Modern users rarely watch content exclusively on a small smartphone screen. It's much more enjoyable to immerse yourself in the cinematic experience on a larger display, using the power of a wireless network. If you have smart home appliances from a Chinese brand, the question of how to stream a movie from your phone to your TV via Xiaomi WiFi becomes a priority. Fortunately, the Mi TV ecosystem offers several effective methods for accomplishing this without the hassle of wires.
The main advantage of a wireless connection is the absence of tangled cables and the ability to control playback directly from your mobile device. DLNA And Miracast These are two key protocols supported by most models. However, for stable operation, it's crucial that both devices are on the same local network. In this article, we'll examine each available method in detail, review popular apps, and solve common connection issues.
Before you begin, make sure your router is broadcasting a 5 GHz signal, if possible. This will provide higher bandwidth, which is especially important for transmitting high-definition video. 4K without lag or buffering. Also, make sure your TV is updated to the latest software version available in your region.
Using the built-in screencasting feature
The fastest way to mirror an image is to use the native capabilities of the Android or iOS operating system. On Xiaomi smartphones, this feature is often called "Casting" or "Wireless Display." On Mi TVs, the corresponding module is usually enabled by default and waiting for a connection. You don't need to install third-party software for basic screen mirroring.
To get started, open the notification shade on your mobile device. Look for the icon labeled "Cast," "Smart View," or "Screen Mirroring." Once the search is activated, the system will begin scanning for available devices within range. Your device should appear in the list. Xiaomi Mi TV or Mi BoxClick on it to pair.
The connection process may take 5 to 15 seconds depending on the router's response speed. If you're using an iPhone, the technology will be called AirPlayOn the TV, you'll be asked to confirm the connection if there's a password, or simply allow access. After that, everything that happens on the phone screen will be displayed on the large display.
⚠️ Attention: Mirroring your smartphone's entire screen will drain your battery significantly faster. It's recommended to connect your phone to a charger while watching long movies.
Please note that when casting the entire screen, some apps may block the display of protected content due to DRM policies. In this case, you'll see a black image with audio playing. For such cases, it's best to use specialized player apps, which we'll discuss below.
Setting up DLNA via the built-in video player
Technology DLNA (Digital Living Network Alliance) allows you to stream media files over the network without duplicating your phone's entire interface. This is ideal if you've downloaded a movie and want to send it to your TV while still being able to use messaging apps on your smartphone. The built-in Mi Video player handles this task perfectly.
Open the file you want to play in your smartphone's default video player. In the playback controls, look for the icon resembling a screen with waves or a triangle—this is the "Cast" button. Tap it and select your TV from the list of available devices. The video will begin buffering and playing directly on the TV.
The advantage of this method is that the TV decodes the video stream itself, offloading the load from the phone's processor. You can minimize the player, answer a call, or switch to a browser, and playback on the big screen will not be interrupted. Picture quality will depend on the source file and the stability of the WiFi connection.
Some file formats may not be supported by the TV's built-in decoder. In such cases, the system will offer to cast the image through the phone's screen, which will revert to the Miracast method. For maximum compatibility, it is recommended to use universal formats, such as .mp4 or .mkv with codec H.264.
Video streaming apps: Mi Remote and others
Official app Mi Remote The Mi Remote is the primary control tool for the Xiaomi ecosystem. It allows you to not only change channels but also stream content. However, functionality may vary depending on the region and firmware version. Third-party solutions are often used for more advanced features.
One of the most popular and reliable tools is the application LocalCast or BubbleUPnPThese programs automatically find media files in your phone's memory and offer to send them to any compatible device on the network. The process is simple: launch the app, select the file, press the Cast button, and select the receiver.
- 📱 LocalCast: Supports a huge number of formats and subtitles, has a built-in browser for downloading.
- 📺 BubbleUPnP: A professional tool for advanced users that can stream to the cloud.
- 🎬 Xiaomi TV: Official management app, but file transfer features may be limited.
Using third-party players often solves problems with codecs and audio tracks. If your TV's built-in player doesn't recognize the audio track, DTS or AC3, a third-party sender can broadcast a pre-made stream, which the TV will be more likely to receive. This is especially relevant for older TV models, where support for modern audio formats is limited.
