Modern Smart TV LG devices offer users a wealth of multimedia entertainment options, but built-in apps are often insufficient for a fully immersive experience. Sharing images from a mobile device with a larger screen allows you to display photos, play videos from browsers that don't support DLNA, or even play mobile games with better graphics. Wireless connectivity is the most convenient solution in this case, eliminating the need for long HDMI cables and adapters.
The process of synchronizing a gadget and a TV is based on technologies Miracast And DIAL, which are built into the operating system webOSIt's important to understand that the quality of your video stream directly depends on the signal stability and bandwidth of your home network. If your router is located far away or the channel is overloaded by neighboring networks, delays or audio desynchronization may occur, so it's important to approach your local network setup carefully.
In this article, we'll cover the detailed steps for Android and iOS devices, as the setup approaches differ significantly between these ecosystems. You'll learn how to activate hidden signal reception features, which apps might be needed for older TV models, and how to troubleshoot common connection errors. The key condition for successful pairing is that both devices are on the same Wi-Fi network (the same subnet segment).
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your equipment is technically capable of supporting wireless streaming. Most LG TVs released after 2013 and bearing the logo Smart TV, are equipped with a built-in Wi-Fi module and support the Miracast standard. However, on older models running NetCast 4.0 or earlier versions of webOS, functionality may be limited or require additional software.
Smartphone owners should also check their operating system version. Android devices should preferably have version 4.2 or higher, although Android 8.0+ is recommended for stable operation of modern codecs. iPhone users will need iOS 9.0 or later to use AirPlay 2, which is natively supported by new LG models. If your TV doesn't have built-in Wi-Fi but does have a USB port, you can try using a dedicated Wi-Fi adapter, although this is a less reliable option.
⚠️ Important: Make sure "Client Isolation" is not enabled on your router. This security setting prevents devices connected to your Wi-Fi network from communicating with each other, making it impossible for your phone to detect your TV.
It's also worth paying attention to the wireless network frequency range. For high-definition video streaming (Full HD or 4K), it's highly recommended to use the frequency range 5 GHzIt provides higher data transfer rates and is less susceptible to interference from microwave ovens and Bluetooth devices that actively use the 2.4 GHz band.
Setting up an LG TV to receive a signal
The first step is to properly configure the TV itself. Depending on the version of the operating system installed, webOSThe menu and item names may differ slightly, but the general procedure remains the same. You need to activate the mode that makes the TV visible to external devices.
LG remote controls often have a special button with the inscription Input or the house icon. Clicking it will take you to the signal source selection menu. Here you need to find the app Screen Share (on new models) or Smart Share (on older devices). Launching this app puts the TV into connection standby mode.
If you are using the latest version of webOS (3.0 and above), you can configure it through the main menu:
- 📺 Press the settings button (gear) on the remote control.
- 📡 Go to the section
All settings→Connection. - 📶 Select an item
Connecting to a mobile deviceorScreen Share. - ✅ Make sure the "On" status is active and remember the TV name that appears on the screen.
In some cases, the system may ask for connection confirmation each time a new device is connected. This is a security feature that prevents unauthorized access to your screen. You can also change the TV name in the settings to make it more recognizable, for example, "LG_LivingRoom" instead of the standard character set.
☑️ TV is ready for connection
Connecting an Android smartphone to an LG TV
The Android ecosystem offers several ways to mirror images, and the specific method you choose depends on your smartphone's manufacturer. The underlying technology is called Miracast, but different brands implement it differently. For example, on Samsung this feature is called Smart View, on Xiaomi it's called Broadcast, and on stock Android devices it's called Broadcast or Cast.
First, make sure Wi-Fi is turned on on your phone. Then, pull down the notification shade to open the quick access panel. Look for the icon corresponding to your device. If you can't find it right away, you may need to expand the full list of toggles or search for "Cast" in Settings.
Once the search function is activated, your phone will begin scanning for available devices on the network. When your LG TV's name appears in the list, tap it. You may see a connection permission prompt on the TV screen—confirm it using the remote. Your smartphone's screen will then be mirrored on the TV.
