Modern Xiaomi smartphones have powerful screens, but for watching movies with the whole family or showing photos to guests, the diagonal of the mobile device is often not enough. Fortunately, wireless signaling technology makes it easy to zoom a picture onto a big TV screen without any extra wires, which is especially convenient when you don't have any hands on. HDMI-cables or simply don’t want to get confused.
The connection process depends on the type of TV you have, whether it supports a Smart TV or a regular panel, and in both cases, Wi-Fi is the main bridge for data transmission, and it's important to understand that the quality of the broadcast depends on the speed of the router and the stability of the signal in the room.
In this article, we will discuss all the current ways of transmitting images, built-in features of the MIUI shell and third-party utilities. You will learn how to avoid delays and desynchronization of sound, and what to do if the TV does not see the phone. Both devices must be connected to the same Wi-Fi network (the same SSID), otherwise detection will be impossible.
Built-in Translation function in MIUI
The easiest and fastest way to do this without additional software is to use the Translation system function, which is based on the Miracast protocol, which is supported by most modern Smart TVs (Samsung, LG, Sony, Philips) and Android TVs.
You don't have to look for hidden menus to start the process, just lower the notification curtain down and find an icon called Translation or Cast. If the icon isn't available quickly, click on the edit pencil and drag it to the active screen.
Once activated, the phone will start searching for available devices within range of the network, and a request for permission to connect may appear on the TV screen, which must be confirmed by the remote, sometimes this process takes up to 10-15 seconds.
⚠️ Note: Translation function in MIUI It may not work with Apple TVs. TV or devices that only support AirPlay, without installing additional intermediary applications.
If the search doesn't work, make sure your TV has Screen Mirroring enabled, which can be called Screen Share, Miracast or simply Wireless Monitor.
Using the Google Home app for Chromecast
Many modern TVs have a built-in Chromecast module. To work with it on the Android system installed on Xiaomi phones, the best way to use the official Google Home app is to not only duplicate the screen, but also manage media files.
Download the app from the Google Play Store and log in to your Google account.The program will automatically scan the network and find all compatible devices.Click on your TV icon to open the control panel.
In the bottom menu, select Cast my screen, and the system will alert other users to the sound and image from the phone on the network, and confirm the action by clicking Start.
- 📺 Perfect for Android TVs TV Google TV.
- 🎮 Allows you to broadcast the screen during the game, but there may be a delay in input.
- 🔊 Sound is transmitted simultaneously with video, without desynchronization.
The advantage of this method is the stability of the connection: the Chromecast protocol is less sensitive to interference than the standard Miracast, and provides a smoother picture when watching high-resolution video.
💡
If the broadcast is interrupted or the picture twitches, try restarting the router. Often the problem lies in the router's crowded cache, not in the phone.
Xiaomi Mi TV (Mi Remote) app
Owners of Xiaomi and Redmi appliances can use the Mi Remote ecosystem app (or Xiaomi TV), which is often pre-installed on the system, but may require an update via GetApps. This app turns the smartphone into a remote and media center.
After launching the application and adding a TV (automatically or manually) IP-Go to the tool section, where you will find the Translation function, or «DLNA». This method is especially good for viewing photos and videos from the gallery.
Unlike full screen mirroring, here you choose a specific file to play, and the TV will load the stream itself, unloading the phone's processor, saving battery life.
| Parameter | Mi Remote (DLNA) | Broadcast (Miracast) |
|---|---|---|
| Processor booting | Low. | Tall. |
| Battery charge | It's slow. | Quick discharge. |
| Phone interface | Free for other tasks | Busy with TV imagery |
| Support for formats | Depends on the TV codecs. | Full screen copy |
Using DLNA through a proprietary app is the best choice for long-term movie watching, and you can respond to messages or browse through social media while the movie is on TV.
Broadcasting through the browser and third-party services
If the built-in methods don’t work or the TV is old but has Smart TV support, you can use a browser. Open on your Chrome or MI Browser phone and go to a site with video content (YouTube, Vimeo, online cinemas).
The video player on the site often has a Cast button, and if you click on it, you'll send a link to the video directly to the TV, and the phone is just a remote control.
For more complex tasks, there are aggregator applications, such as TV Cast or AllCast, that can stream browser content or file formats that a standard TV player does not read.
⚠️ Note: Free versions of third-party broadcast apps often get ads. Be careful with the permissions you give to such programs.
Some services require you to install a special extension or receiver app on the TV itself (via the TV app store).
Why do some apps block the broadcast?
The solution to the problem: the TV can’t see the phone
Devices that are on the same network but not on each other are common, and the first thing you do is check if the router is running AP Isolation, which prevents devices on the Wi-Fi network from communicating with each other.
If the router is dual-band, make sure that both the phone and the TV are connected to the same frequency (either both at 2.4 GHz or both at 5 GHz).
Try to perform the following steps to reset the connection:
- 🔄 Reboot the router by turning it off for 30 seconds.
- 📡 Turn off and reconnect Wi-Fi on both devices.
- 🔥 Temporarily shut down mobile internet (4G/5G) on the phone so that the system does not try to use it to search.
If nothing works, check the date and time settings, and a time difference of even a few minutes can disrupt the security and detection protocols on the LAN.
☑️ Diagnostics of connection
Optimizing quality and eliminating delays
Playing or watching dynamic video can result in sound and image or lag desynchronization, often due to lack of channel bandwidth. For games, use Game Turbo mode on Xiaomi, which prioritizes the game's network traffic.
Make sure you use a Wi-Fi standard of 802.11n (Wi-Fi 4) or Wi-Fi 5 (ac) or Wi-Fi 6 (ax). Older standards may not pull Full HD stream without compression.
Close the background apps on your phone that are actively pumping traffic (torrents, background updates, cloud sync photos) and this will free up the channel for transmitting video streams to the TV.
In the developer settings (Settings → About Phone → 7 times click on the MIUI version → Advanced Settings → For developers), you can try to change the video encoder, but this requires caution and can lead to unstable system operation.
💡
5GHz Wi-Fi connection stability is much higher for video broadcast than 2.4GHz, but it has a shorter range. Get closer to the router for a better signal.
