Modern multimedia systems allow you to turn the living room into a real theater using a bundle of popular smartphones and smart TVs. Android ecosystem owners often face the need to showcase photos, videos or presentations on the big screen, but do not know how to properly organize the broadcast between different brands. The combination of a Samsung smartphone and a Xiaomi TV (based on Android TV or PatchWall) is one of the most common and functional tandems on the market.
The synchronization process can be done in a number of ways, depending on your goals and the hardware available. Wireless methods like Miracast and Google Cast provide fast wireless connectivity, whereas wired HDMI connectivity ensures maximum picture quality and no delays. The specific method depends on your TV model and the version of your smartphone operating system.
In this article, we will take a look at all the available streaming options, from built-in system features to third-party applications. You will learn how to configure high-resolution audio and image transmission, as well as how to fix typical connection errors. Properly configured, you will enjoy content from a mobile device on a full screen without loss of quality.
Device Preparation and Network Requirements
Before setting up, make sure both devices are in the same network conditions. For wireless broadcast protocols to work smoothly, it is critical that the Samsung Galaxy smartphone and the Mi TV are connected to the same Wi-Fi network. If your router has a 2.4 GHz and 5 GHz band division, it is recommended to use the same frequency for both gadgets to avoid detection problems.
Check the software’s relevance on both devices. On Xiaomi TV, go to the settings menu and find Settings → About TV → System Update. The firmware update often fixes data protocol errors and adds support for new codecs. On your smartphone, it’s also worth checking for updates in Settings → Software Update.
⚠️ WARNING: If you use a guest Wi-Fi network or a corporate network with customer isolation (AP Isolation, devices may not see each other, and then you can't stream without changing your router settings.
Make sure your TV has a wireless display feature on. Depending on the PatchWall or Android TV version, this option can be called differently. It usually activates automatically when you search for devices, but sometimes you need to manually run the Wireless Display or MiraCast app in the TV app list.
Broadcasting through the built-in Smart View feature
The easiest and fastest way to duplicate the screen is to use Samsung’s native Smart View feature, built into its One UI shell. This technology is based on the Miracast standard, which is supported by most modern Xiaomi TVs out of the box. To start, open the Quick Settings Panel on your smartphone with a thumb-down on the screen.
Find the Smart View icon (may be called a Translation or Wireless Monitor) and click on it. The smartphone will start searching for available devices within range. As soon as your Xiaomi TV appears on the list, tap its name. A confirmation request may appear on the TV screen — receive it using the remote control.
☑️ Check before connecting Smart View
Once paired successfully, the image from the phone will be completely mirrored on the TV screen, so you can switch between apps, and the picture will change accordingly.
- 📱 Open the notification curtain and find the Smart View.
- 📺 Choose your Xiaomi TV from the list of found devices.
- 🔒 Confirm the connection on the TV screen with the remote.
- 🎬 Enjoy the content on the big screen.
If the image looks stretched or doesn't fill the entire screen, use the proportions settings in the Smart View menu, which often allows you to choose Full Screen mode or change the aspect ratio by 16:9, especially for older models of phones with extended screens.
Using Google Chromecast technology
Most Xiaomi TVs run Android TV, which means built-in support for Google Cast technology. Unlike Miracast, which broadcasts the entire screen, Google Cast allows you to send specific content (video, music, photos) from apps directly to TV, using the phone as a remote control.
To work with this method, make sure that your smartphone has a Google Home app installed. Launch it and find your TV in the list of devices. If you want to stream videos from YouTube, Netflix or other supported services, just open the video in the app on your phone and click on the broadcast icon (a rectangle with waves in the corner).
⚠️ Note: When using Google Cast, video quality is adjusted automatically depending on the speed of the Internet. 4K HDR Requires a stable connection of at least 25 Mbps.
The advantage of this method is that you can use the phone for other tasks while the video is played on the TV. buffering occurs on the TV or streaming service side, so the battery discharge of the smartphone is much slower than with full screen duplication.
What to do if the Cast button does not appear?
