Today’s Xiaomi Mi TVs have evolved into powerful multimedia centers that can stream content directly from your smartphone or tablet. The wireless screen projection feature allows you to display photos, videos, games and even the desktop of a mobile device without unnecessary wires, especially when you need to show a presentation to colleagues or arrange a home theater for the whole family.
However, the activation process can seem confusing for beginners, as the Android TV shell or PatchWall proprietary settings are scattered across different menus. There are different data protocols such as Miracast, Google Cast and DLNA, each of which has its own connectivity features. In this article, we will discuss in detail all the ways to enable a projection on a Xiaomi TV, and solve typical synchronization problems.
Before you start setting up, make sure your device is compatible with wireless image output technology. Most modern Android and iOS smartphones support the required standards, but operating system versions may differ. Proper hardware preparation is 90% of the success in setting up a multimedia system.
Preparation of equipment and Wi-Fi network
The foundation of stable wireless projection is a good network connection. For Miracast or Google Cast to work properly, it is critical that both devices — TV and smartphone — are on the same LAN, which means that they must be connected to the same router.
Pay attention to signal frequency. If your router supports dual-band operation, it's better to use a 5GHz network. It provides the higher bandwidth that is needed to transmit high-resolution video without delays and artifacts.
⚠️ Note: If one device is connected to a guest Wi-Fi network and the other is connected to the main one, or if the router uses "Guest Network" mode, devices may not see each other due to customer isolation.
Check the signal strength on both devices. A weak signal can cause permanent connection breaks or "squares" in the image while playing video. Ideally, the distance between the router and the TV should not exceed reasonable limits, especially if there are load-bearing walls between them.
☑️ Checking before connection
It’s also worth mentioning that for some features, such as initial device search through Google Home, the smartphone must have Bluetooth enabled. Although video streaming is over Wi-Fi, Bluetooth helps devices detect each other faster in space.
Activation of the built-in wireless screen function
Xiaomi Mi TVs already have the necessary software module for receiving the signal pre-installed. You do not need to buy additional consoles or adapters if the model supports Smart TV. To start the standby mode, you need to find the corresponding application in the main menu.
If you use the remote, go to the application section, and you need to find a shortcut called Wireless Screen or Wireless Display. In some versions of PatchWall, this feature may be called Translation or be placed in a separate Tools folder.
When you start the app, you'll see a waiting window on your TV with the device name, like MI TV-XXXX. This is the name you'll be looking for on your smartphone's list of available networks. The interface may vary depending on the model's year of release and the regional version of the software.
What to do if there is no application?
Do not close this window during the pairing process. While the waiting logo is on the TV screen, the Wi-Fi Direct module is active and ready for handshake treatment with the mobile phone. If the screen is turned off or switched to the screensaver, the reception mode can be deactivated.
Broadcast from Android-smartphone
Owners of Android devices have several projection implementation options, as shell manufacturers often change feature names.The standard protocol supported by Xiaomi Mi TV is based on Miracast technology. To launch, open the notification curtain on your smartphone.
Find an icon that can be called Translation, Smart View, Projection, or Wireless Monitor, and the location of this item depends on your phone’s brand (Samsung, Xiaomi, Huawei, etc.) and then you tap it, it starts looking for available displays within range.
When your TV (e.g. Living Room Mi TV) appears on the list, click on it. The TV screen may have a request to confirm your connection. Use the remote to press OK or Accept.
- 📱 On smartphones. Xiaomi/Redmi/Poco: Go to Settings. → Connection and sharing → Broadcast and switch on the switch.
- 📺 On Samsung: the feature is called Smart View and is located in the Quick Settings Panel.
- 🌐 On pure Android: use the “Translate screen” button in quick settings.
Once you've successfully connected, the image from the phone is completely copied to the TV, so you can flip the smartphone horizontally, and the picture will occupy the entire screen. To exit projection mode, just turn off the function in the phone's menu or press the Home button on the TV remote.
💡
Use the horizontal orientation of your smartphone to watch full screen video to avoid black bars on the sides of the image on your TV.
