Modern multimedia capabilities allow you to turn your Xiaomi smartphone into a powerful remote control and content source for your LG TV. Owners of Android devices, particularly those with MIUI and HyperOS, often look for ways to quickly display photos or videos on the big screen wirelessly. Wireless connection via Wi-Fi Direct or a local network is the most convenient and stable solution for everyday use.
The process of synchronizing gadgets from different brands has become significantly easier thanks to the introduction of universal broadcast protocols. You don't need to be a networking expert to establish communication between Xiaomi And LG Smart TVSimply perform a few sequential steps in the settings menus of both devices to unlock access to screen mirroring features.
In this article, we'll cover all current connection methods in detail, from built-in Android tools to dedicated manufacturer apps. You'll learn how to avoid common pairing errors, why devices may not recognize each other, and which router settings affect the stability of high-definition video streaming.
Equipment preparation and network requirements
Before starting the setup process, you must ensure that both devices are in good working order and ready to use. A fundamental condition for a successful connection is the location of the smartphone. Xiaomi and TV LG on the same wireless network. If you have a dual-band router, make sure both devices are connected to the same frequency, such as 5 GHz, to ensure better throughput.
Please pay attention to the software version installed on your TV. Outdated firmware webOS It may not support modern data transfer protocols or may operate with errors. We recommend checking for updates in the TV settings menu in advance and installing them if necessary.
⚠️ Important: If your router has a "Guest Network" feature, make sure AP Isolation is not enabled. Otherwise, devices, even on the same network, will not be able to detect each other for data transfer.
It's also worth checking your smartphone's battery. Wirelessly streaming videos or playing games consumes a significant amount of power, and a dead battery at a critical moment can interrupt your session. For extended viewing sessions, it's best to connect your phone to a power source.
Using the built-in "Cast" feature on Xiaomi
The fastest way to display an image from your smartphone on a TV screen is to use the standard Android operating system feature, which in the MIUI shell is called "Cast." This method is based on technology Miracast and does not require installation of additional software.
To activate the mode, open the notification shade on your Xiaomi phone by swiping down from the top. Find the icon labeled "Broadcast" (sometimes it's hidden in the second menu; you'll need to swipe left). If you can't find it, go to Settings → Connection and Sharing → Broadcast.
Once enabled, your phone will begin searching for available devices within range. Your LG TV may prompt you to allow the connection, which you'll need to confirm with the remote control. Some TV models require you to launch the app first. Screen Share or Device Connector.
☑️ Pre-broadcast check
Image quality directly depends on the strength of the wireless network signal. When using built-in streaming, latency can range from 0.5 to 2 seconds, which is normal for viewing photos but can be disruptive during fast-paced games. For a comfortable experience, it's important to ensure a strong router signal within the range of the devices.
Official LG ThinQ app for control
LG has developed its own app LG ThinQ, which provides advanced TV control capabilities from your smartphone. Unlike simple screen mirroring, this software allows you to use your phone as a full-fledged touchscreen control panel, changing channels, adjusting volume, and playing content from your phone's internal memory.
You can download the application from the official store. Google PlayAfter installation, launch the app and sign in to your LG account (or create a new one). Click the "Add Device" button, and the app will scan the network. Select your TV from the list and follow the on-screen instructions to complete the pairing.
| Function | Description | Requirements |
|---|---|---|
| Photo/video broadcast | Extracting media files from the gallery | LG ThinQ, Wi-Fi |
| Remote control | Full control of the TV interface | Bluetooth/Wi-Fi |
| Keyboard | Entering text from your phone to your TV | LG ThinQ |
| Monitoring | Checking the condition of filters and systems | TV support |
Pay special attention to the permissions the app requests during installation. For the remote control and file transfer functions to work correctly, you must grant access to local network, microphone (for voice search), and file storage. Without these permissions, functionality will be limited.
Streaming via Google Home and Chromecast
Many modern LG TVs support built-in technology Chromecast built-inThis allows you to stream content from apps that support this feature (YouTube, Netflix, Spotify) directly, without overloading your smartphone's processor. Control in this case is handled through the app. Google Home.
Install the application Google Home to your Xiaomi. Open it and find your TV in the list of devices. Click the TV icon, then select "Cast my screen." The image from your phone will appear on the big screen with minimal delay.
Why does the sound disappear during broadcasting?
Sometimes, when connecting via Chromecast, audio may only come through your phone. This can be resolved by selecting the audio output device in the app's settings (for example, in YouTube, click the Cast icon and select TV, not Phone).
The advantage of this method is that you can use your phone for other tasks while the video plays on your TV. Buffering occurs on the TV, saving your smartphone's battery and reducing the load on the processor.
Setting up a DLNA server for viewing media
If your goal is to view photos or videos stored in your phone's memory on a larger screen, the optimal solution is the technology DLNALG TVs have a built-in media player that can find servers on the local network.
You need to launch a server app on your Xiaomi smartphone. This could be the built-in file explorer with DLNA support or third-party software, such as BubbleUPnP or LocalCastIn the app, select the files you want to play and select your LG TV as the output device.
Unlike screen mirroring, DLNA only transmits a data stream, so the phone can be locked or used for calls without interrupting playback. Image quality remains at its best, as the file is decoded by the TV itself.
⚠️ Note: Video file formats must be supported by your TV. If the TV doesn't play the file, try using a third-party player on the TV itself or cast the entire screen via Miracast.
Troubleshooting connection and visibility issues
Despite the ease of setup, users may encounter a situation where their phone doesn't detect the TV. This is often due to router security settings or antivirus software. Make sure your router isn't set to restrict data exchange between clients (Client Isolation).
Another common cause is using different Wi-Fi frequencies. If your phone is connected to a 5 GHz network and your TV to a 2.4 GHz network, they may not be able to see each other unless the router is configured for proper roaming or network bonding. In this case, try connecting both devices to the same frequency.
It's also worth checking your smartphone's firewall settings. In some cases, MIUI's aggressive security settings can block incoming connections from the TV. Try temporarily disabling third-party antivirus software or changing the network profile to "Trusted."
Frequently Asked Questions (FAQ)
Is it possible to connect a Xiaomi phone to an LG TV without Wi-Fi?
Yes, this is possible using a USB-C to HDMI cable. You'll need a special adapter that supports video output (MHL or DisplayPort Alt Mode). Your phone will stream the image directly to the screen, but you'll still need a network connection to control Smart TV features.
Why is there a lot of lag when streaming a game?
Wireless protocols like Miracast have inherent latency. For high-reaction games (shooters, racing games), it's recommended to use a wired connection or stream via cloud services if supported directly by your TV.
Is there a loss of picture quality when broadcasting wirelessly?
When using compression protocols (for example, in some Miracast modes), a slight reduction in quality or compression artifacts may occur. Chromecast and DLNA technologies transmit the stream in its original quality, as the TV decodes the content itself.
Do all LG models support Smart View?
This feature is available on all LG Smart TVs (webOS). Older models with the NetCast operating system also support DLNA and Miracast, but may require manual activation in the network menu.
