Modern LG TVs running the webOS platform offer users a wide range of multimedia capabilities that go far beyond simply watching broadcast channels. One of the most popular features is the ability to mirror your screen or stream content from your smartphone directly to the large display without the need for unnecessary cables. This allows you to showcase vacation photos, play videos from non-core apps, or even play mobile games with enhanced graphics on the widescreen display.
To implement wireless connection importantBoth devices must be on the same local network, ensuring stable data transfer with minimal latency. Miracast technology, built into most LG models, allows for a direct connection, while AirPlay 2 support allows iPhone owners to stream content with quality comparable to a wired connection. Understanding how these protocols work will help avoid common setup errors.
In this guide, we'll cover all the current methods for synchronizing gadgets with your TV, paying special attention to the nuances of setting up your router and mobile device operating systems. You'll learn how to activate hidden signal reception features and which manufacturer apps you might need for advanced control. Proper network setup will ensure seamless use of your home theater's multimedia capabilities.
Technical requirements and equipment preparation
Before setting up, you need to make sure your equipment meets the minimum requirements for a high-quality video stream. Most modern LG TVs released after 2014 and equipped with webOS have a built-in Wi-Fi module and support for Screen ShareHowever, older models without a built-in wireless adapter will require an external USB Wi-Fi module or a connection via a DLNA server, which may limit the functionality of simple mirroring.
A critical requirement is that the smartphone and TV be on the same subnet. This means that if your router broadcasts two networks (for example, 2.4 GHz and 5 GHz), both devices must be connected to one of them, although modern routers often combine them into a single SSID. If you're using a guest Wi-Fi network or the client isolation feature on your router, device discovery may be impossible, as these settings block local data exchange between connected devices.
⚠️ Note: Some corporate or public Wi-Fi networks (in hotels and offices) have hardware-based client isolation, making it impossible to connect your phone and TV even when entering the correct password. In such cases, using the "Hot Spot" feature on your smartphone can be a temporary solution, but it will consume your mobile data.
It's also worth checking the operating system version on your mobile device. Android version 5.0 or higher is recommended, although Android 8.0+ is better for stable operation of new codecs. iOS users should update to iOS 12.3 or later for full AirPlay 2 support without the need to install third-party software. Outdated software may not support the modern encryption protocols used by the TV.
Setting up an LG TV to receive a signal
The TV setup process begins with checking the network connection. You need to go to the settings menu and ensure that the Wi-Fi module is activated and the device is connected to the internet. To do this, press the button Settings on the remote control (gear icon), then select All settings and go to the section Net. The status should show "Connected" and the name of your wireless network.
The next step is to enable external signal reception. Depending on your webOS firmware version, the path to this setting may vary slightly. On newer models, navigate to Support, then select Screen Share (or "Mobile Device Casting"). A connection waiting window will appear on the screen, where the TV will be visible to other devices on the network. In some interface versions, this function is accessed through the input menu. Input or via the quick application launcher.
☑️ Check TV readiness
It's important to note that your privacy settings may prohibit connections from unknown devices. If your phone doesn't see your TV, check the settings in the section General -> Device management (or "List of connected devices"). Here you can allow access for new devices or remove old, conflicting connections. Sometimes resetting the list of trusted devices helps, making the TV visible to all devices within range.
Broadcasting from Android: Built-in Tools and Apps
Android smartphone owners have several ways to display video, and the method they choose often depends on the device brand. The most universal standard is the Miracast protocol, which is supported out of the box by most manufacturers. To start casting, simply pull down the notification shade and find the button. Broadcast, Smart View (Samsung), Cast or Wireless monitorOnce clicked, the system will begin searching for available displays on the local network.
When your LG TV appears in the list (usually labeled as LG webOS TV or a model such as 55UN7300), simply tap its name. A connection confirmation prompt may appear on the TV screen, which you'll need to accept using the remote. After this, the smartphone's image will be fully mirrored on the big screen, including system notifications and audio. Picture quality in this mode depends on the phone's processor and Wi-Fi speed.
For more advanced control, especially if standard tools are unstable, you can use the official application LG ThinQThis tool not only allows you to stream photos and videos from your gallery, but also use your smartphone as a touchpad remote control. After installing the app and registering your device in the menu Add a device, you can choose content to play without interrupting other tasks on your phone.
| Smartphone brand | Function name | Menu path (approximate) | Peculiarities |
|---|---|---|---|
| Samsung | Smart View | Notification shade / Settings | Multitasking support |
| Xiaomi / Redmi | Broadcast | Settings -> Connection and Sharing | Low latency in games |
| Huawei | Projection | Curtain -> Projection | Requires TV confirmation |
| Pure Android | Broadcast | Settings -> Connected devices | Basic Miracast functionality |
⚠️ Please note: When using the "Projection" or "Cast" feature, the smartphone screen may remain active, resulting in increased battery consumption and heat buildup. It is recommended to keep the device connected to a charger or reduce screen brightness during extended sessions.
