Modern technologies make it possible to transform your smartphone screen into a powerful multimedia control panel, displaying content on a large display. Wireless connection Connecting your Android or iOS device to an LG TV gives you wireless access to photos, video archives, and streaming services. This is especially convenient for watching high-definition movies or sharing presentations with colleagues.
The synchronization process is based on the use of a local network. Wi-Fi, which ensures stable data transfer with minimal latency. However, users often encounter configuration nuances that depend on the operating system version and TV model. In this article, we'll detail all the available methods so you can choose the most suitable one for your situation.
It's worth noting that image quality directly depends on the speed of the router and its location relative to the receivers. Signal The signal must be stable, otherwise artifacts or audio desynchronization may occur. Let's review the basic steps for preparing the equipment before setting it up.
Preparing equipment and network
Before you begin pairing your gadgets, you need to make sure that all devices are in the same information space. Router The router should work correctly, and the TV and smartphone should be connected to the same access point. If you have a dual-band router, make sure both devices are "seeing" the same frequency, although modern routers usually combine networks automatically.
⚠️ Attention: If your router is sharing a guest network, devices may be isolated from each other. In this case, direct detection of the TV by the phone will be impossible, even if both are connected to the internet.
Make sure your LG TV has the latest firmware version. Older firmware may not support new data transfer protocols or may contain security vulnerabilities. The update typically takes a few minutes and requires a stable connection.
It's also important that your smartphone has the necessary permissions to work with the local network enabled. In modern versions Android And iOS The system may ask for confirmation to search for devices on the network when you first launch the broadcast application.
Using the built-in Screen Share feature
LG TVs are equipped with native technology Screen Share, which is based on the standard MiracastThis method allows you to mirror your smartphone's screen to your TV without using additional apps, which is a huge performance boost. The image is transmitted directly, bypassing complex processing servers.
To activate the function, find the button labeled "On" on your LG TV remote control. Input or the house icon. In the signal source selection menu that opens, find and launch the application. Screen ShareA waiting-for-connection message will appear on the screen, and the TV itself will become visible for searching.
On an Android smartphone, the process may have different names depending on the manufacturer. It could be a function Smart View, Broadcast or Wireless ProjectionOnce the search is enabled, the name of your LG TV will appear in the list of available devices.
☑️ Check before connection
After selecting a TV from the list, a connection confirmation request may appear on your smartphone screen. Accept the request using the TV remote or by tapping on the mobile device's screen. From this point on, the image from your phone will be fully copied to the big screen.
Streaming via the LG TV Plus app
Official app LG TV Plus Provides advanced functionality for managing and streaming media content. Unlike simple screen mirroring, this method allows you to transfer specific files (photos, videos, music) from your phone's memory, leaving the smartphone interface free for other tasks. This is especially convenient if you need to reply to a message while watching a video.
To get started, you need to download the application from the official store. Google Play, App Store or Galaxy StoreAfter installation, launch the program and follow the on-screen instructions. The app will automatically scan the network and offer a list of available LG TVs.
When you connect for the first time, a message will appear on your TV screen. confirmation code, which you'll need to enter into the smartphone app. This is a security measure to prevent unauthorized persons from controlling your TV. Once the devices are successfully paired, the app will transform into a convenient remote control with a touchpad and keyboard.
⚠️ Attention: The Magic Remote feature in the LG TV Plus app allows you to control the cursor on the TV screen by moving your smartphone in the air. For the gyroscope to function correctly, calibration may be required each time the app is launched.
The app interface has a separate tab for your media library. Selecting a file there will play it through your TV's built-in player. This reduces the load on your smartphone's processor and saves battery life.
Connecting an iPhone via AirPlay 2
Apple technology owners can take advantage of the technology AirPlay 2, which is built into many modern LG TV models. This enables native integration of the iOS ecosystem with the TV without the need for third-party apps. Video streaming quality remains high, and latency is minimal.
Make sure your LG TV supports AirPlay 2. This information is usually found in the model specifications or in the connection settings menu. LG TVs with webOS 4.0 and later often have this feature built-in. To activate it, go to Settings and find the section Connecting to a mobile device, where you need to enable AirPlay support.
On your iPhone or iPad, open Control center (swipe down from the top right corner or from the bottom up, depending on the model). Tap the icon Screen mirroring (two intersecting rectangles). Select your LG TV from the list.
What should I do if AirPlay doesn't detect my TV?
If your TV doesn't appear in the list, try rebooting your router. Also, check if your router's antivirus software is blocking multicast protocols, which are necessary for detecting Apple devices. Sometimes, temporarily disabling your smartphone's VPN can help.
After selecting a device, a four-digit code may appear on the TV screen. Enter it on your iPhone to establish a secure connection. Your smartphone screen is now cast to the TV, and you can launch any apps, including those that don't have their own "Cast" button.
