Xiaomi’s modern Android TVs offer users a wide range of multimedia experiences. Xiaomi’s 4S 43 is no exception, offering built-in support for Google Chromecast technology, which allows content to be streamed directly from mobile devices, tablets or laptops to the big screen without the need for additional cables or external adapters.
However, despite the built-in nature of the technology, many users face difficulties in the first run. Often the problem lies not in the hardware, but in the software settings or firmware version. The built-in Chromecast on Xiaomi 4S 43 activates automatically when you properly configure Wi-Fi and update the system to the current version. In this guide, we will discuss all the stages of preparation and activation in detail.
It's important to understand that for a function to work, all devices must be on a single network. If you just purchased a TV or reset, you'll need to go through the initial configuration. We'll look at both standard on-boarding methods and solutions to common problems you may encounter in the process.
Compatibility check and preliminary requirements
Before you start setting up the broadcast, you need to make sure that your equipment meets the necessary requirements. The Xiaomi Mi TV 4S 43 is based on the Android TV platform, which guarantees native support for Google protocols. However, for the correct operation of the Cast function, you need to comply with a number of conditions, ignoring which can lead to connection errors.
First of all, make sure the TV is connected to the Internet. High-resolution video (Full HD or 4K) requires a stable connection. It is recommended to use 802.11ac (5GHz) Wi-Fi standards, as they provide more bandwidth compared to the 2.4GHz bandwidth. If the router is far away, it is better to use a wired connection via a LAN port.
It is also critical that the mobile device or computer from which the broadcast is planned be connected to the same Wi-Fi network. Separation of networks (such as the guest network and the main network) is often the reason why devices do not see each other.
- 📺 Operating system of the TV: Android TV (8.0 and higher).
- 📶 Network: Unified Wi-Fi network for TV and smartphone (preferably 5 GHz).
- 📱 Source device: Android or iOS smartphone, tablet or laptop with Chrome browser.
- 🔋 Power: Stable power supply without frequent network interruptions.
⚠️ Note: If your router distributes 2.4 GHz and 5 GHz networks under different names (SSID), Make sure to connect both the TV and the phone to the same frequency, otherwise it may not be possible to detect the devices.
Updating the TV software
Often built-in features like Chromecast built-in may not work properly on legacy firmware. Xiaomi developers regularly release updates that fix network stack bugs and improve compatibility with Google services. So the first step after connecting to the Internet should be to check for updates.
To do this, go to the main menu of the TV and find the settings section. The path may vary slightly depending on the regional version of the firmware, but it usually looks like Settings → About TV → System Update. If the system suggests installing a new version, agree. The process can take anywhere from 10 to 30 minutes, during which the TV can restart.
Once updated and turned on again, the TV will automatically register on Google's network, at which point the hidden services responsible for receiving the Cast signal are activated. If you miss this step, the feature may appear unavailable or work with delays.

💡
Before the start of the firmware update, it is strongly recommended to disable all unnecessary USB-devices, leaving only the remote to avoid driver conflicts during the reboot.
Setting up a network and Google account
The Xiaomi and Google ecosystem is based on proper authorization. Without a Google account, many services, including YouTube, Netflix and the Chromecast itself, can work with restrictions or not at all. On a Xiaomi 4S 43 TV, you can log in through the standard Android TV menu.
When you first turn on, the system will prompt you to log in. If you missed this step, go to Settings → Accounts and Login → Add an account. Enter your details or use the code displayed on the screen to log in via your mobile device. This is the most convenient way, since it does not require you to enter a password using the remote.
Once you have successfully logged in, check the date and time settings. They must be synced to the network (Settings → Device → Date and Time → Automatically). Dissynchronizing the time even for a few minutes can cause security certificate errors, causing the Cast protocol to fail.
| Parameter | Recommended value | The impact on Chromecast |
|---|---|---|
| Date and time | Automatically (over the network) | Critical for SSL-certificate |
| Language and region |
Instructions for launching broadcasts from Android
After all the preparatory steps, you can move to the direct use of the function. On Android devices, the process is as simple as possible, since the technology is built into the system. You do not need to install additional applications for basic screen broadcasting.
