Connecting Xiaomi devices to Samsung TVs opens up new possibilities for viewing content on a large screen, from streaming video from a gallery to duplicating a smartphone screen for games or presentations. However, not everyone knows that synchronization methods depend on device models, firmware version and even the type of cable used. In this article, we will discuss 5 proven ways to connect, including wireless technologies and wired connections, and also explain how to fix typical errors, for example, when the TV does not see the smartphone or the image is slowing down.
The thing about Xiaomi and Samsung is that both brands use their own ecosystems, Mi Ecosystem and SmartThings, which sometimes create conflicts when you automatically recognize devices, but don't worry, most of the problems are solved by setting up multiple parameters. For example, for wireless broadcasting via Miracast or Smart View, it is important that both devices are connected to the same Wi-Fi network, and for the same purpose, the Wi-Fi network is connected to the same Wi-Fi network. HDMI-You may need an adapter with support MHL or USB-C to HDMI.
If you’ve never connected a gadget to a TV before, start with the simplest method, an HDMI cable, which ensures minimal latency and maximum picture quality. Wireless options are suitable for power users, such as Google Cast (if the TV supports Chromecast) or Samsung’s proprietary Smart View app. Next, we’ll go through each method in detail, specify hardware requirements and give tips on how to optimize the connection.
Connection via HDMI: a reliable wired method
Using an HDMI cable is the most stable way to connect, as it does not depend on Wi-Fi speeds and does not create delays when streaming videos or games. However, there is a nuance here: modern Xiaomi smartphones (for example, Redmi Note 12 or Xiaomi 13) do not have a standard HDMI port, so you will need an adapter.
For USB-C connectors (most models after 2018), a USB-C to HDMI adapter with DisplayPort Alt Mode support is required. Importantly, cheap Chinese adapters often don’t transmit sound or give low resolution. We recommend choosing certified accessories from Anker or Baseus. For older models with Micro-USB (for example, Redmi 4X), a Micro-USB to HDMI (MHL) adapter will suit you, but check if your smartphone supports MHL technology – this information can be found in the specifications.
- 🔌 Step 1 Connect the adapter to your smartphone and then connect it to the TV via cable HDMI.
- 📺 Step 2. On a Samsung TV, select the signal source: press the Source button on the remote and select the port HDMI, cable-wired.
- 📱 Step 3. Xiaomi’s smartphone may automatically request a change in display mode. Select “Duplicate screen” or “Expand screen".
- ⚙️ Step. 4. If the image does not appear, check the screen settings: go to Settings → Display. → Regime. HDMI Choose the optimal resolution (usually) 1920×1080 upon 60 Hz).
The critical point is, if you don't have audio on your TV after you've connected, check if your adapter supports audio transmission. Some cheap models only transmit video, in which case the sound will come from your smartphone, plug your headphones or external acoustics into Xiaomi.

2. Wireless broadcast via Miracast (Screen Mirroring)
Miracast technology allows you to duplicate the screen of your smartphone on your TV without wires, but with some limitations. First, both devices must support this standard. Most Samsung TVs released after 2015 (QLED, CU, AU series) have built-in support for Miracast, and Xiaomi smartphones – starting with MIUI 9. Second, for stable operation, you need a high-speed Wi-Fi network (preferably 5 GHz).
Miracast has the advantage of not relying on the Internet, but it connects directly to Wi-Fi Direct, but there are also downsides: delays in watching video (especially in high resolution) and periodic communication interruptions. For games, this is not the right way to do it, but HDMI is the best way to do it.
⚠️ Note: If your Samsung TV doesn’t find a Xiaomi smartphone through Miracast, try turning off the Power Saving feature in your smartphone’s Wi-Fi settings.This option sometimes blocks background data transfer.
- 📱 Step 1. On Xiaomi smartphone, open Settings → Connections and sharing → Screen broadcast (Cast).
- 🔍 Step 2: Turn on device search. The TV should appear in the list (usually under the model name, for example, Samsung). QN90B).
- 🔗 Step 3. On Samsung TV, go to Settings → General. → External devices → Devices for screen duplication and activate the option.
- 🔄 Step 4: Confirm the connection on both devices. PIN-code, enter it from the TV screen.
| Problem. | Possible cause | Decision |
|---|---|---|
| TV doesn't see a smartphone | Wi-Fi Direct is disabled on TV | Enable Settings → Network → Wi-Fi Direct |
| Image slows down | Weak Wi-Fi signal | Switch to 5GHz network or zoom in on devices |
| No sound. | The wrong audio source is selected on the TV. | Check the settings → Sound → Sound source |
| The connection is breaking. | Active mode of energy saving on Xiaomi | Turn off in Settings → Battery → Power saving mode |
3.Using Smart View (for Samsung TVs with Tizen)
Samsung’s Smart View app allows you to not only duplicate the screen, but also control the TV from your smartphone, stream individual media files (photos, videos, music) and even use the phone as a remote. However, there is a limitation for Xiaomi devices: full support for Smart View is available only on smartphones with Android 10 and later. If you have an older version, try updating the firmware or using alternative methods.
