Modern Xiaomi smartphones and Samsung Smart TVs have powerful functionality that allows them to be combined into a single multimedia system. Users often face the need to bring to the big screen photos from a family celebration, a presentation for colleagues or run a mobile game with more detailed graphics. Fortunately, the Android and Tizen ecosystems (Samsung’s operating system) provide several interaction scenarios that do not require complex equipment.
In this guide, we will take a look at all the current synchronization methods, from built-in system functions to specialized applications, learn how to set up a wireless connection without delay, what nuances 4K video transfer has, and what to do if devices can not see each other on the local network.
The main advantage of integration is that you don’t have to buy additional cables or adapters if your TV supports Smart TV technology. However, older models or specific tasks may require wired solutions, which will also be discussed below.
Preparing devices for synchronization
Before setting up, it is critical to ensure that the network equipment is working properly. Both Xiaomi smartphone and Samsung TV must be connected to the same Wi-Fi network. If your router is signaling at 2.4 GHz and 5 GHz with different network names, make sure that the gadgets are connected to the same range, preferably 5 GHz for better data transfer speeds.
The TV needs to activate the external signal reception mode. Depending on the year of the Samsung model, this feature can be called differently. Usually, just press the Home button on the remote, go to the Source menu and select the Screen Mirroring or Wireless Display option. On newer models with Tizen, this mode is often on by default and waits for connection.
⚠️ Note: If you use a guest Wi-Fi network or a corporate Internet with customer isolation, the devices may not see each other.
On the smartphone side, Xiaomi also needs to perform pre-checks. Make sure the version of the MIUI or HyperOS operating system is updated to the current one, as older builds may have errors in video transmission protocols. Also check if the Bluetooth module is enabled, as some initial pairing methods use it for handshake process.
☑️ Checking before connection
Use of the built-in Translation function in MIUI
The fastest way to get a third-party software is to use the system utility Broadcast. In the MIUI and HyperOS shells, this tool is deeply integrated into the system and optimized to work with the Miracast and DLNA protocols. To run, open the notification curtain and find the Translation icon (may be called Translate or Cast). If the icon is not present, add it through the shortcut editing menu at the top of the curtain.
Once activated, the feature will start searching for available displays within range of the network. When your Samsung TV appears on the list, tap its name. A request for permission to connect may appear on the TV screen — confirm it with the remote control. From now on, the image from the phone will be duplicated on a large screen with minimal latency, which is ideal for displaying an interface or photo.
💡
To reduce latency when playing games, turn off image processing modes like “Motion Plus” on your TV, as they add input lag.
It is important to note that the quality of the image depends on the power of the Wi-Fi signal. If you notice artifacts of compression or twitching, try to get closer to the router. Xiaomi system broadcast can automatically bitrate depending on the quality of the communication channel, but a stable 5 GHz signal is always preferable.
Broadcasting through Samsung Smart View
If standard Android tools are not working well, the best solution is to use a proprietary app from the TV manufacturer. Samsung Smart View (or simply SmartThings on newer versions of Android) provides a more reliable connection and offers advanced settings. Download the app from Google Play Market and install it on your Xiaomi.
Once the app is running, it scans the network and suggests adding a new device. Select your TV from a list. Unlike the system broadcast, here you have access not only to duplicate the screen, but also to manage media files. You can select a specific video or photo from the phone gallery and send it to TV, while continuing to use the smartphone for other tasks.
| Function | System broadcasting | Smart View / SmartThings |
|---|---|---|
| Screen duplication | There is. | There is. |
| Media management | Limited. | Complete. |
| Working in the background | No (screen on fire) | Yeah (can roll) |
| Stability | Medium | Tall. |
The app is especially useful if you’re planning a content demo, as it allows you to block your phone screen or use other apps without interrupting the stream on your TV. This makes Smart View an indispensable tool for watching movies from local storage.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs support the built-in Google Cast protocol (Chromecast built-in), which allows you to stream content directly from apps like YouTube, Netflix or Google Photos without duplicating the entire screen of your smartphone.
The way it works here is different from Miracast, where the phone acts as a remote, only giving the TV a link to the video stream that the TV downloads itself, which significantly unloads the smartphone processor and saves battery life, and the image quality is often higher, because the TV decodes the video itself using its own codecs.
⚠️ Attention: Google Home's "Cast screen" feature duplicates the entire Android interface, including notifications and system sounds. Make sure the sound on the phone is not at its maximum to avoid echoes.
To start, open Google Home, find your TV in the list of devices, and click on Translate screen. If an app like YouTube has a Chromecast icon, click on it and select TV. This is the most convenient way to stream a video, as it provides the best picture quality and no management delays.
Wired connection via USB-C to HDMI
In situations where Wi-Fi is overloaded or absent, the only reliable option is a wired connection. For this, your Xiaomi smartphone needs support for video output technology via a USB port. Note: not all Xiaomi models support video output via USB-C. Flagship series (Mi, Mix, some models of Redmi Note Pro) usually have this feature implemented through the DisplayPort Alt Mode standard.
You will need a special adapter. USB-C to HDMI. Connect the adapter to the phone and HDMI-Connect the adapter and the TV. Switch the signal source to the TV. TV port-to-port HDMI. If the phone screen goes out or writes "signal not supported", your specific port is likely USB Can't transmit video, only data and charge.
Video support check:
1. Go to Settings → About the phone.
2. Find the CPU specification (Snapdragon 8xx series is usually supported).
3. search the web for the search "[Phone Model] HDMI output support".The advantage of the wired method is that there is no delay (input lag) and maximum image quality without compression, which is an ideal choice for gamers who want to play mobile shooters on the big screen, or for presentations in a bad Internet environment.

Problem Solving and Lack of Image
Even when you set it up properly, there can be conflicts. One of the common problems is that you have a black screen when you try to run secure content (DRM). If you're trying to stream a movie from a paid online movie theater, and you see a black image with sound, that's copy protection, and that's where the built-in Cast function inside the player app itself, not screen duplication, will help.
Users also often complain about audio and video desynchronization, which is treated by rebooting the router and clearing the Translation app cache on the phone. Go to Settings → Apps → All Apps → Broadcast → Clear cache. Sometimes it helps to temporarily shut down a VPN on a smartphone, as virtual networks can change the traffic route and block local device detection.
If a Samsung TV doesn't see the phone at all, try resetting the network settings on both devices. On the TV, this is done via Settings → General → Network → Network Reset. On the phone, you can use the Network Reset feature (not a full phone reset!), which will return the Wi-Fi and Bluetooth settings to factory values by removing saved passwords.
💡
90% of connection problems are solved by restarting the router or switching phones to 5GHz Wi-Fi range.
