Screen Synchronization: Why Itโs Comfortable
Connecting a Xiaomi smartphone to a TV of the same brand opens up possibilities that many users do not even know about. Imagine: you watch YouTube videos on the subway, come home โ and after a couple of clicks continue to watch on the big screen without loss of quality. Or play a mobile game, but want to transfer the gameplay to a 55-inch display with support for 4K@60Hz. Or maybe you need to urgently show photos from vacation to relatives gathered at the TV.
Xiaomi has specifically optimized the interaction between its devices: Mi TVs, Redmi TVs and Xiaomi TV A Pro support proprietary wireless protocols that are faster and more stable than standard solutions. For example, Xiaomiโs Miracast technology is adapted to the MIUI ecosystem, which reduces broadcast delays to 30-50 ms โ critical for games or video chat. But even if you have an old model of a TV without MIUI TV, there are always backup options for connecting via cables or universal protocols.
In this article, we will discuss 5 proven synchronization methods, including nuances for specific phone models (Xiaomi 13 Pro, Redmi Note 12, POCO F5) and TVs (Mi TV Q2, Redmi Smart TV X55).
1. Wireless connection via Miracast (fastest way)
Miracast is a wireless image standard that Xiaomi has developed for its devices, allowing you to duplicate the screen of your smartphone on your TV without wires, while the sound is transmitted synchronously, the main advantage over Chrome Cast or DLNA is that there is no dependence on the Internet connection: devices communicate directly via the Wi-Fi Direct protocol.
To activate Miracast on your Xiaomi TV, follow the steps:
- Turn on the TV and go to Settings โ Connections โ Wireless display.
- Activate the Miracast option (some models may call it Screen Mirroring).
- On a Xiaomi smartphone, open Settings โ Connection and Sharing โ Transfer to the screen.
- In the list of available devices, select the name of your TV (e.g. MiTV-Q2-1234).
If the connection is not established, check:
- ๐ Both devices are connected to the same Wi-Fi network (even if you use Wi-Fi Direct, sometimes you need a shared network for initial synchronization).
- ๐ฑ The phone has enabled the mode Do not interrupt transmission (in Miracast settings).
- ๐ Charge level of the phone above 20% โ at low charge, the system can block resource-intensive functions.

โ ๏ธ Note: On Xiaomi TVs with firmware older MIUI TV 3.0 may not support Miracast as usual. WFD (Wireless Display in the Settings menu โ Additionally.
Connection via HDMI (maximum quality and stability)
If you need to stream an image in 4K HDR resolution or play mobile games without delay, wired HDMI is the best choice.
- ๐ฑ Xiaomi Smartphone with Support USB-C (All models after 2019).
- ๐ Cable USB-C โ HDMI (adapter USB-C โ HDMI + standard HDMI-cable).
- ๐บ Xiaomi TV with a free port HDMI 2.0 or newer (for) 4K@60Hz).
Instructions for connection:
- Connect the cable to the USB-C port on your phone and to the HDMI port on your TV.
- On the TV, select the signal source - appropriate HDMI-port, HDMI 1).
- On the smartphone may appear a request for permission to transfer the image โ confirm it.
Advantages of this method:
- ๐ฎ Input lag (less than 10 ms) is ideal for gaming.
- ๐ Support for all permissions and formats HDR, Which is what your TV allows.
- ๐ No battery consumption for wireless transmission (relevant for long sessions).
| Model phone | Max. HDMI resolution. | Support for HDR | Notes |
|---|---|---|---|
| Xiaomi 13 Ultra | 4K@60Hz | Yes (HDR10+) | Cable with DisplayPort Alt Mode support |
| Redmi Note 12 Pro+ | 1080p@60Hz | No. | Maximum via adapter - FHD |
| POCO F5 | 2K@60Hz | Yes (HDR10) | Supports Dolby Vision when manually enabled |
| Xiaomi 12T | 4K@30Hz | Yes. | 60Hz requires an active adapter |
โ ๏ธ Warning: If after connecting the image on the Xiaomi TV is displayed with artifacts or "strips", check the cable for compliance with the standard HDMI 2.0. Cheap adapters often support only the HDMI 1.4, limiting the authorisation to 1080p@30Hz.

