The main advantage of a wireless connection is freedom. You don't need to search for HDMI cables or adapters if you have a stable network. The synchronization process takes only a few minutes, and the transmitted image quality often surpasses standard over-the-air broadcasts.
In this article, we'll cover all current connection methods, from built-in system functions to specialized apps. We'll explore the nuances of different operating systems and help solve common issues users encounter during initial setup.
Basic requirements and equipment preparation
Before you begin setup, you need to make sure your hardware meets the minimum technical requirements. The first and most important requirement is the module. Wi-Fi Both devices support wireless. Most modern smartphones and all LG Smart TVs have a built-in wireless adapter.
It's crucial that both devices are on the same local network. This means both the phone and TV must be connected to the same router. If you have a dual-band router, it's best to use a network. 5 GHz for transmitting high-definition video, as it provides greater bandwidth.
⚠️ Important: If your router divides the network into guest and main, make sure that traffic is not isolated between them (AP Isolation), otherwise the devices will not "see" each other in the list of available devices.
It is also worth checking the TV software version. Function Screen Share or Miracast May not work correctly on older firmware versions. System updates often fix connection issues and add support for new codecs.
Using the built-in Screen Share (Miracast) feature
The most universal method that does not require the installation of additional software is technology MiracastIn LG TVs this function is often called Screen ShareIt allows you to stream images from your smartphone to your TV in real time, creating a direct wireless connection.
To start working, press the button on the remote control. Input or go to the signal source selection menu. In the list of available applications, find and launch Screen ShareA message about waiting for connection will appear on the screen, along with the name of the device.
- 📱 Open Settings on your Android smartphone.
- 📡 Find the "Connections" or "Broadcast" section (the name depends on the model).
- 🔍 Click "Search for devices" and select your LG TV from the list.
- ✅ Confirm the connection request that appears on the TV screen.
Once paired successfully, your phone's screen will be mirrored to your TV. You can switch between apps, and the image will change accordingly. However, remember that when using this method, your smartphone must be close to the router to ensure a stable signal.
Connecting via the LG ThinQ app
Owners of modern LG Smart TV models (especially those based on webOS 4.0 and newer) can use the official application LG ThinQThis software turns your smartphone into an advanced remote control, allowing you to not only stream content but also control your TV settings.
Download the app from Google Play or App Store and install it. When you first launch the program, you'll be asked to create an account or sign in to an existing one. Next, click the "Add Device" button and select your TV from the list found on your local network.
A confirmation code will appear on the TV screen, which you'll need to enter in the app. Once paired, you'll gain access to the "Screen Casting" feature. Unlike Miracast, this feature offers more flexible controls: you can select specific photos or videos from your gallery without displaying phone notifications on the big screen.
⚠️ Note: The LG ThinQ app interface may differ depending on your phone's operating system version and TV model. Some older TV models may not be supported by the new version of the app.
☑️ Pre-connection check for ThinQ
Stream from iPhone and iPad (AirPlay 2)
Apple users will appreciate the technology support AirPlay 2 on LG TVs. This feature is built directly into the webOS system, starting with certain 2019 models, allowing you to stream content without installing third-party apps.
Make sure AirPlay support is enabled on your TV. To do this, go to Settings → Support → AirPlay Settings and activate the feature. Now on your iPhone, just open Control Center and tap the "Screen Mirroring" button.
Select your LG TV from the list of devices. If this is your first time using the TV, you may see a prompt on the TV screen asking for permission to connect. Once confirmed, the image from your iPhone or iPad will appear on the TV with minimal delay.
A unique feature of AirPlay is the ability to use your phone while watching. You can reply to messages or play games, and the image on your TV won't change until you launch the video in a compatible app. This makes the technology ideal for displaying photo albums in the background.
What to do if AirPlay is not found?
If your TV doesn't appear in the AirPlay list, try restarting your router. Also, make sure Client Isolation isn't enabled on your router, which prevents devices on the same network from communicating with each other.
Comparison of connection methods and their features
The connection method you choose depends on your goals and the device model. Each method has its own advantages and limitations, which should be considered before use.
| Method | Image quality | Delay | Battery consumption |
|---|---|---|---|
| Screen Share (Miracast) | High (up to 1080p) | Average | High |
| LG ThinQ App | Depends on the file | Low | Average |
| AirPlay 2 | Maximum (4K HDR) | Minimum | Optimal |
| DLNA (Media) | Original file | No (locally) | Short |
Technology Miracast It's good for sharing the entire screen, but it puts a lot of strain on the phone's processor because it encodes the video stream in real time. AirPlay and application ThinQ work more efficiently by transmitting a ready-made stream or playback command.
If you simply want to show a photo or play a movie from your phone's memory, it's better to use built-in media players with DLNA support or the "Cast" function within the app itself (for example, the Cast button in YouTube). This will reduce the load on your smartphone's battery.
Solving common connection problems
Despite the simplicity of setup, users may encounter difficulties. Often, the problem lies in the devices simply not seeing each other. First, check if Wi-Fi on both devices and whether the "Airplane" mode is activated.
Another common cause is using different Wi-Fi frequencies. If your router broadcasts a 2.4 GHz and 5 GHz network with different names (SSIDs), make sure your phone and TV are connected to the same network, even if they're in the same band.
- 🔄 Restart your router and TV - this solves 80% of network discovery problems.
- 📶 Move closer to the router if your phone's Wi-Fi signal is weak.
- 🛡️ Check your antivirus or firewall settings on your router, as they may be blocking local traffic.
If the image is streaming but is choppy or choppy, try lowering the video quality or closing background apps on your smartphone. Switching the Wi-Fi channel in your router settings to a less congested one may also help.
⚠️ Please note: Some corporate or public Wi-Fi networks may prohibit traffic transfer between devices (Client Isolation). In these conditions, connecting your phone to your TV will not work without access to the router settings.
