Modern Smart TV Xiaomi's new home theater systems transform your living room into a true cinema, eliminating the need to fumble for cables and adapters. Wirelessly streaming images from your mobile device to the big screen has become the de facto standard, providing a comfortable viewing experience in high definition. Users no longer have to huddle in front of a small smartphone display when they can enjoy their favorite movies on a 50-inch or larger screen.
The process of synchronizing devices is based on technology Miracast and the Google Cast protocol, which are built into the Android TV operating system used in most Xiaomi TVs. This means you don't need to buy expensive additional equipment or complex adapters to get started. Simply connect both devices to the same local network, and you can start streaming instantly.
However, despite the apparent simplicity, users often encounter nuances when setting up a router or choosing the right intermediary app. In this article, we'll cover all connection methods in detail, from standard system functions to specialized software. You'll learn how to eliminate audio lag and achieve a stable picture without compression artifacts.
Technical requirements and equipment preparation
Before starting setup, it's crucial to ensure your equipment meets the basic requirements for stable wireless protocol operation. The primary requirement is the module. Wi-Fi Both devices support 5 GHz, although 2.4 GHz is also acceptable but may offer lower throughput. Xiaomi TVs are typically equipped with dual-band modules, allowing users to select less congested airwaves.
The second key factor is the operating system version. Screencasting has been available on Android smartphones for quite some time, but for modern codecs to work, it's recommended to have the version Android 9.0 iPhone owners are also in luck: Xiaomi TVs support the AirPlay protocol, allowing you to stream content from iOS devices without installing third-party software on the TV itself.
⚠️ Note: If your router broadcasts the same network name (SSID) for both 2.4 GHz and 5 GHz frequencies, devices may "hop" between them, causing connection drops. For stable 4K movie streaming, it's best to have your phone and TV connected to the 5 GHz band.
It's also worth checking the amount of free RAM on your smartphone. The process of encoding a video stream in real time requires processor resources. If your phone is overloaded with background tasks, the picture on your TV may flicker or become out of sync with the sound. Close unnecessary apps before starting a movie to ensure smooth playback.
Using the built-in "Broadcast" function (Miracast)
The easiest and fastest way to display an image is to use the native Android operating system feature, often called "Cast," "Smart View" (on Samsung), or "Wireless Monitor." In Xiaomi TVs, this technology is implemented via a built-in receiver, which doesn't require installing apps on the TV if you use the standard launcher.
To activate the mode on your Xiaomi TV, go to the signal sources menu or find the corresponding app in the program list. It may be called Wireless Display, Miracast or simply BroadcastOnce launched, a connection waiting message will appear on the screen, and the device will become visible for searching within the network range.
On a smartphone, the algorithm of actions looks like this:
- 📱 Swipe down to open the quick settings panel and find the "Cast" or "Projection" icon.
- 📺 Select your TV from the list of available devices Xiaomi Mi TV.
- ✅ Confirm the connection on the TV screen if a request for access permission appears.
Once paired successfully, your phone's screen will be mirrored to your TV. This means you can scroll through your social media feed, play games, or watch videos from any app. However, it's important to remember that this mode mirroring consumes more battery power from your smartphone because the video stream is constantly transmitted, even if there is a static image on the screen.
Why might Miracast not work?
This feature may not activate if AP Isolation is enabled on your router. This setting prevents devices on the same Wi-Fi network from "seeing" each other. Disable it in your router settings (usually in the Wireless Settings section).
Streaming via Google Home and Chromecast built-in
A more advanced and energy efficient way is to use technology Chromecast built-in, which is built into the Android TV platform of Xiaomi TVs. Unlike Miracast, the phone doesn't cast the entire screen, but rather acts as a remote control, sending the TV a link to the video stream. The TV automatically downloads content from the internet, saving battery life and reducing the load on the Wi-Fi network.
To implement this method you will need the official application Google Home, which is available in the Play Market. After installation and authorization using the same Google account as your TV, the system will automatically detect your Xiaomi TV. In the app, select the device and click the "Cast Screen" button or use the cast button within supported apps (YouTube, Netflix, Kinopoisk).
Advantages of using Chromecast over direct mirroring:
- 🚀 High picture quality without compression, as the TV takes the stream directly.
- 🔋 Minimal smartphone battery consumption while watching.
- 📱 The ability to use the phone for other tasks (calls, instant messaging) without interrupting the movie.
It's important to note that for this feature to work, both devices must be connected to the same subnet. If you have a complex network infrastructure with guest networks, make sure the phone and TV aren't isolated from each other by router rules.
Specialized apps for Xiaomi and Android TV
Built-in tools don't always work perfectly, especially if you want to stream files from your phone's local storage or use specific video formats. In such cases, third-party aggregator apps come to the rescue, often offering more flexible codec and buffering settings.
One of the most popular solutions is the application Cast to TV - XCast or Web Video CasterThese programs can "extract" video streams from browsers and players, convert them on the fly into a format understandable to the TV, and send them to DLDNA or Chromecast receiver. This is especially relevant for watching videos from cloud storage services or websites that don't officially support TV versions.
Algorithm for working with such applications:
- Install the selected application on your smartphone from the app store.
- Launch the program and wait until the Xiaomi TV is detected on the local network.
- Select a file or link and the image will appear on the big screen.
Some apps also allow you to control playback using voice commands or have a built-in browser with an ad blocker, making viewing content from untrusted sources more convenient. However, be wary of free versions, which may contain excessive ads.
Resolving lag and image quality issues
Even with ideal settings, users may experience audio and video desynchronization or occasional image stuttering. This is most often caused by a congested Wi-Fi channel or insufficient data routing speed between the device and the router. This is especially noticeable when playing 4K HDR content.
To diagnose the problem, you can use the table of symptoms and possible solutions:
| Symptom | Probable cause | Solution method |
|---|---|---|
| The picture is twitching | Slow Wi-Fi speed | Switch to 5 GHz and move closer to the router. |
| There is no sound on the TV | Incorrect audio output | Check the audio settings in the source application |
| Black screen | HDCP protection | Use official apps (Netflix, YouTube) |
| Control delay | High ping | Close background downloads on your phone and PC |
It's also worth considering that some streaming services (Netflix, Amazon Prime) use copy protection. HDCPIf you try to stream protected content via screen mirroring (Miracast), the TV will display a black screen with audio. In such cases, the only solution is to use the built-in "Cast" button within the video service app.
⚠️ Note: Xiaomi TV interfaces (PatchWall or Android TV) may be updated, changing menu item names. If you don't see the described options, check the latest documentation in the "About TV" or "Help" section of your device's settings.
Frequently Asked Questions (FAQ)
Is it possible to connect an iPhone to a Xiaomi TV wirelessly?
Yes, modern Xiaomi TVs support AirPlay 2. You don't need any additional set-top boxes. Simply open "Screen Mirroring" in your iPhone's Control Center and select your TV from the list. Make sure both devices are on the same Wi-Fi network.
Why can't my phone detect my Xiaomi TV?
Check that both devices are connected to the same Wi-Fi network (it's important that it's not a guest network). Also, make sure the TV is running a signal-receiving app or is in connection standby mode.
Does phone connection affect internet speed?
When using Chromecast (where the TV streams itself), there's practically no effect. When using screen mirroring (Miracast), the phone actively transmits the video stream, which can take up a significant portion of the bandwidth, especially in high definition.
