Xiaomi Mi TV and Redmi TV are no longer just on-air devices, becoming full-fledged multimedia centers. One of the most sought-after features for ecosystem owners is the ability to instantly stream content from a smartphone to a large screen without using extra wires, allowing you to watch high-resolution movies, show family photo galleries or even play mobile games on a wide diagonal.
The screen can be streamed in a number of ways, each with its own specifications and use cases: Mi Cast’s embedded protocols, Miracast standard, and Google Cast technology provide basic functionality available out of the box, but additional customization or third-party software may be required for iOS users or app owners.
In this guide, we will take a look at all the available ways to sync devices, fix common connection errors, and answer questions that arise when setting up a network, learn how to ensure a stable 4K video stream and why sometimes a phone doesn’t see a TV, even if they are in the same room.
Network requirements and preparatory settings
The foundation of successful wireless broadcasting is the right organization of the local network. In order for your smartphone and Xiaomi TV to communicate with minimal latency, both devices must be connected to the same Wi-Fi network, which means that they must work through the same router and, ideally, be on the same subnet.
If your router supports dual-band mode, it is recommended to use 5 GHz. This range provides higher bandwidth, which is critical for transmitting high-resolution video stream without artifacts and buffering. 2.4 GHz frequency can be used, but it is more prone to interference from household appliances and neighbourhood networks.
⚠️ Warning: Make sure the router has disabled the Client Isolation function. AP If this option is active, devices on the Wi-Fi network will be prohibited from communicating with each other, and the phone will no longer be able to search for a TV.
It’s also worth checking that both devices have a wireless module enabled. In some cases, especially on other brands’ Android smartphones, you need to activate the Wi-Fi Direct or Translation function in the notification curtain before you start looking for displays. On Xiaomi TVs with a PatchWall shell or Android TV, the corresponding module is usually active by default, but its status can be rechecked in the network settings.
☑️ Checking connection readiness
Use of the built-in Mi Cast and Miracast function
The most native way for Xiaomi and Redmi smartphone owners is to use Mi Cast technology.This feature is deeply integrated into the MIUI and HyperOS shell, providing stable connection and minimal input latency. To start, you need to open the control panel (swipe down or up depending on navigation settings) and find the Translation or Mi Cast icon.
Once activated, the phone will start scanning available devices on the network. Once your Xiaomi TV appears on the list, just tap its name. On the TV screen, you may have a request for confirmation of connection, which you need to agree with the remote, This method implements the Miracast protocol, which broadcasts exactly the image from the smartphone screen, rather than just sending a link to the video.
For users of other Android devices, the algorithm is similar, but the path to the feature may differ, often called Translation, Smart View (Samsung), Screen projection (Huawei) or Translate. In the settings of the Xiaomi TV itself, you can also find the Wireless Display or Miracast app, which makes the TV visible to external devices.
What is the difference between Mi Cast and Miracast?
It is important to understand that when using this method, the smartphone screen is completely duplicated on TV, which means that any notifications, incoming calls or messages will be visible to everyone in the room, and the orientation of the image (portrait or landscape) will change dynamically depending on the position of your phone.
Broadcasting via Google Home and Chromecast
Most modern Xiaomi TVs run Android TV, which includes built-in support for Google Cast (formerly known as Chromecast built-in), a method that is considered the most convenient way to view content from apps, since it does not transmit a picture of the screen, but a link to the video stream that the TV plays itself.
To do this, you need to have a Google Home app installed on your smartphone. Once you have the app launched and logged in to your Google account, it will automatically detect the TV on the network. When you click on the device icon, you will see a "Cast my screen" button, which will allow you to clone the image, similar to Miracast, but using Google's infrastructure.
But the main power of Chromecast is within streaming apps. When you open YouTube, Netflix, IVI or Kinopoisk, you'll find a familiar broadcast icon in the corner of the video player, and when you click on it, the video will run directly on the TV, and the phone will act as a remote control, saving the battery of the smartphone and allowing it to be used for other tasks while watching.
| Characteristics | Mi Cast / Miracast | Google Cast (Chromecast) |
|---|---|---|
| Type of transmission | Screen duplication (pixel to pixel) | Streaming Link Transfer (DLNA/HTTP) |
| Impact on the battery | High (screen and processor active) | Low (TV plays itself) |
| Image quality | Depends on the power of the phone and Wi-Fi | Maximum (Native TV Decoding) |
| Notifications on TV | Broadcast. | Not broadcast. |
Connecting Apple devices (iOS) to Xiaomi TV
Owners of iPhone and iPad are less fortunate, as Apple’s ecosystem uses its own AirPlay protocol, which is not natively supported by most Xiaomi TVs with pure Android TV. However, the problem can be solved quite simply. Many new Xiaomi TV models already have built-in support for AirPlay 2, which is checked in the system settings or through the Apple TV app on the TV itself.
If there is no built-in support, the only solution is to install a third-party emulator app on the TV itself. In the Google Play Store on the TV, you need to find and install an application, such as AirScreen, AirPin or DoCast. Once you run this application, the TV emulates the AirPlay receiver, becoming visible to Apple devices.
The connection process is standard: open the Control Point on the iPhone (swipe down from the top right corner or bottom up on older models), select Screen Replay and find the name of our TV. It is important to note that when using emulators, the latency can be slightly higher than when using a native connection, and the picture quality is sometimes limited to 1080p resolution.
⚠️ Note: Free versions of AirPlay emulator apps may occasionally display ads or session timers on your TV (e.g. AirScreen). Continuous use without restrictions often requires a paid subscription within the TV app.
Third-party applications and alternative methods
When standard methods fail or require advanced functionality, universal translation applications come to the rescue, with Web Video Caster being the leader in this niche, unique in that it allows you to stream video not only from popular streaming sites, but also from websites containing video players, as well as from the local network (SMB/DLNA).
The way these apps work is the same: you install a receiver app on a Xiaomi TV (often called Web Video Caster Receiver) and a source app on a smartphone. QR-If you have a code or a search on the web, the phone tells the TV to play the file directly, and it's the perfect way to watch videos from unfriendly sources or file storage.
Another powerful tool is the Xiaomi Mi Remote app or universal remotes, which sometimes have a media file transfer feature, although it is less convenient than in specialized cast applications. Also worth mentioning is the ability to wired connect via the USB-C to HDMI adapter if your smartphone supports video output (DisplayPort Alt Mode), which guarantees a perfect picture without delay.
💡
For heavy-duty broadcasting 4K-Files from your computer to your Xiaomi TV use the protocol SMB via built-in media player TV. This will provide the maximum speed and quality without compression that often occurs in wireless transmission.
Solving problems and fixing connection errors
Despite the simplicity of the technology, users often face a situation where the phone does not see the TV. The most common reason is the use of different Wi-Fi frequencies. Make sure that the phone does not sit on the router's guest network and the TV is connected to the main one, or vice versa. Routers with Smart Connect sometimes incorrectly handle device detection packets between the 2.4 and 5 GHz bands.
A second common problem is outdated software. Check for updates for the Android TV app, Google Play Services, and the TV's own system firmware in Settings → About TV → System Information. The absence of fresh security patches can block detection protocols.
If nothing works, try resetting the network settings on both devices. On the TV, you can do this through Settings. → Network and Internet → Network resetting. Also effective is a complete router reboot, because it overflows the table. ARP or DHCP-Errors can prevent devices from being visible on the local network.
💡
90% of connection problems are solved by restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
