Modern technology allows you to turn your Xiaomi smartphone into a powerful multimedia center, easily broadcasting content to the big screen. Owners of Samsung TVs with Smart TV feature often wonder how to bring the image from their device to the panel without unnecessary wires. Fortunately, the Android ecosystem and Tizen (Samsung operating system) are great friends, providing several ways to connect.
In this article, we will take a look at all available synchronization methods, from the standard Miracast wireless protocol to wired HDMI connectivity, and learn what settings you need to activate on both devices to ensure stable high-resolution signal transmission, and we will also touch on the nuances of working with different versions of MIUI and Android firmware.
Whether you want to show your friends pictures from your vacation or run a movie in 4K quality, the right way to connect will play a key role. For wireless video transmission in 4K resolution, be sure to use a 5GHz Wi-Fi network, since 2.4GHz may not be able to pull the bitrate. Let's look at the tools you already have at your fingertips.
Preparing devices for synchronization
Before you start directly pairing, you need to make sure that both devices are in the right state. The basic requirement for most wireless methods is to find a Xiaomi smartphone and a Samsung TV on the same local Wi-Fi network. If the router distributes networks at 2.4 and 5 GHz with different names, connect the gadgets to one of them, preferably 5 GHz for speed.
Check the software’s relevance. On your TV, go to the settings menu and find the system update section. On your Xiaomi smartphone, you should also check for updates in Settings → About Phone → MIUI version. Outdated Wi-Fi module drivers can cause unstable connection or complete device failure.
☑️ Connection readiness
Importantly, Samsung’s Smart View feature may not be activated by default on some models, so you’ll need to go to the general settings and make sure that the external device detection option is allowed, a basic step that many users ignore when they encounter visibility issues.
⚠️ Note: If your router has a function"AP Isolation, devices won't see each other even on the same network.
Wireless connection via built-in broadcast function
The simplest and most common way is to use the native Android feature, which is called Translation or Caste in the MIUI shell, which is based on the Miracast protocol that supports most modern Samsung TVs. You don't need to install third-party apps to get started, everything is already built into the system.
Open the curtain control panel on your Xiaomi smartphone. Find the Translation icon (may be called Transcript, Wireless Monitor or Cast). If the icon is not available quickly, click on a pencil or three menu editing dots and add it. Once activated, the phone will start searching for available devices on the network.
A Samsung TV screen may have a request for permission to connect. Use the remote, press the Home or Source button, select the Screen Mirroring signal source, or simply confirm the request for a pop-up. The image from the phone will appear on the large screen with minimal latency.
What to do if your phone can’t see TV?
The quality of the image depends on the signal strength. If you notice the sound and video are out of sync, try to zoom in on the router or the phone. Miracast's protocol is sensitive to interference, especially in apartment buildings where the air is clogged with neighborhood networks.
Use of Samsung Smart View App
While the streaming feature is built into Android, Samsung's proprietary Smart View app (now often integrated into the system or replaced with SmartThings) offers deeper control.For Xiaomi phones, the SmartThings app available on Google Play is best used.It lets you not only duplicate the screen, but also use the phone as a remote.
Install SmartThings from the Play Market. Once launched, the app will ask you to register for a Samsung account if you don't have one. This is necessary to sync your devices into a single ecosystem. Once logged in, click the add-on button and select your TV from the list of found ones.
Unlike standard broadcasting, you can control media playback more flexibly, like running a video from a gallery and sending it to TV while still using the phone for other tasks. In standard Miracast mode, the phone's screen is often locked or requires constant active use.
| Function | Broadcast (Miracast) | SmartThings |
|---|---|---|
| Type of connection | Systemic | Annex |
| Use of the telephone | The screen is duplicated | You can use it as a remote. |
| Stability | Depends on Wi-Fi. | Tall. |
| 4K support | Yeah (depends on router) | Yes. |
💡
SmartThings is ideal for managing the media library, whereas system broadcasting is better for gaming and showing the application interface.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs support the built-in Chromecast built-in protocol, which allows you to stream content directly from apps like YouTube, Netflix or Yandex.Cinema without loading on the phone's processor.
Download and install Google Home on your Xiaomi. Open the app and find your TV on the device list. Click on the TV icon and select Translate screen. This method often works better than standard Miracast, because it uses different video stream compression algorithms.
The main advantage of this method is that you can control the stream from any device on the network, you can run a movie on a tablet, and then switch control to a Xiaomi phone, and there is lower latency, which is critical if you want to show dynamic content.
Keep in mind that Chromecast requires a Google account to work. Make sure you are logged in to the same account in the Google Home app that is used in the Chrome browser or on other Android devices.
Connecting via HDMI adapter
Wireless technology is convenient, but it doesn't always provide the perfect quality, especially in noisy air conditions. If you want maximum stability and no delays, for example, for games or presentations, use a wired connection. This will require a USB-C to HDMI adapter.
Connect the adapter to the charging port of the Xiaomi phone, and at the other end insert an HDMI cable going to the Samsung TV. switch the signal source on the TV to the appropriate HDMI 1 or HDMI 2 port. The phone automatically determines the external display and begins signal transmission.
Important: Not all Xiaomi models support video output via USB-C. This feature (MHL or DisplayPort Alt Mode) is usually available in the flagship models of the Mi and Xiaomi series (digital series), as well as in some Redmi Note Pro models. Budget models may not transmit the image, limited to charging only.
⚠️ Note: When wired, the phone can run out quickly if the adapter does not have an additional power port. Use an adapter with the ability to connect the charger.
The advantage of the cable is that it doesn't compress artifacts or lags, and it's transmitted in original quality, which is especially noticeable on large diagonals on Samsung TVs, and it's the only way to get 100% lossless image quality.
Solving and resolving problems
Even with the right setup, there may be crashes. A common problem is that the phone sees the network but doesn't see the TV. In this case, try temporarily disabling the antivirus or firewall on the router if you have any, and resetting the network settings on the phone through the Settings menu → Connection and Sharing → Wi-Fi resetting also helps.
If the image twitches or is low resolution, check the load on the Wi-Fi channel. Downloading files on other devices can "clog" the channel. Try to switch the router to a less loaded channel in the 5 GHz band through the admin panel (usually 192.168.0.1 or 192.168.1.1).
In some cases, cleaning the cache of the Google Play Services service on a Xiaomi phone helps. Go to Settings → Apps → All apps → Google Play Services → Memory → Clean. This often solves the problems with detecting devices through Google protocols.
💡
Rebooting the router solves 80% of the connection problems: turn it off for 10 seconds, then turn it back on and wait for the network to fully load.
Comparison of connection methods
The choice of method depends on your goals. You can use the built-in stream to view photos and videos from the gallery, SmartThings to manage your smart home and media, only cable or 5GHz Wi-Fi to play, and understanding the differences will help you avoid frustration.
Remember that software is constantly updated. Features that are not available today may come tomorrow. Keep an eye out for MIUI and Tizen firmware updates to keep up with new integration opportunities.