If you can't connect using standard means, you can use the official application LG TV Plus or LG ThinQThese programs not only allow you to stream media files but also use your phone as a remote control. To view photos and videos using the file manager, simply select the file, click the "Stream" button, and select the target DLNA device.
What to do if the phone doesn’t see the TV?
If the search yields no results, try rebooting your router. Sometimes temporarily disabling mobile internet (4G/5G) on your smartphone to force it to use only Wi-Fi helps. Also, check if your router has any MAC address restrictions.
Stream from iPhone and iPad (AirPlay)
Apple device owners are in luck, as LG officially supports the technology. AirPlay 2 On most modern TV models (starting from 2018-2019). This provides a more stable connection and better picture quality compared to Miracast, and also allows you to stream audio even when the iPhone screen is off.
The connection process is extremely simple and doesn't require installing any additional apps. Open the Control Center on your device (swipe down from the upper-right corner on newer models or swipe up on older models). Tap the "Screen Mirroring" icon (two rectangles).
Select your LG TV from the list that appears. If this is your first connection, a four-digit code will appear on the TV screen. Enter this code on your iPhone to confirm the pairing. Your phone's screen will then be mirrored on the TV.
To stream videos from apps like YouTube, Netflix, or Kinopoisk, you don't need to use the system's "Screen Mirroring" feature. Simply tap the icon Cast (rectangle with waves) inside the video player and select the TV. In this case, the phone will act as a remote control, and the TV will download videos directly from the internet, saving battery life.
Using specialized applications
The built-in tools don't always work perfectly, especially if you have an older LG TV or a non-standard smartphone. In such cases, third-party apps that use the DLNA protocol or their own data transfer algorithms come to the rescue. They often offer more flexible codec and buffering settings.
One of the most popular solutions is the application TV Cast for LG (available for iOS and Android). It allows you to cast web browser content, including videos that don't have a built-in Cast button. It works simply: open the app's built-in browser, navigate to the website with the video, and start playback.
Another powerful tool is the app BubbleUPnP for Android. It can find virtually any DLNA renderer online. It can stream local files stored on your phone's memory, as well as streaming video. The app supports subtitles and various audio codecs, making it indispensable for watching movies from your home library.
| Application | Platform | Broadcast type | Peculiarities |
|---|---|---|---|
| LG ThinQ | Android / iOS | Media / Remote | Official software, control of TV functions |
| TV Cast for LG | Android / iOS | Web pages | Stream any video from your browser |
| BubbleUPnP | Android | DLNA / Local Files | Support for a wide range of codec formats |
| Web Video Caster | Android / iOS | Web pages | Convenient download of subtitles |
Some may add watermarks in the free version or have session time limits. Before installing, read reviews carefully to avoid programs with intrusive ads.
Diagnosing problems and troubleshooting errors
Even with proper setup, issues can still occur. The most common issue is that the TV doesn't appear in the list of available devices. This is often resolved by simply rebooting the router, as it may have frozen and stopped routing packets between devices correctly.
If you have a connection but the picture is choppy or jerky, try reducing the network load. Disable downloads on your PC or tablet, if applicable. You can also try changing the Wi-Fi channel to a less congested one in your router settings using network analyzers.
Another common issue is audio and video desynchronization. This is typical for Miracast technology when the signal is weak. In your TV settings, you may sometimes find a "Game Mode" or "PC Mode" option that reduces input lag, which can help smooth out the audio stream.
⚠️ Please note: The interfaces of webOS and mobile operating systems (Android/iOS) are updated regularly. The location of menu items or function names may differ from those described in the instructions. Always refer to the latest manuals on the manufacturer's official website.
If nothing helps, try resetting the network settings on your TV. To do this, go to Settings → Net → Wi-Fi and select "Disconnect," then reconnect by entering your password. A full factory reset of the TV can sometimes help, but this is a last resort and requires re-authorization for all services.
Frequently Asked Questions (FAQ)
