Connecting Xiaomi devices to Samsung TVs opens up new possibilities for viewing content on the big screen, from streaming videos to games with minimal latency. However, not all methods of connection are equally effective: somewhere you will need additional hardware, and somewhere there are enough built-in features of a smartphone or Smart TV. In this article, we will analyze 5 working methods (including hidden settings), compare them in speed, quality of transmission and compatibility with different models, and also give a checklist for the diagnosis of typical errors.
We will pay special attention to the nuances of ecosystem interaction MIUI Tizen OS — Why, for example, Screen Mirroring on Samsung QLED 2023 may not find the Xiaomi 13 Pro, although both devices support Miracast.You will also learn how to get around manufacturers' restrictions (e.g. locking screen recording through a screen lock). HDMI) What developer settings should be activated for stable sound transmission without delay.
1. Connect via Wi-Fi Direct (Screen Mirroring)
The most versatile, wirelessly-based way to do this is to duplicate the screen over a wireless network. Miracast technology (built into most Xiaomi and Samsung devices after 2016) allows you to broadcast images with a delay of up to 50 ms, which is acceptable for video, but not for games. The main advantage is that you don't need a router: devices connect directly.
How this works in practice:
- 📱 On Xiaomi smartphone: open Settings → Connection and sharing → Screen Transfer (or Cast in the Notification Curtain).
- 📺 On Samsung TV: Go to Source → Screen Mirroring (on the remote button Source).
- 🔄 In the list of available devices, select your TV model (for example, UE55CU8000). Confirm the connection on both screens.
💡
If the TV is not listed, check if Wi-Fi Direct is enabled in the Samsung network settings (Settings → General → Network → Wi-Fi Direct).
Limitations of the method:
- ⚠️ The screen resolution can automatically be reduced to 720p resource-saving.
- ⚠️ Sound is not always transmitted – on some Xiaomi models (for example, Redmi Note 12) you need to separately include the option of Sound Transfer in the Cast menu.
- ⚠️ With a weak signal, artifacts are possible (green stripes, slowing down).
HDMI connection: cable or adapter
For minimal latency (critical for games or watching movies in 4K HDR), it is better to use a wired connection. Modern Xiaomi smartphones (starting with the Mi 10) support image output via a USB-C port, but you will need a USB-C → HDMI adapter with DisplayPort Alt Mode support. Importantly, cheap Chinese adapters often do not transmit sound or limit the resolution to 1080p.
Step-by-step:
- Buy a certified adapter (we recommend the Anker 810 or the original from Xiaomi).
- Connect the adapter to your smartphone and the HDMI cable to the HDMI-IN port on your TV (usually marked as ARC or STB).
- On the TV, select the appropriate signal source (Source → HDMI1/HDMI2).
- On the smartphone in the notification curtain will appear notification HDMI-output is active.
Does your Xiaomi DisplayPort Alt Mode support (model list below)|
Is there a TV port? HDMI supportive CEC (remote-control)|
Have you purchased an adapter with a DisplayLink chip or a Moshi (for example, a DisplayLink chip). 4K)|
Have you turned off the energy-saving mode on your smartphone (may interrupt the connection)

List of Xiaomi smartphones with DisplayPort Alt Mode support:
| Model | Max, permission. | Support for HDR | Notes |
|---|---|---|---|
| Xiaomi 13 Ultra | 4K@60Hz | Yes. | Requires an adapter with a WCH CN3161 chip |
| POCO F5 Pro | 1440p@60Hz | No. | Sound is transmitted only via Bluetooth. |
| Redmi K60 | 1080p@60Hz | No. | We need an externally powered adapter. |
| Xiaomi 12T | 4K@30Hz | Yes. | Support for Dolby Vision |
Important nuance: if after connecting on the TV screen there is a message No signal, try:
- 🔌 Reconnect the cable (sometimes helps to "swing" the connector).
- 📱 Enable the developer mode on the smartphone and activate the debugging option HDMI (Settings → The phone. → Version. MIUI — tap 7 times).
