Integrating a smartphone into the home theater ecosystem is standard for the modern user, but the process of pairing devices from different brands such as Xiaomi and LG sometimes raises questions. Owners of popular Chinese smartphones often face the need to bring photos, video from the gallery or even gameplay to the big screen, and standard methods here may differ depending on the version of the MIUI or HyperOS operating system. Understanding the principles of wireless protocols and wired interfaces avoids wasting time searching for non-working applications.
Modern televisions LG They're based on a webOS platform that has its own characteristics of interacting with external signal sources. TV, It doesn't always work with native Google Cast features without pre-configuration, which requires the user to know alternative ways, such as Miracast technology or proprietary utilities. DLNA-servers turn this process into a simple operation, accessible even to an inexperienced user.
In this guide, we will take a look at all the current ways to connect your gadget to your TV display, paying special attention to hidden settings and potential software conflicts. We will look at both wireless methods that ensure freedom of movement and wired solutions for those who are the best picture quality without delay. Deep dive into the technical nuances will help you set up a stable connection the first time.
Device preparation and network settings
The first and most critical step is to ensure a single network environment for both devices.The Wi-Fi router should broadcast the signal at a frequency supported by both gadgets, with the desirable use of the 5 GHz band to transmit high-resolution video without artifacts.Make sure that the Xiaomi smartphone has turned off mobile Internet during settings so that the system does not try to shift traffic priority.
On an LG TV, you need to activate the external connection mode, as by default some models can block incoming requests for security purposes. Go to the settings menu, select General, then go to Device Management or Connections. Here you need to find the Screen Share option (or Translation in new versions of webOS) and switch the slider to the active position, making the TV visible for search.
⚠️ Note: If your router supports customer isolation (AP Isolation, devices can be on the same network but not see each other. To successfully connect, this feature must be temporarily disabled in the router settings.
Check the software version on both devices, as legacy Wi-Fi module drivers may not support new encryption standards or media content transfer protocols. On Xiaomi, this is done via Settings → About Phone → MIUI version, and on TV via Settings → All Settings → Support → Software update. Topical patches often contain patches for compatibility with popular smartphone brands.
☑️ Checking before connection
Wireless connection through the built-in function "Translation"
The easiest and fastest way to do this, without third-party software, is to use Miracast technology, which is called Translation in the MIUI shell and the new HyperOS, and is hidden in the notification menu or connection settings, and the algorithm is to create a direct Wi-Fi Direct connection between the phone and the TV, bypassing the router to transmit video stream, which reduces the load on the local network.
To activate, lower the notification curtain on your Xiaomi smartphone and find the Translation icon. If it's not on the main screen of the panel, click on a pencil or three menu editing dots and add this widget. Once turned on, you'll start looking for available devices, and in a few seconds your LG TV with the corresponding model number should appear on the list.
- 📱 Click on the “Translation” icon in the notification curtain of your smartphone.
- 📺 Make sure your TV is running Screen Share or the feature is active in the background.
- 🔗 Choose your name. LG TV from the list of available devices.
- ✅ Confirm the connection on the TV screen if a request for permission appears.
It is worth noting that when using this method, the phone screen is completely duplicated on the TV, including system notifications and sounds. Input lag can be noticeable in dynamic games, so this method is ideal for viewing photos, videos from the gallery or presentations, but not for competitive gaming.
💡
If the device search does not give results, try rebooting the Wi-Fi module on your phone: turn it on and off in the settings, then repeat the search.
Use the LG TV Plus app for advanced features
Official annex LG TV Plus (previously known as LG ThinQ) provides a deeper level of integration, allowing not only to broadcast the screen, but also to use the smartphone as a remote control with advanced features. After installing the application from Google Play, you need to go through the pairing procedure, scanning. QR-code on a TV screen or by finding a device on a local network.
The app’s functionality allows you to display gallery content, video files, and even run certain apps on your TV directly from your smartphone. Unlike simple mirror transmission, it uses the DLNA protocol, which transmits the media file itself rather than the picture from the screen, saving your phone’s battery power and allowing you to use the gadget for other tasks while watching.
