The modern smart home ecosystem is often made up of devices from different manufacturers, and the bundle of Samsung’s smartphone with Xiaomi Mi TV is one of the most popular combinations on the market. Users often face the need to stream content from a mobile device to a large display, whether it’s watching movies, gallery photos or even mobile games. Fortunately, wireless data protocols have become so versatile that the device’s brand has ceased to be a critical barrier.
The main standard that screen broadcasting relies on in this case is Miracast technology (often labeled as Wireless Display). Xiaomi TVs running on Android TV or proprietary PatchWall have built-in modules for receiving the signal, and Samsung smartphones are equipped with Smart View. This means that for most use cases you will not need additional cables or complex adapters.
However, despite the stated compatibility, the setup process can have its own nuances, depending on the version of the software and the router model. In some cases, automatic device detection does not work the first time, requiring manual network setup or resetting. Next, we will discuss in detail all available methods of connection, from standard tools to third-party applications.
Device preparation and Wi-Fi network verification
The foundation of a stable connection is the right organization of the local network. The most important requirement is that both devices must be on the same subnet. This means that a Samsung smartphone and a Xiaomi TV must be connected to the same router. If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, make sure that both gadgets are connected to the same frequency, although modern routers often combine them into the same network with a single name.
Check the software’s relevance on both devices. On Xiaomi TV, you can do this through the settings menu by selecting Settings → About TV → System Update. For a Samsung smartphone, the path usually looks like Settings → Software Update → Download and Install. Outdated Wi-Fi module drivers may not properly handle handshake protocols between devices from different vendors.
⚠️ Note: Guest Network often blocks devices from being discovered by each other for security reasons. If you can't find a TV on the list of available devices, check if you're in the guest segment.
While Wi-Fi Direct allows you to transmit data over sufficient distances, thick walls or powerful sources of interference (microwave ovens, neighbor routers on the same channel) can significantly reduce channel bandwidth. For high-resolution (4K or high-bitrate Full HD) video, it is desirable that the devices are in line of sight or in the next room.
Broadcasting through the built-in Smart View feature
The fastest and most native way to display an image is to use Smart View technology, which is built into Samsung’s One UI shell, which is based on the Miracast standard and allows you to duplicate your smartphone screen on your TV in real time with minimal latency.
To activate the mode, lower the notification curtain on your Samsung smartphone with a double swipe down. In the Quick Settings panel, find the Smart View icon. If it's not on the first screen, flip to the right. Once you click, the system will start looking for available devices within range. Your Xiaomi TV should appear on the list (often signed as Android or a TV model, such as MI TV 4S).
- 📱 Click on the Smart View icon in the notification curtain.
- 📺 Wait for the name of your Xiaomi TV to appear on the list.
- 🔗 Tap the name of the device to start pairing.
- ✅ Confirm the connection on the TV screen if you receive a request.
Once the connection is successful, the smartphone image will appear on the TV, and it's important to understand that in this mode, the phone works as the main processor rendering the picture, and the TV acts only as a monitor, so the brightness of the smartphone screen can affect power consumption, and active notifications will be visible on the large screen.
☑️ Check before connecting Smart View
Using Google Chromecast built-in technology
Xiaomi TVs often have built-in support for Google Cast (Chromecast) technology.This is an alternative method that works differently than Miracast. Instead of completely duplicating the screen, the smartphone sends the TV a link to the content, and the TV loads it itself, which reduces the load on the phone's battery and allows it to be used for other tasks while watching.
To work with this method, make sure that your smartphone has Google Home (for initial setup if it wasn’t done) and the current version of Google Play Services. In apps that support broadcasting (YouTube, Netflix, Spotify, Chrome browser), look for the characteristic icon of the rectangle with waves in the corner.
If you use Google Chrome on a Samsung smartphone, you can stream the entire tab. Open the browser menu (three dots in the corner), select Broadcast... (Cast) The system will suggest you choose a device. Unlike Smart View, here the picture quality often stabilizes faster, as the TV uses its decoders.
Why does Chromecast not work?
Connecting through third-party applications (Mi Remote and others)
If standard methods do not give the desired result or require advanced management functions, third-party applications come to the rescue. Xiaomi’s official Mi Remote app is primarily designed to control the TV as a remote, but in some versions and regions it offers media file transfer functions.
One of the most popular apps is Web Video Caster or LocalCast, which allows you to stream not only online videos, but also files stored in the memory of a Samsung smartphone. The algorithm is simple: you install the app on your phone, and on the Xiaomi TV (via the Google Play Store on TV) install a Receiver of the same application if you need it.
| Annex | Type of transmission | Support for formats | Advertising |
|---|---|---|---|
| Smart View (staff) | Mircasting (screen to screen) | All screen formats | No. |
| Google Home | Cast (flow) | Video, audio, photo | No. |
| Web Video Caster | Stream + Local Files | MKV, AVI, MP4, Web pages | Available (in the free version) |
| AirScreen (on TV) | AirPlay/Miracast receiver | Universal. | Depends on the version. |
When using third-party software, it is important to pay attention to the permissions you give the application. To work correctly, the program needs access to the local network and, in the case of mirroring, permission to write the screen. Without these rights, data transfer will be impossible or interrupted immediately after start.
Wired connection via USB-C to HDMI adapter
Wireless technology is convenient, but not always stable. If you want maximum image quality without compression and delays (for example, for games), the best solution is wired connection. Samsung Galaxy S series smartphones (starting with the S8) and Note support video output via USB Type-C port thanks to DisplayPort Alt Mode technology.
To implement this method, you will need a special USB-C to HDMI adapter. One end of the adapter connects to the smartphone, and the other connects an HDMI cable that goes to the Xiaomi TV. The TV in this case acts as a regular monitor, so you need to switch the source of the signal (Source) to the appropriate HDMI port on the remote.
⚠️ Not all Samsung smartphones support video output via USB. Budget models of series A (e.g, A10, A20, A30) This is often a problem, even if the port USB-C In such cases, the image will not appear on the TV, and wireless methods will be required.
The advantage of the wired method is that it does not depend on Wi-Fi speed and ether load. The picture is transmitted in native resolution, and the sound is digitally lossless. In addition, the smartphone in this mode can continue to charge if the adapter has an additional power port (PD - Power Delivery).
💡
For high-dynamic games, use only a wired HDMI connection, as even the best 5GHz Wi-Fi can give micro-latency (input lag) noticeable in shooters and fighting games.
Solution: TV can't see the phone
One of the most common problems is when a Samsung smartphone simply doesn’t detect a Xiaomi TV in the list of available devices.This can be caused by settings on the router’s firewall, which isolates customers from each other (AP Isolation. Go to the router settings and make sure the function is AP Isolation or Client Isolation is disabled.
Another reason is caching. DNS Or errors in network services. Try to do a complete reboot of the chain: turn off the router, the TV and the smartphone. Turn on the router and wait for the network to load fully. Then turn on the TV, let it connect to Wi-Fi, and only then turn on the smartphone. This sequence helps to correctly register devices in the table ARP router.
If the problem persists, check the date and time settings. Both devices must have the current date and time set, preferably automatically over the network. Time out-of-synchronization can lead to security certificate errors when trying to establish a secure WPA2/WPA3 connection.
💡
90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