☑️ Pre-broadcast check
Broadcasting via Google Chrome browser
If you are watching a movie online through a browser on your phone, the built-in streaming function in Google Chrome This method is a great solution. It doesn't require installing any additional apps and works on most Android devices. It's especially convenient for watching videos from websites that don't have their own apps.
Open the Chrome browser on your smartphone and navigate to the video page. Tap the three dots in the upper-right corner of the menu and select "Cast." The system will prompt you to select a device. You can cast a single browser tab or your entire screen.
When you select the "Cast screen" option, the image is mirrored in real time. This creates a slight delay, noticeable when gaming, but perfectly acceptable for watching videos. A stable WiFi signal is essential, as this mode requires a fairly large data stream.
⚠️ Attention: When casting a browser tab, video may pause if you close the Chrome app or your phone goes into power saving mode.
For iPhone users, the situation is similar, but instead of Chrome, it's better to use the native AirPlay feature if your TV supports this protocol. Many modern Xiaomi models already have built-in AirPlay 2 support, making connecting Apple devices as simple and fast as possible.
Comparison of connection methods
The optimal method depends on your goals and the type of content. If you simply need to show photos or a presentation, a fast Miracast connection will suffice. For larger movies, it's better to use DLNA to save battery life. Below is a table to help you decide.
| Method | Quality | Load on the phone | Subtitle support |
|---|---|---|---|
| Miracast (Screen Casting) | Depends on the signal | High | Yes (as part of the screen) |
| DLNA (Video Player) | Original file | Low | Depends on TV |
| Google Cast | High | Average | Partially |
| AirPlay (iOS) | High | Average | Yes |
As can be seen from the table, DLNA It's more energy efficient, as the TV handles most of the decoding. However, this method requires the file to be pre-downloaded to the device's memory. Streaming via a browser or app is convenient for online content, but is more dependent on internet speed.
Troubleshooting connection and buffering issues
Even with proper setup, errors can still occur. The most common issue is that the TV isn't visible in the device list. First, check if "AP Isolation" is enabled on your router. If it's enabled, devices on the WiFi network can't "see" each other, blocking data transfer.
Another common issue is network desynchronization. Make sure your phone and TV are connected to the same network. Routers often emit two signals: 2.4 GHz And 5 GHzIf one device is on one frequency and another on another, in some router configurations they may not detect each other, even though they are technically on the same network.
- 🔄 Reboot: Turn your router, TV, and phone off and on again. This solves 80% of detection issues.
- 🔥 Antivirus: Check if your phone's firewall is blocking local connections.
- 📶 Signal: Make sure the WiFi signal strength on both devices is at least 2-3 bars.
If the video constantly stops due to buffering, try lowering the playback quality in the player or app settings. It's also worth checking whether the WiFi channel is overloaded by neighboring networks. In crowded apartment buildings, the 2.4 GHz channel is often clogged, and switching to 5 GHz solves the lag issue.
What to do if nothing helps?
Try resetting your TV's network settings. As a last resort, you can use a USB drive: copy the movie to the drive and connect it directly to the TV. This is the most reliable method for large, uncompressed files.
⚠️ Attention: MIUI TV and Android TV firmware interfaces may vary depending on the model year. If you don't see the described features, check the official documentation for your specific model in the "Support" section.
Frequently Asked Questions (FAQ)
Why doesn't my Xiaomi TV detect my phone when I try to stream?
Most likely, the devices are connected to different WiFi networks (for example, a guest network and the main network) or client isolation is enabled on the router. Also, check if the devices have different dates and times, as this could be interfering with authorization.
Is it possible to stream a movie from an iPhone to a Xiaomi TV wirelessly?
Yes, if your TV model supports AirPlay 2. If not, install an app from the Mi TV app store that emulates AirPlay reception, such as "AirScreen" or similar, on your TV.
Does streaming video affect internet speed for other devices?
When streaming online videos (YouTube, online cinemas), traffic goes over the internet, so speeds may drop. When streaming a local file via DLNA or Miracast, the internet is not used; traffic goes within the local network.
How to improve image quality during wireless transmission?
Use a router that supports the standard WiFi 5 (AC) or WiFi 6 (AX)Connect your TV to the router via a LAN cable, if possible, and leave your phone on WiFi. This will reduce the load on the wireless channel.
