Modern Xiaomi Mi TVs and Xiaomi Mi Box are powerful multimedia hubs, but there is often a need to stream content directly from a mobile device. Users are looking for ways to connect the phone to a TV to enjoy photos, videos or games on the big screen. This is especially true when built-in Smart TV apps are not enough or you need to access specific content from a smartphone.
There are several effective synchronization methods, each with its own advantages depending on your goals: You can use wireless technologies like Miracast and Google Cast, or you can use a wired connection over HDMI for maximum stability. The choice of the specific method depends on your gadget model, the version of the operating system and the available ports on your TV.
In this article, we will take a closer look at all the connectivity options available, focusing on the nuances of setting up MIUI and Android TV. You will learn how to avoid image delays, solve codec compatibility issues, and ensure the best picture quality.
Preparation of equipment and network for synchronization
Before starting the process, make sure that both devices are in the same network conditions. For wireless data, it is critical that the smartphone and Xiaomi TV are connected to the same Wi-Fi network. If the router supports dual-band mode, it is better to use a 5 GHz frequency, as it provides higher bandwidth.
Check the software's up-to-date on both devices. Outdated firmware versions may contain bugs that prevent devices from being detected on the local network. Go to your TV settings via the Settings path → About TV → System information and check for updates.
⚠️ Note: If your router splits 2.4 GHz and 5 GHz networks into different SSID (Network names, make sure that both devices are connected to one of them, otherwise they may not be able to see each other.
Also worth paying attention to is router mode: Some providers or security settings may isolate client devices from each other (AP Isolation), in which case direct connection between the phone and the TV will not be possible, even if they are on the same network.
Wireless connection via built-in broadcast function
The simplest and most popular method is to use the native “Translation” (Cast) feature built into the Android and MIUI ecosystem, which is based on the Google Cast and Miracast protocols, allowing you to duplicate the screen without installing additional software, which is often activated by default on Xiaomi TVs.
To start the process, unlock your smartphone and lower the notification curtain. Find the "Translation", "Smart View" icon (on Samsung) or "Screen Replay" icon. Once you click, the system will start searching for available devices within network range.
- 📱 Make sure Bluetooth on your phone is on, as it is often used for primary handshakes of devices.
- 📺 On the TV may appear a request for confirmation of the connection, which must be accepted by the remote.
- 🔄 If the device is not found, try restarting the Wi-Fi module on both gadgets.
Image quality depends on the power of the Wi-Fi signal. Using this method, the smartphone can heat up, because the video stream is encoded in real time. To view static photos or presentations, this is the ideal option, which does not require unnecessary wires.
💡
If the image twitches when connecting via Translation, close the background apps on the phone that consume Internet traffic, such as torrents or cloud downloads.
Use of Mi Remote and Xiaomi Home
For deeper integration and content management, manufacturers recommend using specialized software. Xiaomi Home or Mi Remote app allows not only to duplicate the screen, but also to manage media files stored in the phone’s memory, which is especially convenient for owners of devices based on MIUI.
After installing the app and adding the TV to the list of devices, go to the control section. There you will find the Translation button or similar functionality for transferring photos and videos from the gallery. The application interface is adapted for horizontal mode, which is convenient when using the remote.
The advantage of this method is to support a wider range of file formats that the built-in TV player may not recognize.
| Function | Built-in broadcast | Mi Home appendix | Third-party players |
|---|---|---|---|
| Stability | Medium | Tall. | Depends on the software. |
| Quality. | Up to 1080p/4K | Up to 4K. | Up to 4K HDR |
| Delay. | Low. | Medium | Minimum |
| Management | Phone from phone. | Telephone and TV | Phone from phone. |
It's worth noting that the app requires authorization in your Mi Account, which allows you to synchronize settings and quickly access smart home devices, and if you use the Xiaomi ecosystem a lot, this will become the main method.
☑️ Checking before connection
Broadcasting through YouTube and streaming services
Special attention should be paid to the “Translation” function inside the applications themselves, such as YouTube, Netflix or IVi. In this case, the phone acts only as a remote control, and the video stream is downloaded by the TV directly from the Internet, which dramatically reduces the load on the smartphone battery.
To take advantage of this opportunity, open the in-app video on your phone and click on the Chromecast built-in icon. Select your Xiaomi TV from the list. The video will play on the big screen, and you can turn the app down and do other things.
This method provides the best picture quality, because the TV decodes the stream itself using its own processor and buffering, and delays are virtually eliminated, and the resolution is automatically adapted to the screen.
⚠️ Note: To work, the TV must be logged in to the same Google account or have access to the same services as the phone.
If the stream button is not active or gray, check the app version. Also make sure that the latest version of YouTube is installed on the TV via the Google Play Store or Aptoide TV.
Wired connection via HDMI and USB-C
When wireless connection is unstable or requires maximum image quality without compression, use a cable. Modern smartphones with Type-C port require a USB-C to HDMI adapter. Make sure your phone supports MHL or DisplayPort Alt Mode technology, otherwise the image will not appear.
Connect the adapter to the phone and HDMI-Connect the adapter to the TV. Switch the signal source to the TV by pressing the Input button on the remote and selecting the appropriate port, for example, HDMI 1 HDMI 2 (ARC). The image should appear automatically.
- 🔌 Use high-quality cables of the standard HDMI 2.0 or higher for support 4K permitting.
- ⚡ Some adapters require external power, connect them to the charger.
- 📐 This method is preferred for gaming, as input lag is minimal.
The wired connection is ideal for presentations or displaying content in places with poor Wi-Fi coverage, and it ensures a stable picture without compression artifacts or interruptions.
What to do if there is no HDMI image?
Problem Solving and Lack of Image
Despite the ease of setting up, users often experience a situation where the TV can't see the phone. One common reason is to set up the firewall in the router or antivirus software that blocks local connections. Try temporarily disabling the protection to check.
Another problem is codec incompatibility: If you broadcast audio but you don't have an image (black screen), you probably can't decode the format of the video file, and then you can install a third-party player on a TV, like VLC for Android, which has built-in codecs.
It is also worth checking the date and time on both devices, and the system time desynchronization can cause security certificate errors, which can cause devices to refuse to connect to each other via a secure protocol.
⚠️ Note: When using cheap Chinese adapters HDMI You often have resolution problems. If the screen flashes or ripples, try manually setting the phone's resolution. 1920x1080 and 60 Hz.
In difficult cases, a complete reset of network settings on the phone helps, which will remove stored Wi-Fi passwords and Bluetooth settings, but often eliminates software conflicts that interfere with media transmission.
💡
The most common cause of problems is different Wi-Fi subnets (guest and main) or an outdated YouTube app on the TV.
