Modern Xiaomi TVs, powered by Android TV or PatchWall, have evolved into powerful multimedia centers that can play content not only from embedded apps but also from external devices. The ability to display images from a smartphone to a large screen is one of the most popular features, allowing you to show photos, run video files or even play mobile games at full volume and in high detail. The process of streaming can seem difficult for beginners, but it is based on standard wireless protocols that are already integrated into most modern gadgets.
In this article, we will take a look at all the available methods for broadcasting from your phone on a Xiaomi TV using both built-in system tools and third-party software solutions. You will learn about the intricacies of Miracast and Google Chromecast protocols, and understand why wired connection may be preferable to wireless in some cases. Understanding these differences will help you avoid image delays and audio dissynchronization when watching movies or streaming.
Before you start setting up, make sure your devices support the necessary technology. Most Xiaomi, Redmi and POCO smartphones are equipped with Wi-Fi Direct modules, which makes them fully compatible with the brand’s TVs. We will look at scenarios for different versions of MIUI and HyperOS firmware, since the menu layout may vary slightly depending on the year of release of the device.
Wireless Image Transmission Technologies: How It Works
The fundamental principle for transmitting a picture from a smartphone to a TV screen is the use of Wi-Fi Direct, which allows devices to connect directly to each other without the need for a router, although in most use cases, the home Wi-Fi network is still used to coordinate data flows. The Xiaomi ecosystem supports several standards, among which Miracast dominates, providing a mirror display of the entire screen of a mobile device.
Google Cast technology, which is built into Android TVs, is particularly noteworthy. Unlike simple mirroring, it allows content from specific apps like YouTube or Netflix to be streamed directly to the TV, freeing up the smartphone for other tasks. The quality of transmission is often higher, since the TV itself downloads video from the Internet, receiving only a command from the phone.
⚠️ Note: When using the Miracast protocol, the load on the smartphone battery increases significantly, since the processor and Wi-Fi module work in a strengthened mode. It is recommended to keep the charger on hand or connect the phone to the network during long sessions.
It is critical that both devices are on the same LAN for stable broadcasting. If your router supports dual-band, it is better to use 5 GHz, which provides higher bandwidth and less interference compared to the 2.4 GHz band. This is especially true when transmitting high-resolution 4K or high-bitrate Full HD video.
Preparing devices for synchronization
The first step before you start setting up is to check the software. Make sure your Xiaomi TV has the latest firmware installed. Go to Settings → About TV → System Update and check for new versions of the software. It’s also worth updating the system components on your smartphone, especially if you’re using the MIUI+ or Xiaomi Share ecosystem features.
The second important step is network setup. Both devices must be connected to the same Wi-Fi hotspot. If your router distributes networks with the same name (SSID) for different frequencies, there is usually no problem, but in rare cases, older TVs may not "see" new phones if they are on different subnets, in which case try temporarily disabling mobile Internet (4G/5G) on your smartphone so that the system is forced to use the Wi-Fi channel.
☑️ Checklist of preparation for connection
Some users are faced with the fact that the TV is not displayed in the list of available devices, often due to power saving settings or router firewall. AP" (AP Isolation, which prohibits devices within the network from sharing data with each other, is also worth checking whether a smartphone should not ban the use of the local network for system services.
💡
If the TV and phone are in different Wi-Fi bands (2.4 GHz and 5 GHz) and can’t see each other, try temporarily switching both devices to 2.4 GHz for initial pairing, after which you can return the settings back.
Broadcasting through the built-in Translation function in MIUI and HyperOS
Xiaomi smartphones have a convenient built-in image display tool that does not require additional applications. This method is based on the Miracast standard and provides full screen mirroring. To activate the function, open the control panel (curtain) and find the icon "Translation" or "Cast." If the icon is not, it can be hidden in the editing menu of quick settings or located on the Settings path → Connection and Sharing → Broadcast.
Once the function is enabled, the phone will start searching for available devices on the network. Your Xiaomi TV should appear in the list. When choosing a device on the TV screen, you may receive a request for confirmation of connection, which must be accepted by the remote control. After successful pairing, the image from the smartphone will appear on the large screen. that in this mode the phone can be locked, and control is only through the touch screen.
