Modern multimedia capabilities make it easy to share content from a mobile device on a large screen. Owners of a bundle of Samsung smartphone and Xiaomi TV often wonder how to organize wireless image transfer. Fortunately, the Android ecosystem on which both devices are based provides several native and third-party tools to solve this problem.
In this article, we will discuss all the current methods of synchronization, from built-in functions to specialized applications. You will learn how to configure Miracast, use DLNA protocols and even connect a gadget through a cable. Understanding the differences between these technologies will help you choose the best option for watching videos, photos or games.
The quality of the connection depends on the stability of your local network. Before you set up, make sure that both devices are connected to the same Wi-Fi network, which is a critical condition for most wireless data protocols.
Device preparation and network verification
The first step should always be to check the network infrastructure. Make sure your router is sending out a signal at 5 GHz, if possible, as it provides higher bandwidth. Samsung Galaxy and Smart TV Xiaomi Mi TV should be in the zone of confident reception.
Go to your TV settings and check the version of your Android TV or PatchWall operating system. Often manufacturers release updates that improve the stability of the Wi-Fi Direct module. The phone also needs to check for system updates by going to the Settings → Software Update menu.
⚠️ Warning: If your router uses customer isolation mode (AP Isolation, devices won't see each other on the network. This option must be disabled in the router settings.
To diagnose the connection speed, you can run a speed test directly on your TV through the Speedtest app. Low speed can lead to image artifacts and audio desynchronization during streaming.
Use the built-in Smart View feature on Samsung
The easiest way to broadcast the screen is to use Samsung’s native Smart View technology, built into its One UI shell, which is based on the Miracast standard, which is supported by most Xiaomi TVs without installing any additional software.
To start the process, lower the notification curtain on your phone and find the Smart View icon. If it's not on the first screen, scroll to the left or click three button editing points. Once activated, the phone will start searching for available displays.
- 📱 Select your Xiaomi TV from the list of found devices.
- 📺 On the TV screen may appear a request for permission to connect – confirm it with the remote.
- 🔄 The image from the phone will instantly appear on the TV in full size.
- ⚙️ To change quality, go to Smart View settings and select Performance Priority.
Importantly, when using Smart View, the phone's screen is completely duplicated, meaning any notifications or incoming calls will be visible on the big screen.The Game Booster mode on Samsung phones can automatically optimize transmission to reduce latency.
☑️ Checking before connection
Broadcasting via Google Home and Chromecast
If the built-in method is unstable, a great solution is to use the Google Cast protocol. Xiaomi TVs often have built-in Chromecast support, which allows you to stream content directly from apps.
Install the Google Home app from the Play Market store on your Samsung smartphone. Once logged in to your Google account, the app will find the TV on the local network. Click on the device icon and select the option to Translate screen.
This method is particularly useful for streaming videos from browsers or apps that don’t have their own casts button. Image quality is often higher than direct screen duplication, as the TV itself loads the data stream.
What to do if Chromecast is not found?
The advantage of using the Google ecosystem is that you can control playback from your phone as if it were a remote control, so you can pause the video, change the volume, or rewind the content without getting up from the couch.
Applications for DLNA and Miracast
In some cases, standard tools may not work properly with certain file formats or codecs, and specialized applications such as TvCast, Web Video Caster, or BubbleUPnP come to the rescue.
These programs use the DLNA protocol to transmit media content, and unlike mirror display, only the video file or photo is broadcasted, saving the battery of the smartphone, the phone acts as a controller, and the TV decodes.
| Annex | Protocol | Support for subtitles | Advertising |
|---|---|---|---|
| Web Video Caster | DLNA / Cast | Yes. | Got it (Free) |
| BubbleUPnP | DLNA / UPnP | Limited. | No. |
| TvCast | Miracast | No. | There is. |
| Xiaomi Mi Remote | Infra-red/Wi-Fi | N/D | No. |
When choosing an app, pay attention to support for H.265 and HEVC codecs, which are often used in modern high-resolution video files. Some players may not play audio through HDMI unless the appropriate settings are configured in the app menu.
💡
Use apps with Background Play to continue listening to music with your phone screen off.
Wired connection via USB-C to HDMI
For maximum image quality and zero latency, a wired connection is best, but there’s an important caveat: not all Samsung smartphones support video output via a USB-C port.
The technology is called MHL or Alt Mode DP. Flagship models of the Galaxy S and Note series usually support this mode, while the budget Galaxy A or M series may not have a video output.
You'll need an adapter. USB-C to HDMI. Connect. HDMI-cable from the adapter to the free port of the Xiaomi TV. Once connected, the phone automatically recognizes the external display and offers modes of operation: mirroring or expanding the screen.
⚠️ Attention: When wired, the phone can heat up quickly.It is recommended to use an adapter with an additional charging port to power the smartphone at the same time.
DeX mode, available on top-of-the-line Samsung models, turns the phone’s interface into a desktop operating system when connected to a TV, allowing you to work with documents or a browser as if you were on a full-fledged computer.
💡
Wired connectivity is the only way to play cloud games or dynamic shooters on a TV without input lag.
Addressing delays and quality issues
A common problem with wireless broadcasting is the desynchronization of audio and video or the appearance of "squares" in an image, which usually indicates a lack of channel bandwidth or interference in the air.
Try lowering the output resolution in your broadcast settings. Instead of 1080p or 4K, choose 720p. This will significantly reduce the load on the network and the phone's processor.
- 📡 Restart the router to reset the cache and select a free channel.
- 🔋 Turn off the power saving on your phone, it may limit the operation of the Wi-Fi module.
- 📶 Close your phone to the router or use a Wi-Fi repeater to amplify the signal.
If the problem persists in only one application, try clearing its cache through the Settings → Apps menu. Sometimes the conflict of versions on the TV and phone is solved by updating a particular player application.