Inside the app, there is a separate content management tab where you can create playlists and customize playback order, which is especially useful when organizing home movie watching, when the phone acts as a media library. The application interface is adapted for different versions of Android, ensuring stable operation even on the newest Xiaomi models.
| Function | The Translation Method (Miracast) | LG TV Plus (DLNA) appendix | Google Home (Cast) |
|---|---|---|---|
| Type of transmission | Screen mirroring | Broadcasting the file | Streaming |
| Use of the telephone | You can't use it. | We can use it. | We can use it. |
| Video quality | Depends on the Wi-Fi signal. | Maximum (original) | Depends on the Internet. |
| Battery consumption | High-pitched | Low. | Medium. |
Broadcasting via Google Home and Chromecast
Many modern LG TVs support the built-in Google Cast platform, which allows you to use the standard Android mechanism to display images. To do this, the Xiaomi smartphone must have a Google Home app, which serves as a smart home control center and entry point for broadcasting.
Once logged in, find your TV in the device list, and click on it and you'll see a "Cast screen" button, which is highly stable and low-power, because it uses Google's optimized codecs, but requires that the content or application support Cast.
If you don’t have built-in Chromecast support in your TV model, buying a Chromecast external console or using an Android TV via HDMI can solve the problem. In this case, the Xiaomi phone will see the console as a separate device, and the setup process will be identical to working with the built-in module.
⚠️ Note: When streaming through Google Home, image quality is directly dependent on your Internet connection speed, not just the speed of your local network, as streaming often goes through the cloud.
Wired connection through HDMI-adapter
For situations where you want maximum image quality without compression and delay, or when the wireless network is overloaded, the only right solution is cable. HDMI-Exit will require a special adapter. USB-C to HDMI. It is important to note that the port USB The phone should support the standard MHL DisplayPort Alt Mode.
Not all Xiaomi models support video output via USB. Flagship series like Xiaomi Mi, some Redmi Note Pro series models and Black Shark usually have this feature. Budget models can be limited to data transfer and charging only, so it's worth checking the specification of a specific processor (SoC) before buying an adapter.
Checking for HDMI support:
1. Connect the adapter to the phone.
2. Connect the HDMI cable to the TV.
3. switch the signal source to the TV to the appropriate HDMI port.
4. If the image appears, your port supports video output.The advantage of the wired method is the absence of dependence on interference in the air and a stable picture in 4K resolution. In addition, the phone in this mode can often be charged from an external power source if the adapter has an additional USB port for power, which solves the problem of fast battery discharge during active operation.
Why is there no image when connecting the cable?
Addressing common problems and conflicts
Despite the standardization of processes, users often face situations where devices can not see each other or the connection is constantly broken. One common reason is the use of different Wi-Fi frequencies: if the phone is running on a 5 GHz network and the TV is connected to 2.4 GHz, the router can isolate them from each other, especially when the “Smart Connect” feature is turned on, which connects networks under one name.
Problems can also arise from settings on a firewall or antivirus software installed on a router or smartphone, and the multicast traffic protocols required to detect DLNA and Miracast devices are sometimes blocked as suspicious activity, in which case the creation of a guest network or temporary shutdown of strict packet filtering helps.
- 🔄 Reboot your router, phone, and TV – it solves 80% of cache problems DNS.
- 📶 Try switching your phone to a 2.4GHz network if 5GHz is unstable.
- 🔒 Turn it off. VPN on a smartphone, as it changes the network route and hides the device.
- 📲 Update the Translation or Google Home app through the Play Market Store.
If there is an image but no sound, check the audio output settings in the app itself that you are broadcasting. Some video codecs may not be supported by the TV, in which case the sound remains on the phone. In the Xiaomi settings in the Sound and Vibration section, it is also worth checking whether mono-sound or other special effects that conflict with external output are activated.
💡
Connection stability depends on the quality of the router: older models may not be able to handle high-resolution video streaming and multiple devices running simultaneously.
