Xiaomi’s modern smart TVs provide users with a wide range of multimedia capabilities, with wireless content transfer taking center stage. A feature known as Chromecast built-in, which allows instant video, music and photos from a mobile device to a large screen without the need for additional cables, especially for Android and iOS smartphone owners who want to enjoy high-resolution content.
However, despite the seemingly simple process, users often face technical nuances that block the broadcast from running. An unstable connection, outdated software or incorrect router settings can turn a simple procedure into a puzzle. In this article, we will discuss in detail how to run a chromcast on a shaomi TV, eliminating common errors and ensuring stable synchronization of devices.
The function depends on proper network environment preparation, and you need to make sure that your Mi TV or Mi Box has internet access and is on the same LAN as the control gadget, and ignoring this basic requirement is responsible for 90% of all failed connection attempts.
Compatibility check and equipment preparation
The first step to successful customization is to verify the hardware and software base of your device. Not all Xiaomi TVs have a built-in Chromecast module, especially earlier versions that run on the PatchWall shell without full Google certification. It is important to determine which operating system is installed on your device: Android TV or proprietary MIUI for TV.
If your TV is running a pure Android TV, Chromecast is built-in by default and does not require additional applications. In the case of the MIUI shell, you may need to install a special plugin or use third-party solutions to emulate signal reception. You can check the version of the software in the settings menu by selecting About TV or About.
It is also critical to make sure the router supports Wi-Fi 802.11ac or newer wireless standards for transmitting video to 4K without delay.Old routers running only at 2.4GHz may not be able to handle high-quality streaming video, causing buffering.
- 📺 Make sure the TV model is in the Mi series. TV Stick, Mi Box S or modern models with Android TV.
- 📶 Check that the router gives away a 5GHz network for a stable data stream.
- 📱 Install Google Home app on your smartphone if it’s not already integrated into your system.
⚠️ Note: Some regional versions of Xiaomi TVs may have the Chromecast feature software blocked, requiring third-party launchers or external consoles.
For users whose devices are not natively supported, there are alternative methods: you can use the TV's built-in browser to receive broadcasts or connect an external dongle, but for a full experience, you can better focus on devices with the Works with Google Assistant logo.
Set up a single Wi-Fi network for devices
The fundamental requirement for casting technology is to have both the signal source (smartphone) and the receiver (TV) on the same subnet, which means they must be connected to the same router, and it is a common mistake to connect the phone to 4G/5G mobile internet while the TV is running over Wi-Fi.
Modern routers often support dual-band, creating two networks with the same name (SSID) frequency-wise 2.4 GHz and 5 GHz: Devices must be connected to one of them, if your router splits those networks into different names (e.g. HomeWiFi and other devices). HomeWiFi_5G), Make sure that both devices are connected to the network with the console _5G maximum speed.
In corporate or hotel networks that require web page authorization, Chromecast often fails because of customer isolation, a problem that can be encountered at home if the Guest Network is enabled on the router.
To check the connection, go to the network settings on your TV. The path usually looks like this: Settings → Network and Internet → Wi-Fi. Here you will see the name of the active network and the signal level. If the signal is weaker than two divisions, the broadcast quality will be low.
- 🔌 Turn off mobile internet on your smartphone before setting up.
- 📡 Convince theikes that SSID Telephone and TV networks are identical.
- 🚫 Don’t use a guest Wi-Fi network to set up a smart home.
If the devices are on the same network but can't see each other, try restarting the router. DHCP-The server is overflowing and new devices are not getting the correct ones. IP-local address.
Activation of Chromecast function in the Xiaomi interface
Once network connectivity is provided, the TV-side receiver must be activated. In most cases, on Android TV, this feature is active by default, but requires confirmation at first start. The TV screen may be shown with a message that the new device is trying to connect.
To manually check status, go to the app menu and find the Chromecast built-in system app. If it's not in the installed list, it may be disabled. Go to Settings → Apps → Show all apps, search the Chromecast list and make sure it's enabled.
The screen resolution and refresh rate are important. For a comfortable viewing, it is recommended to set a resolution of 1920×1080 or 3840×2160 at 60 Hz. These settings affect how the image will be scaled during the broadcast.
☑️ Checking the activation of the service
Some users prefer to use the Guest mode, which allows you to broadcast content without connecting to a Wi-Fi network using ultrasonic signals, but for stable work at home, it is better to use the standard mode over the local network.
⚠️ Attention: If you are using VPN On a smartphone or router, the Chromecast function may not work, as the devices will be in different virtual locations. VPN before launch.
It's also worth checking your energy saving settings, if the TV goes to sleep too quickly, the connection may break, and set your sleep timer to 15 minutes or 30 minutes so that the system doesn't interrupt the background.
