How to connect the broadcast from your phone to the TV Xiaomi Mi: the complete guide

Xiaomi’s modern Smart TVs offer users a huge opportunity to consume content in multimedia, but there is often a need to bring to the big screen exactly what is in your smartphone. This can be a presentation, a family video, vacation photos or even a mobile app screen that has no analogue for a TV. Fortunately, the Mi Home ecosystem and the Android TV operating system (or PatchWall) provide several built-in and third-party ways to solve this problem without buying additional cables.

The process of synchronizing devices is based on wireless data protocols such as Miracast and Google Cast, which are supported by most modern gadgets. You do not need to be an expert in networking technologies to establish a connection, but understanding the basic principles of operation will help avoid typical connection errors. In this guide, we will discuss in detail all available methods, from standard system functions to specialized applications.

Before we get to specific instructions, it’s worth noting that broadcast quality is directly dependent on the stability of your Wi-Fi connection. Intermittent signal or low Internet speed can lead to image delays, sound desynchronization and artifacts on the screen. So for the best experience, make sure that both devices are in the zone of confident reception of the router signal.

Device Preparation and Network Requirements

A fundamental condition for successful broadcasting is that both smartphones and TVs are on the same local network, which means that both devices must be connected to the same Wi-Fi router. If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, it is desirable that both devices be connected to the same frequency, although modern routers often know how to correctly route traffic between bands within the same network.

The second important aspect is the software: make sure your Xiaomi Mi TV has the latest firmware installed, manufacturers regularly release updates that fix communication protocol bugs and improve compatibility with new versions of Android and iOS, and you can check through the TV settings menu by finding the "About System" or "Software Update".

Also, make sure that the smartphone has the necessary permissions enabled, and when the broadcast function is first launched, the system can request access to the local network or Bluetooth to detect devices, and denying these rights will make it impossible to search for the TV in the list of available gadgets.

⚠️ Note: If your router is set up in Guest Network mode, devices may be isolated from each other, and in this mode, the broadcast from phone to TV will not work, even if they are connected to the same Wi-Fi.

For stable 4K content, it is recommended to use a 5GHz network, as it provides the higher bandwidth required to transmit a high-resolution video stream without compression.

Use of the built-in Miracast (Wireless Display) function

Miracast technology is the standard for wireless image and sound transmission. On Xiaomi devices, this feature is often called “Wireless Display” or “Wireless Display” and allows you to completely duplicate the screen of your smartphone on your TV, which is ideal for demonstrating the interface of applications, games or browsers.

To start the process on the Xiaomi TV remote, find a button with a smartphone image or go to the signal source menu (Input) and select "Wireless Display." The screen will show the connection waiting interface with the name of your TV. Now we move to the smartphone settings.

On Xiaomi phones (MIUI shell or HyperOS), open the notification curtain and find the "Cast" option. In other Android models, the path may look like Settings → Connected Devices → Broadcast. Once you activate the search, the phone will start scanning the network for compatible receivers.

• 📱 Click on the name of your Xiaomi TV appearing.
• 📺 On the TV screen, a request for confirmation of the connection may appear, which must be accepted by the remote control.
• 🔄 Image from the phone will instantly appear on the big screen.
• 🔇 To stop broadcasting, press the Stop button on your phone or switch the signal source to TV.

It’s important to understand that when using Miracast, the smartphone screen remains active, and all notifications coming to the phone will be visible on the TV.

Broadcasting via Google Chromecast built-in

Unlike full screen duplication, Google Cast (Chromecast) technology allows you to stream specific content from apps directly to the TV, freeing up your smartphone for other tasks. Most Xiaomi Mi TVs have built-in support for this technology, making the process as easy as possible for the user.

The way it works is that you don't just throw a picture from your phone, you give the TV a command to play the video from the server, which means that the image quality will be the highest supported by the application, and the phone battery will be spent much more economically.

To use this method, open the app you want to see on TV (e.g. YouTube, Netflix, VK Video) and find the broadcast icon in the app interface, a rectangle with waves in the corner, usually located at the top or bottom of the player screen.

Once you click on the icon, select your Xiaomi TV from the list. The video will play on the TV, and the phone can be used as a remote control: pause, rewind or change the volume. Moreover, you can turn off the application or even turn off the smartphone screen - the playback on the TV will not interrupt.

Broadcasting content from applications (YouTube, Netflix, browsers)

Special attention should be paid to the stream from web browsers and specific applications. If you watch video through the Google Chrome browser on Android, you can stream a tab or the entire screen through the browser menu. To do this, click on three dots in the corner of the browser and select "Translate..." (Cast).

In the menu that opens, you can select a source: Translate tab will only transfer the contents of the browser, and Screen cast will duplicate the entire interface of the smartphone, working similarly to Miracast. This is a universal way for sites that do not have a native Cast button in their player.

iPhone (iOS) users may find that some apps don’t see Android TV directly, and in such cases, it’s recommended to use intermediary apps like Web Video Caster or the official Google Home app, which allows you to stream your iPhone screen to Chromecast-enabled devices.

⚠️ Note: When broadcasting protected content (DRM) Through a browser, for example, paid movies from some services, the image on the TV can be black, although the sound will go.

The new Xiaomi TV models support the AirPlay 2 protocol natively, in which case the iPhone control point (curtain) will appear button "Screen Replay", and your TV will be on the list of available devices on a par with Apple TV.

Use of third-party broadcasting applications

If built-in methods don’t work or the functionality isn’t enough, third-party solutions come to the rescue from the Google Play Store available on the TV, which often have more flexible codec and buffering settings.

One of the most popular solutions is the AirScreen app, which is installed directly on a Xiaomi TV and emulates AirPlay, Google Cast and Miracast receivers, which is especially useful for older TV or smartphone models that are not good friends with each other out of the box.

Another powerful app is LocalCast or BubbleUPnP. They let you stream not only online content, but also files stored in your phone’s memory or on a router-connected network storage (NAS), which is ideal for watching heavy 4K movies that don’t want to pull online services.

Installing third-party software requires a Google account on your TV. If you use the international version of Xiaomi TV, there will be no problems. In the Chinese version (CN Version), you may need to pre-install the Google Services Framework.

💡

If standard apps can’t see the TV, try temporarily disabling the VPN on your smartphone.Device Detection Protocols (DLNA/SSDP) are often blocked or not working correctly through VPN tunnels.

Solving problems and fixing connection errors

Despite the simplicity of the technology, users may encounter a number of common problems, the most common being "Device not found." If the search fails, the first thing you do is check if the router is running AP Isolation, which prevents devices from seeing each other.

Another common problem is the desynchronization of sound and image, which is often treated by rebooting both devices. 10-15 Seconds (full reset of residual current) and also restart your smartphone.

If the broadcast is constantly interrupted or the picture quality drops to "porridge of pixels", try to change the output resolution on the phone or reduce the flow quality in the application settings. It is also worth checking whether the Wi-Fi channel is congested with neighbor routers. In apartment buildings, the 2.4 GHz channel is often clogged, and switching to 5 GHz solves the problem.

⚠️ Note: When using cheap routers, simultaneous broadcasting 4K Video and active file downloads by other devices can put the network down.

In some cases, resetting network settings on a smartphone helps, which will remove stored Wi-Fi passwords and Bluetooth settings, but often eliminates software driver conflicts that interfere with stable media transfer.

💡

90% of connection problems are solved by checking that both devices are on the same subnet (the same number of devices). IP-router address, for example 192.168.1.X) and reboot the router.
