Modern TVs of the brand Xiaomi are powerful multimedia centers capable of streaming content not only from built-in applications but also from external devices. One of the key features for wireless data transmission is the technology Wi-Fi Direct, which allows you to connect gadgets directly, without using an intermediate router. This is especially useful when your home network is overloaded or your router is located far from the reception area.
Many users confuse this protocol with a regular local area network connection or standard Miracast, but the difference is significant. In direct connection mode, the TV effectively becomes an access point to which you connect your smartphone or tablet for instant photo and video transfer or screen mirroring. Understanding this mechanism helps avoid common setup mistakes.
In this guide, we will examine in detail the process of activating the function on various versions of the operating system. Android TV And PatchWall, used in televisions Mi TVYou'll learn about security nuances, interface differences, and troubleshooting methods when a device doesn't recognize a signal source. Get ready for complete synchronization of your media space.
What is Wi-Fi Direct and why is it needed on Xiaomi TV?
Wi-Fi Direct — is a wireless communication standard developed by the Wi-Fi Alliance that allows devices to connect directly to each other. Unlike a classic connection via a router, here one device (in our case, a TV) Xiaomi) acts as an access point. This means you don't need a stable internet connection to stream heavy 4K video or play games with minimal latency; all you need is a working Wi-Fi module in both devices.
The main advantage of this technology is its data transfer speed and its independence from the quality of your home router. If your router is older and doesn't support the standard, 802.11ac or Wi-Fi 5, then a direct connection will allow you to stream content in higher quality without buffering. TVs Mi TV This protocol is often used for functions Miracast and wireless image output.
⚠️ Please note: When activating Direct Connection mode, the TV may temporarily lose internet access, as its Wi-Fi module switches to receive a signal from your phone. To watch online movies at this point, you will need a separate cable connection or reconnect.
Furthermore, this protocol provides a higher level of security when transferring confidential files, as the connection is established using a unique WPA2 encryption key. Unlike an open network in a cafe, access to your TV via Wi-Fi Direct requires PIN code confirmation or physical pressing of a button on the remote control, which prevents unauthorized access by third parties.
Checking compatibility and preparing equipment
Before you begin setting up, you need to make sure your equipment supports the required standards. Almost all modern models Xiaomi Mi TVDevices released after 2017 are equipped with a built-in Wi-Fi module that supports Direct mode. However, on some budget models or older firmware versions, this feature may be hidden by software or may be unstable.
It is also important to check the operating system version. Interface PatchWall, typical for Russian versions of TVs, may have differences in the settings menu compared to the global version Android TVMake sure your smartphone's wireless module is also enabled and its network connection drivers are updated.
| TV model | Wi-Fi Direct support | Interface Features | Maximum resolution |
|---|---|---|---|
| Mi TV Stick 4K | Yes (via Miracast) | Android TV | 4K UHD |
| Mi TV P1 43" | Yes (built-in) | PatchWall / Android | 4K UHD |
| Mi TV 4S 32" | Yes (built-in) | PatchWall | Full HD |
| Mi TV Stick (1080p) | Yes (via Miracast) | Android TV | Full HD |
For proper operation, we recommend updating your TV's software to the latest available version. Manufacturers frequently release patches that fix communication protocol errors. Checking for updates takes only a couple of minutes but can eliminate many future issues.

Using the built-in Wireless Display (Miracast) app
The most common use case for this technology is mirroring a smartphone's screen. This is done in TVs Xiaomi the application is pre-installed Wireless Display (Wireless monitor). It is responsible for receiving the video stream via the protocol Miracast, which is based on Wi-Fi Direct.
Launch the application Wireless Display on the TV. The screen will display the message "Ready to connect" or the name of your device, which will be visible in the list of available networks on your phone. The name is usually formatted as Android_XXXX or MiTV_XXXX.

What to do if the phone doesn’t see the TV?
Make sure Bluetooth is enabled on both devices (it's often used for the initial handshake). Restart the router, even if you're using Direct mode, as system services may conflict. Try temporarily disabling your antivirus software on your smartphone.
Connecting Android smartphones and tablets
The process of connecting devices based on Android This usually goes smoothly thanks to the protocol's deep integration into the system. However, there are some nuances depending on the OS version and the manufacturer's shell. If automatic detection doesn't work, you can try forcing a connection through the Wi-Fi settings.

- 🔒 Safety: Always check that the PIN code on your phone and TV screen matches before confirming.
- 📶 Stability: Don't move too far from the TV during the session, as the range of Wi-Fi Direct is shorter than that of a router.
- 🔋 Power consumption: Direct connection mode drains your smartphone's battery faster.
If the connection is successful, your smartphone's screen will be mirrored to the TV. You can play videos, photo albums, or even games. Input lag is minimal in this mode, but for fast-paced shooters, a wired connection or gaming modes are still recommended.
Stream from iPhone and iPad (AirPlay)
Equipment owners Apple People often wonder how to enable Wi-Fi Direct, but for them the process looks different. TVs Xiaomi with support Android TV 9.0+ and newer have built-in support AirPlay 2This means you don't need any additional apps for basic streaming as long as both devices are on the same network.
However, if you want to use a direct connection (without a router), standard AirPlay may not work in the classic sense, as it's designed for a local network. In this case, you'll need to install an intermediary app on your TV, such as AirScreen or ApowerMirror from Google Play Store.
After installing and launching the application on your TV:
- Open the app on your TV and it will create a virtual hotspot.
- On iPhone, open Control center (swipe down from the top right corner or up from the bottom).

- From the list, select the name of your TV or running application.
Image from the device iOS will appear on the screen. Picture quality will depend on the TV's processor power and the version of the intermediary app. This method is great for viewing photos and videos in 4K, but for gaming, there may be a noticeable delay.
Solving common connection problems and errors
Despite the simplicity of the technology, users often encounter difficulties. The most common issue is that the TV doesn't appear in the list of available devices. In 90% of cases, this can be resolved by simply rebooting both devices. Unplug the TV for 10 seconds to clear the network service cache.
Another common error is "Unable to connect" or constant disconnects. This can be caused by airwave congestion if you live in an apartment building with dozens of neighboring routers. In this case, changing the Wi-Fi channel in the router settings (if it's being used as a bridge) or moving the devices closer together can help.
It's also worth paying attention to antivirus software and firewalls. Sometimes they block incoming connection requests via the protocol. Wi-Fi DirectTry temporarily disabling protection for diagnostic purposes.
