Modern Xiaomi smartphones and LG TVs provide users with ample multimedia entertainment. Often, there is a situation when the screen of the gadget is not enough to watch a movie, a presentation or a photo shoot with friends. Fortunately, wireless data technology allows you to broadcast a picture in seconds, which eliminates the need to search for cables or transfer files through flash drives.
There are several proven methods of synchronizing devices, each with its own characteristics. The choice of the specific method depends on the model of your TV, the version of the MIUI or HyperOS operating system, as well as whether you have access to a Wi-Fi network. In this guide, we will discuss all the current options in detail so that you can choose the most suitable for your situation.
Consider both standard Android features and customized applications from manufacturers, and learn how to set up mirrors without delay and what to do if devices can’t see each other.
Use of the built-in Translation function in MIUI
The easiest and fastest way to display the screen is to use the standard Android feature, which is called Translation in the MIUI shell, which is based on Miracast technology, which allows you to transfer video and audio in real time.
Before starting the procedure, make sure that your Xiaomi smartphone and LG TV are connected to the same Wi-Fi network. This is a critical condition without which devices will not be able to detect each other on the local network. If the router gives signals at 2.4 and 5 GHz with different names, connect both gadgets to one of them.
To start the process, follow the following steps:
- 📱 Open the notification curtain on your phone and find the “Translation” icon (or “Cast” icon»).
- 📺 Turn on Screen Share on your TV LG via the Home menu or the input button.
- 🔗 Click on the name of your TV in the list of available devices on your smartphone.
- ✅ Confirm the connection on the TV screen if you receive a request for access permission.
Once you pair the phone successfully, it will show up on the big screen, and it's worth noting that the quality of the image may depend on the speed of the wireless connection, and if you notice a desynchronization of the sound or video, try to zoom in on the router or reduce the load on the network.
💡
For stable 4K video transfer, use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) standard.
Setting up LG TV and receiving the signal
LG TVs run on webOS, which has its own external reception features, and unlike some other brands, it may require manual idle operation before searching for a device, which ensures security and prevents accidental connections to your TV.
On LG's remote control, find a button with a picture of a house or gear. In the menu that opens, select "Screen Share" or "Connect to a mobile device." In new models, this feature can be hidden in the folder "My apps" or on the start bar.
There are several modes of operation of the receiver that affect the behavior of the device:
- 🖥️ Three screens: allows you to broadcast the image, while retaining access to other TV features.
- 🔒 Smartphone only: TV blocks remote control and controls only signal from phone.
- 📡 All devices: open access mode for any gadgets on the network.
⚠️ Note: If the TV doesn’t appear in the list of available devices, try restarting the Wi-Fi module in the router settings or temporarily disabling the Customer Isolation feature» (AP Isolation) in network security settings.
In some cases, the system may request a webOS software update to allow data protocols to work correctly. The Miracast protocol, used by default, does not require Internet access, but an active LAN between devices is required. Once set up, the TV will remember the phone, and the reconnection will occur automatically.
Application of the official LG TV Plus application
If standard screen broadcasting is unstable or you want to get advanced control functionality, use the official LG TV Plus app. This software turns your smartphone into an advanced remote and allows you to stream media files directly, bypassing the mirror mode, which is especially useful for viewing photos and videos from the gallery.
You can download the app from the Google Play Store. After installation, start the program and follow the instructions on the screen. The app automatically scans the network and offers a list of compatible TVs. Select your LG model from the list.
The main features of the annex include:
- 🎮 Controlling Magic Remote cursor via touch screen.
- 📂 Broadcasting photos, videos and music from the phone’s memory.
- ⌨️ Enter text from the smartphone keyboard to search in YouTube or browser.
Unlike full screen broadcasting, this method only transmits media content, which saves battery power on your smartphone. In addition, you can continue to use other apps on your phone while the movie is playing on the TV. To start the broadcast, select a file in the app gallery and press the output button.
☑️ Checking before connection
Broadcasting via Google Home and Chromecast
Many modern LG TVs have built-in support for Chromecast built-in technology, which allows you to stream content from applications that support this feature (YouTube, Netflix, Spotify), directly, without loading on the phone's processor.
To get started, make sure your smartphone has Google Play services installed. Open the Google Home app and find your TV in the device list. If the TV isn't found, click the + button in the corner of the screen and select Set up your device -> New device.
The adjustment process is as follows:
- Launch the Google Home app on your Xiaomi phone.
- Click on the icon of your TV in the main menu.
- Select the option “Cast my screen”.
- Confirm the action by clicking “Translate screen” in the pop-up window.
The advantage of this method is high quality transmission and minimal latency, video stream is transmitted directly from the server to the TV, and the phone acts only as a remote control, which is ideal for watching online cinemas in high resolution.
What to do if the broadcast button is not active?
Connecting via HDMI adapter
When wireless connectivity is impossible due to weak signal or lack of Wi-Fi, cable connectivity comes to the rescue. Since Xiaomi smartphones do not have a full HDMI port, you will need a special USB-C to HDMI adapter, which provides maximum stability and image quality.
It is important to consider that not all phone models support USB video output.MHL or DisplayPort Alt Mode feature should be stated in your device specifications.Flagship models usually support this option, while budget segments may not have this option.
The connection scheme looks like this:
- 🔌 Connect the adapter. USB-C smartphone-charging connector.
- 📺 Put the cable in. HDMI Adapter and free port of the TV LG.
- 📺 Press the Input button on the TV remote and select the appropriate port. HDMI.
- 📱 Image should appear automatically; if not, check the output settings in the Screen section».
⚠️ Note: When using cheap adapters without additional power, the phone may quickly discharge or not give a signal (USB-PD).
The table of comparison of connection methods will help to determine the choice:
| Method | Quality. | Delay. | Dependence on Wi-Fi |
|---|---|---|---|
| Broadcast (Miracast) | High. | Medium | Required. |
| LG TV Plus | Average. | Low. | Required. |
| Chromecast | Maximum. | Minimum | Required. |
| HDMI cable | Maximum. | Absent. | Not required |
