Modern smartphones have high-resolution screens, but for comfortable movie watching in company or just to relax, you often want to display the image on a larger screen. Televisions LG Smart TV provide extensive capabilities for wireless transmission of multimedia content using standard Wi-Fi routerThis eliminates the need to purchase additional cables or complex adapters.
The process of synchronizing your gadget and TV depends on your mobile device's operating system and TV model. In most cases, both devices need to be on the same local network. It is critical that the devices are connected to the same Wi-Fi network, and not to a guest network or via mobile 3G/4G. In this article, we'll cover all current connection methods, including built-in features and third-party apps.
Before you begin setting up, make sure your TV is LG supports the function Smart Share or has built-in protocol support AirPlay 2 And MiracastAlmost all models released after 2015 are equipped with the required wireless module. If you have an older model but with an HDMI port, there are alternative options, which we'll also mention.
Preparing equipment and network
The first step is to properly set up a wireless network. A stable signal is required for stable transmission of high-resolution video streams (Full HD or 4K). It is recommended to use a range 5 GHz, if your router and TV support this frequency. This will provide higher channel throughput.
Check what's on your TV LG The Wi-Fi function is enabled. To do this, press the settings button on the remote (usually a gear) and go to the section All Settings → Network → Connect to a Wi-Fi networkMake sure the connection status is active and the IP address is obtained automatically.
⚠️ Note: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, make sure that both your phone and TV are connected to the same frequency, preferably 5 GHz for high-quality video.
It's also worth updating your TV's software to the latest version. Manufacturers often release patches that improve the stability of data transfer protocols. Go to Settings → Support → Software Update and run the scan.
You should also check your mobile device settings. Make sure "Mobile Data" is temporarily disabled to avoid routing conflicts, although modern systems typically prioritize Wi-Fi connections for local data transfers.
Stream from iPhone and iPad (AirPlay 2)
For device owners Apple luckier than anyone else, since many modern televisions LG natively support the technology AirPlay 2This allows you to stream videos, photos, and even your smartphone screen without installing additional apps. This technology ensures minimal latency and high image quality.
To start casting, open Control Center on your iPhone or iPad. On models with Face ID, swipe down from the top right corner; on models with a Home button, swipe up from the bottom. Find the "Screen Mirroring" icon (two rectangles).
Select your TV from the list of available devices. LGIf this is your first time using the app, a confirmation code may appear on your TV screen. Enter it on your smartphone. Afterward, the phone's image will be fully mirrored on the big screen.
- 📺 To stream videos from apps (YouTube, Netflix, Kinopoisk), use the built-in "Stream" button (the rectangle icon with waves) rather than screen mirroring to maintain quality and control.
- 🔊 The audio will also be transmitted to the TV, but it can be redirected back to the phone via Control Center.
- 🔄 If your TV isn't visible, check if AirPlay is enabled in your LG settings:
Settings → Support → AirPlay.
It is important to note that when duplicating the screen (Screen Mirroring) The image's aspect ratio may not match the TV's screen format, and black bars will remain on the sides. This is normal for content not adapted to 16:9.
Using the LG ThinQ app for Android and iOS
Official app LG ThinQ is a universal smart home management tool from the South Korean giant. It allows you to not only control your TV settings but also stream media files stored on your smartphone. This is a great option if standard protocols are unstable.
Download the app LG ThinQ from Google Play or the App Store. After installation, launch it and sign in to your LG account (or create a new one). Click "+" to add a device and select your TV from the list found on the network.
Once paired, go to the TV control menu within the app. Find the "Cast" section or the media icon. Here you can select photos, videos, or music to play on the TV screen.
⚠️ Please note: The LG ThinQ app may not support streaming DRM-protected content from some streaming services. For Netflix or YouTube, it's best to use the built-in Cast features.
The advantage of this method is that your phone acts as a remote control. You can pause, rewind, and adjust the volume without leaving your couch. The app also lets you upload files directly from your phone, bypassing complex menus.
Miracast and Screen Share technology
Protocol Miracast (in LG TVs it is often called Screen Share) is designed for screen mirroring. It creates a direct Wi-Fi connection between devices, bypassing the router, or uses the local network to transmit the video stream. It is the de facto standard for devices based on Android.
On TV LG you need to run the application Screen Share (It's usually found in the app list or under "Connection Manager"). A "waiting for connection" message will appear on the screen.
On an Android smartphone, this feature may have different names depending on the manufacturer: "Cast," "Smart View" (Samsung), "Wireless Monitor" (Xiaomi), or "Projection." This option is typically found in the notification shade or in the display/connection settings.
