Modern users often face the need to display multimedia content from a mobile device to the big screen. The bundle of Xiaomi smartphone and Samsung TV is one of the most popular, but not always obvious in the setup. Device owners wonder how quickly and wirelessly to start watching movies or show presentations.
There are several proven synchronization methods, each with its own advantages: wireless technology eliminates the chaos of cables, while wired connection guarantees maximum signal stability, and the choice of the specific method depends on the model of your TV and the version of the MIUI operating system.
In this article, we will take a look at all the connectivity options available, from built-in system functions to third-party utilities, and learn about network setup, data protocols, and how to solve common errors.
Use of the built-in broadcast function in MIUI
The easiest and fastest way to transmit an image is to use a system feature that is built into the default MIUI shell, which is based on the Miracast standard supported by most modern Samsung TVs with Smart TV function. You do not need to install additional software if both devices are in good working order.
To get started, you need to make sure your smartphone and TV are connected to the same Wi-Fi network. This is a critical condition, since the data transfer goes through the local router. If the networks differ (for example, one at 2.4 GHz and the other at 5 GHz, and the router isolates them), the devices may not see each other.
⚠️ Note: Some older router models may not handle the multicast traffic required for Miracast to work properly. If the device search doesn't work, try temporarily disabling the feature"AP Isolation in the router settings.
To activate the feature, lower the notification curtain and find the "Translation" or "Cast" icon. In some versions of the firmware, it may be called "Wireless Monitor." Once you press it, the phone will start looking for available displays within network range. When your Samsung TV appears on the list, just click on it to pair.
You can see a request for permission on your TV screen, use the remote control to confirm the entry, the image from the smartphone screen will instantly appear on the TV, you can flip the phone into horizontal mode, and the picture will occupy the entire screen, which is ideal for watching video.
Smart View setup on Samsung TV
On the other side of the barricade is the TV itself. In the Samsung ecosystem, wireless image technology is often implemented through Smart View. While current models support direct Miracast reception without unnecessary settings, in some cases, you need to activate the device's visibility in the menu.
Take the remote control and press Home or Menu. Go to the settings section, which can be called Network or Connection. You'll need to find the item that provides the mobile connection manual, which in the old models could be called AllShare or Samsung Connect.
Make sure that the image reception function is enabled. Often the default is "Audio Only" or "Off" mode, which blocks the transmission of video streams from Xiaomi phones. Change the setting to "Full access" or "Screen Translation" This will allow the smartphone to initiate a connection.
- 📺 Go to the Smart Hub menu on your TV.
- 📡 Make sure Wi-Fi Direct is enabled in network settings.
- 🔒 Check the list of blocked devices in case of an erroneous ban.
- 🔄 Restart the TV if it doesn’t show up in search.
It is worth noting that protocols may vary depending on the year of release. Samsung’s new Tizen models have more advanced detection algorithms, while older Orsay-based models may require more careful manual IP-addressing.
Why isn't the TV on the list?
Application of Samsung SmartThings application
If standard methods don’t work or advanced controls are required, the best solution is the official SmartThings app. This is a universal control panel for the Samsung ecosystem, which is available in the Google Play store for Xiaomi devices.
Once you install the app, launch it and log into your Samsung Account. The program will automatically scan the network and find compatible devices. If the TV is new, you may need to enter the code displayed on the TV screen to confirm the pair, which ensures the connection is secure.
In the app interface, select your TV from the list of devices. In the control menu that opens, find the screen Translation button or the smartphone and screen icon, and clicking on it will trigger the mirroring process, and the advantage of this method is a more stable connection and the ability to transmit sound even in the background of some applications.
| Function | Built-in broadcast | SmartThings app | HDMI cable |
|---|---|---|---|
| Image quality | Depends on Wi-Fi. | High. | Maximum (Lossless) |
| Delay (Latency) | Medium | Low. | Absent. |
| TV administration | No. | Complete. | No. |
| Battery consumption | High-pitched | Medium. | Low (charging in) |
The use of official software is especially relevant for owners of flagship models Xiaomi and Redmi, where the system can aggressively save energy and close the background broadcast processes. SmartThings application has the necessary permissions and priorities in the system, which minimizes the risk of communication interruption.
