Xiaomi’s modern smart TVs make it possible to turn the living room into a real multimedia center, but many owners do not know how to properly display images from a smartphone or tablet. The screen broadcast process (or Screen Mirroring) opens up access to a huge amount of content, from watching high-resolution movies to showing presentations and games on a large diagonal. Unlike older models, the new Xiaomi Mi TV and Redmi Smart TV support many data transfer protocols, which makes the procedure flexible but sometimes confusing for the untrained user.
The main challenge is the variety of operating systems found on Chinese TVs, some running Android TVs, others running PatchWall or even Linux, which requires customization. Understanding which protocol your device uses is key to successful synchronization without delay and audio desynchronization. In this article, we will look at all the available methods, from built-in system functions to wired connection.
Before you start setting up, you need to make sure that all devices are on the same LAN. This is a fundamental requirement for wireless video streaming technologies. If your router is sending out a signal at 2.4 GHz and 5 GHz, it is advisable to connect both the phone and the TV to the same frequency to avoid problems with the visibility of the devices in the list of available receivers.
Preparation of equipment and network for stable broadcasting
The first step in the setup process is to organize your network environment correctly. Wireless connectivity is critically dependent on signal quality and no interference. If you plan to stream video in 4K or play dynamic games, using a Wi-Fi router that supports Wi-Fi 5 (ac) or Wi-Fi 6 (ax) will be a significant advantage.
Go to your Xiaomi Mi TV settings and check your current connection. Use the remote control and go to the Settings → Network and Internet menu. Make sure the connection status is displayed as "Connected" and the signal speed is sufficient. A weak signal can lead to image artifacts and interruption of the stream.
⚠️ Note: If your router is set to automatically switch customers between the 2.4GHz and 5GHz bands (Smart Connect feature), try temporarily disabling it and force both devices to connect to a 5GHz network. This often solves the problem when the phone doesn’t see the TV on the list of available devices.
It’s also worth checking the TV’s software version. Manufacturers regularly release updates to improve the stability of Wi-Fi Direct and Miracast. A firmware update can fix hidden bugs that interfere with the wireless display function.
Using the built-in Chromecast feature on Android TV
Most modern Xiaomi TVs running Android TV or Google TV have built-in support for Chromecast built-in technology. This is the most convenient and stable way to transfer content, since it is integrated directly into the Google ecosystem. You do not need to install additional apps on the TV, just having a standard set of services.
To get started, open the app on your smartphone that you want to display content from. This can be YouTube, Netflix, VK Video, or any other service that supports the casting protocol. Find the broadcast icon (rectangle with waves in the corner) and click on it. In the list that appears, select the name of your Xiaomi Mi TV.
It is important to distinguish between two modes of operation: broadcasting a browser tab or a specific video and full mirror display (Screen Mirroring). In the first case, the phone acts only as a remote control, and the video is downloaded by the TV directly from the Internet, saving battery power of the smartphone. In the second case, the image is encoded in real time by the phone and transmitted to TV, which requires a more powerful processor and a stable communication channel.
💡
To fully mirror the Android smartphone screen, use the Translation feature in the notification curtain or through the Google Home app by selecting the Translate screen option.
If automatic connectivity does not occur, check the permissions in the Google Home app. Make sure the app has access to the local network and microphone (required for initial setup of some devices). Also make sure that the TV in Settings → Apps → Google Cast is not subject to restrictions on connecting new devices.
Streaming from iPhone and iPad via AirPlay
Apple device owners may be faced with the question of how to broadcast the screen to Xiaomi TV, given the closed iOS ecosystem. Fortunately, modern models of Xiaomi Mi TV support the AirPlay 2 protocol or emulate it, which allows you to display the image from an iPhone or iPad without having to buy an additional Apple TV console.
The process of running a stream, known as Screen Mirroring, is as simple as possible in iOS. Open the Control Point on your smartphone (swipe down from the top right corner on Face ID models or swipe up on models with a button).
- 📱 Make sure your TV has AirPlay support enabled in settings: Settings → AirPlay.
- 🔒 When you first connect on the TV screen may appear code that you need to enter on the iPhone to confirm the pairing.