For users looking for more advanced features, Xiaomi offers a feature called “My Screen” or Xiaomi Share (depending on the region and firmware version). It allows you not only to broadcast the image, but also to control the phone from the remote, drag and drop files and launch applications. Activation occurs through the Settings menu → Connect and share → My screen, where you need to turn on the request.
| Parameter | Miracast (Translation) | Google Cast | HDMI wired |
|---|---|---|---|
| Type of connection | Wireless (Wi-Fi Direct) | Wireless (via router) | USB-C cable to HDMI |
| Delay (Latency) | Medium/High | Low (for video) | Absent. |
| Image quality | Depends on the signal. | Up to 4K HDR | Native 4K/8K |
| Battery consumption | High-pitched | Low/Mediocre | Charging the phone |
Using the Google Home app for Chromecast
If your Xiaomi TV is powered by Android TV, it supports Google Chromecast built-in technology. It's a more modern and stable way to broadcast, especially for video content. To manage this process, the Google Home app, which is Google's smart home control center, must be installed on your smartphone. Make sure the app has all the necessary permissions, including access to geolocation and local network.
When you start Google Home, find your TV on your device list, and if you click on the icon, you'll see the "Cast my screen" button, which, unlike Miracast, is more like a remote control, and the video is decoding by the TV, which allows for smoother playback and less workload on your smartphone, ideal for watching movies from your browser or streaming services.
⚠️ Attention: It is critical for Google Cast to have the same Google account enabled in the Google Home app and on the TV itself, or devices must have open detection settings. If the TV is not located, check the privacy settings in the app.
The advantage of this method is that you can stream tabs on Google Chrome, you can open any web page on your phone, click on the Share menu or three dots in your browser and select Translate, which allows you to display content that does not have native support in your TV applications, including DRM-protected content from some websites.
Why can the broadcast be interrupted?
Third-party applications for enhanced capabilities
In some cases, embedded tools are not enough, such as if you want to stream content from applications that block screen recording, or if you want to transfer audio from a computer to a TV. For such tasks, there are specialized applications such as Web Video Caster, AirScreen or LocalCast. These are installed on both the phone and (in some cases) on the TV via the Google Play Store.
The AirPlay & Cast Receiver app (or analogues) lets you turn a Xiaomi TV into an Apple device receiver (AirPlay) or add DLNA support for older smartphones. Once installed on your TV and phone, you can stream videos, photos and music in a variety of formats that the native system may not support. This is especially useful for iPhone owners who want to connect their gadget to an Android TV.
For advanced users who want to stream audio from a PC or specific audio streams, SoundWire or AirAudio is a great application. They allow you to use the TV as a wireless speaker system. Installing the server part on the computer and the client part on the phone (or vice versa, depending on the direction of the flow) opens up new possibilities for creating a home audio system.
Wired connection: maximum quality without delay
If wireless isn’t as good as you want, or if you’re planning to play games where every millisecond matters, you should consider wired connectivity. You’ll need a USB-C to HDMI adapter to do that. It’s important to understand that not all Xiaomi smartphones support video output via a USB-C port. This feature (DisplayPort Alt Mode) typically has flagship Mi and Xiaomi models, while budget Redmi and POCO are often devoid of that capability.
The connection process is very simple: insert an adapter into the phone's charging socket, and it has an HDMI cable going to the TV. The TV automatically detects a new signal source. You only have to select the appropriate input (for example, HDMI 1 or HDMI 2) in the source menu on the remote. The image will appear instantly, without delays and compression artifacts.
💡
Wired connectivity via the USB-C to HDMI adapter is the only way to get a 4K@60Hz picture without compression and delays, but it requires support for DisplayPort Alt Mode technology from the smartphone.
It’s worth noting that when wired, the phone usually doesn’t go into full mirroring with control, but simply duplicates the screen. However, if your phone supports Desktop Mode (similar to Samsung DeX, but in Xiaomi implementation this is less common and depends on the version of MIUI), you can get a full desktop on the TV screen.
Solving common problems and errors
One of the common problems is when the phone sees the TV, but the connection is reset after a few seconds. This often indicates codec incompatibility or too high a resolution of the source. Try to lower the screen resolution on the phone in the Screen settings → Resolution to 1080p before broadcasting. Also helps rebooting the Wi-Fi module on both devices.
If there is no audio when streaming a video, check the audio settings in a particular app or Android system. Sometimes the default system continues to output audio through the phone speaker even when the video is going to the TV. In this case, the notification panel when the broadcast is running should have a audio output switch that you need to translate to a Chromecast or TV device.
⚠️ Attention: When in use VPN smartphone-based broadcast (Miracast/Chromecast) It often stops working because VPN It encrypts all traffic and hides devices from each other. VPN-linkage.
In cases where nothing works, you may need to reset your network settings on your TV. Go to Settings → Devices → Network → Network Reset. This action will delete all stored Wi-Fi passwords and Bluetooth settings, but often solves the “invisibility” problems of devices on the LAN caused by software failures of the router or the TV itself.
