Modern multimedia capabilities make it possible to transform any TV into a fully-fledged home theater center. It's often more convenient to watch a movie on your smartphone but then view it on a larger screen to enjoy the best picture and sound quality. LG with support Smart TV can do this without any extra wires, using only the home network.
For successful signal transmission, it is critical that both devices are on the same local network. This means that your smartphone is based on Android The TV and the TV must be connected to the same router. If you're using mobile data on your phone, streaming won't work, so check your settings first. WiFi.
There are several proven ways to accomplish this task, from built-in system functions to specialized apps. The specific method you choose depends on your TV model and operating system version. WebOS or Android TV, as well as the type of content being played. In this article, we'll cover all the current options so you can choose the most convenient one.
⚠️ Note: Wireless streaming quality directly depends on the speed and stability of your WiFi router. If you experience lag or choppiness while watching, try moving the router closer to your TV or switching to the 5 GHz band.
Preparing equipment and checking the network
Before you begin configuring the software, you need to ensure that your hardware is ready. A basic requirement is a working router and functioning wireless modules on both devices. Make sure your router supports the following standards: 802.11n or newer, as older protocols may not be able to handle high-definition video streaming.
Check if the WiFi function is enabled on the TV itself. LGOn some models, it may be disabled by default or in sleep mode. To activate it, press the settings button on the remote control and go to the network menu. Here you will see a list of available access points.
- 📶 Make sure your phone and TV are connected to the same network (SSID), especially if you have a dual-band router with the same names for 2.4 and 5 GHz.
- 🔌 Restart your router if the connection is unstable—this often solves problems with device visibility on the local network.
- 📱 Disable the "Data Saver" mode on your smartphone, as it may block data transfer to external devices.
It's important to understand the difference between a simple internet connection and local interaction. Even if the internet connection is disabled on the router, file or screen sharing over the local network will work as long as both devices can see each other. However, for streaming online video (YouTube, Netflix), internet access is required.
Using Screen Share (Miracast)
The fastest way to display an image is to use technology Miracast, which is on TV LG Often called Screen Share, this method allows you to mirror your smartphone's entire screen to your TV in real time. It's ideal for sharing photos, presentations, or DRM-free videos.

⚠️ Note: Some content-protected apps (such as Netflix or Kinopoisk HD) may show a black screen instead of video when using Miracast due to HDCP copyright protection policy.
Broadcasting via built-in YouTube apps and online services
If you want to watch videos from popular video services, using the "Cast" feature within the apps themselves is the best solution. Unlike screen mirroring, your phone acts only as a remote control, and the video is downloaded directly from the internet by the TV. This ensures maximum picture quality and eliminates lag.
Open the app YouTube On your smartphone, find the streaming icon (the rectangle with waves in the corner). Tap it and select your TV. LG from the list of available devices. The video will start playing on your TV, and you can continue using your phone for other tasks or even turn it off without interrupting playback.
A similar principle works in many other applications such as Netflix, IVi, Okko and browser Google ChromeIn the Chrome browser, you can even broadcast the contents of individual tabs or your entire computer screen if it's connected to the same network.

Make sure mobile device connectivity is enabled on your TV. Go to Settings → Connection → Mobile Device Connection and ensure the toggle is enabled. Also, check to see if your phone's antivirus software is blocking the local network.
Streaming via DLNA and third-party players
For users who store a collection of high-quality movies on a phone or network-attached storage (NAS), the best solution is to use the protocol DLNA. Televisions LG support this technology out of the box via an app Smart Share (or simply "Photos & Videos" in newer versions of WebOS).
To use this, you will need a third-party player on Android, such as VLC for Android or BubbleUPnPThese apps can find DLNA renderers (like your TV) and send a video stream to them. Open the video file in the player, click the "Cast" or "Broadcast" button, and select your LG TV.
Unlike Miracast, this method involves transcoding or direct streaming, reducing the load on the phone's processor. The TV decodes the video itself, using its own hardware. This allows you to watch 4K movies without stuttering, provided your WiFi speed allows.
You may need to allow access for unknown devices in your TV settings. When you first try to connect, you may see a confirmation prompt on the TV screen. Select "Allow" or "Accept."

Solving common connection problems
Despite the simplicity of the technology, users may encounter difficulties. One common issue is that the TV isn't visible in the list of available devices. In 90% of cases, this is due to router settings, specifically AP Isolation. When enabled, this prevents Wi-Fi devices from communicating with each other.
Another possible cause is firewall or antivirus settings on your smartphone that are blocking local connections. Try temporarily disabling them to test. Also, make sure your TV is running the latest firmware version, as older versions may have compatibility issues with newer versions of Android.
If the video plays but the audio only comes from your phone, check the audio output settings in the player app itself or in the Android notification shade. Sometimes you need to manually switch the audio output to an external device.
Recommended actions in case of failures:1. Reboot the router (unplug it from the power outlet for 10 seconds).
2. Forget the WiFi network on your phone and reconnect.
3. Reset the network settings on the TV (Settings → Network → Advanced Wi-Fi Settings → Edit → Reset).
4. Check the date and time on both devices (they must match).
In rare cases, resetting the network settings on the TV itself to factory defaults can help. This won't delete your apps, but it will clear the network configurations, which often resolves network visibility issues.
Why does video lag even with perfect internet connection?
The problem may be that your neighbors are congesting your WiFi channel. Try changing the broadcast channel in your router settings or switching your TV to the 5 GHz network, which is less congested.
Comparison of methods and final recommendations
The connection method you choose depends on your specific needs. If you need to quickly share photos with friends, use Screen ShareFor comfortable viewing of online movies, the built-in "Streaming" feature in apps is best.
