Owners of modern Xiaomi equipment often face the desire to expand the functionality of their TV, adding to it the ability to stream content from mobile devices. Chromecast remains one of the most popular ways to do this, turning a regular screen into a multimedia center. However, the integration of Google’s device with the shell MIUI TV or Android TV from Xiaomi has its own nuances that must be considered for stable operation.
The process of pairing may seem obscure due to the operating system and network settings of the router. In this article, we will look at all the steps from choosing the right HDMI port to fine-tuning the Wi-Fi network to minimize delays. You will learn why sometimes the built-in Chromecast is not visible to the phone and how to get around the limitations of the security protocol.
Whether you’re using an external dongle adapter or an integrated streaming feature, the right sequence of actions will save you time.We’ll look at both wired and wireless methods, and we’ll also address common buffering and image quality issues.
Preparation of equipment and choice of interface
The first step is to physically connect the device. Most modern Xiaomi Mi TV models come with multiple HDMI ports, but it is critical to choose the right connector to work with the Chromecast.Preference should be given to the HDMI 1 or HDMI 2.0 port, which is often labeled ARC/eARC, although this is not always crucial for a video signal, but provides better compatibility with audio systems in the future.
If you use an external Chromecast adapter (e.g. Chromecast with Google) TV), It's not recommended to power the device from USB-The TV port itself, as the 0.5 Ampere voltage is often not enough to run smoothly, leading to constant reboots.
⚠️ Note: When connecting an external Chromecast, make sure the cable is connected. HDMI They don't get squeezed by the body of the TV if it's hanging on the wall, which is a common cause of loss of signal and artifacts on the screen.
For Xiaomi’s built-in Smart TV features, it’s important to check the operating system version. Go to Settings → Device → Version and make sure the software is updated to the latest available version. Older versions of Android TV may have vulnerabilities in device discovery protocols on the local network.

Setting up a Wi-Fi network for stable broadcasting
The quality of the broadcast depends on the configuration of your wireless network. Xiaomi and Chromecast devices should be on the same subnet. If your router broadcasts two networks (2.4 GHz and 5 GHz) under different names (SSID), make sure that both the phone and the TV are connected to the same frequency, preferably 5 GHz, as it provides more bandwidth for video in 4K.
In some cases, routers have an "AP Isolation" feature that prevents devices on the network from seeing each other, which blocks Chromecast, so you need to log into your router settings (usually at 192.168.0.1 or 192.168.1.1) and find the Wireless Settings → Advanced option to turn off the access point isolation.
You also need to look at the Wi-Fi channel. If you have a lot of neighborhood networks around, the router's automatic channel selection may be suboptimal. Use the analyzer apps on your smartphone to find the free channel, and lock it into your router settings manually, which will reduce packet loss when streaming.
💡
To stream video in 4K HDR resolution, the Wi-Fi connection speed must consistently exceed 25 Mbps. Check the speed on your TV through the Speedtest app before setting up.
Instructions: Connecting through the Google Home app
The main management tool is the Google Home app, available for Android and iOS. After you install and log in to your Google account, click the + button in the top corner and select Set up your device.
Then the app will start searching for devices. Make sure that the Chromecast built-in app or similar system application for broadcasting is open on the Xiaomi TV.
Enter the code in the app on your smartphone. Once confirmed, the pairing process will begin, during which the Wi-Fi settings will be copied from the phone to the Chromecast, at which time the screen can go out and turn on - this is normal behavior when switching HDMI modes.
| The adjustment phase | User action | Expected output |
|---|---|---|
| Searching device | Click "Add" in Google Home | Displaying the Chromecast logo on TV |
| Code check | Comparison of codes on phone and TV | Confirmation of convergence of figures |
| Update of the PO | Waiting for completion (automatically) | Reboot the adapter or module |
| Linking services | Selection of accounts (Netflix, YouTube) | Readiness for content broadcasting |
Using the built-in Chromecast in Xiaomi TV
Many modern Xiaomi TVs already have built-in support for the technology, known as Chromecast built-in. In this case, buying a separate dongle is not required. However, on global firmware, this feature is sometimes hidden or unstable due to regional restrictions.
To activate the broadcast, open an app on your smartphone that supports Cast (such as YouTube or Netflix) and click on the broadcast icon. If the TV doesn't appear in the list, check if the feature is enabled in the TV settings: Settings → Apps → Chromecast built-in → Enable.
Some versions of the PatchWall shell require you to allow access to the local network. Go to Settings → Privacy and make sure that the system applications broadcast is allowed to access local devices. Without this, the phone simply “will not see” the TV, even if you are on the same network.
⚠️ Note: Embedded Chromecast on Xiaomi TVs may conflict with active VPN-If the broadcast is interrupted, try to temporarily turn off the connection. VPN or add exclusion rules for local IP-address.
Alternative methods: Miracast and phone screen
If the classic Chromecast doesn’t work or requires specific content, you can use mirroring technology. In Xiaomi, this feature is often called Wireless Display or Broadcast, which allows you to display everything that happens on the smartphone screen, including menus and games.
To activate on your TV, go to the apps section and start Wireless Display. On an Android smartphone, in the notification curtain, find the Translation, Smart View or Projection button. On your iPhone, use Screen Replay through Control Point, but make sure the TV supports AirPlay 2 (many new Xiaomi models do this).
Mirroring puts a lot of strain on the phone’s processor and Wi-Fi channel, so it can delay the image (lag) and reduce the quality of the picture compared to the native Chromecast.
Why is the sound delayed when mirroring?
Problem Solving: The device is not found or is reset
One of the most common problems is when the phone stops seeing the Chromecast after the router restarts, which is because the device may have been assigned a new one. IP-address and cache DNS The solution is simple: turn off the TV completely (plug out the socket for 10 seconds) and restart the router.
If the image twitches or is low resolution, check the resolution settings in the Google Home app. Go to the Chromecast device settings and select Settings → Screen → Resolution. Try changing the frame rate from 60Hz to 50Hz (or vice versa), as some Xiaomi panels work better with a certain refresh rate.
Also worth mentioning is the problem with antiviruses on routers (like Keenetic or Asus with built-in antivirus) that can block ports used by the mDNS protocol, which is responsible for detecting devices, add your TV and phone to the list of trusted devices, or temporarily turn off traffic filtering for diagnostics.
💡
90% of connection problems are solved by restarting all three participants in the process: router, TV and smartphone, strictly in this order.
Optimizing the quality of image and sound
To achieve the best picture quality, it is important to properly configure the display settings. From the Xiaomi TV menu, go to Settings → Image and select Mode Mode Mode for Mode Mode Mode or Mode Mode for Reduced Delay. Disable all noise reduction and dynamic contrast functions, as they can contribute artifacts when streaming.
As for sound, if you have external acoustics connected via optical output or ARC, make sure that the Chromecast settings choose the Pass-through or Dolby Digital output format, if your system supports it. Otherwise, the sound will be decoded by the TV, which can lead to loss of quality or desynchronization.
Clean the cache of the Google Home app and the Chromecast system app on your TV regularly, and over time, data accumulates that can slow the interface response, and you can do this in Settings → Applications → Application Management → Chromecast built-in → Clear the cache.
