Today’s users often have to stream content from their smartphones to the big screen, and the bundle of devices from different manufacturers — for example, the Samsung Galaxy and Xiaomi Mi TV — is one of the most common configurations in home media systems. Although Android operating systems in both gadgets can differ in branded shells (One UI vs. MIUI TV), the basic wireless data protocols remain universal, which allows you to enjoy movies, photos and games without unnecessary wires on a wide diagonal.
The main challenge for owners is that feature names may differ from brand to brand, and standard settings menus are not always obvious to the beginner. Wireless connection is usually built on Miracast or DLNA technologies, which are built into the Android core, but their activation requires a certain algorithm of actions. In this article, we will discuss in detail all ways of synchronization, from regular tools to third-party applications.
Before you start setting up, make sure your equipment is ready to go. It is important to understand that the stability of high-resolution video transmission directly depends on the quality of the radio module and indoor conditions. Wi-Fi Direct, which is often used for this purpose, is sensitive to interference, so the correct preparation of equipment is the first step to successful broadcast without delay and desynchronization of sound.
Preparation of equipment and basic requirements
The foundation for a successful connection is to have both devices on the same LAN, which means that both your Samsung and Xiaomi are on the same LAN. TV If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, it is desirable that both devices operate in the 5 GHz band, as it provides the higher bandwidth required for the network to be used. 4K-content.
Check the software's relevance on both devices. On a Xiaomi TV, you can do this through the settings menu, and on a Samsung smartphone, you can do this in the system updates section. Outdated Wi-Fi drivers can block devices from being discovered by each other or cause connection breaks while you're watching.
⚠️ Note: Guest Network often isolates devices from each other for security reasons.If the TV can't see the phone, check if you're connected to the guest.SSID.
Also worth considering is energy saving. When the screen is broadcasting, the Samsung smartphone can quickly discharge, and the One UI energy saving system can try to limit the background activity of the Wi-Fi module.
To test basic connectivity, you can try opening any website on your phone and running video on your TV through your built-in browser to make sure the Internet is working at both ends of the chain. If there is Internet but the devices can't see each other, the problem lies in the local detection settings or the router's firewall.
Broadcasting through Smart View (Miracast)
The most popular and convenient way for Samsung owners is to use the native Smart View feature, which is based on the Miracast standard, which allows you to transmit a screen image in real time with minimal latency. Unlike DLNA, it broadcasts exactly what you see on the smartphone display, including the interface and notifications.
To start the process, lower the notification curtain on your Samsung phone and find the Smart View icon. If it's not on the first page, swipe left or tap three dots to edit the panel. Once activated, the phone will start searching for available displays within Wi-Fi range.
☑️ Checklist for Smart View
When your Xiaomi Mi TV comes up, tap the name of the TV. You may see a request for permission to connect on your TV screen — check it with the remote. It's important to note that the quality of the picture depends on the load of the wireless channel. If you notice twitching, try to get closer to the router.
In some Xiaomi TVs, Miracast's signal reception feature may be called Wireless Display, Miracast, or integrated into an app (Mi Cast). If the phone doesn't find TV, open the app manually on your TV before searching on your smartphone.
Smart View also allows you to use your phone as a touchpad or only display the image on part of the screen if the TV supports Picture-in-Picture mode. However, it is worth remembering that when the smartphone screen is turned off, the broadcast usually stops, as the video stream from the matrix is transmitted.
Use of DLNA protocol and Mi Video application
If your goal is not to duplicate the screen, but to simply play a video file, a photo or music stored in Samsung’s memory, you’d better use the DLNA protocol, which is less resource-intensive and provides a more stable playback of heavy content, as the TV itself decodes the stream, receiving only data.
