Modern Smart TV While smartphones have become full-fledged multimedia centers, smartphone screens often remain the primary source of content. A small display isn't always convenient for viewing family photos, vacation videos, or online lectures. Fortunately, technology makes it easy to stream content from a mobile device to a larger screen without the hassle of wires.
Equipment owners LG are in an advantageous position because the company has implemented several convenient data transfer protocols. You can use built-in operating system functions, special applications, or standards Miracast And AirPlay 2The setup process takes just a few minutes and doesn't require any advanced technical knowledge.
The main advantage of a wireless connection is freedom of movement. You don't need to search for HDMI cables or adapters; a stable home network is sufficient. In this article, we'll take a detailed look at all available display methods so you can choose the one that best suits your phone and TV model.
Preparing the equipment and WiFi network
Before you start the setup, you need to make sure that both devices are in the same connection conditions. Wireless network The connection must be stable, otherwise the stream will be intermittent or of poor quality. Check that your router is working properly and transmitting a signal at 2.4 GHz or 5 GHz.
TV LG must be connected to the same WiFi network as your smartphone. This is critical for devices to discover each other. If you're using a guest network or client isolation on your router, the connection may fail.
It's also worth updating your TV's software to the latest version. New firmware often contains fixes for video transmission protocols. Go to Settings → All settings → Support → Software update and check for updates.
⚠️ Note: If your router supports dual-band mode, make sure both devices are connected to the same frequency (for example, both to 5 GHz), although modern routers usually combine them into a single network.
For the best picture quality, we recommend using a 5 GHz network, as it offers higher throughput. However, it has a shorter range, so don't move too far from the router while watching.
Using Screen Share (Miracast)
The most universal way for Android smartphones is to use technology MiracastOn TV LG This function is often called Screen Share or ScreencastingIt allows you to duplicate the image 1:1, which is ideal for presentations or watching videos from apps that don't support Cast.

Once connected, the image from your phone will appear on the TV screen. Please note that in this mode, your smartphone's battery may drain quickly, as the WiFi module is constantly transmitting data. Your phone's screen will also remain lit at all times.
Streaming via Google Home and Chromecast

Make sure the Google Home app is installed and configured on your smartphone. Open the app and find your TV in the list of devices. Tap the device icon to open the control panel.
At the bottom of the screen, select the button Broadcast your screen or Cast my screenThe system will warn you about a possible audio or video delay, which is normal for wireless technologies. Confirm the action, and your smartphone screen will be displayed on the TV.
| Method | Quality | Delay | Battery consumption |
|---|---|---|---|
| Screen Share (Miracast) | High | Average | High |
| Google Cast | Adaptive | Low | Average |
| Apple AirPlay 2 | High | Low | Average |
| LG ThinQ app | Average | High | Short |
This method is convenient because it allows you to control playback directly from your phone without interrupting the stream. You can reply to messages or switch between apps, and the image on your TV will remain unchanged if the app supports split streaming.
What to do if the TV is not found?
If the search yields no results, try rebooting your router. Sometimes, temporarily disabling mobile internet (4G/5G) on your smartphone can help, forcing the system to search for devices only on the local WiFi network. Also, check whether your antivirus or firewall is blocking local device communication.
Connecting an iPhone via AirPlay 2
Equipment owners Apple can use the native function AirPlay 2, which is built into many models LG starting in 2019. This ensures the best picture quality and minimal latency for devices based on iOS.
Open Control center On iPhone (swipe down from the upper right corner or from the bottom up, depending on the model). Tap the icon Screen mirroring (two rectangles).

LG ThinQ Dedicated App
Company LG developed my own application LG ThinQ, which turns your smartphone into a universal remote control and media center. This solution is ideal for transferring photos and videos from your phone's gallery to a larger screen without duplicating the entire interface.
Download the app LG ThinQ from Google Play or the App Store. Register or sign in to your account. LGThe app will automatically find your TV on the network if you're logged in with the same account on both devices.
Select your TV from the list of devices. In the app interface, find the section Photos and videos or button BroadcastSelect the files from your phone's gallery that you want to display on the screen.
The main difference between this method and Screen Share is that it doesn't lock your phone. You can continue messaging or browsing the internet while a video is playing or photos are being shown on the TV. This is especially convenient for sharing content with friends.
Solving connection and quality issues
Despite the simplicity of setup, users sometimes encounter difficulties. Most often, the problem lies in the router's security settings or outdated software. If the TV stops detecting the phone, try restarting both devices.
Another common cause is using a VPN on your smartphone. A virtual private network changes your IP address and can isolate your device from the local network. Disable the VPN before attempting to connect.
If the image is choppy or has low resolution, check your network load. Downloading large files on other devices can clog your bandwidth. Also, try moving closer to your router.
⚠️ Note: Menu interfaces and feature names may vary depending on the version of webOS installed on your LG TV. On newer models (webOS 6.0 and above), some settings have been moved to the user profile.
Frequently Asked Questions

Yes, but only with wires. You can use a USB-C to HDMI adapter or a Lightning to HDMI adapter (for iPhone). This will allow the TV to function as a regular monitor and eliminate the need for a WiFi network. However, wireless streaming is not possible.
Why is there no sound when broadcasting video?
Check the audio settings in the app you're streaming from. Sometimes the audio remains on your phone, but the video goes to your TV. Also, make sure the TV isn't in low volume or headphone mode. Reconnecting often resolves audio stream sync issues.
Do older LG TVs support Screen Share?
Most LG Smart TVs released after 2013-2014 support Miracast technology. However, on very old models with the NetCast operating system, the feature may have a different name or require a special app to be installed on the PC for broadcasting.
Does broadcasting affect internet speed?
Yes, when mirroring your screen (Miracast/AirPlay), the traffic flows within the local network and doesn't consume internet bandwidth. However, when using Chromecast or YouTube, the TV automatically downloads content from the internet, which may reduce speeds on other devices.
