The specific method you choose depends on your phone's operating system (Android or iOS) and the version of software installed on the TV. The most stable performance is achieved when both the phone and TV are connected to the same 5GHz Wi-Fi access point.
In this guide, we'll take a detailed look at all available syncing options, from built-in streaming features to specialized apps. You'll learn how to avoid image lag, which file formats are supported out of the box, and what to do if devices can't see each other on the network. Let's set up the perfect home theater.
Preparatory stage and network testing
Before you begin configuring software interfaces, you need to ensure your hardware is physically ready for use. A stable connection is a basic requirement for any wireless data transfer technology. Make sure your router is turned on and broadcasting a signal, and your TV is ready to use. LG already authorized on this network.
A common mistake users make is connecting devices to different router frequency bands. If your router is distributing two networks (for example, Home_WiFi_2.4 And Home_WiFi_5G), make sure both devices are connected to the same frequency. Separating frequencies can create a virtual barrier, preventing device discovery protocols from working correctly.
It is also worth checking if the function is enabled Smart Share or a similar option in the TV's settings. On some older models, this feature must be activated manually through the network menu. Without it, the TV will simply receive an internet signal but will not be able to act as a media receiver.
⚠️ Note: If you have a dual-band router, try switching your phone and TV to the 5 GHz band for 4K video streaming to avoid image stuttering.
Checking your TV's firmware version is another important step. Manufacturers regularly release updates that improve compatibility with new standards. Miracast And AirPlay 2Go to the settings menu and check for system updates to rule out software errors.

Stream content via LG TV Plus and Smart View
Company LG offers its own application LG TV Plus, which turns your smartphone into an advanced remote control and allows you to stream media files. Unlike full screen cloning, you select a specific file (photo, video, music) from your phone's memory and send it to your TV for playback.
This method is less demanding on the phone's processor resources, since the device only acts as a controller, and the TV itself handles video decoding. The application is available for download in Google Play And App StoreAfter installation and pairing with the TV (the code will appear on the TV screen), access to the phone's file system is opened.

Connecting iPhone and iPad (AirPlay 2)
For equipment owners Apple luckiest of all: modern televisions LG (starting with 2019 models and newer) have built-in support for the technology AirPlay 2This means that no additional applications are required to connect—everything works natively through the system. iOS.

| Characteristic | Android (Miracast) | iPhone (AirPlay 2) | LG TV Plus app |
|---|---|---|---|
| Transmission type | Screen cloning | Cloning / Video | Media files only |
| Delay | Average | Minimum | Absent |
| Battery consumption | High | Average | Short |
| Sound | Broadcast on TV | Broadcast on TV | Broadcast on TV |

View photos and videos via DLNA
Technology DLNA (Digital Living Network Alliance) is the de facto standard for home media networking. It allows you to share media files between devices without screen cloning. TV LG sees the phone as an external storage device or media server.
To implement this method, a server application must be installed on the phone (for example, BubbleUPnP, VLC or the built-in "Broadcast" function in the gallery). After launching the server in the application, the TV in the section Input or "Media" will detect a new device.
The advantage of DLNA is that you can start a video on your phone, switch the source on your TV, and playback will go directly from your phone to the TV, offloading the smartphone's processor. You can even turn off your phone's screen, and the video will continue playing.

Troubleshooting connection issues and errors
Despite the technology's maturity, users often encounter situations where their phone can't see their TV or the connection constantly drops. The most common cause is a disconnect between devices due to power-saving settings on the router or the phone's antivirus software.
If the devices can't find each other, try rebooting the router. Resetting the network settings on your phone or deleting the old TV connection profile from the Wi-Fi list and reconnecting often helps. Also, check if your router is set to "AP Client Isolation," which prevents devices on the same network from seeing each other.
If you see a video but no sound, check the audio output settings in the app you're streaming through. Sometimes the default audio remains on your phone and needs to be manually switched to the output device. LG TV.

- 🛡️ Check your smartphone's firewall and antivirus settings.
- 📶 Make sure the Wi-Fi signal is strong enough where the TV is located.
- 🗑️ Delete old pairing profiles in Bluetooth and Wi-Fi settings.
If all else fails, the problem may be due to outdated software. In this case, you should contact the manufacturer's support team or check forums where bugs specific to your specific TV model are discussed.
