Wirelessly streaming a smartphone screen to the big screen has become an integral part of the modern multimedia experience. Miracast technology allows you to transmit images and sound wirelessly using the Wi-Fi Direct standard. Owners of Xiaomi devices โ both smartphones and TVs โ often face the question: how to properly activate this feature and avoid typical connection errors?
In this article, we will not only look at basic Miracast settings across Xiaomi models, but also compatibility nuances, alternative protocols (like Google Cast), and ways to fix common problems. We will focus on the differences between MIUIs and Mi TVs, where the switching algorithm may differ significantly, and if you tried to connect but the screen is black or the connection is constantly breaking, here you will find solutions.
What is Miracast and why is it better than other technologies?
Miracast is a wireless screen broadcast standard developed by the Wi-Fi Alliance, which works on most devices without branding, unlike proprietary solutions like Apple AirPlay.
- ๐ Low latency โ ideal for gaming and video (up to 50ms in optimal conditions).
- ๐ถ Direct connection via Wi-Fi Direct, without depending on the router.
- ๐ฎ Full support HD 5.1 sound (on compatible devices).
- ๐ Without the need for the Internet โ works in autonomous mode.
On Xiaomi devices, Miracast is integrated into the system as part of the Wireless Display feature (or Wireless Display in global firmware).However, not all models support it equally well. For example, smartphones on MIUI 12 and later can automatically switch to Google Cast if Miracast is not available, which sometimes confuses users.
It's important to understand that Miracast is not the same as DLNA or Chromecast. The former broadcasts the entire screen of the device in real time, whereas DLNA only transfers media files, and Chromecast requires support from the application. If you need to duplicate the screen of the smartphone on the Xiaomi TV without lags, Miracast will be the best choice.
Checking the compatibility of Xiaomi devices with Miracast
Before you try to turn on Miracast, make sure your devices support this technology. Below is a compatibility table of popular Xiaomi models:
| Type of device | Model | Miracast support | Notes |
|---|---|---|---|
| Smartphones | Xiaomi 13/13 Pro, 12/12 Pro, 11/11 Pro | โ Yes. | It requires MIUI 12 and newer. There are some bugs with sound on MIUI 13. |
| Smartphones | Redmi Note 11/12, POCO F4/F5 | โ Yes. | In global firmware, the function may be called Cast. |
| Televisions | Mi TV Q2/Q1E, Mi TV A2 | โ Yes. | Miracast and DLNA support. On the menu, look for Wireless. |
| Televisions | Mi TV 4S/4A (2018โ2020) | โ ๏ธ Partially. | You need to update the firmware. You can have lags on older versions. |
| Tablets | Xiaomi Pad 5/6 | โ Yes. | The best compatibility among Xiaomi tablets. |
If your model is not in the table, check Miracast support through the settings:
- On your smartphone: go to Settings โ Connections and Sharing โ Wireless display.
- On TV: Settings โ Network and Access โ Miracast (or Screen Mirroring).
โ ๏ธ Note: MediaTek-based devices (e.g. Redmi) 9A or POCO M3) Miracast may have problems due to the limitations of the chipset, and in such cases it is recommended to use alternative methods, such as Google Cast through the Google Home app.
Step-by-step: how to turn on Miracast on Xiaomi smartphone
The Miracast activation algorithm on Xiaomi smartphones depends on the version of MIUI. Below is a universal instruction, suitable for most models on MIUI 12-14:
Make sure that Wi-Fi and Bluetooth are enabled
Connect both devices to the same network (optional)
Close the background applications for stability
Check the battery charge (minimum 30%)-->
- Open the wireless display settings: Go to Settings โ Connections and Sharing โ Wireless Display. On some firmware, the path may differ: Settings โ Screen โ Wireless screen.
- Activate Device Search: Click on Wireless Display (or Cast in global versions) and the smartphone will start scanning the available screens.
- Select your target device: The name of your TV or Miracast adapter (e.g. Mi TV Q2-75) will appear on the list.
- Confirm Connection: A confirmation request may appear on your TV. On your smartphone, select Start broadcast.
If the connection does not occur, try the following steps:
- ๐ Reboot both devices.
- ๐ฑ On your smartphone, turn on the developer mode and activate debugging by USB (Sometimes helps with Miracast bugs).
- ๐บ On the TV, reset network settings: Settings โ Network โ Resetting network settings.
๐ก
If Miracast isnโt located, try temporarily disabling the VPN or firewall โ they can block Wi-Fi Direct.
