Connecting your smartphone to an LG Smart TV via Wi-Fi Direct

Modern televisions LG Smart TV are powerful multimedia centers, but their functionality is fully revealed only when synchronized with mobile devices. Technology Wi-Fi Direct Allows you to stream content directly, bypassing the router, ensuring high speed and a stable connection. This is especially useful when you need to show photos to guests or play videos from your phone on a big screen without lag.

The setup process may seem complicated due to the variety of operating systems and versions. WebOSHowever, once you understand the protocol's basic principles, you can easily control your smartphone's screen on your TV. In this article, we'll cover all the connection details, including how to work with Android and iOS, as well as troubleshooting common errors.

Using a direct wireless connection relieves the local network of unnecessary load. This means that even if other devices in the house are actively downloading files, video streaming to LG TV will remain smooth and without buffering.

How Wi-Fi Direct works on LG TVs

Technology Wi-Fi Direct Creates a direct peer-to-peer connection between two devices. Unlike a traditional router connection, the TV itself acts as an access point or peer node. The protocol supports data transfer at speeds comparable to standard Wi-Fi, which is critical for high-definition video streaming. 4K UHD.

System LG WebOS uses standardized protocols to implement this feature. For Android devices, this is most often Miracast, which is built into the system at the kernel level. For Apple devices, the protocol used is AirPlay 2, which also works over direct wireless connections, providing encryption and low latency.

⚠️ Attention: When connected to Wi-Fi Direct, a mobile device may not be able to access the Internet if it does not support the simultaneous operation of two Wi-Fi modules or specific channel sharing modes.

It is important to understand that Screen Share On LG TVs, Wi-Fi Direct is a software implementation of the Wi-Fi Direct standard. It allows not only screen mirroring but also the use of a phone as a remote control or keyboard. This is achieved by exchanging service data packets immediately after a handshake is established between the devices.

Equipment preparation and compatibility testing

Before you begin setup, you need to make sure your hardware supports the required features. Most models LG Smart TV, released after 2015, have a built-in Wi-Fi Direct module. However, older devices may require an external adapter, although this is extremely rare these days.

There are also requirements on the smartphone side. For Android, this means the presence of the "Wireless Display" or "Cast" function. Devices based on iOS must support AirPlay. Checking compatibility takes a couple of minutes but eliminates future connection issues.

Make sure the wireless modules are enabled on both devices. Even if the connection is direct, the radio must be active to scan for neighbors. It's also worth checking if your phone's power-saving mode is enabled, which could block background network scanning.

The table below lists the basic software requirements for successful synchronization:

Android Tutorial: Using Screen Share

Owners of smartphones based on Android There are several ways to activate the connection. The most reliable method is to use the system's built-in function. The menu may have different names depending on the manufacturer: "Cast," "Smart View," "Wireless Monitor," or "Project."

First, take the remote control. LG TV and press the button Input or go to the launcher. Find the app Screen ShareIn new versions WebOS It may be called "Device Connector" or be built into the external device connection menu. Select "Receiver" or "TV Ready" mode to put the TV into standby mode.

If the image doesn't stretch to fill the entire screen, check the aspect ratio settings in the TV menu, usually by clicking the button. P:Ratio or Aspect Ratio.

⚠️ Attention: The Android menu interface may differ depending on the operating system (MIUI, OneUI, ColorOS). If the standard search doesn't work, try downloading the official app. LG TV Plus from Google Play.

Setting up AirPlay for iPhone and iPad owners

Apple's ecosystem uses the protocol AirPlay 2, which is integrated directly into the system. To connect to LG Smart TV No need to install additional apps if your TV supports this feature (2019 and newer models, or TVs with updated firmware).

Make sure AirPlay is enabled on your TV. To do this, go to Settings → Connection → AirPlayHere you can set the device name that your phone will see and set a passcode. We recommend setting the passcode to "First Time Only" or "Manual" to prevent others from accessing your screen.