There is also the option of fully streaming the Google Chrome browser tab. Open your browser on your phone, click the menu (three dots) and select Translate. You can send an open web page or even the entire screen of your phone to a Xiaomi TV. This is convenient for showing sites that do not have a native TV app.
Wired connection via HDMI and adapters
For users who want maximum image quality without compression, or in conditions of poor Wi-Fi signal, the best solution will be wired connection. Samsung flagship series smartphones (S, Note, Z) support DisplayPort Alt Mode technology via a USB-C port. This allows you to transmit video signals directly through the adapter.
You will need a special USB-C to HDMI adapter. One end of the adapter connects to the smartphone, and the second inserts a standard HDMI cable that goes to the Xiaomi TV. After connecting, switch the signal source to the TV to the appropriate port (for example, HDMI 1 or HDMI 2).
| Adapter type | Permit supported | Do you need a sound? | Compatibility |
|---|---|---|---|
| USB-C on HDMI | up to 4K 60 Hz | Yes (via HDMI) | Samsung S/Note/Z Series |
| MHL adapter | up to 1080p | Yes. | Older Samsung models |
| Slimport | up to 1080p | No (needs AUX) | Rare models |
There are virtually no delays when using wired connectivity, making this a perfect method for games or presentations. Some adapters have an additional charging port, allowing you to play games for hours without worrying about the battery drain of your smartphone.
💡
Use HDMI 2.0 or higher cable to support 4K and HDR resolution. Older HDMI 1.4 cables can limit frame rates to 30 Hz at high resolution.
If your smartphone doesn’t support USB-C video output (usually the budget Galaxy A or M series models), the wired method won’t work, so you’ll have to rely solely on wireless technology or purchase a dedicated docking station that supports software broadcasting, although this is rare.
Third-party applications for screen duplication
Embedded tools don’t always work well, especially if devices are in a complex network environment, and in these cases, third-party apps available on the Google Play store come to the rescue. One of the most popular and functional solutions is the Web Video Caster or TV Cast app.
The principle of their work is to install a special receiver application on the Xiaomi TV (via the built-in TV app store) and a transmitter application on the Samsung smartphone. Once launched, both devices find each other over the local network, and these programs often know how to stream video files from the phone’s memory that are not supported by standard means.
- 📥 Install the receiver app on Xiaomi TV (For example, Receiver for Web Video Caster").
- 📲 Download the client application on Samsung Galaxy.
- 🔗 Launch the applications and wait for the connection to IP-address.
- 🎬 Select a file or link to broadcast.
Another powerful tool is the ApowerMirror app, which allows you to not only broadcast the screen, but also control the phone from the TV (if you have a mouse), and take screenshots and record the screen. It may require you to enable debugging over USB at the initial setup stage, but Wi-Fi is enough for wireless operation.
⚠️ Note: Third-party apps may contain ads or require subscriptions to unlock features such as streaming to 1080p or 4K. Free versions often have a session time limit.
Using specialized software also allows you to broadcast audio separately if the TV does not support the audio stream through the standard Miracast.This often solves the problem when the video is going and the sound remains on the phone.
Troubleshooting and troubleshooting
Even with the right setup, there can be technical difficulties. One of the most common problems is that the TV doesn't show up on the list of available devices. First of all, check if the router is insulating access points. Also try rebooting the router, because detection protocols (DLNA, SSDP) sometimes stick.
If the image twitches or is low resolution, try to bring the smartphone closer to the router or TV. Interference from microwave ovens or neighboring Wi-Fi networks can also affect connection stability, especially in the 2.4 GHz band, so switching to 5 GHz often solves the problem.
💡
90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
If the sound is not transmitted to the TV, check the audio output settings in the application itself, from which the broadcast is coming, or in the settings. Bluetooth/Smartphone sound. Sometimes the default system chooses the phone speaker instead of the phone speaker. HDMI-audio.
If nothing works, reset your network settings on your Samsung smartphone, which will remove stored Wi-Fi passwords and Bluetooth settings, but often eliminate deep software conflicts of network modules. After reset, reconnect to Wi-Fi and try to start the broadcast.
