How to display an image from a Xiaomi phone to a Samsung TV via Wi-Fi

Modern smartphone users often face the challenge of showing off content from a small screen on a large TV display, whether it’s a family photo album, an important presentation document, or simply an online video that the entire company wants to watch in high quality. Xiaomi and Samsung users often wonder about the compatibility of these devices, because their operating systems and proprietary protocols may differ. Fortunately, wireless data technologies have long ceased to be exclusive and available to everyone.

The main standard for this task is Miracast technology, which is built into most modern Android smartphones and Smart TVs. It allows you to transmit high-resolution video signals without loss of quality using a direct Wi-Fi connection. You do not need a router or complex network equipment, since the devices are connected directly via the Wi-Fi Direct protocol. However, there are nuances associated with the versions of the MIUI or HyperOS shells and Samsung Tizen TVs.

In this article, we will take a look at all the synchronization options available, from built-in system functions to the use of specialized applications. You will learn how to configure DLNA for media files and how to run a full-fledged live screen broadcast. The right setup will avoid delays and desynchronization of sound, which is especially important when watching movies or playing games.

Compatibility check and equipment preparation

Before you start setting up, you need to make sure that both devices are in good working order and support the necessary protocols.Most Samsung TVs released after 2015 are equipped with a Wi-Fi Direct module and support the Miracast standard. Xiaomi smartphones also have a built-in wireless display feature, which can be called differently depending on the version of the shell.

It is critical that both devices are connected to the same Wi-Fi network if you plan to use methods that require a router. If you use a direct Wi-Fi Direct connection, the Internet may not be necessary, but the stability of the modules should be high. Make sure that the TV includes external connection reception, which is often called Screen Mirroring or Screen Translation on the Samsung menu.

⚠️ Note: If your router is running in the 5GHz band, make sure both devices support this standard.Some older TV models may not see the 5GHz network, leading to a connection error.

For stable operation, it is also recommended to update the software of both devices to the latest available version. In Samsung TVs, this is done through the Support → Software Update menu, and in Xiaomi smartphones through Settings → About Phone → MIUI version. Having current Wi-Fi drivers eliminates many hidden compatibility conflicts.

Using the built-in Translation feature in Xiaomi

The easiest and fastest way to display an image is to use a system utility already integrated into the MIUI or HyperOS shell. This feature does not require additional software installation and works at the operating system level, providing minimal signal latency. To start, you need to open the notification curtain control panel and find an icon called Translation or Cast.

Once the feature is activated, the phone will start scanning available devices within range. If your Samsung TV supports Miracast protocol and is in standby mode, it will appear in the list. Click on the model name of the TV, and in a few seconds the image from the smartphone screen will appear on the large panel.

⚠️ Note: Some Samsung TVs require manually confirming the connection permission that will appear in the TV pop-up window. If this is not done, the connection will be severed after 30 seconds.

You can select the mode of operation in the broadcast settings. You can also use the options "Mirror" (full copy of the screen) and "Extension" (using TV as a second monitor if the application supports). To view the video in a horizontal orientation, just turn the phone, and the picture on the TV will also turn automatically thanks to the accelerometer.

If the standard utility doesn’t find the TV, try restarting the Wi-Fi module on both devices, sometimes helping to temporarily shut down the power saving mode on the smartphone, as it can limit the background operation of the network services necessary to maintain a stable connection.

Setup via Samsung SmartThings app

Samsung has developed its own SmartThings app, which is a universal control panel for the entire brand ecosystem. Although it was originally designed for Samsung devices, modern versions work perfectly with Xiaomi smartphones, allowing you to stream content and control the TV.

Once you have installed and registered your account, add your TV to your device list. The app will automatically find the TV on the local network if they are connected to the same router. In the TV control interface, select the option of Screen Translation or Smart View to start transferring the image, a method that often works more stable than the standard Miracast, as it uses optimized Samsung codecs.

The advantage of using SmartThings is the ability not only to duplicate the screen, but also to transfer specific media files from the gallery or video player without loading the phone's processor with full mirroring of the interface. You can also use the phone through the application as a touchpad or keyboard to type in text, which is very convenient when searching for content in YouTube or browser games.

