Owning a modern ecosystem means not only having a Xiaomi smartphone, but also having a large screen to view content comfortably. Often you need to show photos, run a video, or even play a mobile game on a large Samsung display. Fortunately, wireless data technologies allow you to do this in seconds without unnecessary wires.
However, despite its apparent simplicity, users often face problems synchronizing devices from different manufacturers, data protocols may differ, and security settings may block the connection, and in this article we will discuss in detail all current methods, from built-in MIUI functions to specialized applications.
You don't need complex hardware to get started, just have both devices on the same LAN or support direct connectivity, and we'll look at both software and hardware for all TV models.
Use of Mi Drop and Screen Mirroring
The easiest way is to use native capabilities of the MIUI or HyperOS operating system. In Xiaomi smartphones, this feature is often called “Translation” or “Wireless Monitor”. Samsung TVs, in turn, support the Miracast standard, which ensures compatibility at a basic level.
To start broadcasting, lower the notification curtain on your phone and find the Translation icon. If it's not available quickly, go to settings, select Connect and Share, and activate the feature. The phone will start searching for available devices within Wi-Fi range.
On a Samsung TV, you need to run the Source app and select Screen Mirroring or Screen Translation mode, which is automatically activated when a connection request is made.
⚠️ Warning: When you first connect to your TV, you may receive a request for permission to access. Be sure to click "Accept" on the remote, otherwise the connection will be reset in 30 seconds.
The quality of the image depends on the power of your router. If you notice a latency or a “teared” image, try to bring the phone closer to the router or switch it to 5 GHz.
Setup via Samsung SmartThings app
If the standard Miracast protocol is unstable, the best solution is to use the official utility from the TV manufacturer. Samsung SmartThings app turns the smartphone into a remote control and allows you to display media files with high stability.
To get started, download the app from Google Play and run it. The program will automatically scan the network for compatible devices. You will need to log in to your Samsung Account, which is a requirement for full functionality.
- 📱 Install SmartThings app on Xiaomi smartphone and log in.
- 📺 Make sure the TV is on and connected to the same Wi-Fi network as the phone.
- 🔗 Click the Add Device button in the app and select your TV from the list.
- 🎬 To display the screen, use the “Translation of the phone screen” function in the app menu.
This solution is particularly useful for controlling video playback, so you can browse through social media while the movie is on the TV, and the Smart View feature inside the app allows you to zoom in and select the aspect ratio.
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs have built-in support for Chromecast technology, which allows you to stream content directly from apps such as YouTube, Netflix or Google Chrome browser, bypassing system restrictions.
To work with this method, the phone must have a Google Home app installed. Once installed, open the program, find your TV in the list of devices, and click on Translate Screen. The system will create a stable connection with minimal latency.
The advantage of this method is that it uses Google servers for buffering, which reduces the load on the local network, and if the router is weak, this method can work even better than direct Miracast.
Why does the sound disappear during broadcast?
Connection through HDMI-cable
When wireless connectivity is impossible or maximum quality is required without compression, the only option is cable connection. However, simply plugging a USB-C cable into HDMI will not work, because Xiaomi smartphones require video output support.
You’ll need a dedicated USB-C to HDMI adapter that supports the MHL or Alt Mode standard. It’s important to check your phone’s specifications: budget models often don’t have a video output via a charging port, while Mi and Xiaomi Pro flagships typically support this feature.
The procedure is simple: connect the adapter to the phone, insert it into it. HDMI-The cable, and the second end to the free port of the TV. HDMI 1 HDMI 2.
| Adapter type | Xiaomi support | Image quality | Do I need Wi-Fi? |
|---|---|---|---|
| USB-C to HDMI (MHL) | Only flagships. | 1080p / 4K | No. |
| Wireless dongle | All models. | Depends on the network. | Yeah (Wi-Fi Direct) |
| Smart View (App) | All models. | Up to 1080p. | Yes. |
When wired, the phone may not charge because the port is busy transmitting video, and expensive docking stations with additional power input will be required to charge and broadcast simultaneously.
☑️ Checking before buying the cable
Using DLNA to play media files
If your goal is not to duplicate the screen, but to simply view photos or videos stored in the phone's memory, then DLNA technology is perfect. It allows the TV to see the phone as a network storage.
On Samsung TVs, this feature is often built into a media player, you just have to open the Media or Gallery app on TV, select the source of the Phone, and wait for the files to appear. On Xiaomi's side, you may need permission to access media files.
For more advanced management, you can use third-party controller apps like BubbleUPnP or LocalCast, which allow you to create play queues and manage subtitles, which is critical for watching movies.
⚠️ Note: Video file formats should be supported by TV codecs. If the file is not played, try converting it to your computer or using a third-party player on TV, for example, VLC.
Solving Connection and Delay Problems
Even with the right setup, there can be failures, and most often the problem is router settings, so if devices are on different subnets or if AP Isolation is enabled, they just won't see each other.
Try rebooting your router by resetting your network cache, and it's also worth checking if the router has a speed limit for certain devices. IP-TV addresses in router settings.
If the image twitches, reduce the output resolution in the broadcast settings. Instead of 4K, choose 1080p, which will significantly reduce the data flow and stabilize the picture. Also close the background applications on the phone that consume traffic.
💡
For low latency games, use wired connectivity or Wi-Fi 6 technology. Wireless methods always have an input lag, which can interfere with dynamic shooters.
In rare cases, the cause is an antivirus or firewall on your smartphone. Try temporarily disabling the network protection and checking the connection. If the problem disappears, add the TV to the exception list.
💡
The stability of the connection depends on the quality of the router and its location relative to the TV and phone.
Comparison of methods and final recommendations
Each of these techniques has its own strengths: Wireless technology is convenient for showing photos and watching videos, whereas cable is necessary for games or working with text, where font clarity is important.
SmartThings applications provide better integration by allowing you to control your TV as a native device. Standard protocols (Miracast) are good for their versatility and no need to install additional software.
Choose the method depending on the task: for evening movies suitable DLNA or Smart View, for presentation – Miracast, and for game emulators – only HDMI.
