Modern Xiaomi and Redmi TVs have powerful features that allow you to turn a conventional display device into a full-fledged multimedia center. Often there is a situation when the content on the screen of a smartphone is much more than can accommodate a gadget display, and you want to share it with your family on the big screen. wireless data technology solves this problem in seconds without having to buy additional consoles.
In this article, we will discuss how to configure screen broadcasting in different ways, using the built-in capabilities of the Android TV system and standard multimedia transmission protocols. You will learn about the intricacies of network configuration, the features of different applications and ways to eliminate delays. Understanding the principles of Wi-Fi Direct and Miracast will allow you to enjoy content in the maximum quality.
Before we get to the practical steps, it's worth noting that connection quality is directly dependent on the stability of your home network.High-definition wireless video streaming requires a significant channel bandwidth, especially if you plan to watch 4K content. Make sure the router supports 802.11ac standards or newer for the best result.
Technology of wireless image transmission
Xiaomi uses several basic protocols to transfer images from its smartphone to its TV, each with its own characteristics, the most common being Miracast (often labeled as Wireless Display), which allows you to create a direct connection between devices without the need for a router, which provides minimal latency, which is critical for gaming.
Another popular standard is Google Chromecast, built into the shell of Android TV. Unlike Miracast, here the smartphone acts only as a remote control, sending a command to start the stream, while the TV downloads content from the Internet on its own, which reduces the load on the phone’s battery and frees it for other tasks.
Also worth mentioning is the DLNA protocol, which is more commonly used to transfer media files (photos, videos, music) than full screen cloning. Although some emulator applications allow for the broadcast of an image via DLNA, this is not their primary function and is often accompanied by artifacts.
⚠️ Note: When using Miracast in direct connection mode (without a router), your smartphone may temporarily lose access to the Internet, as the Wi-Fi module switches to work with the TV.
What is the difference between casting and dubbing?
Preparation of equipment and network
The first and most important condition for successful synchronization is to have both devices on the same LAN, which means that both your smartphone and Xiaomi TV must be connected to the same router. If you have a dual-band router, make sure that both devices can see each other, even if they are connected to different frequencies (2.4 GHz and 5 GHz), although 5 GHz is preferred for video streaming.
Check the software version on your TV. Often manufacturers release updates that improve the stability of the Wi-Fi Direct module. To do this, go to the Settings menu, select System About and click System Update. Having the latest security patches and drivers eliminates many potential connection errors.
☑️ Checking before connection
If your router is configured with Client Isolation, devices will not be able to find each other even on the same network, a feature that is usually enabled in offices for security, but at home it must be disabled in router settings via the web interface.
Use of the built-in Chromecast feature
Owners of Xiaomi TVs with Android TV have a huge advantage – built-in support for Google Cast technology. You do not need to install any additional apps on the TV, just that the smartphone has installed the Google Home app or the corresponding functions are built into the system (for example, MIUI or HyperOS).
To start the broadcast, open the app you want to show content (like YouTube or Netflix) and click on the broadcast icon (a rectangle with waves in the corner). Select your Xiaomi TV from the list. The image will appear on the big screen, and the phone will turn into a remote control.
If you want to stream your smartphone screen (games, browser, photo gallery), open the Google Home app, find your TV in the list of devices and click the Broadcast button.
💡
To reduce latency when playing through Chromecast, close the background apps on your smartphone that consume traffic and get close to the router.
It’s important to understand that the quality of the image when using Chromecast depends on the speed of the Internet, since the flow often goes not from the phone, but directly from the service servers to the TV.
Miracast broadcast on TVs without Android TV
Not all Xiaomi models run on Android TV; some use their own PatchWall shell or other Linux-based systems. In such cases, the main method of connection is Miracast technology (in the TV menu it can be called "Wireless Display", "Screen Mirroring" or "Duplicate screen").
You need to activate the standby mode on the TV, usually through the signal source menu (Input button or Remote Source), where you need to select the Wireless Display option, the screen will display a message about waiting for the connection and, possibly, the screen will show a message about waiting for the connection and, PIN-code.
On a Xiaomi smartphone (MIUI/HyperOS), open the control panel (curtain) and find the Broadcast or Wireless Monitor. The phone will start searching for available devices. Once your TV appears on the list, click on it to pair.
| Parameter | Miracast | Chromecast |
|---|---|---|
| Router dependency | No requirement (direct connection) | Required. |
| Delay (Latency) | Low. | Medium/High |
| Battery consumption | High-pitched | Low. |
| Image quality | Depends on the distance. | Depends on the Internet. |
The advantage of Miracast is that it streams video directly, making it ideal for presentations or games where reaction is important, but if communication is interrupted, the image can "crumbling" into artifacts.
Configuring through third-party applications
If the built-in methods don't work or you want to get advanced functionality (like mouse control from your phone), you can use third-party solutions. One of the most popular and reliable applications is Web Video Caster or LocalCast, which allows you to stream not only videos, but also files from local storage.
Install the app on your smartphone and, if required, its Android TV version on your TV (via the Google Play Store on TV). Once launched, both devices should automatically detect each other on the local network.
In the app on your phone, select a file or video link, and as a playback device, specify your Xiaomi TV. the app will create a tunnel for data transfer, supporting many formats that the native TV player may not “understand”.
⚠️ Note: Some free versions of apps may contain ads that will be displayed on the TV screen while connecting or playing.
Using third-party software is especially important if you need to stream content from applications that block the standard HDCP (copy protection) function during normal screen duplication.
Resolving and eliminating delays
One of the most common problems is that you can desynchronize sound and image, or you can have jerks when you play it, and most often it's because you overload your Wi-Fi channel. IP-cameras or other devices, bandwidth may not be enough for the video stream.
Try rebooting your router and TV. The banal action often clears the cache of network modules and eliminates software failures. Also make sure that the TV turns off energy-saving modes, which can reduce the performance of the Wi-Fi module to save electricity.
If there is an image and no sound, check the audio output settings in the app itself or in the TV settings (Settings → Sound → Audio output).
In cases where nothing helps, you can try resetting the network settings on your TV. Go to Settings → Network → Network Reset. This will delete stored Wi-Fi passwords, but often solves problems with device detection protocols.
