Xiaomi’s modern smartphones have powerful multimedia capabilities that turn a regular TV into a center of entertainment.Basing images from a mobile device to a large screen is a convenient way to show presentations, watch high-resolution movies or play mobile games with better graphics. Users often face the need to share content, and the built-in MIUI or HyperOS features provide several effective tools for this.
Connection can vary depending on the year your TV is released and the version of your smartphone operating system. There are wired and wireless methods, each with its own advantages in terms of signal stability and picture quality. Wireless data has become the de facto standard thanks to Miracast and Google Cast technologies that do not require additional cables.
In this guide, we will take a look at all the current ways to sync your screen, learn how to set up a connection through a standard menu, what apps to install for older TV models, and how to solve typical connection problems.
Preparing devices for synchronization
Before setting up, make sure that both devices are on the same local Wi-Fi network. This is a critical condition for most wireless broadcast protocols. If the router is broadcasting at 2.4 GHz and 5 GHz, it is advisable that both the phone and the TV be connected to the same frequency to avoid device detection problems.
On Smart TVs, the signal reception function often needs to be manually activated. In the TV settings menu, look for sections called Screen Mirroring, Broadcast, Smart View or Wireless Display. Some Samsung or LG models require you to run the corresponding app from the Source/Input list to make the TV visible to search.
⚠️ Note: If your router is set up with customer isolation (AP Isolation, devices won't see each other even on the same network.
Check the operating system version on your Xiaomi smartphone.The menu functionality may differ on older versions of MIUI and the new HyperOS. Also make sure the phone has Bluetooth and geolocation modules enabled, as these are sometimes used for initial handshake devices.
☑️ Checking before connection
Use of the built-in Translation function in MIUI
The easiest and fastest way to display an image is to use a system utility, which is called Translation or Cast in the MIUI shell, and is based on the Miracast protocol, which supports most modern TVs without the need to install additional software.
To start, open the notification curtain control center and find the Translation icon. If the icon is not available in quick access, go to Settings → Connection and Sharing → Broadcast. Once the function is turned on, the phone will start scanning available devices within network range.
When the name of your TV appears on the list, click on it. You may see a request for confirmation of connection on the TV screen — you can agree with the remote control. The image from the phone will instantly appear on the big screen. The quality of transmission depends on the power of the Wi-Fi signal and the distance between the gadgets.
The Hidden Function of the Developer
It is important to note that when using this method, the phone screen is completely duplicated, which means that any notifications, calls or messages will be visible to everyone in the room. For privacy, it is better to turn on Do Not Disturb mode before you start watching.
Broadcasting via Google Home and Chromecast
If your TV supports Chromecast built-in technology or has an Android TV attached to it, the best solution is to use the Google ecosystem, which allows for more stable high-resolution video transmission and allows you to control playback directly from your smartphone.
Download and install the Google Home app from the Play Market Store. Launch it and log in to your Google account. The app will automatically find Chromecast devices or Cast-enabled TVs on your Wi-Fi network.
- 📺 Select your TV from the list of available devices in the app.
- 🖥️ Click the “Cast screen” button in the lower menu.
- ✅ Confirm the action if a code or request appears on the TV screen.
- 🎮 Enjoy content using your phone as a remote control.
The advantage of this method is that it is less dependent on smartphone performance, as part of the decoding can be taken over by the TV.In addition, Google Home allows you to broadcast the sound separately if the TV is connected to an external speaker system.

Broadcasting videos from apps (YouTube, Netflix, IVI)
Many popular streaming services have their own image output mechanism, which often works better than the system broadcast. YouTube, Netflix, IVi or Kinopoisk applications use DIAL technology or built-in Cast protocol.
To use this feature, open a video on your smartphone and find the broadcast icon (a rectangle with waves in the corner). Click on it and select your TV. Unlike duplicate screens, in this case the phone is only a remote control, and the video is downloaded by the TV directly from the Internet.
This approach has some undeniable advantages: first, the battery of the smartphone is minimal, because the screen can be extinguished; second, the quality of the video adapts to the capabilities of the TV and the speed of the Internet, bypassing the limitations of the Wi-Fi channel between the phone and the router.
⚠️ Note: If the broadcast icon does not appear, make sure that the accounts in the app on your phone and on Smart TV (if there is an input, the devices are in the same subnet.
Some applications may require codecs or the program itself to work properly with new TV models. If the broadcast is interrupted, try restarting the router, as streaming requires a stable channel.
Using third-party applications for complex cases
There are times when standard methods don’t work, like an old-fashioned TV, protocol incompatibility, or Xiaomi firmware errors, and the universal translation apps available on Google Play come to the rescue.
One of the most popular solutions is the Web Video Caster or AirScreen app, which allows you to emulate the operation of various protocols (AirPlay, DLNA, Chromecast) and transfer content even to non-Smart TVs through consoles or old Android boxes.
- 📲 Install the translator app on the phone and, if necessary, companion app on the phone TV.
- 🌐 Open the browser inside the application and go to the site with video.
- 📡 Press the “Play” button and select the device to output.
- ⚙️ In the application settings, you can change the bitrate or codec to improve compatibility.
These apps often have paid versions with advanced functionality, but the basic features are usually enough for home use, and are especially useful for streaming local video files that are not supported by the TV's built-in player.
