Modern multimedia capabilities allow you to turn any smartphone into a home theater control panel. Owners of Xiaomi devices often wonder how to effectively synchronize a gadget with a Samsung TV to view content on the big screen. This is not only convenient, but also significantly improves the quality of the experience of videos, games and photos.
There are many ways to implement wireless connectivity, from standard Miracast protocols to specialized applications, depending on your TV model, the version of your MIUI operating system, and the specific tasks you plan to solve. Some methods require a stable Wi-Fi network, while others work directly.
In this article, we will take a closer look at all the options available for device integration, learn about the finer points of customization, possible compatibility issues, and how to solve them, and the right configuration will allow you to enjoy content without delays and image artifacts.
Preparing devices for synchronization
Before you start setting up a broadcast, you need to make sure that both devices are ready to go.The basic requirement for most wireless methods is to have a Xiaomi smartphone and a Samsung TV on the same local network, which means they must be connected to the same router.
Check the software on both gadgets. On your TV, go to Settings menu → Support → Software Update and run the check. On your smartphone, go to Settings → About Phone → MIUI version to find system updates.
Also make sure both devices have Wi-Fi and Bluetooth modules activated. Although Wi-Fi is often the only way to transmit the video stream, Bluetooth is needed for initial device detection and pairing in some Smart View use cases.
⚠️ Warning: If your router supports dual-band (2.4GHz and 5GHz), make sure both devices are connected to the same frequency.Separating networks can cause the TV to fail to see the phone.
For stable operation, it is recommended to use a 5 GHz network if the distance to the router is small, which will provide higher channel bandwidth, which is critical for broadcasting video in 4K resolution.
Use of the built-in broadcast function in MIUI
The easiest and fastest way to display a picture from a Xiaomi smartphone screen to a Samsung TV is to use the system function Translation, which is based on the Miracast protocol, which is supported by most modern Smart TVs.
To activate, open the notification curtain control center or go to Settings → Connection and Sharing → Broadcast. The system will automatically start searching for available devices within range.
When your Samsung TV appears on the list, click on it. The TV screen may have a request for permission to connect, which must be confirmed by the remote, and then the smartphone screen is fully duplicated on the large display.
- 📱 Open the notification curtain and find the "Translation" icon".
- 📺 Choose your Samsung TV from the list.
- 🔒 Confirm the connection on the TV screen if required.
- 🎮 Enjoy the content in a horizontal mode.
It is important to note that when using this method, the smartphone screen must be unlocked, so if you lock the phone or fold the app, the broadcast may be interrupted or the image will disappear, although the sound will continue to play.
💡
To save battery power during a long broadcast, connect your Xiaomi phone to the charger, as wireless video transmission consumes a lot of energy.
Samsung SmartThings app for enhanced control
Samsung has developed its own SmartThings app, which is available on Google Play, which allows you not only to broadcast an image, but also to use the phone as a full-fledged remote control, as well as transfer files.
Install the app on your Xiaomi and log in to your Samsung Account. Once launched, the program will automatically scan the network and find a compatible TV. PIN-code displayed on the TV screen.
The app’s functionality allows you to create smart home scenarios, control volume, switch signal sources, and even use your smartphone as a touchpad to navigate the Tizen OS menu. This is especially convenient when text input using the remote seems too slow.
| Function | Description | Requirements |
|---|---|---|
| Broadcast photo | Showing slideshow from the gallery | SmartThings app |
| DU remote | Full management of the TV menu | Connecting to one Wi-Fi |
| Gamepad | Use as a gamepad | Supported games on TV |
| Sound. | Output audio to the phone | Private Mode mode |
Using the official app guarantees better compatibility and stability of the connection compared to third-party counterparts, and regular updates from Samsung fix bugs and add support for new features.
☑️ Checking before installing SmartThings
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 Google Photos without duplicating the entire screen of your smartphone.
To work with this method, the phone must have a Google Home app installed. Once the device is configured in the app, a broadcast icon (a rectangle with waves in the corner) will appear in compatible programs.
The main advantage of this method is that the phone is just a remote control, so you can fold the app, answer the phone, or go online, and the playback on the TV is not interrupted, and the quality of the picture is often higher than with Miracast.
⚠️ Note: If the broadcast icon does not appear in apps, make sure that the router settings do not include customer separation (AP Isolation, which prevents devices from seeing each other.
This method is ideal for watching online video, since the TV itself downloads the data stream, without loading the smartphone processor and without spending its battery on decoding the video.
Wired connection via HDMI and adapters
If the wireless connection is unstable or requires minimal signal delay (for example, for games), the best solution is wired connection. For modern smartphones Xiaomi with a USB Type-C port will need special adapters.
You will need a USB-C to HDMI adapter.It is important that your phone supports MHL or DisplayPort Alt Mode technology. Xiaomi flagship models typically support image output, while budget models may not have that hardware capability.
Connect the adapter to your smartphone, and connect the HDMI cable to the adapter and TV, and switch the signal source to the TV to the appropriate port (Source → HDMI 1).
- 🔌 Buy a quality adapter USB-C on HDMI supportive 4K.
- 📺 Connect the cable. HDMI TV-adapter.
- 📲 Connect the adapter to the smartphone charging port.
- ⚡ Connect the charger to the adapter to power the phone.
Using the cable also allows you to charge your smartphone at the same time, which is impossible with active wireless broadcasting, which makes the wired method indispensable for long presentations or film marathons.
Why is there no image on the cable?
Troubleshooting and troubleshooting
Users may encounter a variety of difficulties in setting up, and one of the common problems is not finding a TV in the list of available devices, first of all, check if the router is running a guest Wi-Fi mode that isolates the devices from each other.
If the broadcast is delayed or jerky, try to reduce the resolution of the output in the phone settings or bring the smartphone closer to the router. Interference from microwave ovens and neighboring Wi-Fi networks can also affect the stability of the Miracast protocol.
If there is sound and no image (or vice versa), check the audio settings in the app from which the broadcast is coming. Sometimes you need to manually switch the audio output to the speaker of the TV on the Android system.
⚠️ Note: When using third-party screencasting apps (not system-based), be careful with permissions. They may request access to personal data that is not needed for simple image transmission.
Rebooting the router often solves 90% of connection problems.Accumulated cache and routing table errors can interfere with a proper handshake between Xiaomi and Samsung.
💡
The stability of a wireless connection depends on the quality of the router and the absence of physical obstacles between it and the devices.
