Modern Xiaomi TVs, powered by Android TV or proprietary PatchWall, turn a regular screen into a multimedia center, but it often becomes necessary to bring content from a mobile device. Owners of Xiaomi, Redmi and POCO smartphones, as well as users of iPhone and other Android gadgets, regularly face the question of how to organize a stable and high-quality image transfer, this may be necessary for viewing family photos on the big screen, showing a presentation or just playing mobile games with improved graphics and sound.
The setup process depends on many factors: operating system version, TV model (Mi). TV, Redmi TV), And the kind of content you plan to share, and there are native Android features, third-party apps, and wired solutions through the Internet. HDMI-In this article, we will take a detailed look at all the available methods so that you can choose the best option for your situation and enjoy the content without delay.
Before we get to specific instructions, it’s important to understand the basics of wireless protocols. Most modern broadcasting methods, such as Miracast and Google Cast, require both devices to be on the same local Wi-Fi network. This is a fundamental condition that requires device detection. If your router distributes a network at 2.4 GHz and 5 GHz with different names, make sure that the TV and smartphone are connected to the same frequency, as some older TV models may not see devices in the adjacent range.
Wireless broadcasting via built-in Miracast
The most common and frequently used method is to use Miracast technology, which in the Xiaomi ecosystem is often called Translation or Wireless Display, which allows you to duplicate the smartphone screen on the TV in real time, which is ideal for navigating the phone menu, showing work documents or games. You do not need to install additional applications to get started, since the feature is built into the MIUI or HyperOS shell.
To activate the reception mode on the TV, you need to go to the application menu and find the standard Broadcast app (or Mi Remote in some regions where the function is built in). After starting the application, the TV will go into standby mode. On the smartphone, you should open the control panel (curtain) and click on the Translation button or find the appropriate item in the connection settings. The system will start searching for available devices, and in a few seconds you will see the name of your Xiaomi TV.
It’s worth noting that picture quality and latency are directly dependent on the power of your Wi-Fi router and the distance to it. If you plan to stream video in high resolution 4K, make sure that both devices support 802.11ac or later. If artifacts appear or sound is out of sync, try approaching the router or switching the network frequency.
It is important to consider that when using Miracast smartphone can significantly heat up, as the process of encoding video is in real time.
⚠️ Warning: Long-term high-resolution streaming via Miracast can lead to overheating of the smartphone and accelerated battery discharge, so it is recommended to keep the device on charge.
Using Google Chromecast built-in technology
Most modern Xiaomi TVs have built-in support for Google Cast technology, making them full-fledged Chromecast devices. Unlike Miracast, which simply duplicates the screen, Chromecast allows you to send a command to the TV to play content directly from the Internet, which frees up the smartphone and saves its charge.
To use this feature, make sure your TV has Android TV installed and updated. In your TV settings, go to Settings → Apps → All Apps → Google Cast and check that the service is active. On your smartphone, open the app you want to stream (like YouTube), click on the rectangle icon with waves in the corner and select your TV from the list. The picture will appear on the big screen, and the phone can be used as a remote or lock.
💡
If the TV doesn’t appear in the list of available Cast devices, try restarting the router and make sure that Bluetooth and geolocation are enabled on the smartphone and TV, as they are used for initial detection.
The advantage of this method is that you can control playback from multiple devices at once. You can run video on your phone and then transfer control to another user's tablet. Google Cast also provides a more stable connection and better image quality when watching online video, since the data flow directly from the server to the TV, bypassing the smartphone.
But it's worth remembering that app compatibility is important. Not all programs support Cast, and in such cases, the broadcast button may not be available, so you can use Screen Translation within the Google Home app itself, which will allow you to duplicate the entire Android interface, but with a slightly higher latency than the native Cast.
Streaming from iPhone and iPad via AirPlay
Apple owners often wonder how to stream content on Xiaomi TV, as native AirPlay support is absent in Android. However, Xiaomi has solved this problem by introducing AirPlay 2 protocol support in its new TV models. This allows iPhone, iPad and Mac users to stream image and sound to the TV without having to buy additional equipment such as Apple TV.
