Modern technology allows you to transform ordinary content viewing into a true cinematic experience right in your home. Many users wonder how to mirror their phone screen to their TV via LG WiFi to enjoy photos, videos, or games on a larger screen. This process doesn't require complex cables or additional equipment, as long as both devices support wireless data transfer standards.
Technology Screen Share Miracast is built into most modern LG models and runs on the webOS operating system. For a successful connection, it's crucial that your smartphone and TV are on the same local network. If your router uses a 5 GHz internet connection, video streaming speeds will be significantly higher and latency will be minimal.
In this guide, we'll cover all the setup details, from basic operating principles to troubleshooting specific connection errors. You'll learn the differences between streaming via built-in Android features and using proprietary LG apps. We'll also cover the specifics of working with iOS devices, as the process has its own unique challenges.
How Wireless Streaming Works on LG
The basis for image transmission is the protocol Miracast, which allows for direct WiFi connections between devices without a router, or the DLNA standard for media content. LG TVs implement this feature via an app. Screen Share, which activates the external device discovery mode. Unlike Chromecast, which requires Google services, LG's native feature operates at a deeper system level.
When a broadcast is launched, the smartphone encodes the video stream in real time and sends it over the network. The TV decodes the signal and displays the image. It's important to understand that image quality It directly depends on the WiFi signal strength and channel load. If there are many neighboring networks nearby, artifacts or audio desynchronization may occur.
There are two main modes: mirroring the entire screen and casting specific content from apps. The first option completely mirrors what you see on your smartphone's display, including notifications and the control panel. The second option allows you to use your phone as a remote control while the TV plays video, saving battery life.
⚠️ Attention: When using mirroring mode, messaging notifications and incoming calls will be displayed on the TV screen. It is recommended to enable "Do Not Disturb" mode on your smartphone beforehand.
Some older router models may not correctly process multicast traffic required for device discovery. In such cases, you may need to configure client isolation or change the broadcast channel in the router's admin panel.
Preparing equipment and network
Before you begin setup, you need to ensure your infrastructure is ready to handle heavy video streaming. Ideally, you should use a dual-band router operating in the 5 GHz band. This will provide sufficient bandwidth to transmit high-resolution video. 1920×1080 or 4K no buffering.
Make sure your LG TV has the latest firmware version. Manufacturers regularly release updates that improve WiFi module stability and compatibility with new versions of Android and iOS. You can update through the menu. Settings → All settings → General → About TV → Check for updates.
- 📶 Make sure your phone and TV are connected to the same WiFi network (SSID name must match).
- 🔄 Restart your router if your network is unstable or devices can't see each other.
- 📱 Geolocation and Bluetooth must be enabled on your phone, as they are often used for initial device detection.
- 🔋 Charge your smartphone to at least 40%, as active data transfer quickly drains energy.
If you're using a guest WiFi network at a hotel or office, broadcasting may be blocked by the network administrator's security settings. At home, ensure that the "AP Client Isolation" feature isn't enabled on your router, which prevents devices within the network from exchanging data.
☑️ Check before connection
Stream from Android using built-in features
Android smartphone owners can use the standard casting feature, which is called differently in different operating systems. On Samsung, it's Smart View, on Xiaomi — Broadcast, on Motorola and pure Android - ScreencastingTo launch it, you usually just need to open the notification shade and find the corresponding icon.
Once the feature is activated, your phone will begin searching for available devices. Your LG TV should appear in the list. When you select a device, a connection confirmation prompt may appear on the TV screen. Use the remote to press OK or Accept.
If the automatic search doesn't yield results, you can try adding the device manually through the settings. The path may vary: Settings → Connected devices → BroadcastHere, you sometimes need to press the menu button (three dots) and select "Enable Miracast" or "Search for devices."
| Smartphone brand | Function name | Where to find |
|---|---|---|
| Samsung | Smart View | Notification shade |
| Xiaomi / Redmi | Broadcast | Settings / Curtain |
| Huawei / Honor | Projection | Notification shade |
| Motorola / Pixel | Broadcast | Settings / Curtain |
In some cases, especially on older versions of Android, you may be required to enter a PIN code displayed on your TV screen. This is a standard security procedure to prevent unauthorized access to your screen.
