Modern televisions LG Smart TV They offer users a wealth of multimedia capabilities, transforming the living room into a full-fledged cinema. However, sometimes the built-in functionality isn't enough, and you need to display content from your smartphone on the big screen—be it photos from a family celebration, a presentation, or just a YouTube video. Wireless connection via Wi-Fi is the most convenient and popular way to implement this task, as it eliminates unnecessary wires and distance restrictions.
Syncing your mobile device and TV may seem complicated at first glance, but it only takes a few minutes with the right setup. In this article, we'll cover all the current connection methods in detail, including standard protocols. Miracast And AirPlay 2, as well as specialized apps from the manufacturer. You'll learn how to set up a network, choose the optimal broadcast method, and what to do if devices can't see each other.
It's important to understand that connection quality directly depends on the stability of your home network and software version. Before starting setup, make sure both devices are working properly and have access to the router. We'll cover the nuances for different operating systems. Android And iOS, since the algorithms of actions in them differ significantly.
Preparing equipment and network
The foundation of a successful connection is a properly organized local network. The first and most critical condition is the proximity of the smartphone and TV. LG On the same subnet. This means both devices must be connected to the same router. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks, it's best to have both devices connected to the same frequency, although modern routers often have the ability to correctly route traffic between bands.
Check the software version on your TV, as older firmware may not support new data transfer protocols or have vulnerabilities in the module. Wi-FiTo check for updates, go to your TV's settings menu, usually this path is Settings → All settings → General → About TV → Check for updatesHaving up-to-date software ensures compatibility with the latest versions of mobile applications and operating systems.
⚠️ Attention: Some corporate or guest Wi-Fi networks have client isolation, which prevents devices from seeing each other. Under these conditions, wireless broadcasting won't work, even if both devices are connected to the same access point.
It's also worth paying attention to signal strength. If the TV is located far from the router, the video streaming speed may not be sufficient to display high-resolution images, which will result in delays or artifacts. Ideally, the distance between the router and Smart TV should not exceed 10-15 meters if there are walls.
Using the built-in Screen Share (Miracast) feature
The most versatile way to mirror your Android smartphone's screen to your TV LG - this is technology Miracast, which LG implemented in the app Screen ShareThis method doesn't require installing any additional software on your TV and works on most modern models. You just need to launch the app on your TV. Screen Share, which is usually found in the recommended list or in the "More" category on the home screen.
After launching the app, the device's name will appear on the TV screen, waiting for a connection. On an Android smartphone, the steps may vary slightly depending on the manufacturer's operating system, but the general principle is the same. You need to find the wireless projector function. It's often hidden in the notification shade or display settings. It may have different names: "Cast," "Smart View," "Wireless Monitor," or "Project."
When your phone starts searching for available devices, your TV should appear in the list. LGSelect it, and a connection permission prompt may appear on the TV screen, which you'll need to confirm with the remote. After that, the phone's image will be fully mirrored to the big screen. This method is ideal for sharing games, photo albums, or app interfaces in real time.
- 📱 Open Settings on your phone and find the "Connections" or "Display" section.
- 📺 Launch the app Screen Share on LG TV.
- 🔗 Tap "Cast" on your phone and select your TV from the list.
- ✅ Confirm the connection on the remote control.
It's worth noting that when using Miracast, your phone's battery may drain faster due to the active video stream and Wi-Fi connection. The phone may also be less responsive in this mode due to the high processor load.
☑️ Check before connection
Stream from iPhone via AirPlay 2
For equipment owners Apple I was luckier because modern TVs LG (2019 models and newer) officially support the technology AirPlay 2This means no third-party apps are required to broadcast videos, photos, or the entire screen. The process is fully integrated into the iOS system and works natively, ensuring high-quality video and audio with minimal latency.
To get started, make sure AirPlay is enabled in your TV settings. It's usually enabled by default, but it's worth checking. Go to Settings → Connection → AirPlayHere you can also configure security requirements: you can allow connections from any device on the network or require a code on the first connection, which increases the security of your home network.
To start casting, open Control Center on your iPhone (swipe down from the upper-right corner on newer models or swipe up on older models). Tap the Mirroring icon (two rectangles). Select your TV from the list that appears. LGIf everything is set up correctly, your phone screen will instantly appear on your TV. To stop the broadcast, simply tap the icon again and select "Stop Repeat."
⚠️ Attention: If you're using older LG TV models (pre-2018), AirPlay support may not be built in. In this case, you'll need to use third-party apps or connect your Apple TV via HDMI.
The advantage of AirPlay 2 is the ability to stream audio separately from video. You can play music on your TV while using your phone for other tasks without interrupting playback. Furthermore, the protocol supports playback control directly from the iPhone lock screen.