Smart View has the advantage of having a more stable connection over Miracast, and additional features like broadcasting only audio (good for listening to music through TV speakers), but for high-resolution (4K) video artifacts can arise from stream compression, in which case HDMI is better.
- 📥 Step 1: Install the Smart View app from Google Play (unless it’s preinstalled on your Xiaomi).
- 🔍 Step 2: Launch the app and wait for it to find your Samsung TV. Make sure both devices are connected to the same Wi-Fi network.
- 📺 Step 3: You may see a request for confirmation of connection on your TV, you'll agree.
- 🎬 Step 4: Select the content type: “Duplicate screen” or “Translate media file” (e.g., video from a gallery).
Tip: If Smart View doesn’t find the TV, try manually adding the device through the TV. IP-For this, go to Settings on the TV. → General. → About the program and find IP. In the Smart View app, select “Add Manually” and enter this address.
💡
If the video is slowing down, reduce the resolution in the Smart View settings (the “Broadcast Quality” option).
4. Connect via Google Cast (Chromecast)
If your Samsung TV supports Google Cast (like models with built-in Chromecast or connected external Google TV device), you can stream content from Xiaomi smartphone through applications that support this technology, including YouTube, Netflix, Google Photos and many others, the main advantage is minimal latency and support for 4K HDR.
However, there is a caveat: Xiaomi blocks some of the system features of Google Cast in its MIUI firmware. For example, the standard “Translation” button in the notification curtain may not be available. In this case, use applications that have built-in Cast support (for example, YouTube or Google Home).
- 🎥 Step 1: Make sure your TV and smartphone are connected to the same Wi-Fi network.
- 📱 Step 2: Open an app that supports Google Cast (e.g. YouTube).
- 🔗 Step 3. Click on the broadcast icon (usually in the upper right corner) and select your Samsung TV.
- 🎬 Step 4: Start playback – the content will start streaming to the big screen.
⚠️ Note: If you are broadcasting via Google Cast, you can check if it is blocking the device. MIUI background activity of the application. For this, go to Settings → Annexes → Permits → Autostart and enable Autostart for Google Play Services.

5. Alternative methods: DLNA and third-party applications
If none of the above methods work (e.g. you have an old TV without Miracast or Smart View), you can use the technology. DLNA. It allows you to stream media files (photos, videos, music) from your smartphone to your TV via a local network. DLNA-server, and on a Samsung TV - find the device in the list of available sources.
To set up DLNA on Xiaomi:
- Open the Files app (or any file manager).
- Go to the DLNA or Translation section (depending on the MIUI version).
- Activate the "Enable" option DLNA-server".
- On Samsung TV, open Sources → Devices → Your smartphone.
If DLNA is unstable, try third-party apps like BubbleUPnP or LocalCast. They support more formats and have additional broadcast quality settings. For example, LocalCast can manually specify the bitrate of a video to avoid lags.
💡
DLNA is only suitable for media files – you can’t duplicate your smartphone screen through this technology. Use Miracast or HDMI for full mirroring.
6. Solving common problems
Even with the right setup, Xiaomi’s connection to a Samsung TV can malfunction.
- 🔄 The TV can’t see the smartphone through Miracast or Smart View.
- 🎵 The sound comes from a smartphone, not from a TV.
- 🖥️ Problem: Image on TV cropped or not up to resolution.
- 🚫 Problem: When connecting through HDMI smartphone screen goes off.
If none of these things work, check your devices’ compatibility, for example, Samsung’s J series TVs (2016 and older) may not support Miracast for Android 11+ devices, leaving you with HDMI or an external adapter like Google’s Chromecast.
7.Putting the connection for games and videos
If you connect Xiaomi to a TV for gaming (e.g., via Xiaomi Game Turbo) or watching high-resolution video, it’s important to minimize delays and quality losses.
- 🎮 For games: Use only HDMI-Connection – wireless methods give a delay 50-200 If the game supports gamepads, connect the Bluetooth controller directly to the TV.
- 🎥 For the video. 4K: When streaming via Miracast or Smart View, choose permission. 1080p, so 4K It can slow down. 4K HDR use HDMI 2.1.
- 🔋 To save charge: Connect your smartphone to charge during broadcast – wireless methods severely drain the battery (up to 1% per minute when used actively).
Professional advice: If you stream content to your TV frequently, create a separate guest Wi-Fi network on your router specifically for this purpose, which will reduce the load on the main network and reduce the risk of connection breakdowns.
