Modern multimedia capabilities make it possible to turn any smartphone into a powerful remote control and content source for the big screen. LG owners often wonder how to connect their Android device to their LG TV via Wi-Fi to stream photos, videos, or even mirror the image in real time. This is especially convenient when you need to share a presentation with colleagues or play a movie from an untrusted source directly on the 55-inch screen.
The setup process may vary depending on your operating system version. WebOS, installed on your TV, and your smartphone model. Some methods require installing additional software, while others work natively through the system menu. The key is to ensure a stable connection between the devices, as transmitting high-definition video requires ample bandwidth.
In this article, we'll cover all current synchronization methods, from built-in features to third-party utilities. You'll learn how to avoid image lag and audio desynchronization. We'll also cover common errors that occur when trying to establish a connection between devices from different manufacturers.
Preparatory stage: checking the network and settings
Before you start pairing devices, you need to make sure that both gadgets are in the same network conditions. Basic requirement For most wireless data transfer methods, the smartphone and TV must be on the same local network. This means they must be connected to the same router.
A common mistake users make is using a guest Wi-Fi network or different frequency bands without configuring their router accordingly. If your router broadcasts 2.4 GHz and 5 GHz signals as two different networks with different names (SSIDs), make sure both devices are connected to the same band. Ideally, it's better to use the same band for video transmission. 5 GHz, as it provides higher speed.
⚠️ Note: If the "AP Isolation" feature is enabled on your router, devices will not be able to see each other even when connected to the same network. This option must be disabled in your router settings.
It's also worth checking that the Wi-Fi module is enabled on the TV itself. On LG models, this can be done through the menu. Settings → All settings → Network → Connect to a Wi-Fi networkMake sure the connection status shows "Connected" and the signal is strong enough.
Using Screen Share (Miracast)
The fastest way to display an image from your phone screen on a TV is to use technology Miracast, which is often called Screen Share on LG TVs. This method allows you to mirror your smartphone's screen without having to install additional apps on your TV, as protocol support is built into the system. WebOS.
To start using the LG TV remote control, press the button with the image of a house or a separate key Screen Share (Depending on the remote model). A list of available devices or a connection standby mode will appear on the screen. Now let's move on to the smartphone settings.
On Android devices, the function path may have different names: "Cast," "Smart View," "Wireless Monitor," or "Projection." Typically, this option is hidden in the notification shade or in a menu. Settings → Connected devices → BroadcastOnce the search is activated, your phone will detect your LG TV.
☑️ Miracast connection algorithm
It's worth keeping in mind that using this method may cause the smartphone to heat up more and drain the battery faster, as the video stream is encoded and transmitted in real time. Furthermore, in landscape mode, some apps may scale incorrectly, leaving black bars around the edges.
The official LG TV Plus app
LG has developed its own app LG TV Plus, which turns your smartphone into an advanced remote control and allows you to stream media files. Unlike simple screen mirroring, you can select specific photos or videos from your gallery and send them to the big screen while continuing to use your phone for other tasks.
To get started, download the app from the Google Play Store. Once launched, the app will prompt you to find your TV on the network. Make sure the mobile app is allowed access in the "Connection Manager" menu or in the list of devices on your TV. When connecting for the first time, a confirmation code may appear on the TV screen, which you'll need to enter on your smartphone.
The app's functionality isn't limited to media. It allows you to:
- 📱 Control the mouse cursor on the TV screen using your smartphone's touchscreen.
- 🔊 Adjust the volume and change channels without searching for the remote.
- 📷 Upload photos from your phone gallery to your TV screen to view a slideshow.
- ⌨️ Enter text into the search bar of your browser or YouTube on your TV using your phone's keyboard.
⚠️ Please note: The LG TV Plus app interface may differ depending on the TV's year of manufacture. Newer models with webOS 6.0 and higher may have limited functionality compared to older versions.
The app's unique feature is that it uses the DLNA protocol for file transfer, rather than direct screencasting. This means you won't be able to launch a game on your phone and watch it on your TV, but it's ideal for viewing personal video archives.
Streaming via Google Home and Chromecast
Many modern LG TVs support built-in technology Chromecast built-inThis allows you to stream content directly from apps like YouTube, Netflix, or Google Photos without using your phone's system features. This process often requires an app. Google Home.
If your TV supports this feature, it will automatically appear in the list of devices in the Google Home app. Tapping the TV icon will reveal the "Cast Screen" button. This action completely mirrors the Android interface to your TV.