☑️ Checking before installing SmartThings
Broadcasting via Google Home and Chromecast
Many modern Samsung TVs support the built-in Chromecast built-in platform, which allows you to stream content directly from apps like YouTube, Netflix or Google Photos without mirroring the entire screen of your smartphone.
Download and install the Google Home app from the Play Store. Open it and make sure you use the same Google account as you do on your TV (if you need authorization). The app will find your TV online. Click on the device icon and select the "Cast my screen" button.
This method is particularly effective for high-resolution video viewing, as the TV downloads the stream from the Internet itself, and the phone acts only as a remote control, which reduces the load on the battery of the Xiaomi smartphone and reduces the heating of the device, while the picture quality remains stable even in the presence of interference in the air.
⚠️ Note: When using Chromecast, some DRM-And the protected applications can block the recording of the screen, and then you'll see a black image with sound working.
If you don't have a Chromecast built in, you can buy a Chromecast with Google TV and plug it into an HDMI port, and the algorithm stays the same: the phone and the console must be on the same network, making any, even an old TV, a smart platform.
Wired connection via HDMI and USB-C
For users who want maximum reliability and no delays, wired connectivity is ideal. However, there is an important caveat: not all Xiaomi smartphones support video output via a USB Type-C port. This feature is called MHL or DisplayPort Alt Mode.
To check for support, check out the specifications of your model. Xiaomi's flagship series (e.g. Mi 10, Mi 11, Xiaomi 12/13/14) typically support video output, while the budget models of the Redmi Note series often lack this capability. If support is available, you'll need a USB-C to HDMI adapter.
Connect the adapter to your smartphone, then connect it with an HDMI cable to your TV. Switch the signal source on your TV to the appropriate port (e.g. HDMI 1). The image should appear automatically. Unlike wireless methods, it does not require Wi-Fi setup, which makes it indispensable in the absence of Internet.
- 🔌 Buy a quality adapter with support 4K.
- 📱 Make sure your phone supports DisplayPort over USB-C.
- 📺 Select the correct source of the signal (Source) on the remote.
- 🔋 Use an adapter with an additional charging port.
The advantage of this connection is that it can charge your smartphone at the same time (if the adapter has a power port) and not compress the video stream. The picture is transmitted in the original digital form, which is critical for designers or when showing small text, and the input delay when playing games is also reduced to zero.
💡
Use an HDMI adapter with a separate USB port for power, as the video output mode consumes the battery of the smartphone.
Solution: Why there is no image or sound
Even with the right setup, users can face technical problems. One of the most common is the lack of sound when a successful image is transmitted. On Android on Xiaomi phones, the default sound can continue to go through the phone speaker. To change this, start playing the media file, click on the speaker icon in the notification curtain or in the broadcast interface, and select the Samsung TV output device.
Another common problem is audio and video desynchronization or constant buffering, which is a direct sign of poor Wi-Fi signal strength. Try getting closer to the router or switching the TV to a wired network connection (LAN) if you can, and rebooting the router also helps.
If the phone screen goes out and the broadcast stops, check the power saving settings. Go to Settings → Battery → Energy Saving and select No Limits mode for the application you use to broadcast, or for the system process Translation. Aggressive MIUI optimization often kills background processes.
⚠️ Note: When connecting through HDMI Use the P.Size or Format buttons on the Samsung remote to change the aspect ratio to 16:9 or Original, otherwise the image may be stretched or cropped.
In rare cases, you may need to reset your network settings. On your TV, you can do this through the support menu, and on your phone through Settings → Connection and Sharing → Reset Wi-Fi and Bluetooth. Remember, this will remove saved passwords from the networks.
💡
The stability of the wireless connection depends on the congestion of the Wi-Fi channel. In apartment buildings, it is better to use the frequency of 5 GHz.
