Xiaomi’s modern multimedia capabilities make it possible to turn a regular Samsung TV into a powerful entertainment center. Users often look for ways to bring an image from a small screen to a large panel for watching movies, photo galleries or games. Fortunately, the Android and Tizen ecosystems (Samsung’s operating system) provide several effective tools to accomplish this task without buying expensive hardware.
In this article, we will discuss in detail the wired and wireless methods of synchronization of devices. You will learn about the nuances of the Miracast protocol, the features of the configuration. DLNA-servers and specific use HDMI-Understanding the technical differences between screen duplication and media streaming will help avoid delays and sound dissynchronization.
Before you get to the specific instructions, make sure that both devices work correctly.The TV firmware and the smartphone operating system version should be relevant, since older video encoding algorithms can cause connection errors. We will look at both the regular MIUI system tools and third-party utilities for specific use cases.
Wireless connection via built-in MIUI functions
The easiest and fastest way to stream the contents of the screen is to use the built-in “Translation” feature in the MIUI shell. This method is based on Miracast technology, which is supported by most modern Samsung Smart TVs. You do not need additional cables or routers to start working, it is enough that the devices are in the same Wi-Fi range.
Activate device search on your TV. This is often called the Connection Guide or Screen Mirroring on Samsung menus, although in newer models the feature works automatically in the background. On a Xiaomi smartphone, lower the notification curtain and find the Translation (or Cast) icon. If the icon isn't there, add it through the Quick Commands Editing menu.
Once you activate the search, the phone will start scanning the available displays. Select your Samsung from the list. A connection confirmation request may appear on the TV screen — agree with it using the remote. It is critical that both devices are connected to the same Wi-Fi network (the same SSID), otherwise the search may not yield results.
There are nuances to horizontal orientation: When you start a video or game, the image on your TV can be stretched or black. To adjust the proportions, use the zoom settings on the Samsung remote (P.Size button or through the Settings menu → Image → Screen format) This allows you to fill the entire screen without distortion.
The stability of the wireless connection depends on the quality of the router's signal. If you notice a "twitch" of the picture or audio desynchronization, try to bring the router closer to the viewing zone or switch the Wi-Fi frequency to 5 GHz. The Wi-Fi Direct protocol used in direct connection is sensitive to interference from microwave ovens and Bluetooth devices.
Use of Samsung Smart View App
The official Samsung Smart View app is more advanced than the standard Miracast, which allows not only duplicate screens, but also control TVs, transfer media files and use a smartphone as a remote. For Xiaomi owners, this is one of the most stable options for integration into the ecosystem of the Korean brand.
Install an app from Google Play Market. Once launched, it will automatically scan the network for compatible Samsung TVs. Unlike system broadcasts, Smart View can encode the video stream more efficiently, which reduces the load on the smartphone battery during long-term viewing.
The app's functionality includes creating playlists and controlling playlists, so you can run a video on your phone and then send it to your TV, and keep using your smartphone for other tasks, which makes Smart View different from simple mirroring, where the phone's screen is full.
In the application settings, you can change the quality of the transmitted image. There are options from "Standard" to "High". Attention: choosing the highest quality requires a very fast Wi-Fi connection; with a weak signal, the video will be buffered.
☑️ Check before connecting Smart View
Sometimes the app requires additional permissions to access the local network. If Xiaomi can't see the TV, check the Android privacy settings. Way: Settings → Apps → Smart View → Permits. Make sure that access to Local Network and Devices Nearby is allowed.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs support the built-in Chromecast platform, which allows you to use the official Google Home app for broadcast control, which is ideal for streaming services (YouTube, Netflix) and browsers, as it provides minimal latency.
Download and install the Google Home app on your Xiaomi. Sign in to your Google account. The app will automatically detect the TV if it supports Chromecast and is connected to the same network. Click on the device icon and select Translate Screen.
The advantage of this method is versatility: you can stream the entire Chrome tab, which is useful for showing websites or content that doesn't have a "Cast" button inside the app. Image quality is usually higher than when using Miracast, thanks to optimization by Google.
