Modern users are rarely content with watching content on a small smartphone screen. It is much more enjoyable to enjoy a favorite movie or photo shoot on a large display, especially if you have a smart TV from Xiaomi. Fortunately, wireless data technology allows you to do this without unnecessary wires and complex manipulations, using only a home Wi-Fi network.
The setup process can vary depending on your gadget’s operating system and the firmware version of your TV. In this article, we’ll take a look at all the available options, from built-in features to third-party apps that guarantee a stable picture, and learn how to avoid delays and audio desynchronization, which often happens when you’re not configured correctly.
Network requirements and equipment preparation
The foundation of successful broadcasting is a stable network connection. For Miracast or DLNA technology to work properly, it is critical that both the smartphone and the TV are on the same LAN, which means that both devices must be connected to the same router, preferably at 5 GHz, to transmit heavy video stream without buffering.
Check to have external device detection enabled on your Mi TV or Android TV. It is usually active by default, but after the firmware update, security settings may reset. Make sure both gadgets' software is updated to the latest version, as older Wi-Fi module drivers often contain compatibility errors.
⚠️ Note: If your router supports a guest network, do not connect your broadcasting devices to it. Customer isolation in the guest profile prohibits the exchange of data between gadgets within the network.
Not all routers are equally good at handling multicast traffic, which is used to transfer video. If you notice constant interruptions, try rebooting the router or temporarily disabling the VPN on your smartphone, as they can redirect traffic through external servers, breaking the local connection.
Use of the built-in Chromecast feature
The most popular and stable way to transfer images to Xiaomi TVs with Android TV shell is Google Chromecast technology. It is built directly into the system and does not require installing additional software on the TV. To get started, make sure that the smartphone has the Google Home app or the corresponding Google Play services.
The process of launching the broadcast is intuitive. Open an app that supports Casting (like YouTube, Netflix or Chrome), and find the rectangle icon with Wi-Fi waves in the corner. Once you select your Xiaomi TV from the list, the content will play on the big screen, and the phone will act as a remote control.
- 📱 Open the app with video on your smartphone and find the broadcast icon.
- 📺 Select your TV from the list of available devices on your local network.
- ⏸️ Use your phone to control playback, pause, or volume.
- 🌐 Make sure that both devices are using the same IP-subnet.
An important advantage of this method is that the TV itself downloads video streams from the Internet, unloading the smartphone processor, which allows you to watch video in high resolution 4K without significant battery consumption of the mobile device. However, if you want to broadcast the screen of a third-party application that does not have built-in Cast support, a different approach will be required.
💡
To save traffic when watching online videos via Chromecast, the TV uses your internet connection directly, so download speeds are independent of the power of the phone’s Wi-Fi module.
Screen broadcast via Miracast (Wireless Display)
If you want to bring to the big screen exactly what is happening on the display of a smartphone, including menus, games or applications without Cast support, you will need Miracast technology. In the Xiaomi ecosystem, this feature is often called "Wireless Display" or "Translation." It works at the system level and duplicates the video signal in real time.
On a PatchWall Mi TV or a pure Android TV, the signal reception function can be called differently. From the signal source menu (the button with the square and arrow on the remote), you need to select "Miracast", "Wireless Display" or "Screen Mirroring", after which the TV will go to the waiting mode of connection.
On Xiaomi smartphones with a MIUI or HyperOS shell, actions are performed as follows:
- 🔽 Lower the notification curtain and find the "Translation" or "Cast" option".
- 🔍 Click on it and the phone will start searching for available displays within Wi-Fi range.
- 📺 Tap the name of your TV to establish a connection.
- 🖥️ Image from the phone will instantly appear on the TV screen.
⚠️ Note: Miracast can cause a slight delay between the action on the phone and the display on TV. This is normal for this technology and is not suitable for dynamic shooters.
☑️ Checking before connecting Miracast
Specificity of connecting iPhone (iOS) to Xiaomi TV
Apple owners should not despair, as modern Xiaomi TVs support the AirPlay 2 protocol.This allows you to broadcast screen or video from the iPhone and iPad natively, without installing "crutches". However, on some TV models, AirPlay support may be hidden or require activation.
To start, check if AirPlay is available in your TV settings. Go to Settings → Apps → Embedded Apps → AirPlay and make sure the feature is enabled. If standard methods fail to connect, you can use the official application from Xiaomi — or third-party counterparts from the App Store.
The process of connecting to iOS device looks like this:
- Open the "Control Point" on the iPhone (swipe down from the upper right corner).
- Click on the "Screen Repeat" button (two intersecting rectangles).
- In the list, select your Xiaomi TV.
- If necessary, enter the code displayed on the TV screen in the field on the smartphone.
It’s worth noting that the quality of transmission through AirPlay is usually higher than through Miracast, thanks to better codec optimization in the Apple ecosystem.The picture remains clear, and sound desynchronization is extremely rare with a good router signal.
What to do if your iPhone can’t see TV?
Third-party applications for enhanced capabilities
Staff funds are not always enough, especially if you want to stream files of specific formats or control a computer connected to a TV. APK-You can install universal media servers, and the leaders in this niche are Web Video Caster and BubbleUPnP applications.
These programs work on the DLNA principle and allow you to feed the TV almost any video file stored in the phone's memory or on a cloud drive. They independently convert the stream on the fly if the TV does not support the original file codec, which solves 99% of the problems with the black screen when you try to run a video.
Comparison of popular broadcasting methods:
| Method | Quality. | Delay. | Compatibility |
|---|---|---|---|
| Chromecast | High (up to 4K) | Low. | Android / iOS |
| Miracast | Depends on the signal. | Medium | Android / Windows |
| AirPlay 2 | Very high. | Minimum | iOS / macOS |
| DLNA (Annexes) | Maximum. | Absent. | All platforms. |
Using dedicated players like VLC for Android also yields great results. From the file playback menu, select the "Output" option and find your renderer (TV), which is the perfect way to view large local files without having to pump in advance.
💡
Third-party applications players often cope with heavy files better than built-in tools, as they have their own codecs and buffering.
Problem Solving and Quality Customization
Even if you set up correctly, users may encounter artifacts, twitching images or no connection at all. Most often, the problem lies in the oversaturation of the airwaves of Wi-Fi by neighboring routers, in which case it is recommended to manually change the channel in the router settings to a less loaded one (for example, 1, 6 or 11 for 2.4 GHz).
If the video is constantly stopped for buffering, try to reduce the quality of the stream in the settings of the source application. It is also worth checking whether the TV is not limited by background processes. In the Settings menu → About TV → Status you can see the current connection speed; for 4K it should not fall below 25 Mbps.
⚠️ Note: Do not attempt to stream video in resolution 4K 2.4 GHz bandwidth of this range is physically insufficient for a stable stream of high quality.
In some cases, cleaning the cache of Google Play services and the YouTube app on your TV helps. Go to Settings → Apps → System applications, find what you want and select Clear Cache. This eliminates software conflicts that accumulate over time.
