Integrating Xiaomi’s smartphone into the Samsung Smart TV home theater ecosystem offers access to enhanced multimedia capabilities. Users often look for ways to stream photos, videos or desktops to the big screen for more comfortable viewing. Current technology allows for this in several ways, from wireless protocols to a classic wired connection.
The synchronization process depends on the version of the MIUI or HyperOS operating system, as well as the year of release of the TV. Device owners face the need to choose the optimal method that will ensure stable signal transmission without delay. Below we will discuss detailed algorithms for actions for various use cases.
The main challenge is to ensure that both devices are in a single digital environment or physically connect their ports. It is critical that the router supports the 5 GHz standard for wirelessly transmitting high-resolution video without artifacts and buffering, and ignoring this requirement can lead to sound and image dissynchronization.
Preparation of devices for pairing
Before you start setting up, make sure both devices are ready to communicate, a basic step that is often missed, leading to errors in finding devices online. Check that Samsung TV has activated Smart View or a similar signal reception service.
On a Xiaomi smartphone, you should update your system software to the latest available version. The screen settings often hide additional projection options that you need to manually activate. Also make sure the Wi-Fi module is working correctly.
For stable operation, it is recommended to restart the router if it has been working without interruption for a long time. This will clear the cache of network spreadsheets and highlight new ones. IP-Static addresses can sometimes conflict with detection protocols. DLNA.
- 📱 Make sure that your Xiaomi phone has Bluetooth and Wi-Fi enabled.
- 📺 On Samsung TV, go to the source menu and select Screen Mirroring.
- 📶 Check that both devices are connected to the same Wi-Fi network (the same). SSID).
- 🔋 Charge your smartphone to at least 40%, as the screen broadcast consumes a lot of battery.
⚠️ Note: If your router has a Guest Network feature, don't connect your broadcast devices to it. Guest isolation prohibits interaction between gadgets within the network.
After you have done your pre-checks, you can move on to the direct choice of the connection method, and there are three main ways, each of which has its own advantages depending on your goals.
Broadcasting through the built-in function "Translation"
The fastest way to display an image is to use the native feature of the Android system, which is called Translation in the MIUI shell, which is based on the Miracast protocol and does not require the installation of additional software.
To start the process, lower the notification curtain and find the Translation icon. If it is not available quickly, go to Settings → Connection and Sharing → Broadcast. The system will start searching for available displays in range.
When your Samsung TV appears on the list, click on it. You may see a request for permission to connect on your TV screen, which you need to confirm with the remote, and then the smartphone screen will be completely duplicated on the TV.
The quality of the transmission depends on the power of the Wi-Fi signal. Using this method, the phone turns into a video stream transmitter, so it can heat up. The Miracast protocol creates a direct connection, bypassing the Internet channel, but loading the local network.
- 🎮 Perfect for presentations or photo albums.
- 📉 Not suitable for fast paced games due to possible input delay (input lag).
- 🔋 The smartphone screen should be turned on, which increases power consumption.
💡
If the broadcast is interrupted, try temporarily disabling the VPN on your smartphone.VPN encryption protocols often block local device detection.
Use of Samsung Smart View App
An alternative and often more stable option is to use the official Samsung Smart View app, which was originally created for Samsung devices, but many features are available for other Android smartphones, including Xiaomi.
Download the app from the Google Play Store or use the built-in SmartThings service, which is pre-installed on many new Xiaomi models. Once launched, the app will scan the network and suggest you connect to the TV.
The main advantage of this method is that you can use the phone as a remote control, so you can not only stream content, but also adjust volume, change channels or control the playback of media files.
| Function | Broadcast (Miracast) | Smart View / SmartThings | HDMI Cable |
|---|---|---|---|
| Delay (Latency) | Medium (50-100 ms) | Low (depends on router) | Missing (0 ms) |
| Image quality | It's shrinking. | High. | Maximum (4K HDR) |
| Battery consumption | High-pitched | Medium. | Charging the phone |
| TV administration | No. | Complete. | No. |
You can choose to use Screen Translation mode in the app or simply send a specific file from the gallery, and the second option is less resource-intensive, since the phone doesn't render the entire interface, it only sends a stream of video.
What to do if the app can’t see the TV?
Connection via HDMI (Type-C to HDMI) cable
For users who want maximum image quality and no delays, wired connectivity is the best solution, the only way to get honest 4K at 60Hz without compression.
You'll need a USB Type-C to HDMI adapter. It's important to check if your specific USB port on Xiaomi phone supports video output. Not all USB 2.0 ports can transmit video, often requiring support for the DisplayPort Alt Mode standard.
Video support check:
1. Go to Settings → About the phone.
2. Find the specification of the USB port.
3.Look for the mention of USB 3.1 or USB 3.2 Gen 1/2.Connect the adapter to your smartphone and insert the HDMI cable into your TV. Switch the TV signal source to the appropriate port (e.g. HDMI 1) and the image should appear automatically.
⚠️ Note: When connected via cable, the phone may not charge if the adapter does not have an additional power port.Use pass-through charging adapters.
This method turns your smartphone into a full-fledged media center, so you can play games, work with documents, or watch movies while your phone is on the table, and a wired connection ensures that your Wi-Fi neighbors don't eat the entire channel.
- 🎬 The best choice for watching movies in high bitrate.
- 🎮 The only option for a comfortable game of cloud gaming.
- 🔌 Requires the purchase of additional equipment (adapter).
Broadcasting through Chromecast built-in
Many modern Samsung TVs support Google Cast (Chromecast built-in) technology, which allows you to stream content from apps directly without loading the phone’s processor with a desktop display.
Open an app like YouTube, Netflix or Chrome on Xiaomi. Find a broadcast icon (a rectangle with Wi-Fi waves). Select your TV from the list.
The phone is only a remote control, and the video is buffered directly from the Internet by the TV itself, so the quality is independent of the speed of the Wi-Fi between the router and the phone once playback has started.
☑️ Checking readiness for Chromecast
The advantage of this method is that you can turn off the app or even turn off the phone screen, and the playback on the TV will not be interrupted. This saves battery power and allows you to use the smartphone for other tasks.
Set up Mi Remote for management
If your goal is not to broadcast the screen, but to control the TV with your smartphone, use the Mi Remote app, which is pre-installed on all Xiaomi and Redmi devices.
Launch the app and press "Add device." Select "TV" and "Samsung" brand. Follow the instructions on the screen by pressing the buttons to check the TV's response.
Once paired successfully, your phone will replace the physical remote, which is especially useful if your native remote is lost or depleted, and the app emulates an IR port (if you have one on your phone) or uses Wi-Fi Direct.
💡
The Mi Remote app works even without internet if the phone has an infrared port, as it uses infrared radiation rather than a radio channel.
The app's functionality allows you not only to switch channels, but also to type text from the phone's keyboard, which is much more convenient when searching for YouTube videos on your TV.
Solving problems and mistakes
Despite the ease of setting up, users may encounter difficulties, and a common problem is that the phone can't see the TV, in which case, check to see if the antivirus or firewall is blocking the local network.
Another common mistake is to desynchronize audio and video, which can be treated by changing the codec settings in the engineering menu or simply restarting the router, and also try to reduce the quality of the stream in the source application.
If the image is twitching or low resolution, check the screen resolution settings in the Translation menu. Sometimes you should manually set 1080p instead of Auto to stabilize the flow.
