fully control the TV's interface.

After installing the app on your smartphone and registering with the LG system, you need to add your TV to the list of devices. The app will automatically search for available TVs on your local network. Once paired, a confirmation code will appear on the TV screen, which you need to enter in the app.

The "Media Casting" feature in the app lets you select photos, videos, and music from your smartphone's memory and play them on your TV. Unlike full screen mirroring, the TV decodes the file itself, reducing the load on your smartphone and ensuring smoother playback.

Additionally, LG ThinQ lets you adjust picture and sound settings, change input sources, and even control some smart home features integrated into the LG ecosystem. This makes the app an indispensable tool for owners of LG appliances.

It's worth noting that a stable internet connection is required on both devices for all app functions to work, as some commands may be routed through the manufacturer's cloud servers, although basic broadcasting also works over a local network.

Connection problems and solutions

Despite the simplicity of the technology, users may encounter various difficulties when trying to connect a phone and TV. One of the most common issues is when devices simply don't see each other in the list of available devices. This is most often due to router settings or client isolation.

If the connection is established but constantly drops or the video is choppy, the problem lies in low Wi-Fi speed or interference. In this case, free up the Wi-Fi channel by switching the router to a less crowded frequency or by reducing the distance between the devices.

Sometimes, problems are caused by antivirus programs or firewalls on your smartphone that block local connections. Check your mobile device's security settings and ensure the streaming app is allowed to access the local network.

  • 🔄 Restart your router, TV, and smartphone—this solves 80% of connection problems.
  • 📶 Check if your router has speed limits for certain devices.
  • 📱 Uninstall and reinstall the streaming app if the problem is with it.
  • 🔌 Reset your TV's network settings using the menu Settings → Network → Advanced Wi-Fi settings.

⚠️ Please note: The menu interface on LG TVs may differ depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). The layout of settings items may vary, so please refer to the relevant sections for guidance.

In rare cases, the issue may be caused by incompatible video file formats when using DLNA. If the TV doesn't play the file, try using third-party players on your smartphone, such as VLC, which have built-in streaming and support more codecs.

Alternative methods and third-party applications

If built-in methods don't work or the functionality isn't sufficient, third-party solutions come to the rescue. Apps like Cast to TV, AllConnect or Web Video Caster allow you to stream content from virtually any source, including browsers and closed video players.

These programs often have more flexible settings, allowing you to adjust the aspect ratio, add subtitles, or change audio tracks on the fly. They can also emulate a DLNA server on your smartphone, making its files visible to the TV as network storage.

For users who want to cast a Chrome browser tab from an Android device or PC, Chromecast built-in is available. If your LG TV supports Chromecast built-in, you can cast browser tabs or content from supported apps directly using Google's standard protocol.

Using such solutions requires careful attention to security permissions, as the apps have access to your media files and local network. Download software only from the official Google Play or App Store.

Frequently Asked Questions (FAQ)

Is it possible to connect a phone to an LG TV without Wi-Fi?

Yes, this is possible with a cable. For Android and modern iPhones (series 15 and newer), a USB-C to HDMI cable will work. Older iPhones will require a Lightning to HDMI adapter. In this case, the TV acts as an external monitor, and a wireless network is not required.

Why doesn't my LG TV detect my smartphone?

The most common cause is that the devices are connected to different networks (for example, one to a guest Wi-Fi network and the other to the main network). Also, check if access point isolation mode is enabled on the router, which prevents devices from seeing each other on the local network.

Does phone connection affect internet speed?

When mirroring your screen (Miracast/AirPlay), you may not need the internet at all, as the connection is direct. However, when streaming (DLNA, YouTube), your traffic goes through the router, which can reduce speeds on other devices, especially when watching 4K video.

How to improve image quality during broadcasting?

For improved quality, ensure you're using the 5 GHz band. Also, close background apps on your smartphone to free up CPU resources for encoding the video stream. In your TV settings, you can select the "Bright" or "Game" picture mode to reduce latency.
