How to display an image from a Xiaomi phone to a Samsung TV

Xiaomi’s modern smartphones have powerful screens, but watching photos, videos or games on a large diagonal often requires a TV connection. Android ecosystem users and Samsung appliance owners often face the question of integrating devices, and fortunately, there are many ways to do this without unnecessary wires.

In this article, we will take a closer look at all current broadcasting methods, from built-in system functions to third-party applications, learn how to configure Miracast, use proprietary utilities, and what nuances to consider when wirelessly connecting to achieve the best picture quality.

Synchronizing gadgets from different brands has ceased to be a problem thanks to the development of wireless data standards, just so that both devices are on the same network, and you can instantly show content on the big screen, turning your smartphone into a universal media control panel.

Use of the built-in Translation function in MIUI

The easiest and fastest way to do this without additional software is to use the Translation (or Cast) system function, which is built into the MIUI and HyperOS shell and is based on the Miracast protocol that most modern Smart TVs, including Samsung models, support.

To start the process, you need to make sure your Samsung TV is on and connected to the same Wi-Fi network as your smartphone. Then lower the notification curtain on your phone and find the Broadcast icon. If it's not on the home screen, click on three dots or the pencil icon to edit the menu and add this switch.

Once activated, the phone will start looking for available devices. Your Samsung TV should appear on the list. Click on it, and in a few seconds, the image from the smartphone screen will appear on the TV. It's important to note that this mode broadcasts everything that happens on the phone screen, including notifications and system sounds.

• 📱 Make sure your Samsung TV has a wireless signal reception feature enabled (sometimes called Screen Mirroring or Smart View in the signal source menu).
• 📶 Both devices should be connected to the same Wi-Fi frequency (preferably 5GHz to reduce latency).
• ⚙️ On some Xiaomi models, the feature may be called a “Wireless Monitor».
• 🔄 If the connection fails, try restarting the router and both devices.

⚠️ Note: When using the Translation method, the phone screen must be turned on. If the screen goes out or the phone is blocked, the broadcast may be interrupted or the image remains static.

The quality of the image you transmit depends on the power of your Wi-Fi router and the distance to it. The Miracast protocol creates a direct connection between devices, bypassing the Internet channel, but uses the local network for handshake procedures. If you see audio and video desynchronization, try to reduce the resolution of the output image in the broadcast settings.

Broadcasting through Samsung SmartThings app

Samsung owners have access to a powerful management tool, the SmartThings app, which not only allows you to manage a smart home, but also effectively display content from Android smartphones, including Xiaomi, to your TV.

To get started, download the SmartThings app from Google Play Store to your Xiaomi phone. After installation, launch the program and log in to your Samsung Account (if not, you will need to register).

Select your TV from the device list. In the control menu that opens, look for the Broadcast (or Smart View) button. The system will request permission to connect — confirm it on the TV remote if a notification appears on the screen. This method often works more stable than standard Miracast, because it uses optimized data exchange protocols.

The key to this is that you can control your TV directly from your smartphone screen, you can use your phone as a touchpad, you can type text from your keyboard, you can switch channels without cutting off content, which is especially useful if your remote control is lost or your batteries are running out.

Use of YouTube and streaming services

If your primary goal is to watch videos from YouTube, Netflix or other streaming services, then using the full-screen Translation feature is not the optimal solution, in which case it is much more effective to use the built-in Google Cast (Chromecast built-in) protocol.

The algorithm is simple: open an app like YouTube on a Xiaomi phone. Find the video you want to watch. In the upper right corner of the video player, click on the wave rectangle icon. In the list that appears, select your Samsung TV.

Unlike a full mirror, the phone is only a remote control, and the video is buffered and played directly from the Internet by the TV itself, ensuring maximum picture quality (up to 4K) and no delays, while the phone screen can be used for other tasks or even blocked.

