Modern LG TVs running the webOS operating system offer users a wide range of multimedia entertainment options, but there's often a need to display content stored directly on your smartphone on the big screen. Wireless Wi-Fi has become the de facto standard, allowing you to eliminate unnecessary cables and enjoy photos, videos, and games on displays 55 inches or larger. While synchronizing devices seems simple, it often involves technical nuances related to operating system versions, router settings, and data transfer protocols.
In this article we will examine in detail all the available methods. image broadcasts from mobile devices to LG TVs, paying special attention to system requirements and hidden network settings. You'll learn how to set it up correctly. Miracast And DLNA, what the difference is between these technologies, and why your phone might not see your TV in the list of available devices. We'll cover both standard Android and iOS features, as well as specialized LG apps that expand on the basic functionality.
Understanding how a local network works is key to a successful connection. If your devices are on different subnets or have router-level restrictions, a direct connection will be impossible, regardless of the method you choose. Next, we'll cover practical steps to help you set up a stable, high-definition video stream without lag or compression artifacts.
Technical requirements and equipment preparation
Before setting up, you need to ensure that your equipment meets the minimum technical requirements for wireless video streaming. The key requirement is a Wi-Fi module in both devices and support for wireless communication standards that allow for the transmission of heavy media content. Most modern LG models released after 2013 already have built-in support for this technology. Smart Share, which is based on the DLNA protocol.
It's critical that both your smartphone and TV are connected to the same wireless network. This means they must receive IP addresses from the same router and be on the same network segment. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks, make sure both devices are connected to the same band, as some older TV models may not "see" devices in adjacent bands due to client isolation settings.
⚠️ Note: When using a guest Wi-Fi network (Guest Network) on a router, a direct connection between your phone and TV is often blocked by the router's security settings. For successful syncing, use your main home network.
It's also worth checking your smartphone's operating system version. Android devices are recommended to have version 4.2 or higher for full functionality. Wireless DisplayiPhone owners will need iOS 9.0 or later to use AirPlay 2, which is supported by newer LG models. Make sure your TV software is updated to the latest version via the menu. Settings → All settings → General → About TV → Check for updates.
Using the built-in Screen Share feature on LG TVs
The most universal way, which does not require installing additional software on your smartphone, is to use the built-in function Screen ShareThis technology is based on the Miracast standard and allows you to mirror your mobile device's screen to your TV in real time. To get started, you need to activate the signal reception mode on your LG TV.
On the remote control, find the button that says Input or the house icon to open the source selection menu. From the list of available inputs, select Screen Share or Device ConnectorA connection waiting window will appear on the screen, displaying your TV's name, which you can search for on your smartphone. On some webOS models, you may first need to launch the Connection Manager app from the main menu.
☑️ Check before connection
Now let's move on to your smartphone settings. On Android devices, this feature may have different names depending on the manufacturer: "Cast," "Smart View," "Wireless Display," or "Project." After enabling the search for available displays, your LG TV should appear in the list. Tap it to establish a connection.
If the connection is successful, the image from your phone's screen will appear on the TV. It's important to understand that in this mode, the phone and TV screens are synchronized: any notifications, incoming calls, or user actions will be visible on the big screen. To stop broadcasting, simply press the "Stop" button on your phone or switch the signal source on your LG remote.
Connecting Android Smartphones: Nuances and Solutions
Android devices offer several connection options, each with its own features. In addition to the standard Miracast, many LG TV manufacturers support the technology. Google Cast (Chromecast built-in), which allows you to stream content from applications directly, without loading the phone's processor by duplicating the entire screen.
To use Google Cast, make sure you have the Google Home app or the corresponding Google Play services installed on your smartphone. Open an app that supports casting (such as YouTube, Netflix, or the Chrome browser) and look for the rectangle icon with waves in the corner. Tap it to see a list of available devices. Select your LG TV from the list.
- 📱 Live broadcast: The video is played by the TV itself, the phone acts only as a remote control, which saves battery power.
- 🖥️ Screen mirroring: Full image copy, suitable for presentations, games and applications that do not support Cast.
- 🎮 Game mode: Some LG models have a special Game Optimizer mode that reduces input lag when connected via Wi-Fi.
- 🔊 Sound transmission: When mirroring your screen, the sound is also transmitted to your TV's audio system, allowing you to use it as external speakers.
Samsung smartphone owners should pay attention to the function Smart View, which is optimized for TVs from various brands, including LG. In the quick settings menu of the notification shade, find the Smart View icon. After selecting the TV, you may be asked to confirm the connection on the TV screen using the Magic Remote.
What to do if the phone doesn’t see the TV?
If searching for devices doesn't yield results, try rebooting your router. Sometimes temporarily disabling mobile internet (3G/4G) on your smartphone to force data traffic to the Wi-Fi module helps. Also, check if "AP Isolation" mode is enabled on your router, which prevents devices within the network from seeing each other.
It's worth noting that image quality when mirroring your screen directly depends on the strength of your Wi-Fi signal. If the router is located far away or the signal is clogged by neighboring networks, you may experience choppy audio or audio desync. In such cases, it's recommended to move the router closer to the TV or use a wired connection for the TV itself, if possible.
Stream from iPhone and iPad (AirPlay 2)
For Apple device owners, the process of connecting to LG TVs has become significantly easier with the introduction of protocol support AirPlay 2 to new TV models (starting with webOS 4.5 and above). This allows you to stream videos, photos, and music, as well as mirror your screen without the need for additional Apple TV boxes.
To start casting, open Control Center on your iPhone or iPad (swipe down from the upper-right corner on newer models or swipe up on models with a Home button). Tap the "Screen Mirroring" button (the two rectangles). Select your LG TV from the list that appears. If this is your first time casting, a code may appear on your TV screen that you'll need to enter on your iPhone to confirm pairing.
AirPlay settings on your LG TV can be found in the menu Settings → Connection → AirPlay and HomeKitHere you can change the device name that your iPhone will see, set up a passcode requirement (always, first time connected, or never), and even add the TV to the iOS Home app for control via Siri.
It's important to note that AirPlay 2 allows you to stream content from apps that support it. If you want to share the entire screen (for example, to demonstrate an app), you can use the "Screen Mirroring" feature, which creates a real-time video stream. This requires a more stable connection than simply streaming a video file.
LG TV Plus app as an alternative method
Official app LG TV Plus (formerly known as LG Remote) provides another level of interaction between your smartphone and TV. While its primary function is controlling the TV from your phone, it also allows you to stream media files. This is especially convenient if standard protocols are unreliable or you need to stream files in a specific format.
After installing the app on your smartphone and pairing it with your TV (a code will appear on the TV screen), go to the "Media" or "Gallery" section. Select the photos or videos you want to share and press the "Stream" button. The app will automatically convert the stream to a format compatible with your TV and send it for playback.
| Characteristic | Screen Share (Miracast) | LG TV Plus App | AirPlay 2 / Cast |
|---|---|---|---|
| Transmission type | Screen mirroring | File transfer | Streaming |
| Phone addiction | High (screen should be lit) | Average | Low (TV plays itself) |
| Image quality | Depends on the signal | Original file | Adaptive (up to 4K) |
| iOS support | No (no third-party apps) | Yes | Native |
The app also allows you to create playlists and manage your playback queue, which is impossible with simple screen mirroring. This makes it convenient for sharing photo albums or viewing a series of videos stored on your phone's memory.
