Xiaomi’s modern Android TVs have evolved into powerful multimedia centers capable of displaying content not only from embedded apps but also from external devices. Broadcasting a smartphone screen to a large display is one of the most sought-after features, allowing you to share photos, watch movies or show presentations in high quality. Owners of Xiaomi and Redmi devices often look for ways to sync their gadgets to enjoy content without the limitations of a small screen.
There are several proven methods to stream from phone to TV, each with its own features and connectivity requirements. Miracast, Google Cast and DLNA offer different use cases, from full screen cloning to link-streaming, and understanding the differences between these protocols will help you choose the most appropriate option for your particular situation and TV model.
In this article, we will take a look at all the available connectivity options, from built-in MIUI features to specialized applications. Wi-Fi is the most convenient but requires network configuration. We will also address issues such as image delays or the lack of a device on the list available for connection.
Network requirements and equipment preparation
Before you start setting up your broadcast, you need to make sure your hardware meets the basic requirements for stable multimedia protocols. The key to most wireless methods is to have your smartphone and TV on the same LAN, which means that both devices must be connected to the same Wi-Fi router. If your phone uses 4G/5G mobile internet and your TV is connected to your home network, direct detection of the devices will not be possible.
The quality of the image transmitted depends on the speed and stability of the wireless connection. To transmit high-resolution video, such as 1080p or 4K, it is recommended to use a 5 GHz network, which provides higher bandwidth compared to the 2.4 GHz bandwidth. If the router supports dual-band mode, make sure that both devices are connected to the same frequency, although modern routers often combine networks under the same name.
⚠️ Note: If your router uses Client Isolation or a restricted guest network, devices may not see each other.
It’s also worth checking the software versions on both devices. Xiaomi TVs with PatchWall shell or pure Android TV may have different menu names, but the way things work remains the same. Make sure the TV has a wireless display feature or connectivity readiness enabled, as some models don’t activate this mode by default to save resources.
☑️ Checking before connection
Use of the built-in Translation function in MIUI
Xiaomi smartphones running MIUI or HyperOS have a built-in tool for wirelessly connecting to external displays, which is based on the Miracast protocol, which allows you to broadcast the screen in real time without having to install additional software. To activate it, open the curtain control center and find the icon "Translation" or "Cast." If the icon is not available, it can be added through the shortcut editing menu or found in the settings through search.
Once the feature is enabled, the phone will start scanning available devices within network range. On the Xiaomi TV screen, a request for confirmation of connection may appear, which must be received by the remote control. In some cases, you need to pre-start the Wireless Monitor or Wireless Display application on the TV itself to become searchable. The pairing process usually takes no more than 10-15 seconds with a stable signal.
The feature of the native MIUI broadcast is the ability to choose the mode of operation: you can duplicate the screen completely or display the image only in certain applications that support extended output. This allows you to use the phone for other tasks while the TV is video. However, it is worth considering that when the screen is completely duplicated, the battery consumption of the smartphone increases significantly, and the device can heat up.

To reduce latency when broadcasting games, close the background apps on your smartphone and come closer to the router to ensure the maximum Wi-Fi signal level.
Broadcasting via Google Home and Chromecast
Xiaomi TVs are often Android TV certified or have built-in support for Google Cast (Chromecast built-in) technology, which opens up access to a more advanced streaming method that is managed through the Google ecosystem. To implement this method, you will need a Google Home app installed on your smartphone, which will automatically detect the TV if it is linked to your Google account and is on the same network.
Unlike Miracast, Chromecast technology works on a “control panel” principle: you send a command to the TV, and it independently downloads content from the Internet without loading the phone’s processor. This is especially convenient for streaming services such as YouTube, Netflix or Kinopoisk. Within the applications of these services, you just click on the broadcast ikon (a rectangle with waves) and select your Xiaomi TV from the list.
