Modern technology makes it possible to transform any smartphone into a powerful multimedia center, but the small screen of a mobile device is often insufficient for comfortable viewing of movies, photos, or presentations. Xiaomi are in an advantageous position because the company is implementing advanced wireless data transmission protocols into its devices. The ability to stream images over Wi-Fi Provides access to content on a large display without the need to purchase additional cables or adapters.
The connection process can seem confusing due to the many names of technologies such as Miracast, Chromecast And DLNAHowever, once you understand the basic principles of wireless networking, you can easily control your screen content. It's important to understand that transmission quality directly depends on the speed of your router and the distance between devices. In this article, we'll cover all available connection methods in detail so you can enjoy high-definition content.
Wireless Transmission Technologies: Which One to Choose?
Before you begin setting things up, it's important to understand the terminology, as different applications and devices may use different protocols. Miracast — is a standard developed by the Wi-Fi Alliance that allows you to transmit images and sound directly from a device to a display without using a router, creating a direct Wi-Fi connection. TVs Xiaomi often use built-in support for this standard, which makes them compatible with most Android smartphones.
The second popular method is Google Cast (or Chromecast built-in). This technology allows you to not only mirror your screen, but also send commands to your TV to play content from the internet, which reduces the load on your phone's battery. Protocol DLNA It is used primarily for streaming multimedia files such as videos and music stored in the smartphone's memory.
What is the difference between Miracast and Chromecast?
Miracast mirrors your entire screen, showing everything that's happening on your phone, including notifications. Chromecast lets you play videos on your TV while using your phone as a remote control or even put it aside.
The method you choose depends on your goals: full mirroring is best for gaming and presentations, while built-in streaming features are ideal for watching YouTube or Netflix. Modern TVs Xiaomi at the base Android TV or PatchWall support all of the listed protocols simultaneously.
Preparing equipment and network
The foundation of a stable wireless streaming connection is a properly configured local network. The most important rule: both devices—the smartphone and the TV—must be connected to the same Wi-Fi network. If you have a dual-band router, make sure both devices are connected to the same frequency, preferably 5 GHz, as it provides higher throughput.
Check the software version on your TV XiaomiManufacturers regularly release updates that improve the stability of the Wi-Fi module and fix compatibility issues. To do this, go to the settings menu and find the section About device → System update.
☑️ Check before connection
⚠️ Important: If your router is configured with AP Isolation, devices will not see each other. This feature is often enabled on public networks, but at home, it should be disabled in the router settings.
Distance is also important to consider. To transmit high-resolution video (4K) without lag, the distance between the router and the signal receiver should not exceed 10 meters in an open area. Walls and household appliances can significantly weaken the signal.
Method 1: Built-in Cast feature on Android
Most Android smartphones have a built-in casting feature that doesn't require any third-party software. Xiaomi (MIUI) This feature is often called "Cast" or "Wireless Monitor." To activate it, pull down the notification shade and look for the corresponding icon.
Once turned on, the phone will begin searching for available devices on the network. Your TV should appear on the list. Xiaomi indicating the model. Click on it, and after a few seconds, the image from your smartphone will appear on the big screen. If you're using stock Android, the function may be called Smart View, Screen Cast or Broadcast depending on the manufacturer.
| Parameter | Meaning / Action | Note |
|---|---|---|
| Protocol | Miracast / Wi-Fi Direct | Works without internet |
| Delay | Low (50-100 ms) | Depends on the router |
| Quality | Up to 1080p / 60 FPS | Automatic adjustment |
| Sound | It is transmitted | Stereo |
It is important to note that when using this method, the phone screen must be turned on. Some models Xiaomi allow you to turn off the screen while continuing to play the video, but this depends on the MIUI firmware version.
Method 2: Using the Mi Remote app and Chromecast
For more advanced control and streaming of content from specific apps, the ecosystem is ideal Google Chromecast, built into TVs XiaomiUnlike mirroring the entire screen, here you select a specific video or photo to mirror. Make sure you have the app installed on your phone. Google Home or the corresponding application for controlling TV.
Open an app that supports streaming (e.g., YouTube, Netflix, VLC Player). Find the streaming icon (the rectangle with waves in the corner) and select your TV. This is the most energy-efficient option, as your phone only acts as a remote control, while the TV handles most of the video decoding.
The advantage of this method is the ability to control playback from your phone: you can pause, rewind, or change the volume without leaving the couch. Furthermore, the picture quality is often higher, as the TV downloads the stream itself from the network, bypassing the phone.
Stream from iPhone and iPad (iOS) to Xiaomi TV
Apple device owners are faced with compatibility issues because iOS uses a protocol AirPlay, which is not native to Android TV. However, many modern TVs Xiaomi have built-in AirPlay 2 support. Check for this feature in the TV settings section Settings → Apple AirPlay and HomeKit.
If there's no built-in support, don't despair. You'll need to install an AirPlay emulator app from the store on your TV. Google Play StorePopular options include AirScreen, AirPin or Receiver for AirPlayAfter installing such an application, the TV becomes visible to Apple devices.
To connect, open the item Screen mirroring in the iPhone's Control Center (swipe down from the upper-right corner). Your TV will appear in the list of available devices. Once connected, you can cast the entire screen or specific media files. Connection stability in this case is critically dependent on the quality of the Wi-Fi signal.
⚠️ Please note: When streaming from iOS via third-party apps, you may experience a slight delay in the cursor or sound on your TV. This isn't a problem for watching movies, but for fast-paced games, it's best to use a wired connection or special gaming modes.
Solving problems and increasing stability
Even with proper setup, problems may still occur: audio and video desync, image stuttering, or an inability to find a device. A common cause is a congested Wi-Fi channel. If your router operates in the 2.4 GHz band, try switching your devices to the 5 GHz band, which has less interference from neighboring networks and Bluetooth devices.
Another important aspect is energy saving. Aggressive battery settings on smartphones Xiaomi They may force the streaming process to close to save battery. Go to battery settings, find the app you're using for streaming, and set the operating mode. No restrictions.
If the image is choppy, try lowering the output resolution in your phone's settings or closing background apps that are consuming data. Restarting your router, which frees up RAM and resets network tables, also helps.