Find your TV in the list and tap it. The image from your phone will appear on the TV. It's important to understand that in this mode, your phone completely mirrors your screen, so notifications and calls will also be visible to everyone present.
| Parameter | Miracast (Screen Share) | DLNA / Smart Share | AirPlay 2 |
|---|---|---|---|
| Transmission type | Screen mirroring | Transferring media files | Mirroring and media |
| Delay | Low (depending on signal) | Absent | Minimum |
| OS support | Android, Windows | All (via apps) | iOS, macOS |
| Quality | Compressed video | Original file | High |
☑️ Pre-broadcast check
Streaming via Google Home and Chromecast
If your TV LG works on the platform webOS version 4.0 and above, it often has built-in support Google Cast (Chromecast built-in). This allows you to stream content directly from apps that support this feature, such as YouTube, Google Photos, VLC, and many others.
For this method to work, you must have the app installed on your phone. Google HomeOpen it and find your TV in the list of devices. Make sure the status is "Ready to set up" or "Connected."
Open the video in an app (e.g., YouTube). Tap the cast icon (the rectangle with waves in the corner). Select your LG TV. The video will start playing on the TV, and you can use your phone for other tasks or turn off the screen.
This method is the most energy-efficient, since the phone does not encode the video stream in real time, but only acts as a remote control, telling the TV which file to download and play from the Internet.
⚠️ Please note: App and TV interfaces are subject to update. Button locations and menu item names may differ from those described in the instructions. Always refer to the latest user manual on the manufacturer's official website.
What should I do if my TV isn't found in Google Home?
Make sure Bluetooth is enabled on your phone and TV (for the initial search), and all location and local network permissions are granted to the Google Home app. Restarting the router can sometimes help.
Troubleshooting connection issues
Even with proper setup, glitches can still occur. A common issue is audio and video desynchronization or intermittent image freezing. This almost always indicates Wi-Fi bandwidth issues.
Try disabling other devices that are actively consuming bandwidth (game downloads, torrents). If the problem persists, reboot the router by unplugging it for 10-15 seconds. This will clear the buffer and select a less congested channel.
If your phone sees your TV but doesn't connect, try using the app on your TV. Screen Share Or disable and then re-enable the function for accepting external connections in the network settings. Also, check if your router is set to AP Isolation mode, which prevents devices within the network from seeing each other.
- 🔒 Check your antivirus or firewall on your phone; they may be blocking local connections.
- 📶 When using the 2.4 GHz band, make sure there are no strong sources of interference nearby (microwaves, baby monitors).
- 📱 On Android, you can try changing the video encoder in developer mode, but this is for advanced users.
If your wireless connection absolutely refuses to work reliably, you can always use an HDMI cable with the appropriate adapter for your smartphone (USB-C to HDMI or Lightning to HDMI).
Comparison of methods and final recommendations
The connection method you choose depends on your goals. For viewing party photos, DLNA or application LG ThinQFor displaying presentations or desktop - Miracast. And for watching movies from online cinemas, it is best to use the built-in Chromecast or AirPlay.
Keep in mind that streaming over Wi-Fi can drain your smartphone's battery faster than usual, especially when using screen mirroring protocols. It's recommended to keep your phone close to a charger or use a power bank.
Modern technologies make the process as simple as possible. The key is to keep your devices' software up to date and ensure proper operation of your home network.
Frequently Asked Questions (FAQ)
Is it possible to connect a phone to an LG TV without Wi-Fi?
Yes, this is possible with a cable. For Android, you'll need a USB-C to HDMI (MHL) adapter, and for iPhone, a Lightning to HDMI adapter. Some TV models also support USB connection, but only for playing files from a flash drive, not for live screen sharing.
Why does the video jerk or stutter when streaming?
Most likely, the Wi-Fi signal is too weak or the channel is congested. Try moving the router closer to the TV, switching to the 5 GHz frequency, or reducing the video quality in the source app. Also, make sure your phone isn't in power-saving mode.
Do older LG TVs support Smart View?
Older models (pre-2012-2013) may not have a built-in Wi-Fi module or support for modern protocols. In this case, you'll need to purchase an external set-top box (such as an Android Box or Apple TV) that connects via HDMI and provides Smart TV functionality.
How to stream audio only to the TV while turning off the phone screen?
This is only possible when using apps that support Chromecast or AirPlay (YouTube, Netflix, music services). When using full screen mirroring (Miracast), the phone usually needs to remain active, although some models allow you to turn off the screen while still transmitting audio.
