Instructions: Connecting an Android smartphone
Android device owners have several connection options. The most versatile is using the "Cast" or "Smart View" feature built into the operating system. This method doesn't require installing additional apps and works via the Miracast protocol, which is often based on Wi-Fi Direct technology.
Pull down the notification shade and look for the "Cast," "Smart View," or "Connect to a wireless display" icon. Your phone will begin searching for available devices. Your LG TV should appear in the list. Tap it to begin pairing.
☑️ Android Connection Checklist
If the automatic search does not yield results, you can use the proprietary application LG TV PlusIt not only allows you to mirror your screen but also control your TV as a remote. After installing the app, run a network scan. The app will automatically prompt you to connect to the detected TV.
⚠️ Please note: When using the "Screen Casting" feature, there may be a slight delay in the image transmission. This is unnoticeable for viewing photos, but in fast-paced games, the lag may be 1-2 seconds.
You can use DLNA to transfer specific files (photos, videos, music). Open your gallery or player, select the file, click the "Share" button or the "Cast" icon, and select your LG TV from the list of renderers. In this case, your phone acts as a controller, and the TV plays the file automatically.
Connecting iPhone and iPad (iOS)
Apple ecosystem users may find that the native AirPlay feature is not supported by all LG models. However, if your TV is equipped with the system WebOS 4.0 AirPlay 2 support is built-in for devices running Android 10 and above. Otherwise, a third-party solution is required.
Make sure your TV and iPhone are on the same Wi-Fi network (this is a requirement for AirPlay). Open Control Center on your smartphone (swipe down from the upper-right corner or up from the bottom). Tap the Screen Mirroring icon (two rectangles).
Select your LG TV from the list of available devices. If this is your first connection, a 4-digit code will appear on the TV screen. Enter it on your iPhone to confirm pairing. Your smartphone's screen will then be fully displayed on the TV.
- 🍎 For older LG models (without AirPlay), use the app Replica or TV Cast for LG.
- 📡 Make sure that the "AP Isolation" feature, which prevents devices from seeing each other, is not enabled on your router.
- 🎞️ The video format must be supported by the TV, otherwise only images without sound may be broadcast.
Transmission quality depends on signal strength. If the picture is broken up into blocks, move closer to the router or TV. AirPlay requires a stable communication channel, as it transmits a video stream in real time with a high bit rate.
Using the LG TV Plus app
Official app LG TV Plus is the most stable way to manage content. It is available on Google Play and the App Store. The program allows you to implement functions DLNA And Wi-Fi Direct in a single interface, simplifying file selection.
After installation, launch the app. It will automatically find your TV on the network. If the devices can't see each other, check your router's firewall settings. The app acts as a media server, allowing you to select photos from your gallery and display them on the big screen in high resolution.
The app interface features a "Broadcast" or "Project" tab. Here, you can choose screen mirroring or individual file transfer. The advantage of this method is the ability to create playlists and manage the playback queue directly from your smartphone.
The app also allows you to stream files in certain formats that your TV's built-in player may not understand. In this case, it transcodes files on the fly or streams them directly, expanding compatibility with various codecs.
Solution and troubleshooting
Even with proper setup, issues may still occur. Most often, the problem stems from an IP address conflict or a temporary network service outage. If the TV stops detecting your phone, try restarting both devices. This resets the network settings cache.
