Xiaomi’s modern Android TVs have become powerful multimedia hubs, but their full potential is only revealed when synchronized with a smartphone. The ability to stream content from a mobile device to a large screen allows you to enjoy movies, photos and games in high quality without limiting the diagonal of the phone’s display. Owners of Xiaomi, Redmi and Poco devices often look for ways to quickly connect the gadget to the TV to arrange a home theater or show a presentation.
There are several proven methods of video transmission, each with its own advantages depending on the situation: You can use a wireless connection over Wi-Fi for convenience or choose a wired connection through a wired connection. HDMI-Understanding the differences between Miracast and Google Cast technology will help you choose the best option for your TV and smartphone model.
In this article, we’ll take a look at all the current ways to connect, from built-in MIUI features to third-party apps. We’ll look at the nuances of network setup, the requirements for the Android version, and how to solve common problems when a device can’t see the display. Whether you’re using an old set-top box or the latest Android TV panel, you’ll find a working solution here.
Preparation of equipment and network for synchronization
Before you start the broadcast process, you need to make sure that both devices are ready to communicate. A critical condition for wireless connectivity is to find your smartphone and TV on the same local Wi-Fi network. If your router supports dual-band operation, make sure that both gadgets are connected to the same frequency, preferably 5 GHz, to ensure high channel bandwidth.
Check the software’s relevance on both devices. On a Xiaomi TV, you can do this by going to Settings → About TV → System Update. On a smartphone, it usually looks like Settings → About Phone → MIUI Version. Outdated Wi-Fi drivers or display modules can cause unstable connection or complete lack of visibility of devices to each other.
⚠️ Note: If your router divides the network into guest and main, make sure that both devices are on the main network with access rights to local resources. DLNA Cast devices for security purposes.
For wired connectivity, you’ll need an adapter, as most modern Xiaomi smartphones don’t have a full video output via a standard charging connector without video support. You may need a USB-C to HDMI adapter with DisplayPort Alt Mode support. Not all phone models support cable output, so checking your device’s specification is a must.
☑️ Checking before connection
Use of the built-in Translation function in MIUI
The easiest and fastest way to bring Xiaomi’s phone screen to your TV is to use a regular feature of the system, often called “Translation” or “Wireless display,” which is based on the Miracast protocol, which allows you to transmit an image in real time without the need to install additional software.
To activate, lower the top menu curtain down and find the Translation icon. If it's not on the widget home screen, click on a pencil or edit button to add it to the active switches. Once turned on, the phone will automatically search for available displays on the network. On a Xiaomi TV with a PatchWall shell or a clean Android TV, you may need to confirm the connection, which will appear as a pop-up on the screen.
The quality of the image when using Miracast depends on the power of the Wi-Fi signal and the load of the air. The technology creates a direct connection between devices, which provides low latency, but can consume a significant battery charge of the smartphone. For viewing photos or videos from the gallery, this method is ideal, because it allows you to control content directly from the phone, using it as a remote.
Why can the broadcast be interrupted?
Importantly, when you broadcast the entire screen of your smartphone, the image on your TV will repeat the orientation of your phone. If you hold the device vertically, there will be black bars on the sides of the TV screen. For comfortable video viewing, it is recommended to turn the smartphone into horizontal mode to use the entire area of the TV matrix.
Google Cast Technology and Google Home App
Unlike Miracast, Google Cast (chromcast built-in) works on a different principle: instead of transmitting a video stream from a phone, a smartphone sends the TV only a link to content and control commands, and the TV downloads and plays the video itself, which frees up the phone's resources and allows it to be used for other tasks while watching.