⚠️ Note: When streaming through Google Home, the default sound can go through the phone's speaker. To translate the audio to the TV, tap the speaker icon in the broadcast interface and select the Samsung output device.
If you don't have a Chromecast built into your TV model, you can use a Chromecast external console or a TV Box with Android. Connection is similar: through the Google Home app, which turns any HDMI TV into a smart display compatible with Google protocols.
Connection via HDMI cable (wired method)
For tasks that require maximum stability and minimal latency (such as mobile gaming), it is best to use a wired connection. Xiaomi smartphones with a USB Type-C port often support video output via the MHL or DisplayPort Alt Mode standard.
You will need a special adapter (Hub) USB-C to HDMI. Connect the adapter to the charger of the phone and insert it into it HDMI-a cable with the second end of it going to a Samsung TV, switch the signal source to the TV to the appropriate port (e.g, HDMI 1).
MIUI automatically recognizes the external connection and switches the video output. Unlike wireless methods, there is no video stream compression, which allows for native 1080p or 4K image transmission without compression artifacts.
| Parameter | Wireless (Wi-Fi) | Wireless (HDMI) | DLNA |
|---|---|---|---|
| Delay (Latency) | High (0.5-2 sec) | Minimum (< 0.1 sec) | Medium |
| Image quality | Depends on the signal. | The Perfect (Lossless) | Original |
| Battery consumption | High-pitched | Low (charging in) | Medium. |
| Mobility | Complete. | Limited by cable length | Complete. |
It is important to consider that not all Xiaomi models support video output via USB-C. Budget series (Redmi Note, some Mi models) may have a port only for charging and transferring USB 2.0. In such cases, the HDMI adapter will not work, and you will have to rely on wireless methods.
Why can’t the HDMI adapter work?
Translation of media files via DLNA
If your goal is to watch pre-loaded movies or photo galleries, rather than duplicate the interface, DLNA technology is the best solution. It allows you to transfer media content directly from the phone’s storage to the TV decoder without loading the smartphone processor with image rendering.
On Samsung TVs, the feature is often built into the Media or Gallery menus. On the Xiaomi side, you can use the built-in Mi Video player or third-party apps like BubbleUPnP. Open the video file, click the "Cast" button, and select your TV.
The main advantage of DLNA is that you can control playback from your phone without locking the screen, so you can fold the player, you can answer a message, you can go to the menu, and the movie on the TV will continue to go. This is not possible with normal screen mirroring.
The protocol supports metadata transfers: movie covers, descriptions, and subtitles (if the container format allows), however, if the TV does not support video codec (e.g., older Samsung models and the 10-bit HEVC format), the file may not start or play without sound.
💡
For heavy transmission 4K-file DLNA Make sure that the router supports the standard 802.11ac (Wi-Fi 5) or newer, otherwise jerks may occur when playing.
Problem Solving and Lack of Image
Despite the standardization of technology, users often face a situation where Xiaomi does not see Samsung or the connection is constantly broken.The first step should always be to reboot the Wi-Fi module on both devices, sometimes completely disconnect the router from power for 10-15 seconds.
If the TV is displayed on the list but the connection is reset, check the firewall or antivirus settings on the router.Some MIUI firmware has aggressive energy savings that can "kill" the background broadcast process. Add the broadcast app to the "No Limits" list in the battery settings.
Sound problems are often solved by manually selecting the output device. Android notification curtain has an audio output switch. Also check if Do Not Disturb mode is activated on the phone, which can block system sounds of connection notifications.
⚠️ Note: If you are connected through HDMI The image is there, but there is no sound, go to the TV sound settings and make sure that the output device is selected "Receiver" HDMI» Dynamics TV" and not "Optical output».
In rare cases, network resets are required. On Xiaomi, this can be done through the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth. This will remove saved passwords, but often resolves deep driver conflicts.
💡
90% of connection problems are solved by restarting the router and checking that the phone and TV are on the same subnet (the same Wi-Fi).
