Xiaomi’s modern Android TVs offer users many ways to interact with multimedia. One of the most popular and convenient ways to transfer images from a smartphone or tablet to a large screen is Miracast, a feature that allows users to broadcast the contents of a mobile device’s display without wires, providing high quality images and sound in real time.
The activation process may seem complicated at first glance, but Xiaomi TV is as simple as possible for the end user. In most cases, you do not need to install third-party applications or perform complex manipulation of access codes, just make sure that both devices are on the same network, and follow a few simple steps in the settings menu.
In this article, we will take a closer look at the nuances of the wireless protocol on Xiaomi TVs, where to look for hidden settings, how to fix common connection errors, and what alternatives exist if the standard method does not work for some reason.
What is Miracast and how does it work on Xiaomi TV?
Miracast is a standard for wirelessly transferring multimedia content between devices. Unlike Chromecast, which requires support from specific applications, Miracast broadcasts exactly what you see on your smartphone or laptop screen. On Xiaomi TVs, this feature is often integrated into the system layer and can be called differently, such as “Wireless Display” or “Screen Mirroring”.
The principle of operation is based on creating a direct Wi-Fi connection between the receiver (television) and the signal source (smartphone). It is important to understand that for stable operation it is not necessary to have Internet access, although both devices must support the Wi-Fi Direct standard. The Miracast protocol on Xiaomi TV compresses the video stream in real time, so the quality of the picture depends on the power of the Wi-Fi router signal and the distance between devices.
Using this feature turns your TV into a huge monitor for any task. You can show photos from the gallery, run mobile games on a large screen or show presentations from a laptop. The Android TV system installed on the Xiaomi Mi TV has built-in support for this standard, eliminating the need to buy additional adapters or dongle devices.
What is the difference between Miracast and Chromecast?
Preparing devices for wireless connection
Before you start setting up, you need to do a set of preparatory steps to avoid 90% of potential connectivity issues and ensure stable data transfer, and ignoring these simple steps often leads to devices simply not seeing each other on the list of available networks.
First of all, make sure that your Xiaomi TV and mobile device (smartphone or tablet) are connected to the same Wi-Fi network.If your router has a 2.4 GHz and 5 GHz band division, it is advisable to use the 5 GHz band for high-resolution video transmission, as it provides higher bandwidth.
☑️ Checking before connection
It’s also worth checking the software’s relevance on your TV. Manufacturers regularly release updates that improve the stability of wireless modules. Go to the settings menu and find the system section to check for new versions of Android TV.
💡
For maximum data transfer speed, try to place your smartphone no further than 3-4 meters from the TV and in line of sight, without obstacles in the form of walls or furniture.
Step-by-step instructions for activating the function on the TV
The process of enabling the broadcast function on Xiaomi TVs may vary slightly depending on the version of the operating system and regional firmware (Global or CN). However, the general algorithm of actions remains unchanged and requires sequential passage of several menu items.
Take the remote control and press the configuration button (cog icon). In the menu that opens, you need to find the partition responsible for connections or network. In some versions of the PatchWall interface or pure Android TV, this option can be displayed in the main settings menu.
The algorithm of actions is as follows:
- 📺 Go to the Settings section on the main TV screen.
- 🔗 Select the Application or the Network and the Internet, depending on the model.
- 📡 Find the Wireless Display, Screen Mirroring or Broadcast option.
- ✅ Press the activation button to turn the TV into standby mode connection.
Once this option is enabled, the TV will show a message that the device is ready to connect, and perhaps the name of the TV will be displayed, which will be visible to other devices.
💡
On some Xiaomi TV models, Miracast is enabled by default and does not require manual activation in the menu, just run a search on a smartphone.
Configure broadcasting with Android and Windows devices
Once the TV is ready, you need to initiate a connection from a mobile device or computer. On smartphones running Android, the procedure is as standardized as possible, but the menu names may differ from manufacturer to manufacturer (Samsung, Xiaomi, Huawei, etc.).
Lower the notification curtain on your smartphone and look for the Broadcast, Smart View, Wireless Projector or Mi Cast icon. If the icon is not available in quick access, go to the screen settings and look for the Connection and Sharing section. Select your Xiaomi TV name from the list.
For users of the operating system Windows 10 and Windows 11 process also does not require the installation of additional software:
- 💻 Press the key combination Win + K on the keyboard.
- 📺 In the right side of the screen will appear the panel "Connection".
- 📡 Choose your Xiaomi TV TV list of available devices.
- 🔒 If a connection request appears on the TV screen, confirm it with the “OK” button on the remote control.
If the connection is successful, the screen of the smartphone or computer monitor is duplicated on the TV, the image latency is minimal and depends on the load of the wireless channel.
Solving common problems and errors
Despite the simplicity of the technology, users often face situations where devices can’t find each other or the connection is constantly broken, and one of the most common reasons is the use of a guest Wi-Fi network or the isolation of customers on the router, which prevents devices from seeing each other on the local network.
If you experience audio delays or video desynchronization, try to reduce the quality of the transmitted image in the broadcast settings (if such an option is available on a smartphone).
The table below will help quickly diagnose the problem by symptoms:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| TV not visible on the list | Different Wi-Fi networks | Check to connect both devices to the same router |
| Black screen when connected | Protecting DRM Content | Some apps (Netflix) are blocking Miracast. |
| Persistent communication breaks | Weak Wi-Fi signal | Get closer to the router or TV |
| No TV sound. | Phone speaker selected | Switch audio output in Bluetooth/Audio settings |
It is important to note that some content-protected apps, such as Netflix or Disney+, may block the transmission of an image through Miracast due to copyright protection policies.In such cases, the image will be black, although sound can be transmitted.
⚠️ Note: If you have a “failed to connect” error when connecting a Windows laptop, try updating your wireless adapter drivers on your computer or temporarily disabling antivirus software that may block the connection.
Alternative ways to display the image
If the standard Miracast protocol doesn’t work, or your smartphone model doesn’t, the Xiaomi ecosystem offers other efficient solutions. Google Chromecast’s built-in support is a great alternative for streaming videos from apps.
For owners of Xiaomi and Redmi smartphones with a shell MIUI or HyperOS, there is a proprietary feature Mi Cast. It provides deeper integration and often works more stable than the standard Android protocol, and you can find it in the “More” menu in the notification curtain.
Also worth considering is the possibility of using a wired connection via a USB-C to HDMI adapter, which ensures no delays and maximum image quality, which is critical for gaming or text work, but requires the appropriate cable and does not support all smartphones.
⚠️ Note: When using a wired adapter, make sure it supports mode MHL DisplayPort Alt Mode, otherwise the TV will only display the desktop without sound.
