Modern multimedia capabilities allow instantaneous streaming of content from a mobile device to a large display, turning a normal viewing into a real cinema. Owner of Xiaomi Smart TV or Mi TV Stick consoles often faces the need to display photos, videos from a gallery or even smartphone gameplay. This is especially true for those who prefer watching movies through mobile applications of streaming services, but want to enjoy quality at a diagonal of 43 inches or more.
Screencasting (or screencasting) can be done in a number of ways, each with its own hardware and technical specifications. Depending on your TV model and the Android version of your smartphone, methods can range from built-in wireless features to physical cables, understanding these differences to avoid image delays and audio desynchronization.
In this article, we will take a look at how to project your phone screen onto a Xiaomi TV without using third-party complex settings, and we will also look at advanced options for gamers and professionals. You will learn how to set up Miracast, use the Google Cast protocol, and which cables will ensure maximum connection stability.
Wireless Image Transfer Technologies: Miracast and Chromecast
Before you start setting up, you need to understand the basic technologies that Xiaomi devices use to receive video. The main standard for Android devices is Miracast, a technology that allows you to transfer images and sound directly from your phone to your TV without having to connect to the Internet using only a local Wi-Fi network or a direct Wi-Fi Direct connection, which provides high data transfer speeds and minimal latency.
The second key technology is Google Chromecast built-in, which is often embedded in modern smart devices. TV Unlike simple screen cloning, this protocol allows content from specific applications (like YouTube or Netflix) to be streamed in high quality while the phone can be used for other tasks. DLNA It also supports media transfer, but it is less convenient for full system interface broadcasting.
⚠️ Warning: For Miracast and Chromecast wireless technologies, it is critical that both devices are on the same subnet.If your router distributes a network at 2.4 GHz and 5 GHz with different names (SSID), Make sure your phone and TV are connected to the same frequency, preferably 5GHz to reduce delays.
The choice of method depends on your goals: if you want to show a presentation or play a mobile game on a large screen, Miracast is better. For watching videos from online cinemas, the best solution will be the built-in Chromecast, which takes the load of decoding video on itself, saving battery power.
Equipment preparation and network inspection
Successful screen projection is impossible without proper infrastructure pre-preparation.The first step is to check the software version of your Xiaomi Mi TV. Manufacturers regularly release updates to improve the stability of wireless modules. Go to Settings menu → About TV → System Update and make sure the latest version is installed.
Next, make sure your router is capable of streaming high-definition video. 1080p or 4K requires a stable channel with a bandwidth of at least 20-30 Mbps. If other devices are actively downloading files or watching videos at the time of broadcasting, the picture quality on the TV may deteriorate, artifacts or “squares” will appear.
It is also worth checking the power saving settings on the smartphone. Aggressive charge saving algorithms can limit the background activity of the Wi-Fi module, which will cause the connection to break during the broadcast, it is recommended to temporarily turn off the energy saving mode or add the broadcast app to the exclusion list.
- 📶 Make sure your Wi-Fi TV module is running at 5GHz for maximum speed.
- 🔄 Restart the router before setting up to clear the connection cache.
- 📱 Turn it off. VPN on a smartphone, as it can block the detection of local devices.
- 🔋 Connect your phone to the charger as the screen broadcast consumes the battery quickly.
Broadcasting through the built-in "Translation" function in Android
The fastest way to display an image is to use a standard operating system feature. On most Xiaomi smartphones with MIUI or HyperOS shells, this tool is called Translation or Cast. It is based on the Miracast protocol and does not require additional software installation. To start, lower the notification curtain and find the appropriate icon.
Once activated, the phone will start looking for available devices within range. Your Xiaomi TV should appear on the list. If the TV is not displayed, check if the wireless display feature is enabled in the settings of the TV itself. It usually activates automatically, but in some regions it may require manual activation through the signal source menu.
☑️ Checklist of connection
Once you select a TV, you'll see a request for confirmation of connection on your smartphone screen, and you'll see a window on your TV screen asking if you want to allow access -- you can confirm the remote. From now on, everything that happens on your phone screen will be duplicated on your TV in real time. You just have to click on the icon in the notification curtain again to exit the broadcast mode.
It is important to note that when using this method, the phone screen should remain on. If a lock timeout is triggered, the broadcast can be interrupted, although modern versions of Android have learned to ignore the screen lock during the casting session.
Using the Google Home app for Chromecast
If standard broadcasting is unstable or you want to use more advanced management features, Google Home is a great solution.This is Google’s official tool for managing Chromecast-enabled devices. Many Xiaomi TVs have built-in support for this protocol, making them compatible with Google’s ecosystem.
