With technology, you can turn your smartphone into a powerful multimedia content control panel, and Xiaomi’s LG-Link is working perfectly here. Many users are wondering how to bring an image from a small screen to a large panel to watch movies, play games or show photos. Fortunately, the Android ecosystem and the webOS operating system installed on LG TVs offer many options for this task.
There are several proven synchronization methods, ranging from simple wireless protocols to physical cable connection. The choice of the specific method depends on your smartphone model, the MiUI or HyperOS firmware version, and the year of the TV release. In this article, we will discuss each option in detail so that you can enjoy the content in the maximum quality without unnecessary delay.
Before you start any manipulation, make sure that both devices are working correctly and have up-to-date software. Often, connection problems arise precisely because of incompatibility of data protocol versions. We will look at both standard system tools and third-party applications that can be useful in difficult cases.
Preparing devices for synchronization
The foundation of a successful connection is the correct preconfiguration of the equipment. The first and most important condition for most wireless methods is that both gadgets are on the same local network. The router should give a signal at 2.4 GHz or 5 GHz, and it is desirable that both devices be connected to the same frequency to avoid addressing conflicts.
On an LG TV, you need to activate the external signal reception function. To do this, press the Settings button on the remote control. In the menu that opens, find the section responsible for connecting mobile devices. In older models, this may be called Smart Share, and in new ones, Screen Share or simply Connect to your phone.
Xiaomi’s smartphone should also check Wi-Fi settings. Sometimes the system may suggest using mobile traffic for certain services, which will block the local connection. Make sure that the power saving mode does not restrict the background operation of network services, as this can interrupt the process of finding devices.
⚠️ Note: If your router supports customer isolation (AP Isolation, turn it off in the router settings. This feature by default prevents devices within the same network from "seeing" each other, making wireless connectivity impossible.
☑️ Checking before connection
Broadcasting through the built-in function "Translation"
The easiest and fastest way to do this without having to install any additional software is to use the native Miracast feature, which is called Translation in the MIUI and HyperOS shell, which allows you to duplicate your smartphone screen on your TV in real time with minimal latency, and it works at the system level, so the quality of the image depends on the power of the Wi-Fi module.
To start the process, lower the notification curtain on your phone and find the Broadcast icon. If it's not on the first screen, click three dots or an edit icon to add the widget to the active menu. Once you activate the search, the phone will start scanning the network for available displays.
When the name of your LG TV appears on the list, click on it. You may see a request for permission to connect on the TV screen — confirm it with the remote control. From now on, everything that happens on the smartphone screen will be displayed on a large panel, which is convenient for watching photos, videos from the gallery or navigating maps.
- 📱 Go to Settings. → Connection and sharing → Broadcasting.
- 📺 On TV. LG Open the Screen Share app (unless it is automatically enabled).
- 🔗 Select your TV from the list of found devices on your phone.
- ✅ Confirm the connection on the TV screen if a request appears.
It should be noted that using this method, the smartphone screen must be unlocked. If you turn off the phone screen, the broadcast will most likely be interrupted, as the system will go into sleep mode, and it is also possible to heat the device with prolonged operation, since the process of encoding the video stream requires the resources of the processor.
💡
To reduce latency (lags) during games via broadcast, try to be closer to the router or use a 5 GHz frequency that is less loaded by neighboring networks.
Use of the LG ThinQ application
The official LG ThinQ app (formerly LG TV Plus) provides a deeper level of integration than a simple screen broadcast, allowing not only displaying an image, but also using the smartphone as an advanced remote, transferring files and running content directly from the phone’s memory through the TV interface, which is especially true for owners of older Xiaomi models, where the standard broadcast function can work unstablely.
Download the app from Google Play Market and install it. When you first start it will ask for permissions to access the LAN and geolocation, which is necessary to find equipment in the house. Follow the on-screen instructions to add your TV to the list of devices. The pairing process can take a couple of minutes.
