Modern technology has turned a typical photo or video viewing experience on a smartphone into a real multimedia show on a big screen. Samsung and Xiaomi bundle owners often wonder how best to sync these devices to stream content. Fortunately, the Android ecosystem and the MIUI shell (or its new HyperOS analog) provide a host of built-in tools for this task without requiring the purchase of expensive additional hardware.
There are several proven methods, from wireless transmission over Wi-Fi to the use of physical cables, and the choice of the specific method depends on your goals: whether you want to just show a presentation to colleagues, stream a movie from an online cinema or run a mobile game on the full screen. Understanding the principles of Miracast and Chromecast will help you avoid typical connection errors.
In this article, we will discuss all the current connection options in detail, paying special attention to the nuances of working with different versions of TV and smartphone firmware. You will learn how to minimize signal latency and improve picture quality, as well as what to do if devices do not see each other on the common network.
Use of the built-in Screen Mirroring function
The easiest and fastest way to duplicate the screen is to use Miracast technology, which is built directly into the Android operating system. On Samsung smartphones, this feature is often called “Smart View”, and on Xiaomi TVs it can be integrated into the system menu or work through the “Mi Remote” app.
The activation process usually takes no more than a minute. You need to lower the notification curtain on your phone and find the "Smart View" or "Translation" icon. Once the scan is started, the phone will offer a list of available devices. If your Xiaomi Mi TV or Redmi TV is on and connected to the same network, it should appear in the list. Click on it and the image from the phone will instantly appear on the screen.
But there are nuances about security and encryption versions, and sometimes the TV requires a connection confirmation, and the TV display pops up with a code or permission request that the remote must accept, which is the standard procedure for protecting against unauthorized access to your display.
- 📱 Make sure that your Samsung phone has Wi-Fi and Bluetooth enabled, as these are often used for initial handshakes.
- 📺 On Xiaomi TVs with Android shell TV The feature may be called “Wireless display” and require manual start-up in settings.
- 📶 Using 5 GHz instead of 2.4 GHz significantly reduces latency and increases video stream stability.
⚠️ Warning: When broadcasting via Miracast, the phone can get very hot, as the video stream is encoded in real time. If you plan a long session, it is better to remove the protective case or connect the device to charge, but watch the temperature.
The quality of the image transmitted depends on the strength of the router signal. If you are far from the access point, you may see compression artifacts or desynchronization of the sound. In such cases, it is recommended to approach the router or use a wired connection if the TV model supports an Ethernet cable.
Broadcasting via Google Home and Chromecast
Most modern Xiaomi TVs run on Android TV, which means built-in support for Google Cast technology. This is a more advanced protocol than conventional mirroring, as it allows you to transfer content directly from the Internet servers without loading the smartphone processor.
Once you install the app and log in to your Google account, it automatically finds your TV on the network. When you click on the device icon, you'll see the "Translate Screen" button. Unlike Miracast, the phone acts more like a remote control, and buffering is done by the TV, which allows smoother video playback in high resolution.
A particular advantage of Cast is that you can stream content from individual apps, for example, you can run YouTube or Netflix on your phone, click the live stream button inside the app, and select the TV, so that the phone screen is free for other tasks, and the video goes to the TV.
☑️ Checking before connection
It’s worth noting that some Chinese versions of Xiaomi TVs may not have Google certification and, accordingly, built-in Chromecast.In this case, you will either have to reflash the device to the global version, or use alternative methods described below.
Application HDMI-cables and adapters USB-C
When wireless connectivity is impossible or maximum picture quality is required without compression, wired connectivity comes to the rescue. For Samsung smartphones with a USB Type-C port, there is MHL or DisplayPort Alt Mode technology that allows you to output video through a special adapter, which is ideal for gamers or those who want to watch a movie in 4K without lags.
You're gonna need an adapter «USB-C to HDMI» common HDMI-One end of the cable connects to the TV, the other to the adapter that plugs into the phone, and the TV automatically detects the new signal source, and you just have to select the appropriate port in the source menu (Input or Source).