DLNA multimedia streaming
Protocol DLNA (Digital Living Network Alliance) is one of the oldest and most reliable methods of transmitting media files. It doesn't mirror the screen, but allows the TV to read files directly from the smartphone's memory or network storage. This is ideal for watching large 4K video files, as the decoding is handled by the TV's powerful processor, not the phone.
Most gallery apps and video players on Android and iOS have built-in DLNA support. Open the desired video file or photo in the default app. Look for the streaming icon, which looks like a rectangle with Wi-Fi waves in the corner (often called Cast or Broadcast).
In the list of devices that opens, select your LG TV. If your TV isn't found, make sure its settings allow access to content from mobile devices. This is often found in the "Mobile Devices" section of the TV menu. Connections -> Connection Manager -> Mobile devices.
| Parameter | Screen Share (Miracast) | DLNA | AirPlay 2 |
|---|---|---|---|
| Transmission type | Screen mirroring | File broadcast | Dubbing/Broadcasting |
| Phone addiction | High (screen on) | Low (you can turn off the screen) | Average |
| Quality | Depends on the signal | Original uncompressed | High |
| Sound | Synchronized | Synchronized | Perfect synchronization |
Using DLNA is especially useful when you need to pause a video, leave the house, or simply drain your smartphone's battery while leaving the movie playing on the big screen. The TV automatically buffers the data stream.
Troubleshooting connection issues
Despite the simplicity of setup, users may encounter difficulties. One of the most common issues is that the TV isn't visible in the list of available devices. First, check whether "AP Isolation" is enabled on your router. This setting prevents devices within the same network from communicating with each other, which prevents the TV from being detected.
Another possible cause could be an outdated network driver or DNS cache. Try a hard reboot of the router by unplugging it for 10-15 seconds. You should also try resetting the network settings on your LG TV via the menu. Settings -> Net -> Wi-Fi Connection -> Advanced Wi-Fi Settings -> Edit -> Disconnect, and then reconnect.
If you receive the "Unable to connect" or "Server busy" error when connecting, try changing the device name in your TV settings. Sometimes, old cached entries on your smartphone conflict with new settings. Remove the TV profile from the list of saved devices on your phone and try searching again.
⚠️ Attention: Antivirus software on your smartphone or PC may be blocking ports required for Miracast and DLNA protocols. If all else fails, try temporarily disabling your firewall to test this hypothesis.
If you see an image but no sound, check the audio output settings in the app you're streaming from (for example, YouTube or VLC). Sometimes the system defaults to outputting audio through your phone's speaker.
Optimizing wireless transmission quality
To get the best viewing experience, it's important to minimize latency and compression artifacts. If your router supports dual-band, connect your TV and smartphone to the network. 5 GHzThis range is less congested with neighboring networks and provides higher throughput, which is critical for high-definition video.
The router's location is also important. Walls, especially load-bearing ones with reinforcement, and household appliances (microwaves, baby monitors) can cause significant interference. Ensure there's a clear line of sight between the router and the TV, or as few obstructions as possible.
If you're using your smartphone to stream games, enable Do Not Disturb mode or Game Mode on your phone. Incoming notifications can interfere with the image or cause micro-lag in the system, which will affect the smoothness of the picture on your TV.
The Secret to Stable Streaming
If your router is old and can't handle simultaneous data transmission to your TV and phone, consider purchasing a separate access point or a mesh system. This will dramatically improve the situation in larger apartments.
Regularly clear the cache of apps used for streaming. Accumulated temporary files can slow down software performance and cause connection errors. In Android settings, this can be done via "Applications" -> "Storage" -> "Clear Cache."
Why is my LG TV not showing up in the list of devices?
The most common issue is that the devices are connected to different networks (for example, one on 2.4 GHz and one on 5 GHz with different SSIDs) or client isolation is enabled on the router. Also, check if the Screen Share app is running on the TV itself.
Is it possible to broadcast a screen without the internet?
Yes, Miracast and Screen Share don't require internet access, as the connection is established directly between devices (Wi-Fi Direct). However, DLNA and AirPlay require a local network (router), even if there's no internet access.
How to reduce audio latency during broadcasting?
Latency often occurs when using Bluetooth headphones with video streaming. Try connecting the headphones directly to the TV or using a sound system that supports aptX Low Latency. Uninstalling unnecessary apps on your smartphone can also help.
Does my old LG TV support wireless streaming?
Models prior to 2015 may not have built-in Miracast or AirPlay support. In this case, the solution is to purchase an external adapter (such as a Chromecast, Apple TV, or Miracast dongle) that plugs into the HDMI port and handles signal reception.
Is it safe to connect a smartphone to public Wi-Fi for streaming?
No, public networks (such as cafes and airports) often have isolation enabled, so streaming won't work. Furthermore, data transmission on open networks is unsecured, which can lead to personal information leakage. Use only trusted home networks.