Open the notification curtain on your smartphone (swipe top-down) and find the Broadcast (or Cast) button. If the icon isn't available in quick access, click on the menu edit icon (usually a pencil or three dots) and add the Translation widget to the panel. Your Xiaomi TV 4S 43 should appear on the list of available devices.
Click on the TV name. You may see a request for permission to connect on the TV screen. You can confirm it with the remote. You will now have your smartphone screen duplicated on the TV. To stop the broadcast, click on the button in the notification curtain again or select "Disable".
☑️ Translation launch algorithm
Many apps, like YouTube, Netflix, or Vimeo, have their own Cast button inside the player interface. This is the preferred way, since it allows you to control playback from the phone without draining its battery of active video streaming (as opposed to mirroring the entire screen). Just click on the icon of the rectangle with waves in the corner of the video and select the TV.
Using Chromecast with iPhone and iPad (iOS)
Apple device owners can also take advantage of their TV's capabilities, although the process is slightly different due to operating system differences: Xiaomi's native AirPlay feature doesn't work on all models or requires separate activation, so it's best to use the Chromecast protocol through apps to guarantee a result.
To stream content from apps (YouTube, Google Photos, Chrome browser), the algorithm is similar to Android: look for the Cast icon in the program interface. However, if you want to broadcast the entire screen of the iPhone (mirror), this will not work with standard means, since iOS uses AirPlay. In this case, you will need to install third-party applications on the TV itself from the Google Play Store, such as AirScreen or Receiver for AirPlay.
Once you install this app on Xiaomi, run it. On your iPhone, open Control Point (swipe down from the top right corner or bottom up, depending on the model) and click Screen Replay. Select the app running on your TV, which will bypass protocol restriction and display the image from iOS to Android TV.
⚠️ Note: When using third-party AirPlay emulator apps on Android TV Possible delay of image (lag) to 1-2 It's not critical to watch video, but it can be noticeable for dynamic games.
Working with Google Chrome on PC
The Xiaomi 4S 43 TV is a great second monitor for your computer, and you need to have Google Chrome installed on your PC, which allows you to display tabs, presentations, or even the entire desktop on the big screen.
Open the Chrome browser on your computer. Click on the three dots in the top right corner of the menu and select Cast. The available devices will be searched for. If the TV isn't found, make sure that the PC and TV are in the same time zone and they're on the same network.
In the source selection window, you can switch from the tab to Translate Desktop or Translate File, which is useful for showing hard drive photos or PowerPoint presentations. The sound will also be transmitted to the TV if you select the appropriate option at the source.
chrome://cast/#device-listBy typing this command into the Chrome address bar, you’ll be taken to the hidden Cast debugging page, where you can see the technical details of the connection if the standard search doesn’t work.
💡
Broadcasting through the Chrome browser allows you to use the TV as a wireless monitor for any tasks, including working with documents and surfing the web.
Solving Common Connection Problems
Even if you follow all the instructions, you can have situations where devices can't see each other or communication is constantly interrupted, most often this is due to router settings or application cache, the first thing you can do is reboot your router, TV, and smartphone, which solves 80% of network protocol problems.
If the problem persists, check your antivirus or firewall settings on your computer. They can block local connections needed to run the Chromecast. DNS-server in the settings of the TV Wi-Fi to public Google addresses (8.8.8.8 and 8.8.4.4), which often improves communication with Google servers.
As a last resort, you can try to clear the data of the Google Cast Receiver app on the TV itself. To do this, go to Settings → Apps → All Apps → Google Cast Receiver → Clear the data. After that, you will need to add the TV again to the Google Home app on your smartphone.
- 🔄 Restart the router and all devices.
- 🔍 Check if the “Guest Network” mode on the router is turned on.
- 🗑️ Clear the cache of Google Home and YouTube.
- 📶 Make sure that the Wi-Fi signal on the TV is stable (at least) 2-3 division).