Using AirPlay 2 for iPhone and iPad owners
Apple ecosystem users can take advantage of AirPlay 2 technology, which is built into LG TVs starting with 2018-2019 models (webOS 4.0 and above). This method ensures the best picture quality and minimal latency, and also allows the TV to be used as an external speaker system. No additional apps are required for connection; all functionality is native to the iOS operating system.
To start broadcasting, open Control Center on your iPhone (swipe down from the upper-right corner on models with Face ID or swipe up on models with a home button). Tap the icon Screen mirroring (two intersecting rectangles). Select your LG TV from the list that appears. If this is your first time pairing, a four-digit code will appear on the TV screen. Enter this code on your iPhone to pair the devices.
AirPlay 2 not only mirrors your screen but also streams content from specific apps (YouTube, Netflix, Apple TV+) by tapping the corresponding icon inside the player. In this case, your phone acts as a remote control, and the TV downloads video directly from the internet, saving battery life and reducing Wi-Fi bandwidth. Additionally, it supports "Photo in Frame" mode, allowing you to display content on your TV while continuing to use other apps on your smartphone.
What to do if AirPlay isn't working?
Make sure "Require code" is enabled in the AirPlay section of your TV settings. Try changing the code type to "First time" or "Every time." Also, check if AP isolation mode is enabled on your router, which blocks the connection between your Apple devices and your TV.
It's worth noting that AirPlay 2 requires a stable Wi-Fi connection. If you experience artifacts or audio interruptions, try switching your router to a less congested channel or moving closer to the access point. In some cases, rebooting the router can help, as this clears the buffer and redistributes bandwidth.
Specialized applications for multimedia
If built-in display tools don't meet your needs or the file format isn't supported by your TV system, third-party apps can help. One of the most popular solutions is TV Cast for LG WebOSThis app lets you send videos, photos, and even web pages from your computer or phone to your TV. It's especially useful for playing local video files in formats that your LG media player can't play out of the box.
Another powerful tool is the app AllConnect or BubbleUPnPThese programs operate using the DLNA/UPnP protocol and allow you to create media libraries on your phone that are accessible to your TV. Unlike simple mirroring (Miracast/AirPlay), only the data stream is transmitted, not the desktop image. This means you can turn off your phone's screen or launch another game, and the video on your TV will continue to play without interruption.
For users who want to stream content from a PC to a TV via a phone as an intermediary (or vice versa), there are bridge apps. However, the most effective scenario is installing a server app on a computer (such as Plex or Kodi) and using the phone as a remote control to select content on the LG TV. This turns the TV into a fully-fledged media center with a convenient control interface via the smartphone's touchscreen.
Solving common connection problems
Despite the technology's refinement, users may encounter situations where the phone doesn't detect the TV or the connection constantly drops. The most common cause is desynchronization of IP addresses or DNS cache. In this case, a simple reboot of the router and both devices helps. Unplug the TV's power cord for 10-15 seconds to completely drain any residual current and reboot the webOS operating system.
If the problem is low data transfer speed (video stutters or has low resolution), check the Wi-Fi channel load. Neighboring routers may be causing interference. Try switching the Wi-Fi channel to a clearer one in your router settings or, if your equipment supports it, switching to the 5 GHz band, which is less congested and provides the higher throughput needed for 4K content.
In rare cases, outdated TV firmware can cause problems. Manufacturers regularly release updates that fix network module and security protocol bugs. You can check for updates in the menu. All settings -> Support -> Software update -> Check for updatesInstalling the latest version of software often resolves compatibility issues with new versions of iOS and Android.
⚠️ Note: The menu interface and item names may vary depending on the webOS version and regional TV model. If you can't find the option you're looking for, use the settings search (the magnifying glass icon in the settings menu) or refer to the official documentation for your specific model.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone to an LG TV without a Wi-Fi router?
Yes, many LG models support Wi-Fi Direct. This feature allows the TV to create its own wireless network, which your phone connects to directly. However, data transfer speeds may be lower in this mode, and your phone's internet connection may become unavailable during the connection if it doesn't support dual networks.
Why is there no sound on the TV when connected via Wi-Fi?
This is most often due to the settings of a specific app or operating system. When mirroring (Miracast), audio should be automatic. If you're using Chromecast within apps (YouTube), check that the audio output device is selected. Also, make sure your TV isn't set to "Quiet" or low volume.
Does phone connection affect internet speed?
Using DLNA protocols (file streaming) doesn't consume internet bandwidth, as the data travels within the local network. Using AirPlay Mirroring or Miracast also consumes local bandwidth. However, if you're streaming online video, the TV will consume internet bandwidth, but it typically draws it directly from the network, not through your phone, unless your phone is using Wi-Fi.
How to disable mirroring?
To stop mirroring on Android, simply unlock the screen, open the notification panel, and tap "Disconnect" or "Disconnect." On iPhone, open Control Center again, tap the "Screen Mirroring" icon, and select "Stop Mirroring." You can also simply turn off Wi-Fi on your smartphone.
