Modern multimedia capabilities allow you to turn any smartphone into a powerful control center for the home theater. Xiaomi users often face the need to display an image on the big screen to enjoy a favorite movie or presentation. Samsung TV owners have several effective ways to accomplish this task, from simple wireless protocols to wired connections with high bandwidth.
The choice of the specific method depends on the model of your device, the version of the operating system MIUI or HyperOS, and the availability of additional hardware. It is important to understand that the quality of data transfer directly affects the resolution and stability of the picture. In this article, we will discuss all the options available in detail so that you can choose the best one for your situation.
There are both regular Android tools and specialized applications from Samsung developers, some methods require a connection to one Wi-Fi network, others work completely autonomously, and we will look at the technical nuances of each approach to eliminate possible errors in the configuration.
Wireless broadcasting via built-in Miracast protocol
The most common and convenient way is to use wireless display technology. In the Xiaomi ecosystem, this feature is often called “Translation” or “Wireless Monitor”, and on Samsung TVs it is implemented through the Miracast protocol. It does not require the installation of third-party software to start, since all the necessary components are already built into the system.
The process of pairing devices is as simple as possible for the convenience of the user, you need to make sure that both gadgets are connected to the same wireless Wi-Fi network. This is a critical condition, without which device detection is impossible.
On a Xiaomi smartphone, you should lower the notification curtain and find the Translation icon. If it is not available in quick access, you can go to Settings → Connection and Sharing → Broadcast. Once the function is activated, the phone will start searching for available signal receivers.
On a Samsung TV, you may need to allow a pop-up connection or select the source of the Screen Mirroring signal from the source menu. Once the devices find each other, a confirmation request will appear on the TV screen.
What to do if you can’t see the TV?
It’s worth noting that when using this method, the smartphone screen is completely duplicated on the TV, which means that any notifications, incoming calls or user actions will be visible on the big screen. For viewing videos from the gallery, this is the ideal option, allowing you to control playback directly from the phone.
Using SmartThings App to Manage Content
Samsung has developed its own smart home ecosystem, centered around the SmartThings app, which not only manages appliances, but also streams media content from mobile devices to the brand’s TVs, and is available through the Google Play Store on any Android device.
Unlike a simple screen broadcast, SmartThings allows you to transfer specific video or photo files without taking up your smartphone screen. You can continue to use messengers or browsers while the TV is on the movie, which is especially convenient for long viewings.
To get started, you need to log in to the app using your Samsung Account. After adding the TV to the list of devices, a media management button will appear in the interface. Select a file in the Xiaomi gallery, click the “Share” button and select from the SmartThings or Smart View list.
- 📺 High resolution support to 4K if relevant content is available.
- 🔋 Savings in smartphone battery power compared to full screen broadcast.
- 🎮 The ability to use the phone as a remote control.
- 📁 Access to files in cloud storages linked to an account.
The app also allows you to create automation scenarios, for example, when you start a video on your phone, the TV can automatically turn on and switch to the desired signal source, but you need a powerful router that supports Wi-Fi 5 or Wi-Fi 6 standards to work reliably.
💡
For maximum connectivity stability through SmartThings, place the router at the same distance from the TV and smartphone, avoiding screening structures made of concrete or metal.
DLNA technology and built-in video player Xiaomi
Another effective method of video transfer is the use of the DLNA protocol (Digital Living Network Alliance). Standard video players in the MIUI shell and HyperOS often have a built-in casts feature that allows you to find devices on the local network. This method does not require installing additional applications on the TV, as long as it supports media servers.
The process is as follows: you open a video file in a gallery or video player Xiaomi, click on the icon broadcast (rectangle with waves) and choose your Samsung TV. TV in this case acts as a renderer, taking the data stream and decoding it on your own.
The advantage of this is that the phone is just a remote control, so once you start playing, you can lock the screen of the smartphone or exit the app, and the video will continue to play on the TV, which frees up the resources of the mobile device.
However, there are limitations on file formats that are supported, and if the video is encoded in a rare codec, the TV may not be able to play it, giving a format error, and in such cases, it is recommended to use third-party players with their own codecs.
| Parameter | Miracast (Translation) | DLNA (Media Server) | SmartThings |
|---|---|---|---|
| Booting the phone's processor | Tall. | Low. | Low. |
| Background work | No (screen on fire) | Yes. | Yes. |
| Image quality | Depends on the Wi-Fi signal. | Original (without compression) | Original |
| Support for DRM Content | Partial | No. | Yes (via annexes) |
💡
DLNA is the best choice for watching pre-downloaded movies in high quality, as it provides minimal load on the smartphone and a stable flow of data.
Wired connection via USB-C and HDMI
For users who want maximum image quality and no delay, the only solution is wired connectivity. Using a USB-C to HDMI adapter allows you to transmit video digitally without compression and loss. However, there is an important technical nuance regarding the hardware of Xiaomi smartphones.
Not all phone models support image output via a charging port. DisplayPort Alt Mode interface or Thunderbolt technology is required to work. flagship models of the Xiaomi 13, 14, Mix series usually have this support, while budget segments (Redmi Note, Poco) often lack this feature and the adapter will not work.
If your smartphone supports video output, the algorithm of actions is simple: connect the adapter to the phone, and to the adapter – an HDMI cable that goes to the TV. On the TV, you need to switch the signal source to the appropriate HDMI port 1 or HDMI 2.
If you successfully connect to the TV, you will see a smartphone desktop, depending on the version of MIUI, you may activate the Desktop Mode, which adapts the interface to the large screen, or simply clone the image.
It is important to consider that when wired, the phone can quickly discharge, as there is an active power consumption. It is recommended to use an adapter with an additional power port (PD Charge) to simultaneously charge the device while viewing.
Broadcasting via Chromecast and Google Home
Many modern Samsung TVs support Google’s Chromecast platform or have a corresponding module in the Tizen system.This allows you to stream content directly from apps like YouTube, Netflix or VLC Player using Google’s infrastructure.
To implement this method, the Xiaomi smartphone must have a Google Home app installed. Once you set up and detect the TV in the app, you can stream the entire screen of the smartphone. Go to the device management in the Google Home app and select Translate screen.
This method is low latency and good coding quality, and it's particularly effective when watching online video services, because the TV itself decodes the video stream, only getting a link to the source, which reduces the load on the Wi-Fi channel compared to Miracast.
⚠️ Note: When using Chromecast, make sure that the TV has updated the YouTube app and Google Play services. The outdated version of the software can lead to dissynchronization of sound and image.
You can also create multi-room audio device groups through Google Home, but in the context of video, this provides a stable connection even with a weak router signal, thanks to Google’s optimized protocols.
Network solution and configuration
Despite the simplicity of technology, users often face problems connecting, and the most common reason is the splitting of Wi-Fi frequencies. Routers often broadcast two networks: 2.4 GHz and 5 GHz. If the phone is connected to one and the TV is connected to another, they may not see each other even when on the same network.
To solve this problem, you need to log into the router’s settings and make sure that the client isolation function (AP Isolation) is turned off, and it is also recommended to combine the network names (SSID) for both frequencies or force both devices to connect to a 5 GHz network for better bandwidth.
Another cause of failures could be an antivirus or firewall on Xiaomi's smartphone, which blocks local connections.Check the permissions for broadcast apps and make sure they're allowed access to the local network.
☑️ Diagnostics of connection
If the image twitches or is low resolution, try restarting the router. The accumulation of errors in the router buffer is a common cause of problems with streaming large amounts of data.