Set up Miracast on Xiaomi TVs (Mi TV)
Xiaomi TVs support Miracast through the built-in Wireless screen feature, but its menu location can vary depending on the model and firmware version. Consider the process with the example of Mi TV Q2 and Mi TV A2:
- Activate Miracast Standby: Go to Settings โ Network & Access โ Wireless Screen (or Screen Mirroring). Turn on Miracast slider.
- Set up TV visibility: Select your device settings and set Visibility for All (or Always Allow) to allow your smartphone to detect the TV.
- Connect your smartphone: The TV will show a notification of the connection attempt. Confirm it by clicking Allow.
On older models (such as the Mi TV 4S), you may need to adjust:
- Update your TV firmware to the latest version via Settings โ About TV โ Software Update.
- If Miracast is not on the menu, check for Anyview Cast, an alternative protocol from Xiaomi that is compatible with Miracast.
โ ๏ธ Note: On Xiaomi TVs with firmware older than 2021, Miracast may not work as well due to outdated Wi-Fi Direct drivers. In this case, it is recommended to use an external Miracast adapter (for example, Microsoft Wireless Display Adapter).
Common Problems and Their Solutions
Even with the right setup, users often encounter connection errors, and consider typical scenarios and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| TV undetectable | Wi-Fi Direct is disabled on your TV or smartphone | Restart both devices and check your network settings |
| Connection breaks down after a few seconds | Low signal or interference from other devices | Reduce the distance between devices or change the Wi-Fi channel |
| No sound when broadcasting | Incompatibility of audio codecs | In Miracast settings on your smartphone, select Video Only, then turn on the sound via HDMI or Bluetooth. |
| Lags and stuttering videos | Processor overload or weak signal | Close background applications and reduce broadcast resolution |
If none of the solutions worked, try alternative broadcasting methods:
- ๐ฑ Google Cast: Use the Google Home app to stream via Chromecast (works on Google Home) MIUI 12+).
- ๐ฅ๏ธ DLNA: Suitable for transferring media files (e.g., via Mi Home or via Mi Home) VLC).
- ๐ HDMI-Adapter: For stable connection without delay (e.g, USB-C to HDMI).
What if Miracast doesnโt work at all?
Miracast vs Google Cast: Which is Best for Xiaomi?
Many Xiaomi users confuse Miracast and Google Cast, although these technologies are fundamentally different.
| Criteria | Miracast | Google Cast (Chromecast) |
|---|---|---|
| Type of broadcast | Duplicate the entire screen in real time | Broadcasting content from supported applications |
| Delay. | 50โ100 ms (suitable for gaming) | 200โ500 ms (not suitable for gaming) |
| Demands the Internet. | โ No (works via Wi-Fi Direct) | โ Yes (requires a shared Wi-Fi network) |
| Support for Xiaomi | All models with MIUI 9+ | Smartphones only with Google Mobile Services (not on Xiaomi for China) |
Which protocol should I choose?
- ๐ฎ Miracast is suitable for games, video calls or when you need to show the whole screen without restrictions.
- ๐ฌ Google Cast is convenient for streaming YouTube, Netflix or music, as it does not load the smartphone.
On Xiaomi devices with global firmware (MIUI Global), both protocols are usually available.
- Open the settings โ Connections โ Cast.
- Select the target device.
- If a choice of protocol is available, the system will automatically suggest the best option.

On Xiaomi smartphones without Google Mobile Services (such as the Chinese version), Google Cast will not work, in which case Miracast remains the only option for wireless broadcasting.
How to improve the quality of Miracast broadcasting?
If Miracast works but the image is slowing down or tearing, try the following optimization methods:
- ๐ถ Reduce the distance between devices (optimally up to 3 meters).
- ๐ Disconnect other devices from the same Wi-Fi network to reduce interference.
- ๐ฑ Activate the performance mode on the smartphone: Settings โ Battery โ Performance mode.
- ๐ฅ๏ธ Lower the broadcast resolution in Miracast settings (if available).
For advanced users, there is a way to force the priority of Wi-Fi Direct through ADB:
adb shell settings put global wifi_direct_interface_priority 1This command forces the system to prioritize Wi-Fi Direct over regular Wi-Fi, which can improve Miracast stability.
โ ๏ธ Note: Some Xiaomi models (such as the Redmi Note 10 Pro) may overheat the processor during a long Miracast broadcast.
