With modern multimedia capabilities, you can turn any smartphone into a powerful home theater remote control. Users often wonder how to connect your phone to an lg smart TV to stream content to the big screen. This action opens up access to high-resolution movies, photo galleries and even mobile games without the limitations of a small display. The setup process is simple enough and does not require deep technical knowledge, if you follow proven algorithms.
Xiaomi has introduced advanced tools for interacting with external displays to the MIUI shell and the new HyperOS. In turn, the LG webOS platform supports basic wireless data protocols. It is critical to successfully connect both devices on the same LAN, although there are alternative methods for connecting without a router. In this article, we will discuss in detail all methods of synchronization, from standard functions to specialized utilities.
Network requirements and preparatory settings
Before starting the procedure, make sure that your home network infrastructure is ready to transmit heavy video streams. The wireless connection should be stable, as any breaks will lead to image delays or sound dissynchronization. The ideal option is to use a router operating in the 5 GHz band, which provides higher bandwidth compared to 2.4 GHz.
Both devices, a smartphone and a TV, must be connected to the same Wi-Fi hotspot. If you have a dual-band router, make sure the gadgets are not spread across different frequency bands, unless the router combines them into a single network with the same name. SSID. Sometimes it helps to reboot the router to clear the connection cache and update. IP-address.
⚠️ Attention: Using a guest Wi-Fi network often blocks the ability to detect devices with each other due to customer isolation.
Check the software's relevance too. On LG TV, go to the settings and find the system update section to rule out known bugs. On Xiaomi, it's also advisable to have the latest firmware version, as engineers are constantly optimizing the Wi-Fi Display module.
Broadcasting the screen through the built-in function of Xiaomi
The fastest way to display an image is to use the native screen transfer function, which can be called differently on Xiaomi smartphones depending on the version of the shell: “Translation”, “Wireless Monitor” or “Cast”, a method based on the Miracast protocol, which is supported by most modern LG TVs without the need to install additional software.
To activate the function, lower the notification curtain and find the corresponding icon. If it is not on the first screen, click on the edit button (usually a pencil or three dots) and drag the widget to the active area. Once turned on, an automatic search for available devices within network range will begin.
- 📱 Open the control panel and select “Translation».
- 📺 Turn on the TV. LG And make sure it's active.
- 📡 Wait for the name of your TV to appear on your smartphone.
- 🖥️ Click on the TV name to establish the connection.
Once paired, the phone's screen is completely copied to the TV display, in which the orientation of the image will change automatically when you turn the smartphone. The picture quality depends on the power of the Wi-Fi signal; if there is interference, you can see artifacts of compression or micro-latency of the cursor.
💡
If the broadcast is delayed, try lowering the video resolution in the broadcast settings or bringing the router closer to the TV to improve the signal.
Using the LG TV Plus app to manage
The official LG TV Plus app (formerly known as LG ThinQ) provides a deeper level of integration than a simple screen broadcast, allowing not only media output, but also control the TV as a remote, and use the Screen Share feature with additional settings. This software is available on Google Play Market and optimized to work with the LG ecosystem.
Once the app is installed, it needs to register the device, and it will find the TV on the network and request permission to connect, the confirmation code of which will appear on the TV screen. Unlike the standard Miracast, it is possible to transfer files from the internal memory of the phone without mirroring the entire interface.
In the application interface, select Screen Share or Phone Translation, where you can choose to view photos, videos or music, and the TV media server will have direct access to the smartphone file system, allowing you to play content in original quality without the compression that is characteristic of streaming an entire screen image.
| Function | Standard broadcasting | LG TV Plus |
|---|---|---|
| Image quality | Depends on the Wi-Fi signal. | High (flowing) |
| TV administration | No. | Full (remote) |
| Working in the background | No (screen on fire) | Yes (for media) |
| Energy consumption | High. | Average. |
Google Cast and Chromecast protocol built-in
Many of LG’s current TVs feature built-in support for Google Cast (Chromecast built-in), which allows content to be streamed directly from apps like YouTube, Netflix or Chrome without being broadcast by the system, a method that is most effective for watching online video, as the workload is on the TV’s processor rather than the smartphone.
To use this method, open a supported app on your Xiaomi phone. Find a broadcast icon (rectangle with waves in the corner). From the list of devices, select your LG TV. The video stream will be buffered directly from the Internet to the TV, saving the phone's battery power and allowing you to use the gadget for other tasks.
⚠️ Note: If the Cast icon doesn’t appear, make sure the app you’re using supports this technology and that the appropriate profile or receiver app is running on the TV.
The advantage of this approach is that you can control playback from your phone, pause, rewind or change the volume without getting out of the sofa, and the picture quality with this connection is usually more stable, because it uses an adaptive bitrate that adjusts to the speed of the Internet.
☑️ Checking before connection
Wired connection via USB-C to HDMI adapter
For users who want maximum image quality without delay and compression, wired connection will be the best solution. However, there is an important caveat: not all Xiaomi smartphones support video output via a USB Type-C port. Video Alt Mode is present mainly in the flagship models of the Mi series, Xiaomi (digital series) and some Black Shark models.
If your phone supports video output, you will need a USB-C to HDMI adapter. One end is inserted into the smartphone, and the other connects an HDMI cable that goes to the LG TV. After connecting, you need to switch the signal source on the TV to the appropriate HDMI 1 or HDMI 2 port.
The image will appear automatically. The phone's settings may display a resolution and refresh rate settings menu. Only phones with a USB 3.1 port (or higher) that support DisplayPort Alt Mode are capable of transmitting video via cable. Redmi and POCO low-end models often lack this hardware capability and the cable will not work.
How to check video output support without cable?
Solution: The phone doesn't see TV
One of the most common problems is when device searches fail, often because of router security settings or a temporary failure of UPnP network protocol. Try temporarily shutting down mobile internet on your smartphone, leaving only Wi-Fi, so that the system does not try to prioritize mobile traffic.
It's also worth checking the firewall settings on the router. Sometimes antivirus protections or parental controls can block local interaction between devices. Try temporarily disabling such functions to test the hypothesis. Rebooting the Wi-Fi module on both devices (off-off-on) also often solves the problem of "hang" search.
- 🔄 Reboot your router, phone and TV at the same time.
- 📶 Make sure that the “guest network” mode is not turned on».
- 🛡️ Check if the antivirus is blocking local connections.
- 📲 Update the Translation or Mi Remote app».
If nothing helps, reset the network settings on your phone. Note that this action will remove saved passwords from Wi-Fi, but often eliminates the deep conflicts of network drivers.
💡
90% of connection problems are solved by restarting the router and checking that both devices are in the same frequency range (2.4 or 5 GHz).
