Modern technology allows you to turn your smartphone into a powerful multimedia center, but the small screen of a mobile device isn't always convenient for viewing videos or photo albums. Owners of these devices LG People often ask how to display an image from Android on a big screen without using extra wires. Wireless connection via Wi-Fi — this is the most convenient and aesthetically pleasing way to free yourself from the clutter of cables and control content directly from your phone.
The device synchronization process relies on media streaming protocols such as Miracast or DLNA, which are built into the TV's operating system. To get started successfully both devices must be on the same local Wi-Fi network, meaning they must be connected to the same router. If you use mobile internet on your phone and a cable connection on your TV, a direct connection will not work without creating a bridge.
In this article, we'll cover all the setup details, potential issues, and solutions to help ensure stable signal transmission. We'll examine both the standard features LG WebOS, as well as the capabilities of third-party applications for specific tasks.
Preparing equipment and checking the network
Before you begin configuring software settings, you need to make sure your hardware is physically ready. Make sure your LG TV Connected to a Wi-Fi network and have an active internet connection. You can check this by launching any built-in service, for example, YouTube or NetflixIf the video doesn't load, the problem lies in your router settings or signal.
On the smartphone side, a number of conditions must also be met. Operating system Android must be updated to a current version that supports screen sharing functionality. In most modern models, this feature is called Smart View, Broadcast or Screen Mirroring and is located in the quick settings curtain.
Pay attention to the Wi-Fi network frequency. For high-resolution video transmission (4K or Full HD), it is preferable to use the band 5 GHz, as it provides higher throughput and lower latency.
⚠️ Important: If your router supports "Guest Network" mode, do not connect devices to it for streaming. This mode often blocks local communication between devices for security reasons.
Using LG's built-in Screen Share feature
Televisions LG with the operating system WebOS They are equipped with a native signal reception function. You don't need to search for and install additional apps on your TV if you use the standard Miracast protocol. To activate the reception mode, press the button on the remote control. Input or My Apps and find the application Screen Share.
After launching the app, the TV will enter connection standby mode. The device name and "Ready to connect" status will appear on the screen. At this point, the smartphone already sees the TV as an available device for projection.
Some TV models require connection confirmation on the TV screen. If you see a pop-up window requesting a connection from an unknown device, select "Accept" or "Always Allow" to avoid having to confirm the connection each time in the future.
☑️ Checking connection readiness
Setting up broadcasting from an Android smartphone
The Android interface may differ depending on the shell manufacturer (Samsung One UI, Xiaomi MIUI, Stock Android), but the logic remains the same. Pull down the top notification shade and find the broadcast icon. On devices Samsung it's called Smart View, on Xiaomi — Broadcast, but on a clean one Android — Screencasting.
Once the feature is activated, the phone will begin searching for available displays on the network. Your display should appear in the list. LG Smart TVTap it to begin pairing. The process takes 5 to 15 seconds, after which the image from your smartphone's screen will be completely copied to the TV.
It's important to understand the difference between the modes. You can mirror your entire screen or just specific content from apps. With full mirroring, notifications, calls, and other actions will be visible to all viewers on the big screen.
Using the LG TV Plus app to control
Official app LG TV Plus (formerly known as LG ThinQ) offers a deeper level of integration than simple screen mirroring. It allows you to not only display photos and videos from your gallery, but also use your smartphone as a remote control and transfer files without loss of compression quality.
To get started, download the app from Google Play and launch it. The program will automatically scan the network and offer to add your TV. A confirmation code may appear on the TV screen, which you'll need to enter on your smartphone to complete pairing.
The application has a "Media" section where you can select video files, music or photos stored in your phone's memory and send them for playback via DLNAUnlike Miracast, the phone acts as a remote control, and the TV decodes the file itself, reducing the strain on the smartphone's battery.
| Function | Screen Share (Miracast) | LG TV Plus (DLNA) | Google Home (Cast) |
|---|---|---|---|
| Transmission type | Screen mirroring | Streaming media files | Broadcasting application content |
| Phone addiction | High (screen on) | Low (can be folded) | Average |
| Picture quality | Depends on Wi-Fi signal | Original (uncompressed) | Adaptive |
| Control | From your phone (like a mouse) | Via the remote control app | Through the application interface |
Streaming via Google Home and Chromecast
Many modern televisions LG have built-in support for the technology Chromecast built-inThis allows you to stream content directly from compatible apps such as YouTube, Netflix, Instagram or browser Chrome, bypassing system mirroring limitations.
To use this method, make sure you have the service installed and updated on your TV. Google CastIn the app you want to stream the video from (e.g., YouTube), tap the rectangle icon with Wi-Fi waves in the corner. Select your TV from the list, and the video will start playing on the TV while you can use your phone for other tasks.
If there's no built-in support, you can use a physical Chromecast or similar device connected to the HDMI port. In this case, the steps are identical: search for the device in the app and start the stream.
What should I do if my TV is not visible in the list?
Make sure the "AP Isolation" feature is disabled on your router. Also, try rebooting your router, as multicast packets needed to find devices are sometimes blocked during extended network operation.
Resolving and eliminating delays
One of the main problems with wireless streaming is audio and video desynchronization or artifacts. This is often caused by a congested Wi-Fi channel or a weak signal. If the picture is lagging, try moving closer to the router or switching the TV to a wired (LAN) connection while leaving the phone on Wi-Fi.
It's also worth checking the output resolution. Some apps try to stream in 4K by default, which can be network intensive. You can manually lower the quality in the streaming app settings on your phone. 1080p or 720p to increase stability.
If the connection keeps dropping, try "forgetting" the Wi-Fi network on both devices and reconnecting. Sometimes resetting the TV's network settings via the menu helps. Settings → General → Network → Reset Wi-Fi.
⚠️ Please note: The menu interface on LG TVs may vary depending on the webOS version (3.0, 4.0, 5.0, 6.0, and higher). The layout of items may change, so please refer to the icons for their meaning, not just the text.
Alternative apps for advanced users
If the standard methods do not suit you in terms of functionality, the store Google Play offers a variety of third-party solutions. Apps like Cast to TV or AllCast Allows you to stream formats that are not supported by the TV's native player, thanks to built-in codecs.
There are also solutions for gamers that allow for low-latency streaming, which is critical for fast-paced games. However, keep in mind that even minimal Wi-Fi latency can reach 100ms, making shooters unsuitable for wireless play.
When using third-party software, carefully monitor permissions. The app needs access to the local network and media files, but don't grant access to contacts or the microphone unless absolutely necessary.
Why doesn't my LG TV detect my phone via Wi-Fi?
Most often, the problem stems from devices connected to different frequency bands (2.4 GHz and 5 GHz), which the router isolates from each other. Another possible cause could be an antivirus program on the phone or a router firewall blocking device discovery protocols (SSDP).
Is it possible to display the game screen on a TV without lag?
Wireless Miracast technology rarely delivers latency below 50-100 ms, which is noticeable in fast-paced games. For a smooth gaming experience, it's best to use an HDMI cable with a USB-C to HDMI adapter or game consoles connected directly to the TV.
Does broadcasting use up mobile data?
If you're streaming photos or videos already saved on your phone, your internet connection won't be used. However, if you're watching online videos (YouTube, online movie theaters), your data usage will be the same as if you were watching on your phone, since your phone acts as the controller, and your TV loads the stream itself (using Cast) or through your phone (mirroring).
