How to sync your Xiaomi phone and TV: the complete guide

Modern Smart TV is no longer just a screen for watching cable TV, becoming a multimedia center that requires constant interaction with mobile devices. Owners of the Xiaomi ecosystem often wonder how to best connect their smartphone with the TV to broadcast content, manage systems or simply display photos on the big screen. The synchronization process opens up access to many hidden functions that are not available with standard remote use.

There are several proven ways to establish a stable connection, each with its own technical features and application scenarios: you can use embedded Mi Play protocols, third-party apps or standard Android operating system features. The choice of the specific method depends on your TV model, firmware version and what content you plan to broadcast.

In this guide, we will take a look at all the current connectivity methods, from wireless technologies to wired solutions for professionals. It is important to understand that for all functions to work smoothly, both devices must be on the same local Wi-Fi network. Ignoring this basic requirement is the most common cause of errors when trying to start broadcasting.

Preparation of equipment and network for stable operation

Before you start setting up software interfaces, you need to make sure that the physical infrastructure of your home network is correct. The quality of the video stream in high resolution depends on the channel bandwidth and no interference. The ideal option is to connect both devices to a router operating in the 5 GHz band.

Check that your Xiaomi Mi TV or Redmi Smart TV has enabled device detection. Often, this option can be deactivated by default for privacy or energy saving purposes. Go to the settings menu and find the section responsible for network connections or external devices.

• 📡 Make sure your smartphone and TV are connected to the same Wi-Fi network (the name of the network must be the same).
• 🔌 Turn it off. VPN-services on a mobile device, as they can hide local IP-address and block search.
• ⚡ Restart your router if the network is unstable or the list of available devices is not updated.
• 📱 Update Google Home or Mi Remote to the latest version through the Play Market Store.

⚠️ Note: If your router gives away two networks with the same name (2.4 GHz and 5 GHz) but smartphones see them as one, try temporarily splitting them or force one of the devices to 5 GHz for better performance.

Broadcasting the screen through the Mi Cast and Chromecast function

The most common and commonly used method is Screen Mirroring, which is often implemented through the built-in Mi Cast protocol, which is based on Google technology, which allows you to stream images from your smartphone in real time, which is ideal for showing presentations, games or watching videos from applications that do not have native support for Smart TV.

To activate the mode on the TV, you need to find the Mi Cast application in the list of installed programs or call it through the signal source menu. On some models with the PatchWall shell, you just click the menu button on the remote and select Translation.

On the smartphone side, the action algorithm depends on the MIUI shell or HyperOS. Usually, there is a ready-made "Translation" or "Cast" label in the notification curtain. If it is not, go to the settings, select "Connected Devices" and click "Translation." The phone will start searching for available displays on the network.

It should be noted that when using this method, the smartphone can heat up and the battery will be consumed faster than usual, this is due to the fact that the device’s processor constantly encodes the video stream and transmits it over the network.

Using the Mi Remote application for management

If your goal is not to stream a picture, but to manage your TV comfortably, Mi Remote will be an indispensable tool, transforming your smartphone into an advanced remote with voice and keyboard support, and this is especially true when you need to type in a complex Wi-Fi password or a YouTube search query, which is inconvenient to do with a standard remote.

To get started, download the official Mi Remote app (or MI Remote) from the app store. Launch the program and add a new device by selecting the type "TV" It's going to offer multiple code options or perform automatic searches. Follow the instructions on the screen, press the buttons to check the connection.

The app goes beyond just switching channels, you can access the TV file system, you can install apps remotely, and even use your smartphone microphone to search voice on a large screen, and it creates a sense of full-fledged interaction within the Internet of Things ecosystem.

Transfer of multimedia via DLNA and Cast protocol

DLNA and Google Cast are the best ways to play back video files stored in your phone’s memory or stream from browsers. Unlike full screen duplication, here the TV decodes the video file itself, receiving only a link to the stream, which significantly reduces the load on the smartphone and saves battery power.

Many video players, such as VLC for Android or MX Player, have a built-in broadcast button. Open the video file on your phone, click the icon "Cast" (rectangle with waves) and select your Xiaomi TV. The video will play on the big screen, and the smartphone can be used for other tasks or even blocked.

So it works with photo and music. In the standard MIUI gallery, you can also have a live stream button when you watch an album, and you can create slideshows from your vacation photos right on your TV, controlling the slides from your phone, and it creates a cozy atmosphere without having to drop files onto a flash drive.

Wired connection via USB and HDMI

In situations where the wireless network is overloaded or requires maximum signal stability, it is advisable to use a wired connection. However, there is an important caveat: most Xiaomi TVs are not able to receive video signals through normal video. USB-It's a port, because it's only designed to read files from flash drives. HDMI.

If your smartphone supports video output (MHL, Slimport, or USB Type-C output with DisplayPort Alt Mode), you can use a special adapter. Connect one end to the phone and the other to the HDMI cable that is inserted into the TV, and then select the appropriate port in the signal sources (Input).

This method ensures no delays (input lag), which is critical for cloud gaming or displaying dynamic content, and the wired connection is independent of interference in the air and works even in the absence of Internet, if the content is already loaded into the device’s memory.

⚠️ Note: Not all Xiaomi smartphones support image output via USB-C. Budget models often lack this feature and the adapter won't work.Check your CPU specification before buying the cable.

💡

Use HDMI cables no longer than 3 meters long to maintain 4K signal quality. Long cables without active amplification can cause flickering or color loss.

Solving problems and eliminating synchronization errors

Even when configured correctly, there can be situations where devices can’t see each other or the connection is constantly broken, most often the problem lies in the settings of the router firewall or antivirus, which blocks local data exchange. Try temporarily disabling protection or adding devices to the exception list.

Another common reason is outdated software. Check for firmware updates for your TV in Settings → About TV → System Update. Similar steps need to be taken for your smartphone, as protocol compatibility often improves in newer versions of Android.

If nothing works, reset the network settings on both devices, which won't delete your personal files, but will return the Wi-Fi and Bluetooth settings to factory values. Once you reset the network, the problem usually disappears.

💡

90% of synchronization problems are solved by restarting the router and updating the TV firmware to the latest version.