Once you have successfully added a TV, select it from the list. In the app interface, you will be interested in Screen Translation or Phone Screen. Unlike Miracast, the connection is established through the manufacturer's servers or a more stable local protocol, which sometimes gives a better picture with a weak Wi-Fi signal.
| Function | Built-in "Translation" | LG ThinQ Application | Google Home |
|---|---|---|---|
| Stability | Medium | Tall. | Tall. |
| TV administration | No. | Yeah, remote. | Partially. |
| File transfer | No. | Yes. | No. |
| Delay. | Low. | Medium | Low. |
An important advantage of LG ThinQ is that you can play video on your phone, switch it to TV, and go into the kitchen using the phone as a remote control, but for all functions, the TV must also be registered with LG and have an account.
Why can't the app see the TV?
Broadcasting via Google Home (Chromecast)
Many modern LG TVs have built-in support for Google Cast (Chromecast built-in), which allows you to stream content from applications that support this feature (YouTube, Netflix, Kinopoisk, Google Photos) directly to the TV, bypassing the smartphone screen, in which case the phone acts only as a remote, and video streams directly from the Internet to TV, which saves battery.
To use this method, make sure that the phone has Google Home.If Chromecast support is not built-in in your TV model (usually models before 2018-2019), the feature can be added by connecting an external Chromecast or Android Box to the HDMI port.
Open an app that supports broadcasting (like YouTube) and click on the Wave rectangle icon (Cast). Select your TV. The video image will instantly appear on the screen, and on the phone you can adjust the volume, rewind or pause, and answer calls without interrupting your viewing.
- 🌐 Make sure your TV is displayed in the Google Home app.
- ▶️ Open content in a supportive app (YouTube, Netflix).
- 📡 Click the broadcast icon and select the device LG.
- 🎬 Enjoy watching by using your phone as a remote control.
The main advantage of the method is independence from the power of the smartphone. Even if the phone runs out or you leave the Wi-Fi zone (in some cases), the video will continue to play, because buffering occurs on the TV side, and the image quality is often higher than with direct duplication of the screen.
💡
Using Google Cast saves up to 40% of your smartphone battery power compared to a full screen broadcast (Miracast) as the phone’s processor does not encode the video stream.
Wired connection via HDMI and USB-C
For those who require maximum image quality without compression and delays, or if the Wi-Fi network is unstable, there is a wired option.Modern flagships Xiaomi (Mi series, Xiaomi Pro, some models Redmi Note) are equipped with a port. USB Type-C with DisplayPort Alt Mode, which allows you to transmit video directly through the adapter to the Alt Mode. HDMI.
You'll need a dedicated USB-C to HDMI adapter. Just insert the narrow end into the phone, and connect the HDMI cable to the TV. Switch the TV signal source (Input or the button with a square and arrow) to the appropriate port. The image will appear automatically, often in high 4K resolution, if it supports cable and TV.
⚠️ Note: Not all Xiaomi phones support video output via USB-C. Budget models (often the Redmi series with Snapdragon processors) 4xx/6xx Or older Helio) may have a port only for charging and data transfer, but not video.
If your phone doesn't support video output, you can try USB connectivity, but the functionality is limited. The TV can see the phone as an external flash drive, in which case you can open the file manager on TV (LG Content Store -> Media) and run video files stored in the memory of the smartphone. This is not a live broadcast, but only read files.
The advantage of wired technology is that it doesn't have lags, which is critical for games or presentations. It's transmitted in its original resolution without the compression artifacts that are common in wireless protocols. However, the length of the cable limits mobility, and the phone will run out if it's not connected to an additional power source (some hubs have charging input).
Solving Typical Connection Problems
Even if all instructions are followed, there can be technical difficulties: often users are faced with a situation where the phone sees the network but does not see the TV, or the connection is constantly broken, and in most cases the problem lies in the settings of the router or the cache of network services.
If the devices do not find each other, try to restart the router by turning it off the socket on the 10-15 Also on TVs. LG The “Quick Start” function is used.+), You need to switch it off sometimes. Try turning it off in the TV settings (General). → Additionally. → Quick start, turn off the TV completely with the power button and turn it back on, and it reboots the webOS operating system, not just puts it to sleep.
Another common problem is desynchronizing audio and video, which is treated by updating the TV firmware through the Support → Software Update menu. Also check if the phone is not on Do Not Disturb mode, which can block system sounds or connection notifications.
