Modern Xiaomi Smart TVs turn the living room into a real multimedia center, but the device’s full potential is only revealed when combined with a smartphone. The ability to broadcast an image from a mobile screen to a large diagonal opens up access to thousands of apps, photo archives and games that are not preinstalled on the Android TV operating system itself. Users often look for ways to duplicate content, but face a variety of protocols and settings, which can cause confusion.
The connection process depends on many factors: your phone model, the version of the MIUI or HyperOS operating system, and the year of the TV release. In some cases, standard functionality is enough, in others you will need to install third-party software or even use physical adapters. It is important to understand that a wireless connection requires stable operation of the router, whereas wired one guarantees no delays, which is critical for dynamic games.
In this article, we will take a look at all the available video streaming methods, learn about the nuances of Miracast and DLNA protocols, learn how to configure the broadcast for iOS devices, and understand how to eliminate sound desynchronization. We will not use complex technical terms without explanation, so that anyone can customize their Xiaomi TV in a few minutes.
Basic requirements and equipment preparation
Before you start setting up, you need to make sure that your equipment meets the minimum technical requirements. The fundamental condition for most wireless methods is that the devices are on the same LAN. If your phone is connected to 4G/5G mobile Internet and your TV is connected to Wi-Fi, the communication between them will not be established, because they are on different subnets.
Older Xiaomi Mi TVs may have an outdated version of Android TV that does not properly support new video coding standards. It is recommended to check for updates in the settings menu, as the manufacturer often releases patches that improve the stability of the Cast protocol.
☑️ Checking before connection
There is a common misconception that broadcasting requires Internet. In fact, Direct Wi-Fi or Miracast technology does not require a global network, it is enough that the router simply distributes the Internet. IP-But if you're planning to stream content from online cinemas, access to the World Wide Web is definitely a must.
💡
For maximum response speed in games, use a 5GHz router, as it is less crowded with neighbor networks and provides higher bandwidth.
Use of the built-in Translation (Miracast) function
The most versatile way that works on most Android smartphones is through the built-in Translation or Wireless Monitor feature. In the MIUI shell, this tool is often hidden in the Control Panel or Connections and Sharing menu. Miracast technology allows you to duplicate the screen in real time without the need to install additional software.
The activation process is usually as follows: unlock your phone, lower the notification curtain, and find an icon called Translation, Projection, or Cast. Once clicked, the system will start searching for available devices. Your Xiaomi TV should appear on the list, possibly with a TV or device model.
If automatic search doesn't work, try manually running the search through the display settings. Some TV models require you to pre-start the "Miracast" or "Wireless Display" app on the TV itself to make it visible to external devices, especially for models released a few years ago.
What to do if you can’t see the TV?
It is worth noting that when using this method, the phone screen is completely copied to TV, which means that any notifications, incoming calls or messages will be visible to everyone in the room, and the aspect ratio may not match, and black bars may appear on the sides of the image if the screen resolution differs.
Broadcasting via Google Home and Chromecast
Google’s ecosystem offers a more advanced Chromecast built-in protocol that is often more stable than standard Miracast, requiring Google Home, which can be downloaded from the Play Market, a method that not only duplicates the screen, but also manages media content, turning the phone into a remote control.
Once you install the app, launch it and log in to your Google account. The program will automatically detect a Xiaomi TV connected to the same network. Click on the device icon and then select the "Cast my screen" button. The system will warn you that the sound and image from the phone will be played on the TV.
The main advantage of this method is the ability to manage content, so you can turn down an app on your phone, respond to messages, or even lock the screen, and the video streaming will not be interrupted, which is especially useful when watching movies through a browser or streaming services that do not have a native app on the TV.
| Characteristics | Miracast | Chromecast (Google Home) |
|---|---|---|
| Stability | Medium, possible breaks | High, buffering |
| Battery consumption | Tall (screen on fire) | Medium (can be turned off screen) |
| Video quality | Depends on the strength of the signal. | Adaptive, up to 4K |
| Management | Only from the phone. | From the phone and remote. |
It’s important to consider that Chromecast requires Google services to be available on a broadcast device, and on new Huawei smartphones or devices released for the Chinese market without GMS, this method may not work without additional manipulations to install services.
💡
Chromecast is preferred for watching videos, as it less loads the phone’s processor and allows you to use the gadget for other tasks while watching.
Connecting Apple devices (AirPlay) to Xiaomi TV
iPhone and iPad owners often face difficulties, as the native AirPlay feature doesn’t always work correctly with Android TVs out of the box. However, modern Xiaomi Mi TV models often have built-in AirPlay 2 support. To check this, go to the TV settings and find the section associated with Apple AirPlay and make sure the feature is activated.
