Modern smartphones have high-resolution screens, but to fully immerse yourself in a movie, you still want to see the image on a larger diagonal. LG device owners are in an advantageous position, as the platform webOS offers a variety of built-in tools for streaming content. You don't need to buy complex set-top boxes or run long HDMI cables if you have a local network set up in your home.
There are several proven ways to transmit images: from simple screen mirroring to streaming via DLNA servers. Connection stability Plays a key role here, so before you begin setting it up, make sure your router is working properly. In this article, we'll cover all the current methods that will let you start playing a movie in just a couple of minutes.
The setup process may vary slightly depending on your mobile device's operating system version and the year of your TV's release. However, the basic principles remain the same for all models in the series. LG Smart TVLet's look at how to turn your gadget into a home theater remote control.
⚠️ Please note: the quality of the streamed video directly depends on the Wi-Fi speed. If the router is located far from the TV, frame drops or audio desynchronization may occur.
Preparing equipment and a Wi-Fi network
The foundation of successful streaming is a properly organized local network. The most important rule: both devices—the smartphone and the TV—must be connected to the same Wi-Fi network. If you have a dual-band router, make sure the devices can see each other, even if they're on different frequencies (2.4 GHz and 5 GHz).
In some cases, routers with the function AP Isolation Client isolation (client isolation) can block direct connections between devices within the network. This is a standard security measure in public places, but at home it's just a nuisance. Check your router settings and, if necessary, disable this feature for your home network.
It's also worth updating your TV's software to the latest version. Manufacturers are constantly improving data transfer protocols and fixing compatibility issues. Go to the settings menu and select system update to ensure you have the latest firmware.
Screen Share (Miracast) method for screen mirroring
The fastest way to display an image is to use technology Miracast, which is often called Screen Share on LG TVs. This method allows you to completely clone the image from your phone to the big screen in real time. For Android devices, this is a built-in feature that doesn't require any additional software.
To start casting, look for the "Cast," "Smart View," or "Wireless Monitor" button in your smartphone's notification bar. After scanning the network, you'll see your TV's name. LG webOS TVClick on it, and a connection request will appear on the TV screen, which you will need to confirm with the remote.
Keep in mind that when mirroring your screen, your smartphone remains active. If you receive a message or minimize an app, it will appear on your TV. This method also consumes more battery power, as the phone's video processor is under increased strain.
☑️ Check before launching Screen Share
Using the LG TV Plus app
Official app LG TV Plus (or its newer version, LG ThinQ) offers advanced functionality compared to standard mirroring. It allows you to not only share photos and videos from your gallery but also use your phone as an advanced keyboard for typing in searches.
After installing the app and pairing it with your TV, go to the media section. Here, you can select a video file already downloaded to your phone's memory and play it. Unlike Miracast, the TV decodes the video file itself, offloading the smartphone's processor.
Pay special attention to file formats. The TV's built-in player may not support some rare codecs or containers that are easily read by a phone. In this case, it's better to use third-party players with DLNA support or mirror the entire screen.
⚠️ Please note: The LG TV Plus app interface may differ on different versions of Android and iOS. Functionality for iPhone (iOS) is often limited compared to the Android version due to Apple's policies.
Streaming via Google Home and Chromecast built-in
Many modern LG models are equipped with built-in support ChromecastThis allows you to stream content directly from source apps like YouTube, Netflix, or the Google Chrome browser. Picture quality is typically higher in this case, as the stream goes directly from the server to the TV, bypassing the phone.
To launch, find the rectangle icon with waves in the corner in the app (for example, YouTube). Select your TV from the list. Your phone acts as a remote control: you can skip videos, pause, adjust the volume, and even exit the app without interrupting your viewing.
If there's no built-in feature, you can use an external Chromecast box or Android TVs connected to the LG HDMI port. The operating principle remains the same: the devices must be on the same network and authenticated with their Google accounts.
What should I do if my TV isn't visible in the Chromecast list?
Make sure client isolation isn't enabled on your router. Also, check that your antivirus software on your phone or PC isn't blocking local connections. Sometimes, rebooting the router helps.
Watching videos via DLNA servers
Technology DLNA (Digital Living Network Alliance) is a standard for transferring media files over a local network. It's ideal for watching large, high-quality movies (4K, HDR) that take up a lot of space and aren't stored in the cloud.
To use this method, you need to install a server app on your phone, such as BubbleUPnP or VLC. After enabling the server in the app, your smartphone will appear in the "Connected Devices" or "Connection Manager" section on your LG TV. Once you open it, you'll see the file system and be able to play any video file.
The main advantage of DLNA is the ability to control playback with your TV remote. You can rewind a movie, change the audio track, or select subtitles without touching your phone. This is especially convenient when watching a movie with friends.
| Method | Quality | Phone addiction | Convenience |
|---|---|---|---|
| Screen Share | Depends on the signal | High (screen active) | Average |
| LG TV Plus | Good | Average | High |
| Chromecast | Maximum | Low (remote control only) | Very high |
| DLNA | Maximum | Low (start only) | High |
Troubleshooting connection issues
Despite the simplicity of the technology, users often encounter situations where devices can't see each other. First, check whether "Data Saver" or "Airplane Mode" is enabled on your phone while Wi-Fi is active. These settings can block the device search on the local network.
Another common issue is audio and video desynchronization. This often occurs when neighboring routers overload the Wi-Fi channel. Try switching your TV and phone to the 5 GHz frequency if your router supports dual-band operation.
If nothing helps, reset the network settings on your TV. In the menu Settings → All settings → Support → Self-diagnosis → Reset network settings You'll be able to clear your connection cache. You'll then need to re-enter your Wi-Fi password.
Frequently Asked Questions (FAQ)
Is it possible to mirror an iPhone's screen to an LG TV?
Yes, if your LG TV supports Apple AirPlay 2 (2019 models and newer). Simply open Control Center on your iPhone, select "Screen Mirroring," and find your TV. Older models will require third-party apps from the Content Store.
Why does video lag when streaming from a phone?
The main cause is low Wi-Fi speed or a large distance from the router. Slowdowns may also occur if the phone's processor can't handle real-time video encoding. Try lowering the video quality in the app settings or moving closer to the router.
Does Screen Share require internet access?
No, Miracast (Screen Share) doesn't require internet access; a local connection between the devices is sufficient. However, access to the global network is, of course, required to access online movie theaters (YouTube, Netflix).
How do I change the image resolution during broadcasting?
The resolution is usually adjusted automatically based on your TV's capabilities. You can change it manually in your phone's settings under "Cast" or "Wireless Display," if your smartphone model offers this option.
