Modern Xiaomi smartphones and Samsung smart TVs are powerful multimedia entertainment bundles, but users often find it difficult to pair them. Device integration allows you to display photos, videos and even the screen of a mobile gadget on a large display, turning the living room into a home theater. There are several proven methods, each of which has its advantages depending on your needs and equipment model.
The main task when connecting is to provide a stable data channel, whether it is a wireless network or a physical connection. Wireless technologies are convenient for fast display of content, while wired solutions guarantee the maximum image quality without delay. In this article, we will discuss all the current methods in detail so that you can choose the most suitable option for your situation.
Before you start setting up, you need to make sure that both devices are working and have up-to-date software versions. Compatibility of data protocols plays a key role: older models may not support the latest standards for encoding video stream. Proper preparation will eliminate most common connection errors and save you time.
Use of Screen Mirroring (Smart View)
The most common and fastest way to stream a Xiaomi phone screen to a Samsung TV is by using Screen Mirroring technology, known in the Samsung ecosystem as Smart View.This method is based on the Miracast standard, which allows you to transmit video directly, without using a router, if the devices are on the same network or support Wi-Fi Direct. To start, you do not need to install additional applications, since the feature is built into the MIUI shell.
To activate the broadcast, lower the notification curtain on your smartphone and look for the "Translation" or "Cast" icon. In some versions of the firmware, it may be called "Wireless Monitor." Once you press it, the phone will start searching for available devices within range. Make sure the TV in the Source menu selects Screen Mirroring or Mobile to TV mode to be searchable.
Once your Samsung TV appears on the list on your smartphone screen, click on it to pair. The TV screen may have a request for confirmation of connection, which must be received by the remote control. Signal latency with this method is minimal, allowing you to comfortably view videos and photos, but for dynamic games it can be noticeable.
⚠️ Note: If the phone can't see the TV, make sure both devices are connected to the same Wi-Fi network (2.4GHz or 5GHz.
Connecting through Samsung SmartThings app
The official Samsung SmartThings app is a universal tool to manage the entire ecosystem of the Korean brand’s smart home. By installing this software on your Xiaomi from the Google Play Market, you get advanced control of your TV, including mirror display and transfer of media files. The application requires authorization through a Samsung Account, which ensures the security of the connection.
The setup process starts with adding a new device. Press the + button in the app, select the type of TV device and wait for the system to detect your TV. Once the code displayed on the TV screen is confirmed, the smartphone and the TV will be linked. The application interface has a Smart View feature that duplicates the contents of the mobile display on the large screen.
The advantage of using SmartThings is the ability to not just duplicate the screen, but use the phone as a remote or transfer specific files from the gallery in the background without blocking the smartphone. However, the stable operation of the application requires a constant active Internet connection and enabled Bluetooth for initial detection.
☑️ Checking before connection
Importantly, on some Xiaomi models with aggressive battery optimization, the app can close in the background. To avoid this, go to the battery settings and set SmartThings to “No Limits” mode, which guarantees continuous data transfer.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs support built-in Chromecast technology, which allows you to use standard Android operating system tools. For this method, you will need the Google Home app, which is the control center of the smart home from Google. This method often works more stable than the native Miracast, especially when streaming videos from online services.
Open the Google Home app on your Xiaomi and find your TV in the list of devices. Click on the TV icon and then select the "Cast my screen" button. The system will warn you that the sound and image from the phone will be broadcast to the TV. Confirm the action, and in a few seconds the image will appear on the big screen.
The main advantage of this method is the ability to stream content from applications that do not have their own “Cast” button, such as a browser or third-party video players, the image quality automatically adjusts to the connection speed, minimizing buffering, but it is worth considering that the resolution can dynamically change depending on the load on the network.
Why is it that Google Home broadcasting is interrupted?
Using DLNA to play back a media library
If your goal is not to duplicate the screen, but to watch movies or listen to music stored in the phone’s memory, the best solution is DLNA technology. Unlike Miracast, DLNA only transmits the media file itself, which the TV takes over, which frees up the resources of the smartphone and allows it to be used for other tasks while watching.
To implement this method, Xiaomi can use the built-in Mi Video video player or third-party apps such as BubbleUPnP or VLC. Open the video file in the player, click the "Cast" button (usually looks like a rectangle with waves) and select your Samsung TV from the list of devices.
The key advantage of DLNA is that it supports subtitles and can control playback (pause, rewind) directly from the phone. In addition, this method is less demanding on the power of the Wi-Fi network, since it does not transmit real-time video stream, only the file data. However, the file format must be supported by the TV codecs, otherwise playback will be impossible.
| Connection method | Delay (Latency) | Image quality | Battery consumption |
|---|---|---|---|
| Screen Mirroring (Miracast) | Low. | High (depending on the signal) | High-pitched |
| Samsung SmartThings | Medium | High. | Medium. |
| Google Home (Chromecast) | Low. | Optimal. | Medium. |
| DLNA (Media Only) | Absent. | Original file | Low. |
Wired connection via HDMI and adapter
For users who are critically interested in connection stability and no delays, such as when presenting or playing, a wired connection is the best choice. Since Xiaomi smartphones do not have a native HDMI port, you will need a special USB-C to HDMI adapter. It is important to make sure that your phone supports the MHL standard or DisplayPort Alt Mode, otherwise video transmission will not work.
Connect the adapter to the phone's charging connector, and the adapter to the HDMI cable that goes to the TV. Switch the signal source on the TV to the appropriate HDMI port. The image should appear automatically. Unlike wireless methods, here you get a signal in full resolution of 1080p or even 4K without compression.
The disadvantage of the method is the presence of wires that can limit mobility, as well as additional battery consumption, since the adapter is powered by the phone. It is recommended to use adapters with an additional port for charging, so that the phone does not run out during a long session.
💡
When buying a USB-C to HDMI adapter for Xiaomi, pay attention to HDCP 2.2 support if you plan to watch protected content (Netflix, Disney+) in 4K. Cheap adapters without this support will show a black screen.
⚠️ Note: Not all Xiaomi models support video output via USB-C. Budget series (Redmi, some Mi models) often lack this feature at the hardware level.
Solving Connection Problems and Errors
Even with the right setup, there can be situations where the phone and the TV refuse to be friends. One of the common problems is that you can't find the device, in which case you can try rebooting the router, because the multicast traffic needed to detect the devices is sometimes blocked during long-term hardware operation.
Another common mistake is to desynchronize sound and image, which is often treated by changing the audio codec settings in the phone's engineering menu or updating the TV's firmware, and it's also worth checking if the TV is running Game or PC mode, which can change how the video is processed.
If none of the wireless methods are stable, check the firewall settings on the router. Sometimes security features block local interaction between devices. In extreme cases, resetting network settings on a Xiaomi phone (Settings → Connection and Sharing → Wi-Fi Reset) helps eliminate software conflicts.
💡
The stability of the wireless connection depends on the quality of the router. For broadcasting 4K video, it is recommended to use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX) standard.