If there is no built-in support or it is not stable, the solution is to install a third-party app on the TV itself, the most popular and reliable option is the AirScreen or AirPin app, which can be found in the Google Play Store directly on the TV.
After you install the app on your TV, open it. QR-code and device name. Now on your iPhone, open Control Point (swipe down from the top right corner or up from the bottom, depending on the model) and click Screen Replay. From the list, select the name of the app running on your TV.
⚠️ Note: Free versions of AirPlay emulator apps may display a banner ad on your TV screen, which is normal for free software, but can be distracting when watching movies.
The quality of transmission through AirPlay emulators on Android TV is usually very high, with minimal latency. This allows you to even play mobile games on the big screen, although for shooters, a delay of 0.5-1 second can be noticeable.
Wired connection via HDMI and adapters
When wireless connectivity is impossible due to poor signal or maximum image quality is required without compression, wired methods come to the rescue. To connect your smartphone to Xiaomi TV via cable, you will need a special adapter, since there is no direct HDMI input in your phones.
Owners of modern flagships with a USB Type-C port that supports USB 3.1 or Thunderbolt can use a Type-C to HDMI adapter. This method transmits a digital signal without loss of quality and does not create a burden on the Wi-Fi network. However, budget phones often have a USB 2.0 port that does not support video transmission (MHL or DP Alt Mode).
For devices with a Micro-USB port or phones without video output support via USB-C, there are special adapters with MHL (Mobile High-Definition Link) technology, which require additional power, usually via a second USB cable, since the port power is not enough to transmit a video signal.
Connection sequence:
1. Connect the HDMI cable to the TV and adapter.
2. Connect the power to the adapter (via USB).
3. switch the signal source to the TV to HDMI mode (Input button).
4. The image must appear automatically.The main advantage of wired connectivity is the complete absence of latency (input lag), which makes this method the only viable option for cloud gaming or real-time games, where the count goes on milliseconds. In addition, the phone in this mode can charge if the adapter has a charging port (PD Pass-through).
Why is there no sound when connecting the cable?
Broadcasting through DLNA and third-party applications
If your goal is not to duplicate the screen, but to launch a specific video file or photo stored in the phone’s memory, the most effective protocol will be the one that will be used to do so. DLNA. It doesn't require a constant connection of screens, but only transmits a data stream to the TV media player, and for this, the phone must have an application controller, for example, a controller, VLC For Android, BubbleUPnP or a standard gallery with Cast support.
Consider the process using the popular VLC player. Open a video file on your phone, click on the broadcast icon (rectangle with waves) in the corner of the screen. The player will find your Xiaomi TV on the network. Once you select the device, the video will play on the TV, and the phone can be used as a remote: pause, rewind or adjust the volume.
There are many specialized streaming apps, such as LocalCast or Web Video Caster, which are particularly useful because they allow you to "send" to your TV a video you're watching in your browser on your phone, even if the site blocks the embedded broadcast.
⚠️ Attention: When in use DLNA Make sure the video file format is supported by the TV if the TV cannot decode the audio track (e.g, DTS or AC3), You will see a picture without sound, even if the file is played.
The advantage of DLNA is that it saves resources, and the phone is just a remote, and the TV processor decodes and renders the video, and it allows you to watch high-resolution 4K HDR video on even the most powerful smartphones without draining their battery in 20 minutes.
Resolving and eliminating delays
Even with the right setup, users can face problems: dissynchronization of sound and video, periodic twitching of the image or a complete disconnection. Most often the cause lies in an overloaded Wi-Fi channel. If the router is running at 2.4 GHz, it can be affected by microwaves, bluetooth headsets and neighbors' networks.
To diagnose the problem, try to bring the phone closer to the router, if the quality is improving, then the signal is too weak, and it is worth checking whether the phone is running background downloads of large files that “clog” the channel. In the router settings, you can try to change the broadcast channel to a freer one.
Another common reason is energy saving: Aggressive MIUI settings can kill the broadcast process in the background to save power. Go to the battery settings, find the app you are using (like Google Home or YouTube), and set No Limits mode.
⚠️ Warning: If you feel a great delay between tapping on your phone screen and acting on your TV when broadcasting games, the wireless method won't work for you. HDMI-cable or reduce the quality of graphics in the game to improve FPS.
In some cases, resetting network settings on both devices helps. Delete the Wi-Fi network profile on your phone and TV, and then reconnect by entering your password. IP-Addresses and Resets Possible Network Conflicts.