In the Xiaomi ecosystem, this is often done using the Mi Video app (or just Video) that is preinstalled on many TV models. On the Samsung side of the smartphone, you can use the standard gallery or the same Mi Video if installed. The algorithm is simple: open a file on your phone, press the Translate button (the arrow screen icon) and choose a TV.
| Parameter | Miracast (Smart View) | DLNA (Cast) |
|---|---|---|
| Type of transmission | Screen streaming video | Broadcasting of a media file |
| Impact on the phone | The screen should burn. | We can turn off the screen. |
| Quality. | Depends on the Wi-Fi signal. | Original File Quality |
| Management | Phone from phone. | From the phone or remote |
The advantage of DLNA is that you can roll the app on your phone, answer a call, or even lock the device, and playback on your TV won't be interrupted.
Why does DLNA not work with some formats?
It is worth considering that for DLNA to work, both devices must have access to a local network. Antiviruses or firewalls on the router sometimes block ports used to find media servers. This is rare on standard home networks, but in corporate or complex home configurations, rules may need to be set up.
Aggregator Apps: Google Home and Xiaomi Home
For users who want centralized management, installing official aggregator apps is a great solution. Google Home is the de facto standard for Android TV, which is often preinstalled or available in the Play Market store on Xiaomi TV.
Run Google Home on a Samsung smartphone, find your Xiaomi TV in the device list. From the device menu, select the option to Translate the screen. This method is especially useful if the regular Smart View is unstable for some reason, since Google uses its own alarm servers to connect.
The alternative is Xiaomi Home (Mi Home), which, while it manages the smart home, in some regions and on some TV models, it allows basic media server functions, but Google Home or Smart View are usually more efficient for broadcasting the screen.
⚠️ Note: When using Google Home, make sure that on Xiaomi TV, Google Cast is allowed in the developer settings or app menu. TV Third-party applications’ access to Cast may be restricted.
Using third-party apps also opens up additional features, such as creating playlists or controlling playback queues, which makes the smartphone a full-fledged multimedia center control panel.
Wired connection via USB-C to HDMI
Wireless technology is convenient, but it can’t guarantee 100% stability and no delays, which is critical for gamers or when showing presentations. Owners of Samsung’s flagship models (S, Note, Z series) can use wired connectivity, since their USB Type-C port supports the DisplayPort Alt Mode standard.
You'll need a USB-C to HDMI adapter to do this. Just connect the adapter to your phone, and connect the HDMI cable to your Xiaomi TV. Switch the TV source to the appropriate HDMI port. The image will appear instantly, without the need for Wi-Fi settings.
The advantage of this method is the lack of compression of video stream and input lag. The phone can work in DeX mode (if supported), turning the interface into a desktop, which is extremely convenient for working with documents on a large screen.
💡
Use externally powered adapters USB-port, if you plan to work long hours, video transmission HDMI It is energy-consuming, and the phone can run out faster than usual if you do not apply power to the adapter.
Samsung’s budget models (Series A, M, J) often do not support video transmission over USB, having only USB 2.0 standard for charging and data, in which case wired connection is impossible without the use of special docks with DisplayLink technology, requiring the installation of drivers.
Troubleshooting and troubleshooting
Even with the right setup, there can be failures. One of the common problems is that the TV sees the phone but doesn't connect, or the connection is constantly broken. IP-address.
Try restarting the router, completely de-energizing it on 10-15 And the other way to do that is to forget the Wi-Fi network on both devices and re-authorize with a password, and it resets the network caches.
If there is an image but no audio, check the audio output settings in the Smart View menu on your phone. Sometimes the sound stays on your phone unless you switch the device profile when you connect. In Bluetooth and Samsung device settings, select the TV as the audio output device.
⚠️ Warning: Android antivirus apps can block incoming connections for the feature DLNA. If the TV stops seeing files in the gallery, temporarily disable network protection in antivirus.
In the case of persistent lags when broadcasting wirelessly, lower the output resolution in Smart View settings (if available) or close the background apps on the phone that consume traffic. The most common cause of problems is using the 2.4 GHz band in an apartment building where the channels are clogged with neighboring routers; switching to 5 GHz solves 90% of the problems.
💡
The stability of a wireless connection depends on the frequency of Wi-Fi and the absence of physical obstacles between the router and devices.
