You want to watch movies, photos or streams from your smartphone screen on a big screen of a Xiaomi TV, but don’t know how to do it correctly? This article will help you choose the best way to connect depending on your tasks – whether it’s watching. 4K-We'll go through all the current techniques, from wireless technology to wired solutions, and we'll also talk about how to avoid typical problems like latency or low resolution.
Xiaomi TVs (Mi series) TV A Pro, Mi TV Q2, Redmi Smart TV And others support most of today's standards for content transmission, but not all of them are equally convenient. For example, Miracast can slow down when there's a weak Wi-Fi signal, and it can slow down. HDMI-cable will require an adapter for new smartphones without a microUSB connector. In this instruction, you will find not only step-by-step guides, but also a comparative table of methods indicating maximum resolution, latency and compatibility with TV models.
1. Wireless connection via Miracast (Screen Mirroring)
Miracast technology allows you to duplicate a smartphone screen on a Xiaomi TV wirelessly using direct Wi-Fi Direct. This method works on most Android 4.2+ devices and does not require a router — enough for both devices to support the standard. However, there are nuances: some applications (such as Netflix or YouTube) can block broadcasting due to copyright protection.
To connect:
- 📱 On your smartphone: open Settings → Connections → Screen Mirroring (or Screen Mirroring depending on the firmware).
- 📺 On Xiaomi TV: Go to Settings → Connection and sharing → Wireless broadcast and turn on standby mode.
- 🔍 In the list of available devices on your phone, select the name of your TV (for example, MiTV-AB1234).
- ✅ Confirm the connection on both devices.
If the screen is not duplicated or the image is slowing down, check:
- 📶 Signal quality: walls and distances greater than 5 meters can impair communication.
- 🔄 Restart both devices – sometimes resetting the Wi-Fi module helps.
- 📱 Turn off the power saving mode for Screen Mirroring.
💡
If Miracast doesn’t work on Xiaomi with MIUI 14+ firmware, try turning on developer mode and activating the Wi-Fi debugging option in your TV settings.
⚠️ Note: When using Miracast on Xiaomi TVs older than 2019, there may be a delay of up to 200 ms. For games or videos with synchronous sound, it is better to use HDMI or Google Cast.
2. HDMI connection: maximum quality without lags
The wired method over HDMI ensures stable video transmission in resolution up to 4K@60Hz without delay.This is ideal for watching high-quality movies or streaming games from your phone. However, modern smartphones (for example, Xiaomi 13 Pro or Redmi Note 12) do not have a microHDMI port, so you will need an adapter:
- 🔌 USB-C → HDMI (cellphone USB Type-C, for example, Poco F5).
- 🔌 MicroUSB → HDMI (For older models like Redmi 5).
- 🔌 Lightning → HDMI (If you have an iPhone, but that’s not the topic of the article).
Step-by-step:
- Connect the adapter to the smartphone, and HDMI-cable to Xiaomi TV (the port is usually signed) HDMI 1/ARC).
- On the TV, select the appropriate signal source (Source or Input button on the remote).
- The phone may need to be on mode. USB-debugging or selecting the type of connection Transfer images (MHL).
If the image does not appear:
- 🔋 Check if your adapter supports you. MHL (Mobile High-Definition Link – without it, video transmission will not work.
- 🔄 Try another one. HDMI-cable (cheap cables may not be used) 4K).
- 📱 Update the phone firmware – in older versions MIUI There were bugs with the output through HDMI.

The phone is allowed to transfer mode by USB-->
| Connection method | Max, permission. | Delay. | Internet is required | Compatibility with Xiaomi |
|---|---|---|---|---|
| Miracast (Screen Mirroring) | 1080p@30Hz | 100-300 ms. | No. | All models with Android TV |
| HDMI (wired) | 4K@60Hz | 0 ms. | No. | Adapter required |
| Google Cast (Chromecast) | 1080p@60Hz | 50-150 ms. | Yeah (Wi-Fi) | Models with built-in Cast |
| USB (MTP/PTP) | 1080p | No broadcast. | No. | Photo/video only |
| DLNA (media server) | Depends on the file. | 200-500 ms. | Yeah (Wi-Fi) | All models. |
3. Broadcast via Google Cast (Chromecast)
If your Xiaomi TV supports Google Cast (built-in feature or via Mi TV Stick), you can stream content from supported apps (YouTube, Google Photos, Netflix, etc.) without duplication of the entire screen.
How to set up:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- Open an app that supports Cast (like YouTube).