In some cases, the first connection may need to be entered. PIN-The code displayed on the TV screen to the smartphone interface is a security measure to prevent unauthorized access to your display, and once successfully paired, the devices will be remembered, and the reconnection will occur automatically when you are on the same network.

Alternative applications for broadcasting (Third-party)

If the regular funds do not cope or require advanced functions, such as the translation of browser tabs from the DRM-And the leader in this niche is the Cast to app. TV - XCast or Web Video Caster, which can analyze the video stream on a page and send only the video track to the TV, unloading the smartphone.

To install, choose any high-rated app on the Google Play Store, such as Screen Mirroring or TV Cast for Samsung, and the same way of doing it: run the app on your phone, select your TV from the list, and click the connection button. Many of them support DLNA, which allows you to stream photos and videos from internal memory without mirroring the entire screen.

The browser-based broadcast feature deserves special attention: Many services protect content from copying by blocking the standard screen broadcast (a black screen with sound appears), and specialized caster applications are able to bypass this limitation by sending a link to the stream directly to the Smart TV, which already decodes the video itself.

It is worth considering that free versions of such applications often contain ads that can be displayed on the TV at the time of connection. For permanent use, it is recommended to purchase premium versions or use open-source analogues, which can be found in F-Droid repositories.

Comparison of Connection Methods and Their Characteristics

To choose the best way for your situation, you need to understand the technical differences between protocols. Miracast provides full mirroring, but can consume more power. DLNA is ideal for photos and video files, but not suitable for games or a browser. Protocols from Samsung and Xiaomi are trying to combine these capabilities.

The table below compares the main characteristics of different methods of connection, which will help to determine the choice depending on your tasks and equipment.

It is important for gaming to minimize latency, so a built-in Miracast or wired connection will be preferable.To watch movies in 4K, it is better to use the built-in Smart TV apps (YouTube, Netflix), sending a command from the phone, as this takes the load of decoding video from the smartphone processor.

💡

The choice of method depends on the purpose: for games - Miracast, for movies - DLNA or embedded TV applications, for photos - SmartThings.

Solving problems and eliminating mistakes

Despite the simplicity of the technology, users often face problems: the TV is not visible, the image is twitched or there is no sound. One of the most common reasons is the use of different Wi-Fi frequencies. If the router distributes 2.4 GHz and 5 GHz networks with different names, make sure that both the phone and TV are connected to one of them, preferably 5 GHz for high bandwidth.

If the connection is constantly broken, try changing the settings of the router. In some cases, disabling the function helps. WMM (Wi-Fi Multimedia) or, conversely, its inclusion, it is also worth checking whether the router is not limited to the number of simultaneous connections or filtering by means of filtering. MAC-Addresses that can block one of the devices.

Sound problems are often solved by switching audio output in the broadcast settings. Sometimes the default system continues to output sound through the phone speaker, in which case, in the broadcast control panel (usually swipe up or down during the broadcast), you need to select the Samsung TV audio output device.

If nothing works, reset network settings on a Xiaomi smartphone.This will remove stored Wi-Fi passwords and Bluetooth settings, but often eliminates protocol stack software errors. On a Samsung TV, you can perform a cold reset (off the socket for 1-2 minutes) to clear the cache of network services.

Optimizing image quality and performance

For best results, it's important to consider the resolution of the screen. If your TV supports 4K and your smartphone produces Full HD, the picture may look stretched or blurred. In the phone settings, you can try to change the output resolution, although many modern devices do this automatically, matching the parameters with the receiving device.

Close your smartphone background apps before you start streaming. The process of encoding a video stream in real time requires significant CPU and RAM resources. Having heavy games running or navigation can lead to friezes and twitches of the image on the large screen.

💡

To reduce latency in games, turn on the TV mode Game Mode. This will turn off the extra post-processing of the image, speeding up the response.

Also worth mentioning is the effect of distance. Wi-Fi Direct is sensitive to obstacles. Try to avoid thick walls or sources of strong electromagnetic interference between your phone and your TV (or router), such as microwave ovens running at 2.4 GHz.

Regularly cleaning the system cache and updating drivers through the app store will help keep the communication modules running smoothly.Don't ignore notifications about available firmware updates for the TV, as Samsung often releases patches that improve compatibility with newer versions of Android.