If you want to stream your phone screen (like a browser or game) through Google protocols, Google Home will need to select your TV and click on the Translate screen button, which is often better in quality and less latency than standard Miracast, thanks to Google’s optimization of codecs, but requires Google Play services on your smartphone to work.
| Characteristics | Miracast (Translation) | Google Cast (Chromecast) | DLNA |
|---|---|---|---|
| Type of transmission | Screen duplication | Streaming/Duplicate | Media files only |
| Dependence on the phone | High (screen should be on) | Low (for streaming) | Medium |
| Quality. | Depends on the Wi-Fi signal. | Adaptive, often higher | Original File Quality |
| Sound. | It's broadcast with the video. | It's broadcast with the video. | Audio/video files only |
Application of third-party applications and DLNA
When built-in techniques don’t work or functionality isn’t enough, third-party apps come to the rescue. One of Xiaomi’s most popular TV solutions is AirScreen or AirPin, which can be found in the Google Play Store on the TV itself. These apps emulate AirPlay protocols (for iPhone owners) and improve compatibility with Android devices, providing more flexible buffering and quality settings.
To transfer local files, such as photos or saved video files, DLNA technology is often used. It does not require screen duplication. You just install a media player application with DLNA support on your phone, such as VLC for Android or BubbleUPnP. The player menu selects the option “Rendering” or “Cast”, after which the phone finds the TV and starts transferring the file directly using the TV as a decoder.
Another powerful tool is the Web Video Caster app, which allows you to stream videos from sites that don't have official Chromecast support. You open a site in the app's built-in browser, select a video, and the link is sent to a Xiaomi TV for playback, which bypasses the limitations of mobile browsers and allows you to display content to the big screen even from unpopular resources.
⚠️ Warning: When installing third-party apps on your TV, be sure to check the permissions. Some free versions of programs may contain intrusive ads that will cover the entire screen while watching.
Wired connection via HDMI and USB-C
While wireless technologies are convenient, they don’t always guarantee stability, especially in noisy ether environments. Wired connection via USB-C to HDMI adapter provides maximum image quality without delay and compression. To implement this method, your Xiaomi smartphone must support video output via a charging port (MHL or DisplayPort Alt Mode technology). Flagship models usually have this support, while budget segments can be limited only to data transfer.
You'll need a special adapter or docking station to connect, one end connects to the phone's charging socket, and the other end connects to the TV with an HDMI cable, and then you switch the TV's signal source to HDMI 1 or HDMI 2 mode, which corresponds to the port you're using, and the image on the TV screen will appear automatically, often in horizontal orientation.
The advantage of the wired method is that it can charge the device during use if the adapter has an additional power port, and it is ideal for games where every millisecond of response is important, since it excludes any network lags. However, it is worth remembering that the cable limits mobility and requires the phone to be in close proximity to the TV.
Why can't my phone see the HDMI adapter?
Solving Connection Problems and Errors
Despite the ease of setting up, users may encounter a number of difficulties: the most common problem is that the TV does not appear in the list of available devices, first of all, check whether the antivirus or firewall on the router blocks local device detection. Also try rebooting the Wi-Fi module on both gadgets: turn it off and turn it on again. Sometimes it helps to simply restart the router, which clears the cache. DHCP-server.
Another common scenario is audio-image desynchronization or picture jerking, which is a clear sign of a lack of channel bandwidth or overheating of the phone's processor. Try to reduce the quality of the video you're streaming in the source app settings or bring the phone closer to the router. If you're using the 2.4 GHz band, switching to 5 GHz can dramatically improve things, because that range is less crowded by neighborhood networks.
In rare cases, the problem lies in the outdated firmware of the TV. manufacturers regularly release updates that correct errors in communication protocols. Go to the TV menu Settings → About TV → Update and check for a new version of the software. Installing current firmware often solves compatibility problems with new versions of Android on smartphones.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the absence of interference in the air, so the router must be in the line of sight of the devices.
