Modern users often face the need to bring the contents of the smartphone screen to a large diagonal, especially when it comes to viewing photos or videos. Owners of the Android ecosystem and Samsung TVs may be difficult due to the lack of a single standard, such as Apple’s AirPlay. However, broadcasting the screen from Xiaomi to Samsung Smart TV is quite possible and implemented by several proven methods.
The basis for a successful connection is a local Wi-Fi network to which both devices must be connected. Without a shared router, high-quality wireless data transmission is impossible, so the first step should always be to check the connection. In some cases, especially with older TV models, physical cables or special adapters may be required.
In this article, we will take a closer look at MiUI and HyperOS, third-party apps and wired solutions, how to configure Miracast or DLNA to enjoy content without delay, and look at common sync errors and how to fix them.
Preparing devices for wireless synchronization
Before you start setting up software interfaces, you need to make sure that devices are physically accessible to each other within the network. Make sure your Smart TV is connected to the Internet and your Xiaomi smartphone is in the zone of confident reception. The distance between the router and the TV should not be critical, since the data flow requires stable channel bandwidth.
Samsung TVs often require you to activate the standby mode. Go to the TV settings menu, search the Shared or Network section and make sure that external request is enabled. In modern models, this happens automatically, but on series devices until 2018, you may need to manually start the Screen Mirroring app or similar service.
⚠️ Note: If your router supports dual-band (2.4 GHz and 5 GHz), try to connect both devices to the same frequency. Different frequencies can create virtual network partitioning, which means that devices simply “can’t see” each other.
Check the version of the operating system on your smartphone. For proper multimedia protocols, you need to have up-to-date Android updates and MIUI shell. Outdated software may not support the new encryption standards used by Samsung TVs.
Use of the built-in Translation function in MIUI and HyperOS
The easiest and fastest way to do this without having to install any additional software is to use a system utility, which is called Translation or Wireless display in Xiaomi’s shells, which is based on Miracast technology, which allows you to transmit images in real time with minimal latency.
To start the function, lower the notification curtain and find the Translation icon. If it is not in the visible part of the panel, click on the edit button (usually a pencil icon or three dots) and drag the icon to the active menu. After clicking, the smartphone will begin to search for available devices on the network.
- 📱 Open the control center on the Xiaomi smartphone swipe down.
- 📺 Make sure that the Samsung TV is on and on standby.
- 🔍 Click on the Translation icon and wait for your TV name to appear in the list.
- ✅ Select the TV to start mirroring the screen.
Once connected, the image from your smartphone will appear on your TV screen, the quality of the image depends on the power of the Wi-Fi router. If you notice a desynchronization of sound and video or twitching of the image, try to approach the router or turn off other devices that consume traffic.
Broadcasting through Samsung Smart View
Although Samsung has officially stopped supporting a separate Smart View app for Android, its functionality has been integrated into standard system tools and SmartThings service. However, for older TV models or specific use cases, Xiaomi owners can use alternative clients that support the DLNA protocol or Samsung proprietary extensions.
A more relevant solution is to use the SmartThings app, which is officially supported by Samsung, and by installing it from Google Play on a Xiaomi smartphone, you get access to TV control and Mirror Display, which allows you not only to duplicate the screen, but also to use the phone as a remote.
The setup process in SmartThings is as follows: launch the app, click Add Device, and the system will automatically find the TV on the network. After pairing (the confirmation code may appear on the TV screen), select the mirror option, which often works more stable than the standard Miracast, because it uses optimized compression algorithms.
☑️ Check before connecting SmartThings
It is worth noting that when using third-party or official Samsung applications on Xiaomi, the system can request additional permissions to access the local network and microphone, which is necessary for voice control and audio streaming.
Application of third-party repetitive applications
In situations where standard methods don’t work or the TV doesn’t have a built-in Smart TV (models up to 2015-2016), universal repetitive apps come to the rescue, with AirScreen, the leader in this niche, which can be installed directly on a Samsung TV through the Tizen Store app store.
