Today’s users often face the challenge of showing their smartphone content on the big screen, with Xiaomi and Samsung in a winning position as both companies adopt advanced wireless data technologies. Screencasting not only allows them to watch videos from the Internet, but also to show presentations, photos or play mobile games on a wide diagonal of the TV, which turns a normal viewing experience into a full-fledged multimedia experience.
There are several proven methods that allow you to sync devices without using unnecessary wires. The main technologies here are Miracast and DLNA, built directly into the Android operating system and the MIUI shell. You do not need to be a technician to set up a connection in a few minutes.
In this article, we will take a closer look at all the ways you can connect, from built-in features to specialized applications. We will look at the nuances of setting up Wi-Fi Direct and how you work through third-party services. We will also look at possible connection problems and how to solve them so that you can enjoy content without delays and artifacts.
Use the built-in Smart View feature on Samsung
The easiest and most reliable way to install additional software on a smartphone is to use the native Samsung Smart View feature. However, since this option is built into the ecosystem of the Korean brand, Xiaomi owners will have to use an intermediary app.
To get started, download the SmartThings app from the Google Play store. Once installed, open the program and log in to your Samsung account. Make sure your phone and TV are connected to the same Wi-Fi network. The app will automatically start searching for available devices on the local network.
- 📺 Open the app and click the device add button in the upper right corner.
- 🔍 Wait until your Samsung TV is on the list.
- ✅ Click on the TV model name and confirm the pairing on the TV screen.
- 📡 Select the option "Screen Translation" or "Mirror Screen" in the control menu.
Once you pair a Xiaomi display image with a successful interface, it will instantly appear on your TV. It is important to note that the quality of the transmission depends on the speed of the wireless network. If you plan to watch high-resolution video, make sure that the router supports the 5 GHz standard, which will provide a more stable data flow without buffering.
Broadcasting via built-in Chromecast in MIUI
Many modern Xiaomi smartphones have a built-in streaming feature based on the Google Cast protocol, which allows you to transfer content directly to applications that support the technology, or duplicate the entire screen, which is often more stable than using third-party applications, since it is deeply integrated into the system.
To activate this feature, lower the notification curtain down and find the "Translation" or "Cast" icon. If the icon is not, click on the menu edit button (usually a pencil icon or three dots) and drag the "Translation" element to the active bar. Once activated, the phone will start searching for Samsung devices that support Chrome builtcast-in.
Some Samsung TVs may require pre-activation of the signal reception function. To do this, click the Home button on the remote control, go to the app menu and find the Smart View or Screen Mirroring app on the TV itself.
💡
To reduce delay (lag) when playing or watching videos, try to get closer to the router. distance of more than 5 meters through two concrete walls can significantly degrade the picture quality.
It's worth considering that when you stream the whole screen through Google Cast, the phone can get hotter. This is normal, because the processor actively encodes the video stream in real time. If you notice a big drop in smartphone performance, try lowering the resolution of the broadcast image in the feature settings.
Application of Miracast technology (Wireless display)
Miracast is the standard for wireless video and audio transmission without compression, which ensures high image quality. Unlike Chromecast, which uses Internet protocols, Miracast creates a direct connection between devices (Wi-Fi Direct), which means that even without Internet access, broadcasting will work if devices see each other.
On Samsung TVs, this feature is often referred to simply as Wireless Display or Screen Mirroring. On Xiaomi smartphones, the search can be called Wireless Monitor. The algorithm for action is simple: turn on the TV feature, then start a search on the phone through the stream menu.
However, there are limitations: Miracast is not natively supported in all applications, for example, some streaming services may block the transmission of protected content through this protocol due to the limitations of HDCP. In such cases, the screen may remain black, although sound will be transmitted.
| Parameter | Miracast | Chromecast | DLNA |
|---|---|---|---|
| Type of connection | Wi-Fi Direct (direct) | Through the router (local network) | Through the router (local network) |
| Internet dependency | No. | Required (for search and streaming) | No (local area network only) |
| Image quality | High (no compression) | Depends on the network. | Original file |
| Delay (Latency) | Minimum | Medium | Low. |
💡
Miracast is ideal for gaming and desktop displays, as it provides minimal latency when compared to other methods.
Multimedia Transfers via DLNA Protocol
If your goal is not to duplicate the screen in real time, but to play back the videos or photos you've already saved, then DLNA technology is the best choice. It allows you to transfer media files from your phone to your TV, which takes over the task of decoding, and it takes the load off the processor of your smartphone.
To implement this method, Xiaomi can use the built-in Mi Video video player or third-party applications, such as BubbleUPnP or VLC. Open the video file on your phone, click on the broadcast icon (rectangle with waves) and select your Samsung TV from the list.
The advantage of DLNA is that it supports a wide range of formats and codecs that the phone itself may not pull, but that a powerful TV processor can handle. In addition, you can control playback (pause, rewind) directly from your phone, using it as a remote control.
⚠️ Attention: When in use DLNA Make sure that your router does not include customer isolation AP (AP Isolation: This feature prevents devices on the same network from seeing each other, making it impossible to find a TV.
Third-party applications for enhanced capabilities
When regular funds are scarce, specialized applications from the Google Play store come to the rescue, the leader in this niche is the Web Video Caster app, which allows you to stream videos from sites that do not have a built-in Cast button, as well as transfer files of any format.
Another powerful tool is the LocalCast app, which is great at transferring photos and videos from a gallery, supporting subtitles and audio path selection. The interface is intuitive: you pick a file and then the output device.
- 📂 Web Video Caster – the best choice for online video from browsers.
- 🎬 LocalCast is ideal for local files with subtitles support.
- 🖥️ TeamViewer QuickSupport - allows you not only to broadcast, but also to control your phone from TV (requires installation of modules).
Using third-party software sometimes requires permissions to be configured. When you first run, the app will request access to the local network and files. To properly work the broadcast on Android 11 and above, you also need to provide permission to display on top of other windows. Without this, system restrictions can block image capture.
Why is there no sound when broadcasting the video?
Wired connection via USB-C to HDMI
For users who are critical to stability and maximum image quality, wireless methods may not work, in which case wired connectivity saves. However, there is an important caveat: not all Xiaomi smartphones support video output via a USB Type-C port.
Support for video output are mainly flagship models with USB 3.0/3.1 port and DisplayPort Alt Mode technology. Budget and mid-budget models often feature a USB 2.0 port that is physically unable to transmit video signals, limited only to charging and data transfer.
You will need an adapter to connect. USB-C to HDMI. Just connect the adapter to the phone and HDMI-Connect the adapter to the TV with a cable, switch the signal source to the TV to the appropriate port. HDMI. The image will appear automatically.
☑️ Checking before buying an adapter
⚠️ Note: When using a wired connection, the phone can quickly discharge if the adapter does not have an additional charging port (PD).