- 🔄 Reboot both devices.
3.Using USB-C → USB (MHL/OTG)
A less popular but working method is to connect via a USB TV port, which requires a USB-C → USB-A cable (or adapter) and support for USB OTG on a smartphone, which is suitable for viewing photos/video, but does not broadcast the screen in real time (file access only).
How to set up:
- Connect your smartphone to USB-TV port (usually marked as USB (5V 1A)).
- On the TV in the Source menu, select USB.
- On the smartphone will be a request to access files – allow (Use as a file) USB-accumulator).
- Through the built-in Samsung file manager (Media or Gallery) open the folders of the smartphone.
What video formats are supported USB-connection?
⚠️ Note: When connecting through USB The smartphone will discharge faster as the TV does not provide enough current to charge.Use a powered Y cable or connect the charger in parallel.
4. Connect via Xiaomi (Mi Box, Mi TV Stick)
If you have a Mi Box S or Mi TV Stick, you can use it as an intermediary to stream content from your smartphone to your Samsung TV, a method that is convenient for streaming (like Disney+ or YouTube in 4K), since the console itself decodes the video without loading the smartphone.
Algorithm of action:
- 📦 Connect the Mi Box to the TV via HDMI And plug it in.
- 🔄 On the TV, select the source of the signal (HDMI1/HDMI2).
- 📱 On Xiaomi, open the Google Home app (or Mi Remote for older models).
- 🔍 In the list of devices, find your console and select the option to Translate the screen.
Advantages of the method:
- ✅ Support 4K HDR and Dolby Atmos (on the Mi Box) 4K).
- ✅ Low latency when viewing IPTV or games through Google Stadia.
- ✅ Voice control (via Google Assistant).
⚠️ Note: Some Samsung TVs (J and K series, 2015–2017 Automatic permission switching may not work. Manually set it in the set-top box settings 1080p@60Hz, avoid screen flickering.
5. Alternative methods: DLNA and third-party applications
If standard methods don't work, you can use DLNA protocols or applications like ApowerMirror, TeamViewer QuickSupport, which are suitable for specific tasks, such as broadcasting presentations or remote technical support.
Example of settings through ApowerMirror:
- Install the app on your smartphone and TV (via Google Play on Samsung TV).
- Connect both devices to the same Wi-Fi network.
- On your smartphone, launch ApowerMirror and select M (Mirror).
- On the TV in the same app, click Accept Connection.
Pros and cons of DLNA:
| Advantages | Deficiencies |
|---|---|
| It works on older models (even without Miracast). | Delay up to 2 seconds |
| Supports playlists | No real-time screen transfer |
| You can stream from a PC. | Requires setting up network folders |
💡
For maximum compatibility, use the LocalCast app – it supports streaming on Samsung TV via DLNA, Chromecast and even over a local network without the Internet.
Solving common problems
Even with the right connection, errors can occur, and here are the typical scenarios and ways to fix them:
Problem 1: The TV doesn’t see the smartphone in the Screen Mirroring device list.
- 🔄 Restart your router (if you use it as an intermediary).
- 📱 On your smartphone, turn off Power Saving and Optimization mode MIUI (Settings → Battery).
- 📺 On the TV, update the firmware (Settings) → Support → Update of the PO).
Problem 2: There is no sound when connecting via HDMI.
- 🔊 Check whether the smartphone settings selected sound output through HDMI (Settings → Sound. → Exit).
- 🔌 Try another one. HDMI-port on the television (for example, HDMI ARC).
- 🔄 If you use an adapter, connect external power to it (some models require additional power). USB-soundport).
Problem 3: Videos slow down or break when broadcasting over Wi-Fi.
- 📶 Switch the router to 5 GHz (less interference).
- 📱 Close background apps on your smartphone (especially messengers and downloaders).
- 📺 On the TV, turn off the game accelerator mode (Settings) → General. → External devices).
