Technology has transformed a smartphone into a powerful multimedia content control panel. Connecting a Xiaomi TV to a phone has opened up a wide range of functions, from screen broadcasting to smart home management. Users often underestimate the ability to connect mobile devices and large screens, limiting themselves to basic video viewing.
In this article, we will take a look at all the synchronization methods available, including wired and wireless solutions. You will learn how to configure Mi Remote, use Miracast and DLNA protocols, and how to solve typical connection problems.
It’s worth noting that the setup process may vary slightly depending on the version of the Android TV or PatchWall operating system installed on your device. However, the basic principles remain unchanged for the entire Xiaomi and Redmi line of equipment.
Equipment preparation and network inspection
Before you start setting up, make sure that both devices are in the same network environment, which is a critical step, as most errors are caused by the difference in network profiles, and make sure your router supports 5GHz Wi-Fi for high data rates.
Check to have your TV and smartphone connected to the same wireless network. If you have a dual-band router, make sure both are on the same frequency, although modern routers often combine networks under the same name.
💡
For stable 4K video broadcast, make sure the distance between the router and the TV is minimal and the signal is not overlaid by metallic structures.
Turn on the device detection feature on the TV. It is usually active by default, but some versions of Xiaomi software require manual activation of the standby mode of connection. This will take no more than a minute, but saves from long searches of devices in the list of available devices.
Broadcasting the screen through the built-in Mi Cast function
The easiest and fastest way to duplicate an image is to use native Mi Cast technology, which is built into the MIUI and HyperOS shell, making the process as easy as possible for owners of Xiaomi smartphones.
To start, open the notification curtain on your smartphone and look for the Broadcast or Cast icon. If the icon isn't in quick access, go to the connection settings. The TV should automatically appear in the list of available devices if it's online.
☑️ Pre-broadcast checks
Once you select a TV, you'll see a request on your smartphone screen to confirm your connection, click "Accept" on your TV remote, or confirm the action on your phone screen, and the image will instantly mirror, and you'll be able to control content from your smartphone.
⚠️ Note: When broadcasting the screen in horizontal mode, make sure that the phone is on autorotation, otherwise the image may be displayed with black fields on the sides.
Using the Google Home app to manage
Google's ecosystem offers a one-stop solution through the Google Home app, which is ideal if your TV is powered by Android TV. The app allows you not only to stream the screen, but also to control the media player by running videos directly from the TV's cache.
Install the Google Home app from the Play Market store and log in to your account.The program will automatically scan the network and find your Xiaomi TV.Click on the device icon to open the control panel.
From the menu that opens, select the option to Broadcast, which is often better than standard means, thanks to Google's protocol optimization, and especially for viewing photo albums or presentations.
Importantly, Google Home allows you to control the volume and basic functions of your TV if the devices are synced to one acca-unt, making your smartphone a full-fledged remote control with enhanced functionality.
Wired connection via HDMI and adapters
When wireless is unstable or requires maximum video transmission without compression, the best solution is a cable connection. You will need a USB-C to HDMI adapter. Not all smartphones support video output through the charging port, so check the specification of your model.
Connect the adapter to your smartphone and then connect it to your regular TV HDMI-Turn the signal source on the TV into mode. HDMI 1 HDMI 2, depending on the port used.The image should appear automatically.
| Adapter type | Support for video | Charging. | Compatibility |
|---|---|---|---|
| USB-C to HDMI | Up to 4K 60Hz | A separate port is required | Xiaomi's flagships |
| MHL adapter | Up to 1080p. | Through USB. | Old models |
| DisplayPort | Up to 8K. | Yes. | Rarely for phones |
The use of wires ensures no delays, which is critical for games or displaying dynamic content, and the wired connection does not depend on the congestion of the wireless channel by neighbors.
Setting up the remote Mi Remote on a smartphone
Infra-red port management is a special feature, with many Xiaomi and Redmi smartphones equipped with an integrated IR transmitter, and Mi Remote allows you to control your TV even without a Wi-Fi connection, emulating the signal of a conventional remote.
Run the app and select the type of device "TV." Follow the instructions on the screen, pointing the phone to the receiver of the TV signal. You will be asked to press several buttons to check the code. After successful verification, save the configuration.
What to do if the IR port is not working?
This method is especially useful if the standard remote is lost or discharged, and you get full access to the menu, audio settings and signal sources directly from the smartphone screen.
⚠️ Note: The IR remote does not require a Wi-Fi network to operate, but the phone must be in line of sight with the TV receiver, just like a conventional remote control.
Broadcasting multimedia through DLNA and third-party applications
If your goal is to play back video files stored in your phone’s memory, use the DLNA protocol. Unlike mirror display, here the TV decodes the video itself, which reduces the load on your smartphone and saves battery life.
Use player apps like VLC for Android or BubbleUPnP. Open the video file in the player, click the Translation button, and select your Xiaomi TV from the list of rendering devices.
The advantage of this method is that it can control playback, pause or rewind video without interrupting the stream. The TV buffers data, ensuring smooth playback even during temporary network speed surges.
💡
Use of the DLNA-Players significantly save battery power smartphone compared to full mirroring screen.
Some files may not play due to lack of support for codecs on the TV side, in which case it is recommended to use full-screen broadcasting described in the previous sections, since decoding will be done by the smartphone.
Solving Connection Problems
Despite the ease of setting up, users may find it difficult. Often, the TV simply “does not see” the phone in the list of available devices. First of all, check if the router is activated insulation of AP Isolation clients, which prevents devices from seeing each other on the local network.
If the connection is cut or the video is slowed, try restarting the router. It is also worth turning off the VPN on the smartphone, since virtual tunnels often change the network address, withdrawing the device from the local segment.
