Broadcasting your smartphone screen to Xiaomiโs big TV opens up new possibilities, from watching movies to showing presentations or games on a wide display. However, not everyone knows how to set up this connection correctly, especially if it comes to different communication protocols or outdated TV models. In this article, we will analyze all the current ways of transmitting images โ from wireless technologies to wired connections โ and also explain how to avoid typical configuration errors.
Xiaomi TVs (Mi TV, Redmi Smart TV, Xiaomi TV A, etc.) have several broadcast standards at the same time, which means that you can choose the best method depending on the available equipment: for example, Miracast or Google Cast will suit Android smartphones, and for iPhone โ AirPlay (on supported models), while even older TVs without built-in Wi-Fi can be connected through adapters or cables.
It is important to consider that the quality of the broadcast depends not only on the chosen method, but also on the technical characteristics of the devices. For example, to transmit video in 4K resolution you will need Wi-Fi 5 (802.11ac) or wired connection over HDMI, whereas for simple duplication of the smartphone screen, Wi-Fi Direct will suffice. Next, we will discuss each method, its pros, cons and nuances of settings.
1. Wireless streaming on Miracast (for Android)
Miracast is a wireless video and audio standard that supports almost all modern Android smartphones (since version 4.2) and Xiaomi TVs, with the main advantage of the method being that there is no need for a router: devices connect directly via the Wi-Fi Direct protocol.
To begin the broadcast:
- ๐ฑ On your smartphone: open Settings โ Connections โ Screen broadcast (or Wireless display depending on firmware). From the list of available devices, select your Xiaomi TV.
- ๐บ On TV: Go to Settings โ Connection and sharing โ Wireless display (Miracast) and activate the option.
- ๐ Wait for the devices to pair. You may see a request on the phone screen for confirmation of connection โ click Connect.
The speed and stability of Miracast broadcasts depend on the distance between devices (up to 5 meters optimally) and the presence of interference from other wireless networks. If the image is slowing down, try:
- ๐ถ Switch Wi-Fi on your phone to 5GHz (if supported).
- ๐ Close background applications on a smartphone that consume resources.
- ๐ Restart both devices and reconnect.
โ ๏ธ Note: Some Xiaomi models (e.g. Mi) TV 4A 2018) Miracast can be hidden in the developer menu. To activate it, go to Settings โ About TV and 5 times click on the item Version MIUI TV. After that, in the settings will appear section For developers, where you need to turn on the wireless display.
2. Broadcast via Google Cast (Chromecast)
If your Xiaomi TV runs on Android TV (e.g. Mi TV Q1, Xiaomi TV A Pro), it supports Google Cast technology, also known as Chromecast. Unlike Miracast, here the stream is not from the smartphone screen, but through the cloud: you โsendโ content (video, music, photos) to the TV, and the phone is used as a remote control.
Instructions for setting:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- On your TV, open the Google Play Movies app, YouTube or any other app that supports Cast (icon) ๐ก top-right).
- On your smartphone, run the same app, tap the Cast icon and select your Xiaomi TV.
- Choose the content to watch โ it will start to be broadcast on TV.
The advantages of Google Cast:
- ๐ฌ Ability to stream content in high resolution (up to) 4K HDR supported-model).
- ๐ฑ The phone is not locked โ you can use other apps while streaming.
- ๐ Automatic sync with Google account (e.g. YouTube browsing history).
Limitations:
- ๐ซ Not all apps support Cast (for example, some streaming services may block streaming).
- ๐ถ Requires a stable connection to the Internet โ with a weak signal, the video will โslow downยป.

3. HDMI wired connection (for maximum quality)
If you need to transmit images without delay and at maximum resolution (for example, for games or professional work), the best option is a wired connection via HDMI.
- ๐ฑ Smartphone with support USB-C Micro-USB (depending on the model).
- ๐ adapter USB-C/HDMI or Micro-USB/HDMI (for example, Xiaomi USB-C to HDMI Adapter).
- ๐บ Cable HDMI (usually comes with a TV set).
Step-by-step:
- Connect the adapter to your smartphone and the HDMI cable to your adapter and TV (in the HDMI IN port).
- On the TV, select the appropriate signal source (e.g. HDMI 1 or HDMI 2).
- On the smartphone may appear a request for permission to transfer the image โ confirm it.
Advantages of wired connection:
- ๐ฎ Minimum latency (important for games or video editing).
- ๐ Support for permits up to 4K@60Hz (when using high-quality cable).
- ๐ No dependence on Wi-Fi or mobile internet.
โ ๏ธ Note: Some Xiaomi smartphones (e.g. Redmi Note 10 Pro) when connected to the phone HDMI Charging can be turned off via the same port. To avoid the phone draining during the broadcast, use a Power Delivery-enabled hub (e.g. Xiaomi) USB-C Hub).
| Connection method | Max, permission. | Delay. | Internet is required | Supported devices |
|---|---|---|---|---|
| Miracast | 1080p@30Hz | 100-300 ms. | No. | Android, Windows |
| Google Cast | 4K@60Hz | 50-200 ms. | Yes. | Android, iOS |

4. Stream from iPhone to Xiaomi TV (AirPlay)
Owners of iPhones or iPads can stream the screen to Xiaomi AirPlay-enabled TVs, which is available on Mi TV Q1E, Xiaomi TV A Pro 2022 and later. If your TV doesnโt support AirPlay out of the box, you can use external devices like Apple TV or Roku adapter.
How to connect:
- Make sure your iPhone and TV are connected to the same Wi-Fi network.
- On your TV, activate AirPlay in the Settings menu โ Connection and Sharing โ AirPlay.
- On your iPhone, swipe down from the top right corner of the screen to open Control Point.
- Slip on the screen duplication block and select your Xiaomi TV.
Features of AirPlay on Xiaomi TV:
- ๐ต Supports broadcasting not only the screen, but also individual media files (music, photos).
- ๐ To protect content, you can turn on a password in the AirPlay settings on your TV.

- Run ApowerMirror on both devices and select Broadcast on TV.
- On your smartphone, tap the name of your TV in the list of available devices.
- Confirm TV connection (may require input) PIN-code).
Advantages of third-party applications:
- ๐ง More settings (for example, adjusting the quality of the stream or sound).
- ๐ฑ Support for outdated TV and smartphone models.
- ๐ฎ Additional functions (screen recording, real-time annotations).
โ ๏ธ Note: When using third-party screencast apps, never enter bank card details or account passwords during an active session. Some apps may stream screen images through their servers, putting sensitive information at risk of leakage.