The principle is that the app turns the TV into a receiver emulating the AirPlay, Google Cast and Miracast protocols. Once you install AirScreen on your TV, launch it and press "Start." Now your Xiaomi will see the TV as a native broadcast device.
| Annex | Type of protocol | Platform TV | Advertising |
|---|---|---|---|
| AirScreen | AirPlay, Cast, Miracast | Tizen (Samsung) | Available (in the free version) |
| Cast to TV | DLNA, Cast | Tizen, WebOS | There is. |
| Web Video Caster | DLNA, HTTP | Any (via browser) | No. |
| Smart View (Legacy) | Proprietary | Android (on TV) | No. |
Another popular option is the Web Video Caster app, which is interesting because it doesn't allow you to stream the entire screen, but a specific video from a browser or file manager. You open the video on your phone, you choose the playback device (your Samsung), and the video starts to go directly from the Internet to the TV without loading the smartphone.
⚠️ Note: Free versions of repetitive apps may display a banner ad or periodic pop-ups on the TV screen. For continuous use, it is recommended to purchase premium access within the application.
Wired connection via HDMI and adapters
When wireless is unstable or requires maximum image quality (4K HDR) without compression, the only correct solution is cable. Xiaomi smartphones with USB Type-C port support video output, but the availability of this feature depends on the specific processor model and interface version.
To connect, you will need a USB Type-C to HDMI adapter. It is important to understand that not all Xiaomi phones support video output via USB. The flagship models of the Mi series, Xiaomi (digital series) and some Redmi Note (Pro versions) models usually have this capability thanks to support for the MHL standard or DisplayPort Alt Mode.
Checking video output support:
1. Connect the adapter to the phone.
2 Connect the HDMI cable from the adapter to the TV.
3. switch the signal source to the TV to the appropriate HDMI port.
4 If the phone supports output, the image will appear automatically.If nothing happens after you connect, your specific USB-C port will likely only support data transfer and charging, not video, in which case software methods (described above) remain the only options.
Why is cable better for gaming?
Broadcasting multimedia: YouTube and online cinemas
The video service app broadcasts are particularly noteworthy, using Google Cast (Chromecast built-in) technology, which works differently than a simple screen mirror, the TV uploads the video stream itself, and the smartphone acts only as a remote control.
In YouTube, Netflix, Kinopoisk or IVR apps, you need to find a stream icon (a rectangle with waves in the corner). Click on it, select your Samsung TV. The advantage of this method is that you can fold the app, answer a call or go online, and play on the TV will not be interrupted.
- 🎬 Open the video in the application on the Xiaomi smartphone.
- 📡 Click on the “Translation” icon in the player.
- 📺 Select a Samsung TV from the list of devices.
- ▶️ Replay control is available from the phone.
The image quality is often higher than Miracast, as the TV takes the stream directly from the network in the maximum bitrate available, and the smartphone battery is consumed much more economically, since the phone screen can be extinguished.
💡
If video slows down when streaming via YouTube, try to reduce the quality in the settings of the video on the TV (for example, from 4K to 1080p). Often the problem lies not in the speed of the Internet, but in the power of the TV processor, which does not have time to decode the heavy stream.
Solving Connection Problems and Errors
Despite the fact that technology is fine, users can encounter errors, and the most common problem is "Device not found." 90% of the time, this is solved by rebooting the router. Routers tend to accumulate errors in the ARP table, which causes them to stop correctly routing packets between devices within the local network.
Another common situation is that there is an image, but there is no sound. Check the audio settings in Xiaomi's Quick Setup menu. Sometimes when you connect an external display, the default sound stays on the phone. Also make sure that the TV doesn't activate Quiet Sound mode or select the wrong audio source.
⚠️ Note: If the image is constantly scattering into pixels when broadcasting over Wi-Fi, try temporarily disabling Bluetooth on your smartphone. In some cases, Wi-Fi and Bluetooth modules interfere with each other, working in adjacent frequency bands.
In case neither of these methods works, it makes sense to reset the network settings on both devices. On Xiaomi, this is done via Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. On a Samsung TV, you can reset the network settings in the corresponding menu section.
💡
Transmission stability is 80% dependent on the quality of the Wi-Fi router. If you have an older router (802.11n or lower), switching to a dual-band router (802.11ac/ax) will solve most buffering and delay problems.