Launching broadcasts from mobile devices
The process of launching the broadcast varies depending on the operating system of your smartphone. On Android devices, the function is often built into the system. Just unlock the screen, open the quick swipe bar from top to bottom and click on the Broadcast or Smart View button (on Samsung), Broadcast (on Xiaomi).
For iPhone and iPad owners, the situation is a little more complicated, as Apple uses its AirPlay protocol. However, many modern Xiaomi TVs support AirPlay 2 natively. If this feature is not available, you need to use the Google Home app or third-party solutions such as Replica or Web Video Caster.
Let's look at the action algorithm through the YouTube app, because that's the most popular scenario: Open the video on your smartphone, click on the Chromecast icon in the corner of the player. Select your Xiaomi TV from the list. The video should start playing on the big screen.
Sequence of action:
1. Open content (YouTube, Netflix, photo).
2. Press the Cast icon (rectangle + waves).
3. Select the device "Xiaomi TV" or "Android TV".
4. wait for the connection and the beginning of reproduction.If you want to broadcast the entire screen of a smartphone (for example, to show a presentation or a game), use the system function “Screen Translation”, in which case the image from the smartphone will be duplicated on TV in real time, which can consume more battery power.
- 📲 For Android: Notification Panel → "Translation" button".
- 🍏 For iOS: Control Point → "Screen replay (if you have AirPlay) or Google Home app.
- 🎮 For games: Use low latency mode in your TV settings.
Solving Common Connection Problems
Despite the simplicity of the technology, users often encounter errors. One of the most common problems is "Device not found." This almost always indicates a network problem. AP (AP Isolation, which prevents devices within the network from sharing data.
Another common problem is desynchronizing sound and image or constantly buffering, which indicates a lack of channel bandwidth. Try to reduce the quality of video in the source application from 4K to 1080p.
If the broadcast is interrupted at certain intervals, check the firewall settings.The ports used for Chromecast (usually 8008, 8009, 8443) should be open to the LAN.
Hidden router settings for stability
In some cases, resetting the network settings on the TV helps. Go to Settings → Network → Reset your network settings. Then re-enter your Wi-Fi password, which clears the cache of network connections and eliminates conflicts. IP-address.
| Problem. | Probable cause | Decision |
|---|---|---|
| TV not visible on the list | Different Wi-Fi networks | Connect both devices to the same router |
| Black screen when connected | Codec incompatibility | Update the source application or change the video format |
| Sound delay (lag) | Wi-Fi channel overload | Switch to 5 GHz or reduce quality |
| Frequent communication gaps | Weak signal. | Close the router or use a Wi-Fi repeater |
Use of alternative casting applications
If native tools are unstable, third-party apps come to the rescue. One of the best solutions for Xiaomi owners is the Web Video Caster app, which allows you to stream videos directly from sites without browser restrictions, and has a built-in format converter.
For users who want to stream a screen from a computer (PC/Mac) to a TV, Google Chrome is a great browser. Open the browser menu (three dots), select Broadcast.. and select a tab or the entire desktop. Xiaomi TV will act as a wireless monitor.
Another powerful tool is the AllConnect app, which supports not only video, but also audio files and photos, and automatically scans the network and offers a list of available devices, including Mi TVs.
💡
Use the BubbleUPnP app to play local video files from your phone to your TV without loss of quality and transcoding.
When you first run, give you access to the local network and media, and without these permissions, the app won't be able to find the TV or access files.
⚠️ WARNING: When using free versions of third-party apps, beware of pop-up ads that may override the broadcast control interface.
For professional use, such as for presentations, you can use the Miracast protocol, which is also supported by many Xiaomi models. It provides lower latency compared to the Chromecast, which is important for interactive content.
Optimizing the quality of image and sound
Once the broadcast is successful, you should take care of the quality of the output signal. In the settings of the Xiaomi TV, go to Settings → Image. Select Mode Movie or Standard for the most accurate color reproduction. Bright Mode often distorts the colors and makes the picture unnatural.
Special attention should be paid to audio settings. If you are using an external speaker system via optical output or HDMI ARC, make sure that the Dolby Digital or Pass-through format is chosen in the audio settings, which will allow the TV to transmit the original audio stream to the receiver without decoding.
To reduce input lag when streaming games from your phone, turn on Game Mode in the image settings, which disables unnecessary post-processing effects, speeding up response.
💡
The quality of wireless broadcasting is 80% dependent on the stability of the Wi-Fi signal and the right frequency (5 GHz is preferred).
Remember to update your TV system software regularly. Xiaomi periodically releases patches that improve the stability of the Wi-Fi module and compatibility with new versions of the Chromecast protocol.