On your iPhone, open Control Center. On models with Face ID, swipe down from the top-right corner; on models with a Home button, swipe up from the bottom. Tap the Home button. Screen mirroring (two rectangles). Select yours from the list. LG TV.

If the connection is successful, a four-digit code will appear on the TV screen. Enter it on your smartphone. Your phone's screen will now be mirrored on the TV. To stop the broadcast, tap the icon in Control Center again and select "Stop Repeat."

Using the LG TV Plus app for advanced control

Official app LG TV Plus (formerly LG Remote) offers a deeper level of integration than standard Miracast. It allows you to not only cast photos and videos from your gallery, but also control your TV and transfer files. The app is available in App Store, and in Google Play.

For the app to work, the devices must be on the same Wi-Fi network (connected to the same router), although some features can be enabled via Direct. After installation, launch the app and click "Connect to TV." Select your TV from the list. A pairing request will appear on the TV screen; confirm it with the remote.

In the "Gallery" or "Media" sections of the app, you can select any files on your smartphone to display on the screen. This is convenient for browsing personal archives, as the app supports more formats than the built-in player. A "Mircaste" feature is also available, which mirrors the screen similar to a system broadcast.

A unique feature of the app is its file transfer capabilities. You can transfer a document or photo from your phone to the TV and save it to the TV's internal memory or a connected USB drive. This is a unique feature that isn't available with standard screen mirroring.

What should I do if the app doesn't detect the TV?

Make sure both devices are connected to the same network (2.4 GHz or 5 GHz). Check if your phone's antivirus software is blocking the local connection. Try rebooting your router.

Streaming content from browsers and YouTube

Often users don't need to duplicate the entire screen, but only want to show a specific video. Protocol DLNA and function Cast allow you to do this effectively. In the browser Google Chrome On Android or iOS, tap the menu (three dots) and select "Broadcast."

There is a similar function in the application YouTubeClick on the broadcast icon (rectangle with waves) in the corner of the video. Select your LG TVThe video will start playing on your TV using its internet connection, saving your phone's battery. In this case, your phone only acts as a remote control.

The advantage of the Cast method is that video quality depends on the internet speed of the TV, not the phone. You can minimize the YouTube app or even turn off your phone's screen—video playback on the TV will not be interrupted. This is ideal for watching movies.

However, if the video isn't loading or is buffering, check your DNS settings. Sometimes ISPs block streaming. You can configure your TV's network settings to use a public DNS, such as Google's (8.8.8.8), which often solves the problem of access to content.

⚠️ Attention: The Cast feature only works if the content is copyright-protected (DRM) or the app supports external streaming. Some websites may block the display of protected video on external screens.

Troubleshooting: TV doesn't detect phone or connection is lost

The most common issue is that devices can't find each other. Make sure "SIMPLE LINK" or "LG Connect Apps" is enabled in your TV's network settings. Without this permission, the TV won't respond to requests from external devices, even if Wi-Fi Direct is enabled.

If you have a connection but the picture is choppy or intermittent, interference may be the issue. Wi-Fi Direct operates on the 2.4 GHz frequency, which is very noisy in apartment buildings. If possible, switch both devices to the network. 5 GHz, if your router and TV support this range.

It's also worth checking the date and time on both devices. Clock desynchronization can lead to security certificate errors, which can prevent the handshake between devices. Set automatic time synchronization via the network.

Why does the sound disappear when screen sharing?

This is a limitation of the Miracast protocol on some Android models. Try using the LG TV Plus app or connecting external speakers to your phone.

In extreme cases, resetting the network settings will help. On the TV, this is done through Settings → All settings → General → Factory reset (Be careful, this will erase all your settings.) On your phone, simply select "Forget network" for Wi-Fi Direct and try connecting again.

Please remember that the software is constantly being updated. If you encounter a bug, please check for updates. WebOS In the "Support" section. LG engineers regularly release patches that improve compatibility with new versions of Android and iOS.
