Xiaomi’s modern smart TVs feature advanced multimedia features that allow you to display images from your smartphone or tablet to the big screen without using wires.This opens up opportunities to view photos, gallery videos, online movies and even mobile games to the full wall. Users often wonder how to set up this process, as standard methods may vary depending on the version of the operating system and device model.
In this article, we will take a closer look at all the available screen broadcasting options, from Mi Cast’s built-in system features to third-party apps for iOS and Android. You’ll learn how to ensure a stable connection, which router settings can affect image quality, and how to avoid sound delays. The right configuration will allow you to enjoy content in high resolution without compression artifacts.
Before you start setting up, you need to make sure that your hardware is ready to go. Most modern Xiaomi models, including the Mi TV series, Redmi TV and Android TV, support wireless data protocols. However, there are nuances regarding the versions of the MIUI TV or Android TV firmware that can change the location of menu items. We will look at universal solutions that are relevant to most current models.
Preparation of equipment and network
The foundation for successful broadcasting is a stable LAN. The Wi-Fi router must work correctly, and both devices — the smartphone and the TV — must be on the same subnet. This means that they must be connected to the same wireless signal. If you have a dual-band router, make sure that the gadgets are not spaced at different frequencies (2.4 GHz and 5 GHz), although modern routers often combine them into a single network.
The quality of the image transmitted depends on the bandwidth of the channel. 1920×1080 or 4K If the distance between the router and the TV is large, there may be interruptions in the flow. LAN-cable, if the model allows, or bring the router closer to the receiving point.
Verification of software is another critical step: outdated firmware on Xiaomi TV may not contain the current codecs or security protocols necessary for handshake-process connection. Go to system settings and check for updates. Also make sure that the smartphone is enabled geolocation, as Android often requires it to search devices on the local network.
Use of the built-in Mi Cast function
The most native way for Xiaomi and Redmi smartphone owners is to use the Mi Cast system utility.This feature is deeply integrated into the MIUI and HyperOS shell, providing minimal latency when transferring an image. To start, you need to deploy the notification curtain and find the "Translation" or "Mi Cast" icon. If there is no icon, you can add it through the Quick Settings editor.
Once activated, the phone will start searching for available displays on the network. The TV screen may have a request for confirmation of connection, which must be received by the remote. Some TV models require you to pre-start the Wireless Monitor or Miracast app in the signal source menu to make the TV visible for search.
☑️ Checking before launching the Mi Cast
It is important to note that when using Mi Cast, the smartphone screen is completely duplicated on the TV, which means that any notifications, incoming calls or messages will be visible to everyone in the room. For privacy, it is recommended to turn on Do Not Disturb mode before starting to view.
⚠️ Note: When using Mi Cast in horizontal (landscape) mode, the image on the TV can scale with black fields on the sides if the aspect ratios of the screens do not match.
Broadcasting via Google Home (Chromecast)
Most Xiaomi TVs run on Android TV, which includes built-in support for Chromecast built-in technology, which allows you to stream content not only from Android smartphones, but also from iOS devices using the Google ecosystem.
The setup process is simple: open Google Home, find your TV in the list of devices, and click on Translate screen. Unlike Mi Cast, it uses a more streamlined protocol that often provides better stability and lower latency, especially when streaming videos from apps like YouTube or Netflix.
| Characteristics | Mi Cast (Miracast) | Google Home (Chromecast) | Third-party annexes |
|---|---|---|---|
| Type of connection | Straight (P2P) | Through the router. | Depends on the app. |
| Delay. | Medium | Low. | Tall. |
| Screen locking | Impossible. | Possible (in supported apps) | Partially. |
| Quality. | Depends on the Wi-Fi Direct signal | Adaptive. | Compressed. |
A unique feature of the Chromecast is the ability to “throw” content from specific applications. For example, while on YouTube, you can click on the broadcast icon and send the video to the TV, while continuing to use the phone for other tasks.
Why Google Home can't see TV?
Broadcast from Apple devices (AirPlay)
Owners of iPhone and iPad are no less fortunate: modern Xiaomi TVs support the AirPlay 2 protocol. This allows you to broadcast the screen or media from Apple devices natively, without installing additional software on the TV.
To activate, you need to go to your TV settings, find the "Apple AirPlay and HomeKit" section, and enable this option. On an iPhone, you just open the "Control Point", click on the "Screen Replay" button, and select your TV from the list. The system can request the code that will appear on the TV screen for the first pairing.
AirPlay transmissions are generally better than standard mirroring methods, thanks to efficient video coding, but AirPlay requires a powerful Wi-Fi channel to run, and if the router is old or overloaded, the image may slow down.
⚠️ Warning: AirPlay is sensitive to firewall settings on the router. If you can't connect, try temporarily disabling customer isolation AP (AP Isolation) in wireless network settings.
Third-party broadcast applications
If standard methods don't work or advanced features are needed, third-party solutions come to the rescue. Google Play and Mi Store have a variety of applications, such as Web Video Caster, Cast to TV or LocalCast, that allow you to stream not only the screen, but also files from local memory or links from the browser.
The way these programs work is to install the server part on the TV (if required), or use the TV's built-in reception protocols, so you open a video file in the app on your phone, select the output device, and enjoy watching, which is a great way to get around the limitations of DRM or formats that the built-in player doesn't support.
💡
Use casts-enabled browser apps if you want to bring videos from a site that doesn’t have an official Smart TV app to your TV. This often works better than mirroring the entire screen.
Some users prefer to install universal clients on the TV, such as AirScreen, which emulates AirPlay, Google Cast and Miracast receivers, making the TV visible to any device, even if the factory support for some protocols has been cut off by the manufacturer.
Addressing problems and delays
Despite the technology, wireless broadcasting can be problematic, the most common being audio and image desynchronization or periodic friezes, often caused by overloading the Wi-Fi channel by neighbouring routers, in which case switching to a less busy frequency or channel helps.
If you notice that your mouse cursor (when using your phone as a touchpad) or your game movements are late, try lowering the output resolution. In the phone’s live streaming settings, you can sometimes choose 720p quality over 1080p, which will significantly reduce network load and reduce latency.
💡
The stability of the broadcast depends on the quality of the Wi-Fi signal and the absence of interference in the air, not on the power of the TV itself.
In cases where there is no sound at all, check the audio output settings in the application itself, which is broadcasting. Sometimes the default system continues to output sound through the speaker of the phone, even if the video is going to the TV, and it is worth checking whether the TV has set the "Hearphones" mode in the audio settings.