3. USB transmission (for charging and transferring files)
A lesser known but useful way is to connect your phone to a Xiaomi TV via a phone. USB-This method doesn't broadcast the screen, but it does:
- ๐ View photos/video from your phone on a large screen through the TVโs built-in file manager.
- ๐ Charge your phone while watching (if the TV supports) USB OTG nourished).
- ๐ต Playing music through TV speakers.
How it works:
- Connect your phone to a USB port on your TV using a USB-C โ USB-A cable.
- On the phone screen, select the Connection Mode โ File Transfer (MTP).
- On the TV, open the Media Player or Files app and select the connected device.
Limitations of the method:
- โ No screen duplication, only access to files.
- โ Not all Xiaomi TVs are supported MTP (Like Redmi. TV A55 requires firmware updates).
- โก When Playing High-Resolution Video (4K) Lags can occur due to restrictions USB 2.0.

If the TV can't see the phone through USB, try turning on the developer mode on your smartphone and activating the USB debugging option. Sometimes this helps initialize the connection.
4.Use of the Mi Home app (for smart management)
If you have a Xiaomi TV with support for the Mi Home ecosystem (for example, Mi TV Q1E or Xiaomi TV A Pro), you can use the proprietary application for advanced control.
- ๐บ Control your TV from your smartphone as a remote control (including voice commands).
- ๐ Transmit links to videos from YouTube or Netflix directly to the big screen.
- ๐ฑ Use your phone as a touchpad to navigate MIUI TV.
Step-by-step:
- Install the Mi Home app on your phone and log in to your Xiaomi account.
- Add the TV to the list of devices through Add the device โ TVs.
- Confirm the pairing on the TV (enter the code that will appear on the screen).
- From the device menu in Mi Home, select Screen Management.
Important: To fully work Screen Share function through Mi Home, both devices must be connected to the same Wi-Fi network and have the latest firmware version. On TVs with MIUI TV 4.0 and later, the option is available Fast Transfer, which speeds up data exchange by 2 times.
5. Alternative methods: DLNA and Google Cast
If standard methods do not work (for example, on older TV models), you can use universal protocols:
๐น DLNA (multimedia)
The DLNA protocol allows you to stream videos, music and photos from your phone to your TV without duplicating the screen.
- On the TV, activate DLNA in the network settings.
- On the phone, install a media server application (for example, BubbleUPnP).
- Select files to play and specify the TV as the target device.
๐น Google Cast (for streaming)
If you have a Google TV or YouTube app installed on your TV, you can use Google Cast:

Limitations:
- โ DLNA does not transmit sound in Dolby Atmos format or DTS:X.
- โ Google Cast does not work with all apps (for example, TikTok does not support live streaming).

Common Problems and Their Solutions
Even with the right connection, there can be failures, and here are the typical situations and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| TV doesn't see phone on Miracast | Different versions of firmware | Update both devices via Settings โ About Phone/About TV โ System Update |
| Sound is transmitted, but the image is not. | Limitations of HDCP | Use the original HDMI cable with HDCP 2.2 support |
| Delay in play (lag) | Wi-Fi network overload | Switch to 5 GHz or use HDMI |
| Mi Home app doesn't find TV | Firewall locking | In router settings, allow multicast traffic for the local network |
If none of these methods work, check:
- ๐ On the TV, the mode Allow external devices to connect (Settings) is enabled โ Security).
- ๐ถ Turn it off. VPN On the phone, it can block local connections.
- ๐ Restart both devices (sometimes cache resetting helps) MIUI through settings โ Annexes โ Application management โ Cash).