What to do if the phone doesn’t see the TV?
If the search yields no results, try launching the Screen Share app on the LG TV itself before searching on your phone. Sometimes the TV goes into sleep mode and becomes unavailable to the network. Temporarily disabling mobile data (4G/5G) on your smartphone to force traffic over WiFi also helps.
Using the LG TV Plus app
Official app LG TV Plus (formerly LG Remote) offers advanced control and streaming capabilities. It's available for Android and iOS. After installation and pairing with your TV (enter the code that appears on the TV screen), you can access the photo and video sharing feature from your gallery.
To launch, open the app and go to the "Media" or "Gallery" section. Once you've selected the desired photo or video, tap the streaming icon (the rectangle with a WiFi signal). The content will open on your TV screen, and you can use your smartphone as a remote control.
The advantage of this method is that it requires less connection stability than mirroring the entire screen. The TV downloads the file over the network, offloading the smartphone's processor. However, it's not possible to stream game interfaces or browsers this way.
⚠️ Attention: The LG TV Plus app may not support streaming protected content (DRM) from some streaming services. For Netflix or YouTube, it's better to use the built-in Cast features within the apps themselves.
You can change the transmitted image quality in the app settings. If you notice stuttering in your high-resolution photo slideshow, try lowering the quality in the app settings to HD instead of 4K.
Stream from iPhone and iPad (AirPlay 2)
Apple technology owners can use the technology AirPlay 2, which is supported by most modern LG TVs (2019 and newer models, as well as some earlier models after an update). This ensures the best picture quality and minimal latency.
To start casting, open Control Center on your iPhone (swipe down from the upper-right corner or swipe up on older models). Tap the "Screen Mirroring" button (two rectangles). Select your LG TV from the list.
If your TV doesn't show up, make sure AirPlay support is enabled in your LG settings. Here's how to set it up: Settings → Connection → AirPlay and HomeKitHere you can also set up a code requirement upon connection or add the device to the trusted list.
- 🍎 AirPlay 2 allows you to stream audio separately when the TV is turned off, using it as an AirPlay speaker.
- 🎮 The feature is great for gaming, providing low Input Lag compared to Miracast.
- 🔒 When you first connect, a 4-digit code will appear on the TV screen, which you need to enter on your iPhone.
It's important to note that when casting via AirPlay, the iPhone interface automatically rotates to landscape mode if the content requires it. If this doesn't happen, check to see if the screen orientation is locked in Control Center.
Solution and connection errors
Despite the simplicity of the technology, users often encounter problems. The most common one is "Device not found." In 90% of cases, this is resolved by checking that the phone and TV are connected to the same network. Sometimes, routers create two networks with similar names (for example, "Home" and "Home_Guest"), and devices end up in different virtual rooms.
Another common issue is audio and video desynchronization. This is typical of congested WiFi channels. Try switching your router to a different channel or moving the TV and router closer together for a test. Disabling Bluetooth on your phone, unless it's used for the remote control, can also help, as the signals can interfere.
If the image is choppy or low-resolution, check the resolution settings on your phone. Some smartphone models automatically reduce quality when connected to an external display to save data. You can try changing the performance priority in the engineering menu or developer settings.
⚠️ Attention: The LG TV menu interface may vary depending on the webOS version (3.0, 4.0, 5.0, 6.0, and higher). If you can't find the item described, use the settings search (magnifying glass in the menu) or consult the official manual for your specific model.
In rare cases, the problem lies with your antivirus or firewall software on your smartphone, which is blocking local connections. Try temporarily disabling your network protection and testing the stream.
Secret Method to Restart DLNA Service
If all else fails, go to your TV's network settings, select "Advanced WiFi Settings" (if available), or simply change the device name (LG TV) to something else. This will force a restart of the network discovery services.