LG TV Plus app for advanced control
Official app LG TV Plus (formerly known as LG Remote) is a powerful tool not only for controlling your TV from your phone but also for streaming media files. It's available for free in stores. Google Play And App StoreOnce installed and launched, the app will automatically scan the network and prompt you to connect to the detected TV. A confirmation code will appear on the TV screen, which you'll need to enter on your smartphone.
The app's main feature for our purposes is the "Media" or "Gallery" tab. It lets you select photos or videos saved on your phone and send them to your TV. Unlike full screen mirroring, only the file itself is transmitted, reducing the load on your smartphone and allowing you to use it simultaneously. Playback quality is often higher, as the TV decodes the file automatically.
The app's interface is intuitive: a large touchpad for cursor control, a keyboard for text entry (which is much more convenient than typing search queries with the remote), and quick access to image and sound settings. This makes LG TV Plus A must-install tool for smartphone owners.

What should I do if the app doesn't detect the TV?
If LG TV Plus doesn't detect your TV, check to see if your phone's antivirus software is blocking your local network. Also, try rebooting your router. In rare cases, manually entering the TV's IP address in the app settings may help, if this option is available in the advanced menu.
Streaming content from browsers and YouTube
Video streaming from a browser deserves special attention. Google Chrome or applications YouTubeThis is perhaps the most popular scenario for using a phone-TV connection. Unlike mirroring the entire screen, it uses technology Cast, which only sends a link to the video stream to the TV. The TV downloads the video itself via its Wi-Fi channel, freeing up your phone and allowing you to watch high-quality videos (up to 4K) without choppy playback.
For YouTube, everything is as simple as possible: open the video on your phone, click on the broadcast icon (rectangle with waves) in the corner of the player and select your LG TVThe video will start playing on your TV, and your phone will become a remote control. You can pause, adjust the volume, or even close the YouTube app—playback won't be interrupted.
In the browser Chrome On Android or iOS, the process is similar. Open the desired page with the video, tap the menu (three dots), and select "Cast." The system will prompt you to select a device. This method is convenient for watching videos from websites that don't have a dedicated app but support web players.
- 🎬 Open the video in the YouTube app or browser.
- 📡 Click on the "Cast" icon.
- 📺 Select your LG TV from the list of available devices.
- ▶️ Enjoy watching using your phone as a remote control.
The unique feature of the Cast method is that it requires internet access on the TV itself, as it will download the content automatically. If the TV's internet connection is disconnected, this method won't work, unlike Miracast, which transmits images directly from the phone.
Troubleshooting and Frequently Asked Questions
Despite the simplicity of setup, users may encounter difficulties. The most common issue is that the TV doesn't appear in the list of available devices. In 90% of cases, this can be resolved by checking the network: make sure the phone isn't stuck on a 4G/5G mobile network and is connected to Wi-Fi. Restarting the router can also help, as it may have frozen and stopped distributing IP addresses to new devices.
Another common complaint is audio and video desynchronization or poor picture quality. This is a direct result of a weak Wi-Fi signal. Try moving closer to the router or disabling downloads on other devices on the network. If the problem persists, your router may be unable to handle streaming video, and you should consider upgrading to a more powerful model that supports the standard. Wi-Fi 5 (ac) or Wi-Fi 6 (ax).
⚠️ Attention: Operating system interfaces (Android, iOS) and webOS versions on LG TVs are regularly updated. Button layouts and menu item names may differ from those described in the instructions. Always follow the interface logic, not just the names.
If nothing helps, try resetting the network settings on your TV (Settings → Network → Wi-Fi → Remove) and reconnect it. This will clear the network settings cache and often resolve device visibility issues.
Why doesn't my LG TV detect my phone?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest network and the other to the main network) or that access point isolation is enabled on the router. Also, check if your phone is in "Data Saver" mode, which can block the search for local devices.
Is it possible to connect a phone to a TV without Wi-Fi?
Yes, but only with wires. USB-C to HDMI adapters are suitable for Android, and Lightning to HDMI (Digital AV Adapter) for iPhone. Wireless connection without a router is only possible via Wi-Fi Direct, if supported by specific models, but this is a less stable option.
The video is lagging when streaming from my phone. What should I do?
Reduce the video quality in your player settings, close unnecessary apps on your phone to free up RAM, and make sure there are no thick concrete walls or microwave ovens between your router and TV that could cause interference.
Is it safe to connect a personal phone to a public Smart TV?
Be careful. When connecting to other people's networks or unknown devices, do not transmit confidential data. After use, always disconnect from the device and remove the device from the trusted list in your router settings (if you are using guest access).