Using Google Chromecast technology
In addition to direct screen projection (mirror), Xiaomi Mi TVs support the built-in Google Cast protocol.This is a more advanced way that allows you to stream content from specific applications (YouTube, Netflix, VK Video) without loading on the phone’s battery.
Unlike Miracast, it doesn't transmit a full screen image, it transmits a link to a video stream. The TV downloads video from the Internet on its own, while the phone is only a remote control, and this method requires that the Chromecast built-in service be installed and active on the TV.
Open an app, like YouTube, on your smartphone. In the corner of the video player, click on the wave rectangle icon (Cast logo). Select your TV from the list. The video will play on the big screen, and you can roll the app up and do other things.
| Parameter | Miracast (screen translation) | Google Cast (Chromecast) |
|---|---|---|
| Principle of work | Real-time mirroring of images | Transfer of reference to flow |
| Phone load | High (fast battery discharge) | Low (management only) |
| Quality. | Depends on the Wi-Fi signal, possible lags | Stable, maximum quality |
| Possibility of multitasking | No (phone screen is busy) | Yes (can use the phone) |
It's important to understand the difference between these methods. If you want to show a photo from a gallery that's not on the Internet, or if you want to demonstrate how the app works, use Miracast. If you want to watch a movie from an online movie theater, Google Cast is the preferred method.
💡
Google Cast saves battery power and provides more stable picture quality, as the TV takes the load of decoding video on itself.
Broadcast from Apple devices (iOS/macOS)
Apple users are faced with the fact that native AirPlay technology is not supported by Xiaomi TVs out of the box in some regions or old firmware. However, modern Android TV models often have built-in support for AirPlay 2.
Check if you have the appropriate option in your TV settings. Go to Settings → Apple AirPlay and HomeKit. If you have one, just turn it on. Then your TV will appear on your iPhone at Screen Replay (two rectangles).
If there's no built-in support, don't despair. You can install a third-party app from the Google Play Store directly onto your TV. Popular options include AirScreen or Receiver for AirPlay. These programs emulate an AirPlay receiver, making the TV visible to Apple devices.
⚠️ Note: With third-party AirPlay emulator apps, there may be a slight delay in sound (dissynchronization). This is not critical for movies, but it can be noticeable for games.
The connection process is standard: you run the receiver app on TV, open the Control Point on your iPhone, select Screen Replay and click on the name of the TV, and the code that appears on the screen must be entered on the phone for the first pairing.
Image projection from a laptop or PC
Output from your computer to your Xiaomi Mi TV is also possible wirelessly if your laptop is running Windows 10 or 11. These operating systems have built-in support for Miracast technology.
Press the Win + K keyboard. On the right, the Connect panel will come out. The system will start looking for available wireless displays. Make sure the Wireless Screen app we talked about earlier is running on the TV.
Once you select a TV, Windows will establish a connection in the list, and you can choose to work on the mode: duplicate the screen (copy), expand the desktop (second monitor), or output only to the second screen, which turns the TV into a full-fledged monitor.
For macOS owners, the situation is similar to iPhones — either AirPlay 2 on TV or emulator app support will be required. Direct HDMI cable connection remains the most reliable, but wireless is more convenient for presentations.
If the connection is interrupted or the image twitches, try lowering the output resolution on the laptop or bringing the computer closer to the router. Channel bandwidth is critical for transmitting images at 1920×1080 resolution and higher.
Solving Connection Problems and Errors
Despite the simplicity of the technology, users often face difficulties, and the most common problem is that devices can't see each other, 90% of the time, this is solved by checking that they're on the same network. AP (AP Isolation, which prevents devices within the network from sharing data.
Another common mistake is low performance or lag, which can be caused by overloading the Wi-Fi channel by neighbouring routers, and try changing the router's broadcast channel settings or switching to 5GHz if you haven't already done so.
- 🔄 Reboot the router and TV – this resets the cache of network modules.
- 📡 Closer to the router if the signal is weak.
- 🛡️ Turn it off. VPN On a smartphone, it can block a local connection.
- 📺 Update the TV firmware through the Settings menu → About the system → Update.
If nothing works, try resetting your network settings on your TV. Sometimes, the accumulated errors in the Android TV network drivers interfere with the proper operation of the projection function. Also check if the router is not limited by the number of connected devices.
