Xiaomi’s modern multimedia capabilities make it easy to display images from your smartphone to the big screen, which opens up access to high-quality movies, photos and presentations. Many users often wonder how to duplicate a screen on a Xiaomi TV to use the gadget as a remote control or a game console.
The connection process can vary depending on the device model and version of the Android or MIUI TV operating system. There are both wireless methods using Wi-Fi Direct and Chromecast protocols, and wired solutions for a stable signal without delay. In this article, we will discuss each of the available options in detail.
Before you start setting up, make sure your Xiaomi TV and mobile device are connected to the same wireless network.This is a fundamental requirement for most broadcast technologies to work. Violating this condition will result in gadgets simply not “seeing” each other in the list of available devices.
Use of the built-in Mi Remote function
One of the easiest ways to control and broadcast is to use the Mi Remote app, which is pre-installed on most Xiaomi smartphones and allows you to turn the phone into a universal remote control, and you need to start the application and select the point of adding a new device.
In the menu that opens, select the TV category and then find the manufacturer of your TV, Xiaomi or Mi TV. The app will offer several options for control codes that you need to check consistently on the TV. Once successful pairing is confirmed, you will have full access to the Smart TV interface.
Mi Remote is not limited to channel switching; you can use your smartphone screen to input text, which is especially useful when searching for YouTube videos or installing apps.
- 📱 Automatic search of TVs in the local network
- ⌨️ A convenient virtual keyboard for entering queries
- 🖼️ Quick transfer of photos and videos from the gallery
- 🎮 Game Mouse Mode for Navigating in the Menu
It is worth noting that for the IR remote (if it is in the phone), Wi-Fi is not required, but for the functions of screen duplication network is required. If your phone is not equipped with an IR port, the application will work exclusively through the Wi-Fi router.
⚠️ Note: When using an IR remote, point the top of your smartphone directly to the TV receiver. To work through Wi-Fi, the direction does not matter, only the coverage area of the network is important.
Wireless Display Technology (Miracast)
Miracast is the standard for high-quality wireless video transmission. In Xiaomi TVs, this feature is often built into Android TV or PatchWall. To run the process on the TV remote, find a button with a smartphone image or select the source of the signal “Wireless Display”.
On the smartphone side, you open the control panel and find the Translation or Cast button, which in some versions of MIUI may be called the Wireless Monitor, and then you click it and you start looking for available devices within range.
When the name of your TV appears on the list, click on it to pair, the TV screen may have a request for confirmation of connection, which must be accepted by the remote, and then the image from the smartphone is fully copied to the large screen.
The quality of the image is directly dependent on the power of the Wi-Fi router and the distance between devices. The Miracast protocol creates a direct connection, which minimizes delays, but can consume a significant battery charge of the smartphone.
⚠️ Warning: If an incoming call arrives during the broadcast, the image on the TV may interrupt or the sound will go through the phone speaker.
💡
To reduce delays when playing through Miracast, close the background apps that consume traffic and get closer to the router.
Streaming through Google Chromecast built-in
Most modern Xiaomi TVs run on Android TV, which includes built-in support for Chromecast technology, which allows you to stream content from compatible apps such as YouTube, Netflix, Twitch and many others directly, without duplication of the entire screen.
To use this method, open an app on a smartphone, such as YouTube. Find the broadcast icon (a rectangle with Wi-Fi waves in the corner) and click on it. In the list, select your Xiaomi TV.
Unlike Miracast, the phone is just a remote control, and the video is buffered by the TV itself over the Internet, which saves battery power and provides more stable picture quality, so you can fold the app or use the phone for other tasks while the video is playing on TV.
If you want to stream the Google Chrome browser tab, click on the three-dot menu and select Translate. Then select Translate Screen to duplicate the entire Android interface. This method is especially useful for showing presentations or web pages that don't have a built-in Cast button.
| Characteristics | Miracast | Chromecast | HDMI Cable |
|---|---|---|---|
| Type of connection | Wireless. | Wireless. | Wired |
| Signal delay | Medium | Low (for streaming) | Absent. |
| Battery consumption | High-pitched | Low. | Charging the phone |
| Dependence on Wi-Fi | Tall. | Tall. | No. |
💡
Chromecast is ideal for watching videos from online services, as it reduces the load on the smartphone and provides better stream quality.
Connection via HDMI cable
For users who want maximum image quality without compression and delay, the best solution is a wired connection. You will need a special USB-C to HDMI adapter or an MHL adapter, depending on the model of your smartphone.
Connect one end of the cable to your smartphone and the other to the free HDMI port on the back or side of your Xiaomi TV. Once connected, take the TV remote and press the signal source selection button (usually indicated by the square with the arrow).
In the menu that appears, select the appropriate port number, such as HDMI 1 or HDMI 2. The image should appear instantly. Unlike wireless methods, it does not require network setup or device pairing.
Some older smartphone models may not support video output via USB-If you do, you won't see the image, even if the cable is good.
⚠️ Note: When using cheap adapters, the image may be unstable or absent at all. It is recommended to use original accessories or certified cables from well-known brands.
☑️ Checking before connection HDMI
Configuring third-party applications for duplication
If standard methods don't work or there's not enough functionality, you can use third-party software. Applications like AirScreen, ApowerMirror or TeamViewer greatly expand the control and broadcasting capabilities.
Install the selected app on your Xiaomi TV through the Google Play Store or Mi Store. Then install the companion app on your smartphone. Both devices must be on the same Wi-Fi network.
Run the program on the TV and follow the instructions on the screen to receive the access code or QR-Enter the data in the app on your smartphone to establish a connection, and these programs often allow you to control your phone from the TV remote or vice versa.
Using third-party software may require special permissions, such as "Overlaying on other windows" or accessing a microphone, to correctly transmit sound and image, and be careful when installing applications from unknown sources.

Solving Connection Problems
Even if you set it up properly, you can have technical failures. One of the common problems is that the TV can't see the phone. In this case, try rebooting the router because the network cache might be overflowing. Also check if the router has AP client isolation, which prevents the devices from seeing each other.
If the image is broadcasting but the sound is coming through the phone, check the volume and output settings in the application from which the broadcast is coming. In some cases, you need to manually switch the output device in the Bluetooth or Wi-Fi Display settings.
Lags and twitches often indicate an overloaded Wi-Fi channel. Try to switch the router to a less busy frequency or channel. To stream video in 4K requires a stable speed of at least 25 Mbps.
In rare cases, resetting network settings on a smartphone helps. Go to Settings → Connections → Reset network settings. This will remove stored Wi-Fi passwords, but can eliminate software conflicts that prevent screen duplication.
