Modern technologies make it easy to display images from your smartphone on a large screen, turning your mobile device into a powerful multimedia center. Owners of the bundle Redmi And LG We often need to display photos, play videos, or even play games on a widescreen TV. Fortunately, this doesn't require complicated cables or adapters, as both systems support advanced wireless data transmission standards.
The synchronization process is based on the use of a local network. Wi-Fi, which ensures high signal transmission speeds. This means your router becomes the central hub, uniting your devices into a single ecosystem. Proper configuration will allow you to enjoy high-definition content without lag or compression artifacts.
In this article, we'll take a detailed look at all available methods, from built-in Android features to third-party apps. You'll learn how to troubleshoot common connection issues and what settings are hidden in the developer menu. A deep understanding of how it works Miracast And DLNA will help you avoid common mistakes when trying to pair for the first time.
Basic wireless connection technologies
Before setting things up, it's important to understand the terminology, as different applications use different data transfer protocols. The most common standard for image streaming is Miracast, which allows you to mirror your smartphone's screen in real time. This protocol works directly between devices or through a router, ensuring minimal signal latency.
To play media content such as video files or music, technology is often used. DLNAIt doesn't require duplicating the entire screen, but simply transmits a data stream to the renderer, which is the TV. This allows you to control playback from your phone while the TV simply displays the image, saving battery life and processor resources.
LG uses its own platform webOS, which has built-in support for most popular protocols. Smartphones Redmi work on the basis of the shell MIUI (or HyperOS), where the broadcast functions may be named differently depending on the firmware version.
- 📺 Miracast — technology for full screen duplication (broadcasting everything that happens on the phone).
- 🎵 DLNA — a protocol for streaming media files without duplicating the interface.
- 🌐 Chromecast built-in — Google technology for broadcasting content from applications directly to TV.
It's important to understand that connection quality directly depends on the power of your router and interference in the air. If the network is overloaded, you may experience brief connection interruptions or reduced picture quality.
Preparatory stage: setting up the network and devices
The foundation of a successful connection is a properly organized local network. The first and most critical condition is that both devices are on the same subnet. This means that Redmi, And LG Smart TV must be connected to the same router.
⚠️ Note: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, make sure both devices are connected to the same network. Some older TV models may not see smartphones on the 5 GHz network due to driver issues.
Check that Wi-Fi is enabled on both devices. On TVs, this is usually done via the gear button or through the menu. All Settings → NetworkOn a smartphone, simply swipe down from the top to access the notification shade.
Make sure that on your TV LG The external device detection function is enabled. In the menu webOS This option is often called "Mobile Device Connect" or "Screen Share." Without this mode enabled, the TV will be invisible to search engines.
☑️ Check before connection
Sometimes antivirus software or router firewall settings can block local connections between devices. If you're using complex corporate settings or a guest network, try switching to your main home network.
Method 1: Broadcast via built-in Screen Share (Miracast)
The easiest way to display an image is to use the native function Miracast, which is built into the shell MIUIOn TVs LG This technology is often implemented through an app. Screen ShareOpen it on your TV to start connection standby mode.
On a smartphone Redmi The option may be called "Broadcast," "Wireless Monitor," or "Cast." You can find it in the notification shade (the button may be hidden in the button editing menu) or via the path Settings → Connection and Sharing → Broadcast.
Once the search is activated, the phone will begin scanning for available devices. When yours appears on the list LG TV, click on it. A connection confirmation prompt may appear on the TV screen, which you'll need to accept with the remote.
| Parameter | Redmi phone | LG TV |
|---|---|---|
| Function name | Broadcast / Cast | Screen Share |
| Connection type | Automatic | Waiting / List |
| Delay | Minimum | Depends on the router |
| Sound | Broadcast on TV | Playing back |
If the image appears but the sound remains on the phone, check the audio settings in the broadcast menu. Some models Redmi allow you to choose where to output the audio stream.
Method 2: Using the LG TV Plus app
If standard methods don't work reliably, it makes sense to use the official application from the TV manufacturer. LG TV Plus (formerly known as LG Remote) provides advanced control functionality and a stable connection.
Download the app from Google Play to yours RedmiOnce launched, the program will prompt you to find the TV on the network. Make sure you've granted all necessary permissions to access the local network, otherwise the app won't be able to detect the device.
Once paired (by entering the PIN code displayed on the TV screen), you'll have full control over your phone. The app menu features a "Screen Casting" or "Smart Share" button, which initiates the mirroring process.
- 📱 Mouse control — the ability to control the cursor on the TV screen via the phone's touchscreen.
- 📁 Media Center — convenient access to photos and videos in the phone’s memory for display on the screen.
- ⌨️ Text input — typing text for YouTube or browsers using your smartphone keyboard.
This app is especially useful if the standard Miracast protocol causes audio and video to become out of sync. The app uses its own buffering algorithms, which can smooth out any stuttering.
What should I do if the app doesn't detect the TV?
Make sure the app has permission to access the local network. On Android 10 and above, you'll need to grant this permission manually upon first launch. Also, try restarting your router.
