Xiaomi TV is a powerful multimedia center that easily turns a living room into a home theater. However, the diagonal of a smartphone is often not enough to watch movies with the whole family or present photos to guests. Fortunately, wireless image technology allows you to instantly display content from the screen of a mobile device to a large display without unnecessary wires.
Connection can vary depending on your smartphone operating system and your TV model. Android TV and PatchWall have many protocols, such as Chromecast built-in, Miracast and DLNA, and understanding the differences between them will help avoid delays and audio desynchronization.
In this article, we will take a look at all available broadcast methods, from standard system functions to the use of specialized applications, you will learn how to configure the network for maximum speed and what nuances should be considered when working with different video file formats.
The main methods of wireless image transmission
Before you start setting up, it's important to understand that there are several broadcast technologies, each with its own features: Miracast creates a direct Wi-Fi Direct connection between devices, allowing you to transmit images even without Internet access, which is ideal for a quick display screen.
Google Cast technology works differently: the phone only transmits a link to the content and control commands to the TV, and the stream itself is downloaded by the TV directly from the network, which frees the smartphone and ensures high quality images without jerks, if the Internet channel is stable.
Apple owners are familiar with the AirPlay 2 protocol, which is natively supported by new Xiaomi models, which provides minimal latency and high quality audio and video transmission, and the choice of method depends on your goals: a full copy of the screen or only streaming video.
- 📡 Miracast – real-time screen duplication, suitable for games and presentations.
- 🌐 Google Cast – streaming content from apps (YouTube, Netflix), the phone is used as a remote.
- 🍏 AirPlay – Apple’s standard for streaming from iPhone and iPad to compatible TV.
- 📂 DLNA — Playing local files from your phone through a media server.
⚠️ Note: Both devices must be connected to the same Wi-Fi network to work with Google Cast and AirPlay. If the router distributes 2.4 GHz and 5 GHz networks with different names, make sure that the phone and TV are in the same range.
Equipment preparation and network setup
Connection stability is directly dependent on wireless network quality. It is recommended to use a router that supports 802.11ac (Wi-Fi 5) or later. 5 GHz frequency provides much higher bandwidth, which is critical for video transfer to 4K.
Make sure your TV software is up to date. Go to the settings section of the Xiaomi TV menu and check for system updates. Older versions of the firmware may have bugs in Wi-Fi modules or data protocols.
☑️ Checking before connection
If you plan to broadcast heavy files over a local network, make sure that the router signal is confidently received at the installation site of the TV.
How to improve Wi-Fi signal for TV?
Broadcasting through the built-in Chromecast
The easiest way to run a video is to use the Google Cast feature built into most popular apps: Open YouTube, Netflix, Twitch, or another supported service on your smartphone. In the player, find the characteristic rectangle icon with waves in the corner.
After clicking on the icon, the system will prompt you to select a device, which should appear in the list your Xiaomi Mi TV or model name, for example, MI TV 4A. The first connection may require confirmation of the code that will appear on the TV screen.
The advantage of this method is that once you start playing, you can fold the app or even lock the phone, and the video will continue to go on the big screen, which saves battery life and allows you to use the smartphone for other tasks.
| Parameter | Description | Recommendation |
|---|---|---|
| Protocol | Google Cast | Used for streaming services |
| Quality. | Up to 4K HDR | Depends on the speed of the Internet |
| Impact on the phone | Minimum | Other applications can be used |
| Stability | Tall. | Requires stable Wi-Fi |
💡
Google Cast is the most energy-efficient way to view videos, as the TV processor, not the smartphone, decodes the stream.
Screen duplication via Miracast
If you want to show content in an app that doesn't support Cast, or demonstrate how your browser works, use the screen duplication feature. On Xiaomi TVs, this feature is often called Wireless Display or Translation, and you need to activate it in the signal source list or in the app menu.
On an Android smartphone, go to the notification curtain and find Translation, Smart View (Samsung), or Projection. After searching for available devices, select your TV. The image from your phone will appear on the TV screen with minimal latency.
It should be noted that when the phone is duplicated, the display does not turn off, which can lead to faster battery discharge, and the aspect ratio may differ: if the phone is vertical, black stripes will appear on the side of the side.
- 📱 Open the Quick Access settings on Android.
- 📡 Select “Translation” or a similar menu item.
- 📺 Wait for the name of your Xiaomi to appear TV.
- 🔗 Click to connect and confirm the request on TV.
⚠️ Note: When you duplicate the screen, the notifications that arrive on the phone (messages, calls) will be displayed on the TV. It is recommended to turn on the "Do Not Disturb" mode before starting to watch.
Use of Mi Remote and Mi Home
To integrate more deeply with the Xiaomi ecosystem, you can use the official Mi Remote or Mi Home app, which allows you not only to control your TV, but also in some cases initiate the transfer of media files, especially for users who have a smartphone is also a Xiaomi product.
In the Mi Home app, add your TV if you haven't already. The device management interface often has a Translation button or the option to select files to play, which is convenient for showing photos from a gallery or video stored in the phone's memory.
The functionality may vary depending on the regional version of the app and the TV model. In the global version, the interface may be called Xiaomi Home, and in the Chinese version, Mi Jia. Make sure that accounts are synchronized.
The Secret Features of Mi Remote
Broadcast from iPhone and iPad (AirPlay)
Owners of Apple devices can use the built-in AirPlay feature. Modern Xiaomi TVs based on Android TV 9.0 and higher, as well as models with a PatchWall shell, have built-in support for AirPlay 2. No additional applications need to install.
Open Control Point on your iPhone (swipe down from the top right corner or bottom up on older models). Click on Screen Replay icon (two rectangles). Select your Xiaomi TV from the list.
The image will be instantly displayed. AirPlay provides excellent synchronization of audio and video, making this method preferred for watching movies from iTunes or photo albums.
💡
If you connect through AirPlay, the sound is coming through your phone instead of your TV, open the Control Point on your iPhone, click on the AirPlay icon in the music playback unit, and select the Xiaomi TV as the output device.
Resolving and eliminating delays
Even if you set it up properly, you can have problems, like desynchronizing the sound, low resolution, or disconnecting the connection. Often it's because of congestion in your Wi-Fi channel. Try switching your router to a less loaded frequency or channel.
If video slows down when you duplicate your screen, close the background apps on your phone that may be consuming traffic or CPU resources. Also make sure that the TV doesn't run heavy games or upgrade processes in the background.
In some cases, resetting your network settings helps. On your TV, go to Settings → Network and Internet, select your network and click "Forget." Then reconnect by entering your password.

⚠️ Attention: Use VPN On a smartphone, it is often impossible to search for a TV on a local network, because VPN It changes the network segment of the device. VPN.
💡
The most common cause of broadcast problems is different Wi-Fi range (2.4 GHz vs. 5 GHz) or the enabled client isolation mode on the router, which prevents devices from seeing each other.