The advantage of this method is its high stability and optimization. When you launch a video in a supported app (such as YouTube), your phone acts only as a remote control, while the TV downloads the video stream directly from the internet. This saves battery life and ensures better picture quality.
| Parameter | Miracast (Screen Share) | Chromecast built-in | DLNA (LG TV Plus) |
|---|---|---|---|
| Transmission type | Screen mirroring | Streaming/Mirroring | File transfer |
| Phone addiction | High (screen should be lit) | Low (for streaming) | Average |
| Video quality | Depends on Wi-Fi signal | Maximum (up to 4K HDR) | Depends on the file format |
| Control | From the phone | From your phone or TV remote control | From the phone |
It's important to note that Chromecast requires a Google account and Google Play services on your TV. This feature may not be available in some regions or on older models, so you'll have to rely on Miracast.
Why does the video lag when broadcasting?
Lag is most often caused by Wi-Fi channel congestion. If a microwave is running nearby or a neighbor's router is using the same channel, data transfer speeds will drop. Try switching your router to a less congested channel or using the 5 GHz band.
Third-party streaming apps
If the standard tools are not satisfactory or do not work correctly, third-party solutions come to the rescue. Cast to TV - XCast or Web Video Caster are popular tools that can find DLNA and Chromecast devices where system functions fail.
They work simply: you open a video file or a link to a video stream within the caster app, select your LG TV from the list, and the program sends a playback command. Some of them even support video formats that the TV doesn't support out of the box, transcoding them on the fly.
When using such programs, it's important to pay attention to permissions. They may require access to the local network and media files to function properly. Without these permissions, the app simply won't be able to see the TV or open videos.
Some advanced users prefer to install universal players on LG TVs (if the WebOS version allows it and there is access to the app store), such as VLC or KodiWhen paired with the mobile version of these players, you can achieve excellent results in managing your media library.
⚠️ Please note: Third-party apps often contain ads or offer paid subscriptions to unlock features like 4K streaming. Be careful when choosing software.
Troubleshooting connection and visibility issues
Users often encounter a situation where the TV simply doesn't detect the phone, or the connection constantly drops. The first step is to reboot both devices. Simply turning the router, TV, and smartphone off and on solves up to 80% of network service cache issues.
If the problem persists, check your router's firewall or antivirus settings. Sometimes security mechanisms block ports required for protocols. DLNA or MiracastIt's also worth making sure your phone isn't in "Data Saver" or "Power Saver" mode, which can limit background network activity.
If you see an image but no sound, check the audio output settings in the app you're streaming from. Often, the audio defaults to your phone and needs to be manually switched to the output device (TV).
Another cause of problems could be outdated software. Check for firmware updates for your TV in the menu. Settings → Support → Software UpdateNew versions often contain compatibility fixes with new versions of Android.
Comparison of methods and selection of the optimal one
The choice of connection method depends on your specific needs. If you simply need to share photos with friends or play a movie from your phone's memory, built-in LG TV Plus or DLNA tools are the most convenient. They don't require constant attention to the smartphone screen.
Miracast (Screen Share) is indispensable for sharing your desktop, games, or apps that don't support Cast. However, be aware of potential control lag, making this method less suitable for fast-paced games.
If you're looking for a comfortable way to watch streaming services, it's best to use the built-in Chromecast or native apps on your TV. This will ensure the best picture quality and minimize the load on your smartphone.
Why can't my LG TV detect my Android phone?
Most often, the problem lies in the devices being connected to different networks (for example, one to a guest network, the other to the main network) or to different router frequencies, which are isolated from each other. It's also worth checking whether your phone's antivirus software is blocking local connections.
Is it possible to connect a phone to a TV without a Wi-Fi router?
Yes, if your TV and phone support Wi-Fi Direct technology. In this case, they connect directly, creating their own mini-network. However, the speed and stability of this connection may be lower than with a full-fledged router.
Does connecting a phone affect the picture quality on TV?
When using streaming methods (Cast/Chromecast), where the TV downloads the content itself, quality is not affected. When using screen mirroring (Miracast), quality may be reduced due to video stream compression and interference in the Wi-Fi channel.
How to improve video transfer speed over Wi-Fi?
Use the 5 GHz band and ensure there are no thick walls or metal barriers between the router and your devices. Also, close any unnecessary apps on your phone that are consuming data.