• 🎬 Video quality is automatically adjusted depending on the speed of the Internet.
• 🔋 This method saves smartphone battery life significantly, as it does not encode the video stream.
• 🌐 The TV must have access to the internet because it downloads content.
• 📺 Not only YouTube, but many other apps with the Cast logo are supported.

⚠️ Note: Google Cast will not work if the phone is using mobile internet and the TV is connected to Wi-Fi, or if they are on different subnets (guest network).

It's important to understand the difference between Miracast and Google Cast. The first one copies pixels from the phone screen, requiring constant activity of the smartphone processor; the second one only sends a command to the TV to "enable this video on the link." For watching movies, the second option is always preferable.

Third-party broadcast apps: TV Cast and AirScreen

In situations where built-in methods don’t work or advanced features are required (such as streaming files in certain formats that the TV doesn’t read), third-party apps come to the rescue, with TV Cast for Samsung TV and AirScreen leading the way.

TV Cast allows you to stream not only videos, but also photos, music, and web pages. It works like a browser: you open a site with video inside the app, and it streams to the TV, which bypasses the limitations of some websites that block the standard Cast button.

On the other hand, AirScreen (which you need to install on your TV if it runs on Tizen with third-party apps, or use its Android version on consoles) allows you to implement the AirPlay protocol on Samsung devices. This is ideal if you are used to the Apple ecosystem or if the standard Miracast on Xiaomi is unstable.

Wired connection via USB-C to HDMI

Wireless technology is convenient, but it doesn’t always guarantee stability, especially in networks with a lot of interference. If you want the perfect picture without delay (for example, for games) or no Wi-Fi, the only sure solution is a wired connection.

To implement this method, you will need a special USB-C to HDMI adapter. It is important to note that not all Xiaomi smartphones support video output through the charging port. This feature (DisplayPort Alt Mode) is usually only available on flagship models of the Mi series, Xiaomi (digital series) and some Redmi K models.

Connect the adapter to your smartphone, and it has an HDMI cable going to your Samsung TV. Switch the signal source on your TV to the appropriate HDMI port. The image will appear automatically. Unlike wireless methods, there is no data compression, which ensures that the signal is transmitted in its original quality.

• ⚡ Adapter may require additional power – connect charging to the port USB-C adapter.
• 🎮 Ideal for gaming, as input lag is minimal.
• 🔌 Make sure the cable is HDMI Supports a standard of at least 1.4 for Full HD 2.0 for 4K.
• 📱 The phone screen may go out according to the lock timer, but the video will continue to go on TV.

⚠️ Note: Xiaomi budget models (Redmi Note, Mi A, Lite series) most often do not have a video output through the phone. USB-C. In this case, the adapter will not work and you will have to use only Wi-Fi methods.

When using the cable, the phone can go to DeX-like interface mode (if supported by the manufacturer) or simply duplicate the screen. For games, this is the best option, since it eliminates connection breaks and compression artifacts characteristic of wireless transmission.

Solving problems and adjusting image quality

Even with the right setup, users can experience problems such as a black screen, no sound, or low resolution, most often due to router settings or software versions.

Check if the router is enabled with AP Isolation, which prevents devices connected to Wi-Fi from seeing each other, making it impossible for the phone to detect the TV. Also make sure that the antivirus or firewall on the Xiaomi smartphone does not block local connections.

If you have an image but it is stretched or has black fields, change the aspect ratio in the Samsung TV settings. Press the P.SIZE button on the remote or go to Settings → Image → Aspect Ratio and select “Original” or “16:9”.

💡

To reduce game delay, turn on the Samsung TV's Game Mode in the image settings, which will turn off the extra post-processing of the picture and speed up the response.

In some cases, resetting network settings on both devices helps. On a Samsung TV, this is done via Settings. → General. → Network → Reset network settings. On a Xiaomi phone, you can forget your Wi-Fi network and reconnect, which clears the network cache and eliminates conflicts. IP-address.

💡

Connection stability is 90% dependent on the quality of the Wi-Fi signal and the absence of interference in the air, so 5 GHz is always preferred for 4K content.
