Modern Xiaomi TVs have long ceased to be just screens for receiving an air signal, becoming powerful multimedia centers with the Android TV operating system. One of the key features that is often mentioned in the specifications, but not always clear to the average user, is the built-in Chromecast technology. Many owners ask what Xiaomi Chromecast is and why it is needed if the TV already has a Smart TV. The answer lies in the convenience of wireless content transfer.
Chromecast built-in is a software module built directly into the TV operating system that allows you to stream videos, music and images from a smartphone, tablet or laptop to the big screen without using cables. Unlike external consoles, this feature does not require separate power supply or connection to the HDMI-port, as it is a native part of the Android interface TV. This turns your TV into a full-fledged multimedia receiver from anywhere on the local network.
The technology works over Wi-Fi, creating a bridge between your mobile device and your TV. You don’t have to mirror the phone screen, which often leads to battery drain and lower picture quality. Instead, the TV downloads content on the link you send it, ensuring maximum playback quality up to 4K HDR. This is especially true for owners of Xiaomi Mi TV Stick, Android TV Box and modern Mi TV series P1, A2, Q1.
Principle of operation and technical features of technology
At the heart of Chromecast built-in is the Google Cast protocol, which uses a local Wi-Fi network to transmit control commands. When you click the broadcast button in the app on your smartphone, your device sends a link to the TV to the video stream and control commands (pause, rewind, volume). The TV itself, with its own processor and network module, buffers and plays content directly from the Internet.
This means that your smartphone or tablet is just a remote control, so you can log out of the YouTube app on your phone, answer a call, or even turn off the screen of your mobile device, and the video on your Xiaomi Mi TV will continue to play without interruptions, which greatly reduces the load on your mobile device and allows you to use your phone for other tasks while watching a movie.
⚠️ Attention: It is critical that both devices, a smartphone and a TV, are on the same Wi-Fi network to work properly, and users often face problems when the phone is connected to guest Wi-Fi or using mobile Internet. 4G/5G, While the TV is running through the main router.
The technology supports a wide range of codecs and formats, including H.264, VP9 and HEVC, which ensures compatibility with most streaming services. The bandwidth of your router plays a key role here: for stable broadcast in 4K, the 5 GHz network is recommended, which provides higher data transfer speeds and is less susceptible to interference from neighboring networks.
Differences between the built-in Chromecast and the external console
Many users confuse the Chromecast built-in feature in Xiaomi TVs with the Google Chromecast external device, which connects via HDMI. Although the software part is identical, the physical implementation and capabilities vary significantly. The built-in module does not require additional space behind the TV and a separate power source, which simplifies the setup system.
External devices such as Chromecast with Google TV often have a more powerful processor and its own operating shell with recommendations for content on the home screen. In Xiaomi TVs, the interface may be slightly modified by the manufacturer, but the basic functionality of receiving broadcasts remains the same. However, external dongle devices sometimes receive updates faster than embedded modules in TV.
The important difference is that support for wireless standards is also important: the latest generation of external consoles often support Wi-Fi 6 and the Thread standard for the smart home, whereas embedded TV modules can be limited to Wi-Fi 5 (ac) or even Wi-Fi 4 (n) in budget models, which can affect the stability of high-resolution streaming video.
Below is a comparative table that helps you understand the nuances:
| Characteristics | Chromecast built-in (in Xiaomi) | External Google Chromecast |
|---|---|---|
| Connection | Built into Android TV system | HDMI port + USB power |
| DU remote | The TV remote is used. | You need a separate remote or phone. |
| Interface. | PatchWall or pure Android TV | Google TV (recommended feed) |
| Updates | Depends on Xiaomi. | Direct from Google |
Compatible devices and applications for broadcasting
The Chromecast ecosystem spans millions of applications, making the Xiaomi TV a universal display for all content, with support for Android and iOS operating systems, as well as the Google Chrome browser on Windows, macOS and Linux computers, meaning you can stream content from almost any modern gadget.
Among the most popular applications that support the Cast feature, video services like YouTube, Netflix, Disney+, Hulu and local platforms are worth noting. For owners of Apple equipment, it is important to know that many applications support AirPlay 2, but Chromecast often provides more stable work on mixed networks, where devices of different brands are used.

Step-by-step instructions for setting up and connecting
The process of activating and using the built-in Chromecast on Xiaomi TVs is as simple as possible and does not require complex pre-preparation, the main requirement is the presence of a working Wi-Fi network and the Google Home application installed on a mobile device for initial diagnosis, although often the system works right out of the box.
To start, make sure your Xiaomi TV is connected to the internet. Check this by running any built-in app like YouTube. Then take the smartphone you'll use as a remote and connect it to the same Wi-Fi network. The difference in even one letter in the network name (like 2.4GHz and 5GHz) can sometimes cause visibility problems, so ideally use one frequency.
Next, open the app you want to stream content from. Find the broadcast icon — the rectangle with the waves in the corner. Click on it and select from the list your Xiaomi Mi TV. If the device is not located, try restarting the router or checking the firewall settings on the router, which can block local device detection.
In some cases, you may need to confirm your connection on your TV screen. Google Cast security will ask permission to connect the new device. Use the TV remote to press Accept or enter the code displayed on the screen into the app on your smartphone.
⚠️ Note: If the TV is not displayed in the list of available devices, check if the router is not enabled mode "Customer isolation". AP» (AP Isolation: This feature prevents devices on the same network from seeing each other, which completely blocks Chromecast from working.
Solving Connection Problems and Errors
Despite the technology's proven provenness, users can experience a variety of bugs, and one of the most common problems is audio and video desynchronization or constant buffering, which often indicates an unstable Wi-Fi signal. In this case, it is recommended to move the router closer to the TV or use a wired LAN-Connection if Xiaomi model supports Ethernet.
Another common problem is the black screen when trying to stream videos from a browser or specific applications. DRM-Some sites prohibit the broadcast of protected content through the “Translate tab” function, requiring the use of a native app with support for Cast.
Also worth mentioning is the font encoding problem when translating browser tabs. If the text on the site is displayed incorrectly or instead of "crazy" try to change the page zoom in the browser or use the "Translate full screen" mode instead of a separate tab, this will switch the method of encoding the video stream.
- 🔄 Reboot: The most effective method is to completely shut the TV out of the socket for 10 seconds, not just in standby.
- 📡 Frequency change: Switching between 2.4 GHz and 5 GHz could solve connection speed and stability issues.
- 📱 App Update: An outdated version of Google Home or YouTube app on your phone is often the cause of crashes.
Using Chrome Cast for games and presentations
Chromecast is not just limited to video consumption; it can be used effectively to show presentations, photos, or even games. When you stream your screen via Chrome Cast, your TV becomes your second monitor, opening up new possibilities for Android TV.
It is important for games to understand the delay limits (input lag). When transmitting images from a phone in real time, the delay can be from 100 ms or higher, making it impossible to use dynamic shooters or races. However, for turn-based strategies, card games or quizzes, this is a perfectly acceptable option, allowing you to play a large company using the phone as a controller.
In a business environment or for learning, this feature is indispensable. You can open a presentation on a tablet and broadcast it to the big screen without having to search for HDMI adapters. Support for multi-touch gestures when broadcast from some devices allows you to control slides directly on the smartphone screen while the audience sees the result on the TV.
To activate screen mirroring mode (not to be confused with streaming videos from apps) on Android devices, the "Translation" feature in the notification curtain or the "Smart View" / "Cast" menu is often used, depending on the phone manufacturer. On iPhone, this feature is called "Screen Replay" and also supports the protocol if the Xiaomi TV is properly configured.