- 🎧 The sound will also be transmitted to the TV, but it can be redirected back to the phone or AirPods via the audio output menu at Control Point.
In some cases, especially on PatchWall TVs, AirPlay support may not be available or may not work well, and in this situation, it is recommended to install a mediator app on the TV, such as AirScreen or Receiver for AirPlay, available from the Google Play Store on the TV itself.
⚠️ Warning: AirPlay is sensitive to network delays. If you see audio and video desynchronization, try lowering the quality of the broadcast content or bringing the router closer to the TV.

Application of third-party mirroring applications
When the built-in tools fail or the TV model is older, third-party apps come to the rescue. The market offers many solutions that implement their own video streaming protocols, often more flexible than standard Miracast or DLNA. One of the most popular and functional solutions is the Mi Remote application or specialized utilities like Web Video Caster.
The principle of operation of such programs is to install the client part on both the smartphone and the TV (or use the built-in TV browser). QR-code IP-This creates a direct link to the address, and it allows you to broadcast not only video files, but also the content of browsers, documents and even game screens with minimal latency.
Let’s take a look at the popular software options for enhancing the capabilities:
- 📺 Web Video Caster: Perfect for streaming videos from browsers, supporting many codecs and subtitles.
- 🖥️ TeamViewer QuickSupport: Allows you not only to see the screen, but also to control the TV (if the model supports), useful for demonstrations.
- 🎮 ApowerMirror: A powerful tool for gamers that offers low latency and high image quality, but often requires a paid subscription for full functionality.
When using third-party software, it is important to pay attention to the load on the smartphone processor. Real-time video coding is a resource-intensive task that can heat the device and quickly discharge the battery. It is recommended to keep the smartphone connected to the charger during long browsing sessions.
Wired connection via HDMI and adapters
For users who are critical to maximum reliability and no delays (such as connecting game consoles or holding professional presentations), wireless methods may not be effective enough. In such cases, wired connection through the HDMI interface remains the only solution.
Since modern smartphones rarely have a full HDMI port, you will need a special adapter. For devices with a USB Type-C port, you need an adapter that supports the USB-C to HDMI standard with the DisplayPort Alt Mode protocol. For older devices with Micro-USB, MHL or Slimport adapters are used, but their compatibility with specific Xiaomi phone models must be checked separately.
☑️ Checking before buying an adapter
The connection process is simple: insert the adapter into the smartphone charging connector, connect the HDMI cable to the adapter and to the free port on the TV. Then use the remote to select the appropriate signal source (for example, HDMI 1 or HDMI 2).
| Type of connection | Delay (Latency) | Image quality | Dependence on Wi-Fi |
|---|---|---|---|
| Chromecast (Online) | Low. | High (up to 4K) | Tall. |
| Miracast (Screen) | Medium | Depends on the signal. | Critical |
| HDMI Cable | Minimum | Maximum. | No. |
| DLNA (Files) | Low. | High. | Medium |
💡
Wired connection through HDMI-The adapter is the only way to ensure that there is no delay and interference, making it indispensable for gamers and professional presentations.
Solution: Why there is no image or sound
Even with the right setup, users can encounter technical problems. One of the most common situations is the presence of an image but no audio. Often the reason is that the source application has not switched the audio output to an external device. Check the audio settings inside the application (for example, YouTube or VLC) and choose Xiaomi Mi TV as the output device.
Another common problem is black bars at the edges of the screen or the wrong aspect ratio, which is solved through the settings of the image on the TV. Press the menu button on the remote, go to Settings → Image → Screen format and select "Size screen" or "16:9" to remove the edge trimming.
If the broadcast is constantly interrupted or the image is "sprinkled" on pixels:
- 📶 Check the Wi-Fi channel loading with other devices (torrents, downloads).
- 🔄 Restart router and TV (complete shutdown for 10 seconds).
- 📱 Turn it off. VPN on a smartphone, as it can block local device detection.
⚠️ Attention: Use VPN On a smartphone, it often makes it impossible to find a TV on the local network, as the virtual address of the device changes. VPN-service.