Once you install and configure the app, it will automatically detect your TV on the local network, and you’ll need to select your device card and click the “Cast my screen” button on the interface, a method that often provides smoother picture and better synchronization of sound, especially when viewing content from browsers that don’t have a built-in Cast button.
| Parameter | Miracast (Translation) | Google Home (Chromecast) |
|---|---|---|
| Internet dependency | No requirement (local area network) | Required for initial setup |
| Delay (Latency) | Low (good for games) | Medium (depending on router) |
| Video quality | Depends on the Wi-Fi signal. | Adaptive (up to 4K HDR) |
| Background work | Phone screen is active | Other applications can be used |
⚠️ Note: When streaming through Google Home, make sure that your Google account has an action history enabled, otherwise some smart home and casting features may not work properly.
The advantage of using Google Home is that you can control volume and play directly from the widget on your smartphone, even if you folded the app, which turns the phone into a full-fledged remote control of multimedia content.
Broadcast from specific applications (YouTube, Netflix)
The best way to watch videos is to use the built-in Cast function inside the apps themselves. Services like YouTube, Netflix, IVI or Okko have a special button that allows you to send a video stream directly to the TV, in which case the phone acts only as a remote control, and the TV downloads the video itself over the Internet.
This solution is ideal because it takes the load off the smartphone processor and Wi-Fi module, and it plays home TV, supports HDR and Dolby Vision, if available, and has a much better picture quality than just screen cloning, where the compression of the stream can be noticeable.
What to do if the Cast button does not appear?
To start the broadcast, click on the Wi-Fi wave rectangle icon in the corner of the video player. Select your Xiaomi TV from the list. The video will start playing on the big screen, and the phone will have a control panel with the ability to switch tracks, adjust volume and subtitles.
Interestingly, this method allows you to pause and exit the app to respond to messages or check social media without interrupting the movie on TV, making it the most convenient way to watch content for a long time.
Wired connection through HDMI-cable
For situations where maximum stability and no delays are important (e.g. mobile gaming), wireless technology may not be suitable, in which case wired connectivity saves. However, simply plugging a USB-C cable into the HDMI port of a TV is not enough - your smartphone must support video output technology.
Xiaomi flagship models (Mi 10, Mi 11, Xiaomi 12/13/14 Pro) are often equipped with a USB 3.1/3.2 port with support for the DisplayPort Alt Mode standard. This allows you to transmit a video signal through the USB-C to HDMI adapter. Budget models (Redmi Note series) usually have a USB 2.0 port that can not transfer video, and for them this method will not work without the use of special adapters with DisplayLink technology.
Required equipment for wired connection:
1. USB-C to HDMI cable (active adapter).
2. TV with free HDMI port.
3. (Optional) External power for the adapter.When you connect the cable, the TV will automatically switch to the corresponding signal source. The image can either mirror the phone screen or, with support for Desktop Mode (similar to Samsung DeX, but in Xiaomi implementation this is less common and depends on the version of MIUI), deploy the interface in the form of a computer desktop.
💡
Use a quality cable no longer than 2 meters long. Cheap long cables often fail to transmit a 4K or even 1080p signal, resulting in screen flickering or no image.
Solution and optimization of quality
Even with the right setup, there can be technical failures. One of the common problems is to desynchronize sound and video. If the actors' lips are not moving in the beat of their voice, try to find the settings on the TV for "Audio delay" or "Lip Sync" and tweak it. Also, switching the audio output from "Auto" to "PCM" helps.
If the image is twitching or low resolution, check the load of the Wi-Fi channel. In apartment buildings, the air can be jammed with neighbor signals. Try changing the router's settings to a freer channel or force the devices to switch to the 5 GHz band, which is less prone to interference.
- 🛑 Problem: TV can't see phone.Solution: Reboot both devices and router.
- 🎨 Problem: Not full screen (black boxes) Solution: Press Format or Aspect Ratio on the TV remote and select Screen size or 16:9.
- 🔇 Problem: There's a picture, but there's no sound. Solution: Check if the Bluetooth headphones are connected to the phone that intercepts the audio stream.
⚠️ Note: For long-term broadcast of heavy games or videos 4K This can cause trottling and jerking images, remove the case from the phone or allow cold air to flow to the device.
💡
The stability of wireless broadcasting is 90% dependent on the quality of your Wi-Fi router and the absence of interference in the air, not just on the characteristics of the TV.
Final recommendations and selection of the best method
So to sum up, the way you project your screen is very much a function of your own. The Miracast feature is the perfect way to show your friends photos or present documents quickly, it doesn't require the Internet, it works fast, and you can use the casts from apps or Google Home to get the best picture quality.
Gamers who value every millisecond of response should consider a wired option if their smartphone model supports it. Owners of older routers may need to consider upgrading network equipment to unlock the potential of Xiaomi’s modern 4K TVs.
Don’t be afraid to experiment with resolution and frame rate settings. Smartphone + TV opens up new horizons for multimedia, turning the living room into a center of entertainment.
