Today's users often face the challenge of displaying a smartphone image on a big screen to watch a high-resolution movie or show photos to friends. Devices from different ecosystems, particularly Samsung and Xiaomi, sometimes feel that this is impossible because of the differences in the operating shells. But wireless data standards are universal, and it's easy to connect these brands with the right algorithms.
The basis for interaction is Miracast technology, which is built into most modern TVs with Smart TV and Android smartphones. DLNA protocols are also actively used to transfer media files and Google Cast for streaming content from applications. Understanding the difference between these methods will allow you to choose the most suitable option for a particular task, whether it is a game, watching a video or a presentation.
In this article, we will take a look at all the connectivity options available, from built-in features to third-party apps that ensure stable performance, how to minimize latency and how to maximize image quality without compression artifacts.
Preparatory stage: Network and device setup
Before any manipulations, make sure that both devices are in the same network environment. Wi-Fi is the foundation for wireless video transmission, and any interruptions in its operation will lead to desynchronization of sound and image. Make sure your router supports 802.11ac or newer, as older protocols may not provide sufficient bandwidth for broadcasting in 4K.
Both gadgets need to be connected to the same access point. If you have a dual-band router that broadcasts 2.4 GHz and 5 GHz networks, it is better to use 5 GHz frequency to reduce interference and increase data transfer speeds. However, it is worth remembering that the 5 GHz range has a shorter range, so devices should be in close proximity to each other.
☑️ Checking before connection
It is also recommended to check for firmware updates on the Xiaomi Mi TV and software on the Samsung Galaxy smartphone. Manufacturers regularly release patches that improve the compatibility of the DLNA and Miracast protocols. Ignoring this step can lead to the fact that devices simply “do not see” each other in the list of available receivers.
⚠️ Note: If your router uses Client Isolation, devices will not be able to communicate even when connected to a single network.
Smart View Method: A Native Solution for Samsung
The easiest and most efficient way for smartphone owners of the South Korean brand is to use the built-in Smart View feature, which is based on the Miracast standard and allows you to duplicate the phone screen on the TV in real time without the need to install additional software.
To activate the feature, you need to lower the notification curtain on your Samsung phone and find the Smart View icon. In some models, it can hide in the second quick settings menu available by swipe to the left. Once you click, the system will start searching, and in a few seconds the name of your Xiaomi TV or Mi TV will appear on the phone screen.
- 📱 Click on the Smart View icon in the Quick Settings panel.
- 📺 Select your TV from the list of devices offered.
- 🔗 Confirm the connection on the TV screen if you receive a request.
- 🎮 Enjoy content on the big screen with minimal latency.
An important advantage of the method is that it supports playback control directly from the locked screen of the phone. You can switch tracks or pause videos without unlocking the smartphone. However, it should be borne in mind that when you duplicate the screen in horizontal mode on the phone may appear black stripes on the sides, if aspect ratio_ The content does not match the TV screen.
💡
To reduce latency in games through Smart View, close all background apps on your phone to free up the CPU resources to encode the video stream.
Using the Google Home app for broadcasting
If the built-in tools are unstable or the Xiaomi TV is running Android TV, the official Google Home app is an excellent alternative solution, which is especially relevant since many modern Xiaomi TVs use pure Android TV, which natively supports the Google Cast protocol.
The app allows not only to duplicate the screen, but also to control the smart home, but in our context we are interested in the broadcast function. Once the app is installed and logged in to a Google account, it will automatically detect all Chromecast built-in devices on the network. Xiaomi TVs often have a built-in Chromecast, making them fully compatible with this method.
The connection process takes seconds. You have to find your TV card in the app interface and press the Broadcast button. The system will request confirmation, and then the image from the phone will appear on the large display. The image quality is often higher than with Miracast, because it uses a more efficient compression codec.
⚠️ Note: When using Google Home, your phone and TV must have access to Google servers. If the TV doesn’t have Google Play services installed, this method may not work.
Broadcasting via Mi Remote and Mi Video
Xiaomi’s ecosystem offers its own tools to interact with the brand’s tech, and ignoring them would be a mistake.The Mi Remote app is primarily designed to control the TV via an IR port or Wi-Fi, but it also has features for media transfer. In addition, the built-in Mi Video player on Xiaomi TVs often supports the function of receiving files over the network.
To implement this method, you need to install the Mi Remote app on a Samsung smartphone. After pairing devices in the application, you will access the control menu. In some versions of the software, you can use the "Translation" or "Cast" function, which allows you to send photos and videos from the phone gallery directly to the built-in media player of the TV.
The good thing about this method is that it's less demanding on the Wi-Fi network when playing local files, because it uses the DLNA protocol. The TV itself downloads the file over the network, unloading the phone. However, for desktop duplication (screencasting), this method is not suitable, it is designed exclusively for media files.
- 📥 Install Mi Remote from the Google Play Store.
- 📡 Add your Xiaomi TV to your device list.
- 🖼️ Select a file in the gallery and click the "Translate" button".
- 📺 The file will open in the native player of the TV.
Third-party applications for advanced users
When the standard tools are not working properly or require advanced features, third-party solutions come to the rescue. One of the most popular and reliable applications is Castify or Web Video Caster, which can pull video streams from browsers and applications that do not have a built-in broadcast button and send them to the TV.
The way these apps work is to create a local server on the phone or send a stream link directly to the receiving device, allowing content to be streamed from sites that block standard casting practices. For Samsung and Xiaomi bundles, this is often the only way to watch videos from unverified resources on the big screen.
Installation of Web Video Caster Receiver on TV (if required)
Launching the application on the phone
Selection of the device in the list of availableIt's worth noting that free versions of these apps often contain ads that can interrupt the browsing process, paid versions take away this drawback and offer a more stable connection, and they allow you to customize subtitles and select audio tracks, which is critical for viewing foreign content.

Comparison of Connection Methods and Their Characteristics
To make it easier for you to choose the best way, we have systematized the main characteristics of each method in a table, which will help you quickly navigate which protocol is best for your tasks: playing, watching movies or working with documents.
| Method | Delay (Latency) | Quality. | Difficulty |
|---|---|---|---|
| Smart View (Miracast) | Low. | High (Full HD/4K) | Minimum |
| Google Home (Cast) | Medium | Very high. | Low. |
| Mi Remote (DLNA) | N/D (for files) | Original | Medium |
| Third-party annexes | Depends on the software. | Variable | Tall. |
As you can see from the table, Smart View is best suited for gaming due to its low input latency. Google Cast is ideal for viewing online cinemas, which takes the decoding load on itself. Local files are most convenient to run through DLNA or Mi Video built-in tools.
⚠️ Note: When using high-compression techniques (some third-party applications), the text on the screen may become unreadable.
Solution: Problems and their elimination
Even if you follow all the instructions, you can run into technical difficulties, and the most common problem is that the TV can't see the phone, so you should check the firewall settings on the router and make sure that the antivirus on the smartphone doesn't block local connections, and sometimes it helps to just restart the Wi-Fi module on both devices.
Another common complaint is that audio and image desynchronization is treated either by reducing the broadcast quality in the application settings or switching to a wired connection if the situation is critical, and checking if the Wi-Fi channel is overloaded by neighboring routers, and changing the channel in the router settings if necessary.
💡
Connection stability is directly dependent on the quality of the Wi-Fi signal; the use of repeaters can increase latency and worsen the quality of the broadcast.
If the image twitches or is low resolution, check if the phone is power-saving mode is on.It often limits the Wi-Fi module's performance to save battery power, which negatively affects streaming.