- Slip on the broadcast icon (📡) Choose your Xiaomi TV from the list.
- Start playing – the video will be broadcast directly to TV.
If the Cast is not working:
- 🔄 Restart your router – sometimes changing your Wi-Fi channel (for example, from 2.4 GHz to 5 GHz) helps).
- 📱 Update the application from which the broadcast is being conducted.
- 📺 On the TV, check if Google Cast is enabled in your network settings.
What apps support Google Cast?
⚠️ Note: On Xiaomi TVs with PatchWall firmware (e.g. Mi) TV 4S) Cast may conflict with the built-in Miracast, in which case, disable Miracast in the settings before using Google Cast.
4. USB connection: viewing photos and videos without broadcasting
If you just need to show photos or videos from your phone on a Xiaomi TV, but don’t need screen duplication, you can use it. USB-cable-wire (MTP or PTP). This method is not suitable for streaming or gaming, but is convenient for viewing pre-downloaded files.
Instructions:
- Connect your phone to your TV with a USB-A → USB-C/MicroUSB cable (depending on the TV connector).
- On your phone, select File Transfer (or MTP) mode in the connection notification.
- On the TV, open the Files app or Media Player and select the connected phone.
Limitations of the method:
- 🎬 No reproduction is supported DRM-Protected videos (for example, downloaded from Netflix).
- 📂 The phone's file system should be FAT32 exFAT (NTFS unsupported).
- 🔋 The phone will be discharged faster due to constant data transfer.
If the TV can't see the phone:
- 🔌 Try another one. USB-cable (not all cables support data transmission).
- 📱 Turn on the phone mode Debugging on USB developer-setting.
- 📺 Update the TV firmware – older versions of PatchWall had bugs with the USB-connection.
5. Using DLNA to Transfer Media Files
DLNA (Digital Living Network Alliance) allows you to stream videos, music and photos from your phone to your Xiaomi TV over a local network. Unlike Miracast, it doesn't duplicate screens, it only transfers media files. This method is convenient for home collections, but not suitable for streaming services.
How to set up:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- On the phone, install a media server application, such as BubbleUPnP or VLC.
- In the app, select files to broadcast and specify the Xiaomi TV as a playback device.
- On the TV, open the Media Player app or DLNA-browser.
Challenges and solutions:
- 🎵 Do some video formats not play? Install a Kodi TV or VLC Android TV — They support more codecs.
- 📶 Reduce bitrate in media server settings or switch to 5 GHz Wi-Fi.
- 🔍 Does the TV see the phone? DLNA-server.
💡
DLNA is suitable for local files, but does not replace Miracast or HDMI for streaming, the main advantage is the low load on the phone and the ability to play back in the background.
6. Solving typical connection problems
Even after you set it up correctly, you can still get errors, and here are the most common ones and how to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| No sound when broadcasting | The phone has a different sound source. | In the phone notification panel, select TV as the output device |
| Image slows down | Weak Wi-Fi signal or high network load | Switch to 5 GHz, disconnect other devices from the network |
| TV can't see the phone | Wi-Fi Direct or Miracast is disabled on TV | Restart both devices and turn on modes manually |
| Low resolution at HDMI | The cable or adapter does not support 4K | Use a certified HDMI 2.0 cable |
| Sound delay | Unsynchronized audio and video streams | In the settings of the TV, turn on Lipsinc (lip synchronization) |
If none of the methods work, check:
- 📋 Compatibility of your Xiaomi TV model with the chosen connection method (e.g. Mi) TV 4A Does not support Miracast on some firmware).
- 🔧 Availability of firmware updates for TV and phone.
- 🛠️ Integrity of cables and adapters (damaged wires can cause image artifacts).
7. Which way to choose: comparison by task
The choice of the connection method depends on your goals:
- 🎮 For games: only HDMI (Minimum latency or Miracast (if the game supports wireless mode).
- 🎥 For the movies in 4K: HDMI Google Cast (if the app supports the app) 4K).
- 📷 For photo and local video: USB or DLNA.
- 📱 For screen duplication (social networks, presentations): Miracast.
For owners of Xiaomi TVs with Android TV (such as Mi TV Q1), the best option is Google Cast – it is integrated into the system and supports most streaming services. If you have a model with PatchWall (such as Redmi Smart TV X), check for built-in Miracast in the settings.
💡
For stable high-resolution video broadcasting, wired methods (HDMI) are the priority. Wireless technologies (Miracast, Cast) are more convenient, but depend on the quality of the network.