It is important to consider that not all Samsung phone models support video output via USB. Flagship Galaxy S and Note series usually have this feature, whereas budget A series models can be limited to only data transfer and charging.Be sure to check the specifications of your model on the manufacturer's official website before buying an adapter.
| Type of connection | Image quality | Delay (Latency) | Dependence on Wi-Fi |
|---|---|---|---|
| Screen Mirroring (Miracast) | High (up to 1080p/4K) | Medium/High | Complete. |
| Google Cast | Maximum (up to 4K HDR) | Low. | Only for management. |
| HDMI Cable | No loss (Native) | Minimum | It doesn't matter. |
| DLNA (Local Files) | Depends on the format. | Low. | Complete. |
Why is there no sound through HDMI?
Using a cable guarantees connection stability, which is especially important for presentations or games where every millisecond of latency matters, and the phone in this mode often continues to charge if the adapter has an additional power port.
Translation of local files via DLNA
If your goal is to play a video file or show photos stored in your phone's memory, you don't have to duplicate the entire screen. DLNA technology allows you to stream media content directly to your TV using its built-in player, which frees the smartphone from constant operation and saves battery life.
Xiaomi TVs usually have a media player pre-installed that supports this standard. On a Samsung phone, you can use an integrated gallery or third-party apps like VLC for Android or BubbleUPnP. Open the video in the app, select the Translate option or the screen icon with an arrow, and the system will offer available devices.
The main advantage of DLNA is the ability to control playback (pause, rewind) from the phone while the TV is just playing the data stream, which also allows you to use the phone for other tasks without interrupting the movie on the big screen.
- 🎬 Support for a wide range of video and audio formats thanks to TV decoders.
- 🔋 Saving smartphone power as the screen can be turned off during playback.
- 📂 Ability to stream content from cloud storage if the player app supports it.
But remember codec compatibility, if the TV can't read the format of the video you're trying to run from your phone, it won't start playing even if the connection is installed, and in such cases, it's better to use the mirroring method.
Network setting and troubleshooting
Often, users are faced with a situation where the phone and TV are good but can't see each other. 90% of the time, the problem is network settings. Make sure both devices are connected to the same network, not the guest or neighbor network. Routers with a range of 2.4 GHz and 5 GHz can create different subnets, even if the network name (SSID) is the same.
Another common reason is the activated AP Isolation function in router settings, which prevents devices within the same network from communicating with each other, making it impossible for the phone to search for a TV. To solve the problem, you need to go to the router settings (usually at 192.168.0.1 or 192.168.1.1) and turn off this option.
⚠️ Attention: If you are using VPN On a smartphone, the local network may become inaccessible to detect devices. VPN-service.
Also worth checking out are software updates. On Xiaomi TVs, there are sometimes bugs in older firmware versions that interfere with Miracast. Updating the system through the Settings menu → About TV → System update can solve the compatibility problem.
💡
Try restarting the router if the devices stopped seeing each other after a long run. DNS table ARP-Addresses may be overflowing, which blocks the search for new devices on the local network.
Use of third-party applications
If standard tools don't work or the functionality isn't enough, third-party apps come to the rescue, and one of the most popular solutions is Web Video Caster or TV Cast for Samsung/Xiaomi, which allows you to stream videos from sites that don't have a built-in Cast button, as well as display files of specific formats.
The principle of their work is similar: you install the app on your phone and, in some cases, the companion app on your TV (via the Google Play store on the Internet). TV). After the interconnection, QR-When you search for code or search the network, the phone starts transmitting data to the TV.
Some apps offer advanced features such as mouse control from the phone screen, transfer files of any type or even run games with a gamepad emulator. However, it is worth considering that free versions often contain advertising, and the quality of the transfer may be inferior to system solutions.

Does the broadcast affect the speed of the Internet?
💡
Always choose Google Cast to watch online videos, and Miracast to play games or work with documents. HDMI-This will ensure the best balance of quality and performance.
So, transferring images from a Samsung phone to a Xiaomi TV is a multitude of ways. The choice of the optic method depends on your specific needs and network conditions. Experiment with different options to find the one that is right for you.