To check for support, go to the settings of your Xiaomi TV and look for the section associated with AirPlay or Apple HomeKit. If this option is not on the menu, your model may need a firmware update. On your Apple device, open Control Point, click Screen Replay, and select your TV. To connect, you may need to enter a four-digit code that appears on the TV screen.
| Parameter | Miracast (Android) | Google Cast | AirPlay 2 (iOS) |
|---|---|---|---|
| Type of transmission | Screen duplication | Streaming | Duplication and flows |
| Dependence on the phone | High (screen active) | Low (can be turned off) | Medium |
| Video quality | Depends on the Wi-Fi signal. | Stable (up to 4K HDR) | High (up to 4K) |
| Delay (Latency) | Minimum | Medium | Minimum |
If your Xiaomi TV model doesn't natively support AirPlay, there are workarounds. APK-An emulator application file, like AirScreen or ApowerMirror. These programs create a virtual receiver that tricks the iPhone into thinking it's connected to an Apple device. TV Requires permission to install from unknown sources in Android security settings TV.
Wired connection via HDMI and USB-C
When the wireless connection is unstable or the maximum image quality without compression is required, wired methods come to the rescue. HDMI-Cable is the most reliable way to broadcast an image on Xiaomi TV. For modern smartphones with a port USB Type-C Adapter: You will need a Type-C adapter) USB-C to HDMI.
It is important to understand that not all smartphones support video output via USB. The technology required for this is called DisplayPort Alt Mode. flagship models Xiaomi and Redmi usually have this support, while budget devices can not transmit video signals, limited only to charging and transferring data. You can check the specification of your smartphone on the official website of the manufacturer or in the technical documentation.
☑️ Checking readiness HDMI-connection
The connection process is extremely simple: connect the adapter to the smartphone, connect HDMI-cable to the adapter and TV, then switch the signal source to the TV to the appropriate port (for example, HDMI 1) The image should appear automatically. If this does not happen, go to the settings of the smartphone in the section "Screen" or "Connections" and activate the external output.
This method also allows you to use the smartphone in desktop mode, if such a function is provided by the shell. MIUI. You can connect the keyboard and mouse to USB-Hub and turn your phone into a full-fledged computer for working with documents on the big screen.
⚠️ Note: When using long-term HDMI-cables (more than 3 meters) without an active signal amplifier may reduce the quality of the picture or periodic breaks of the connection.
Third-party applications for enhanced capabilities
If standard tools aren’t enough, the Google Play store on Xiaomi TV offers a variety of third-party apps that extend the functionality of the broadcast. One of the most popular is Web Video Caster, which allows you to stream video files directly from your smartphone browser to your TV, supporting formats that are not played by the native TV player.
Another powerful solution is LocalCast or BubbleUPnP. They let you create media libraries from files stored on your phone or in cloud storage (Google Drive, Dropbox), and stream them to your TV, which is especially convenient if you have a large archive of family videos in MKV or AVI formats that the TV may not see through a standard conductor.
For gamers who want to play mobile games on a TV with minimal latency, there are specialized applications that use Wi-Fi Direct to create a direct channel between devices, bypassing the router. However, such solutions often require installing a companion app on both the TV and the smartphone.

Solving Connection Problems
Despite the ease of setting up, users often face technical difficulties. One of the most common problems is that the TV can't see the phone. 90% of the time, this is done by checking that both devices are on the same subnet. If you have a dual-band router, make sure you don't split the 2.4 GHz and 5 GHz networks into different names (SSIDs), or connect both devices to one of them explicitly.
Another common problem is intermittent image or audio dissynchronization, which can be caused by overloading the Wi-Fi channel with neighboring networks, which can help change the channel in the router’s settings to a less busy one (for example, 1, 6 or 11 for 2.4 GHz), and it is also worth checking whether the TV is power saving mode, which can limit the operation of the Wi-Fi module.
If you use VPN On a smartphone, the broadcast may not work because local traffic is redirected through a remote server. VPN-linkage.
⚠️ Warning: Antivirus programs and firewalls on your smartphone can block the ports needed to detect devices.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the absence of interference in the air, so the router must be in line of sight or through one wall.