The most convenient way to control your TV through Cast is to use the official Google Home app. Once installed and logged in, the app will display all available devices on the network. Select your Xiaomi TV from the list and click on Translate Screen. This method is especially effective for streaming services such as YouTube, Netflix or Kinopoisk, where picture quality is often higher than with direct mirroring.
| Characteristics | Miracast (Translation) | Google Cast |
|---|---|---|
| Principle of work | Screen mirroring | Linked streaming |
| Dependence on the phone | High (screen should be on) | Low (you can use other apps) |
| Image quality | Depends on the Wi-Fi signal. | Maximum (up to 4K HDR) |
| Battery consumption | High-pitched | Low. |
The advantage of Google Cast is that it supports high resolution and HDR format if the content and TV support it. However, to work with this method, the app from which you want to stream the video must have built-in Cast support. Otherwise, you will only be able to stream the Chrome browser tab or the entire screen through Google Home, which will return us to mirroring mode.
💡
To save battery power when using Google Cast, reduce the brightness of the smartphone screen to a minimum, as the image on the TV is formed regardless of the brightness of the phone.
Wired connection through HDMI-adapter
When wireless methods don’t provide the necessary stability or require maximum image quality without compression, wired connectivity comes to the rescue. For Xiaomi smartphones with a USB Type-C connector, there are special adapters that allow you to connect the HDMI cable directly, ideal for gamers or for presentations where every millisecond of response is important.
Not all Xiaomi phones support video output via USB-C. This feature, known as DisplayPort Alt Mode, usually has flagship Mi series models and some Xiaomi 13/14 models. Budget Redmi and Poco models often lack this capability at the hardware level.Be sure to check the specification of your processor and USB controller before buying an adapter.
The connection process is elemental: insert the adapter into the phone charging port, connect the HDMI cable from the adapter to the TV and switch the signal source to the TV in the appropriate mode (for example, HDMI 1). The image should appear automatically. If this does not happen, check the image output settings in the Settings → Connected devices → USB section, if there is a point that allows video output.
⚠️ Note: When connecting through HDMI The phone may start to run out quickly, as the adapter consumes energy. USB-port of the adapter, if such a possibility is provided by the design.
The use of cable ensures no delays (input lag), which is critical for dynamic games. In addition, the wired connection is not affected by interference from neighboring Wi-Fi networks or microwave ovens. However, mobility in this case is limited by the length of the cable, which is worth considering when planning the placement of equipment.
Third-party broadcast applications
If the standard tools of the system do not work or the functionality is not enough, applications from third-party developers come to the rescue. One of the most popular solutions is the application Cast to TV - XCast or Web Video Caster. These programs are able to find media files in the memory of the phone and send them to the TV using DLNA or AirPlay protocols (via emulation).
Cast-enabled browser applications like Puffin TV or dedicated video players like VLC for Android have a built-in broadcast button. In VLC, for example, you have to open a video, click on the Cast icon in the corner, and select your Xiaomi TV. This often works even when the system streaming fails, as apps use alternate native data paths.
There are also remote applications that not only broadcast the image, but also allow you to control the TV file system, which is useful if you need to open a file on your TV that lies deep in your smartphone folders without first copying it. However, it is worth remembering the safety of downloading such programs only from trusted sources, such as Google Play Market.
Some applications require you to install a server part on the TV itself. APK-Android file TV And the device is connected over a local network, and it's a good way to transfer heavy files that are inconvenient to download directly to the TV through its browser.
Troubleshooting and frequent errors
Even if you follow all the instructions, you can run into problems: the TV can’t see the phone, the image twitches or there is no sound. One of the most common reasons is to split networks at 2.4 GHz and 5 GHz with different subnets. Make sure that both devices are in the same network segment, or try temporarily disabling the Multi-SSID function in the router.
Sound problems often arise from content licensing protection (HDCP) restrictions. If you try to stream a video from a paid service and you see a black screen with a sound or an error message, it means that the mirroring method is blocked by the copyright holder, in which case only the native app on the TV or Google Cast technology will help.
If the phone stops seeing the TV after the firmware update, try resetting the network settings on both devices. On Xiaomi TV, you can do this in the Settings section. → Network and Internet → Network reset. The phone may be different, but it's usually in the Wi-Fi settings section, and it also helps to reboot a router that might have been stuck in the distribution. IP-address.
💡
90% of connection problems are solved by restarting the router or reconnecting both devices to the same Wi-Fi frequency (only 2.4 or only 5 GHz).
