Xiaomi’s modern Smart TV has become a central element of digital entertainment in many homes, offering impressive images and wide-ranging functionality. However, the diagonal of a smartphone, however advanced, often limits the enjoyment of watching movies, photos or surfing the web. Fortunately, the Android ecosystem and the branded MIUI TV shell make it easy to broadcast the contents of a mobile device to the big screen without unnecessary wires.
There are several proven ways to do this, each with its own characteristics and suits different use cases: You can use embedded broadcast protocols, third-party apps, or even cable connectivity to achieve the best quality. In this article, we will detail how to set up a connection, what nuances to consider, and how to avoid common latency or image quality issues.
Before you start setting up, make sure that both your smartphone and your TV are working correctly. Connection stability is directly dependent on the software version and the quality of your home network. We'll look at both the de facto wireless methods and the wired options for those who value maximum reliability.
Preparation of equipment and Wi-Fi network
The foundation for successful wireless broadcasting is the right LAN organization. Both devices must be on the same subnet, that is, connected to the same router. If you use a dual-band router, make sure that both the phone and the TV are connected to the same frequency, preferably 5 GHz, as it provides higher bandwidth.
Check the operating system version on your Xiaomi TV. Often manufacturers add support for new codecs and protocols with software updates. Go to the TV settings menu, select the About section and check for updates. A similar procedure should be done on a smartphone, especially if you are using a Xiaomi or Redmi model with a MIUI shell.
- 📶 Make sure the Wi-Fi signal is confident in the location of the TV to avoid image artifacts.
- 🔄 Restart your router before setting up if the network is unstable during the day.
- 📱 Turn off the mobile Internet on your smartphone so that the system is guaranteed to use the Wi-Fi channel.
It’s important to understand that channel bandwidth affects the bitrate of the video stream being transmitted. 4K video requires a much more stable channel than Full HD. If you plan to use Screen Mirroring often, you should consider upgrading your network equipment.
⚠️ Note: If your router supports customer isolation (AP Isolation, the broadcast won't work, and this is a function that blocks the communication between devices within the network, so you go to the router's settings and turn it off.
Using the built-in Cast feature on Android
The easiest and fastest way to display an image is to use the native Android feature, often called Translation, Smart View or Caste. On Xiaomi smartphones, this feature is usually built into the control center. Swipe from top to bottom to open the notification bar, and find an icon called Translation or a similar screen symbol.
Once activated, the phone will start searching for available devices on the local network. On the TV screen, a connection request may appear, which must be confirmed using the remote control. Modern Xiaomi TVs with Chromecast built-in support are determined by the system automatically, which simplifies the process to a couple of clicks.
The quality of the transmission depends on the load of the channel. If you notice a desynchronization of sound and image, try to lower the output resolution in the phone settings or bring the smartphone closer to the router, and close the background applications on the phone that may consume traffic.
☑️ Checking before connection
It is worth noting that when using this method, the phone and TV screen are completely synchronized, which means that any notifications coming to the smartphone will be visible on the big screen, so it is recommended to activate the "Do Not Disturb" mode before watching the film.
Broadcasting via Xiaomi Mi Remote and Mi TV
For Xiaomi and Redmi smartphone owners, the company has developed specialized software that is more deeply integrated into the ecosystem.The Mi Remote or Mi TV app (depending on the region and firmware version) allows you not only to control the TV as a remote control, but also to broadcast media files, which is especially convenient if the standard Miracast protocol is unstable.
Once you install the app and pair the devices, your TV will appear in the Devices section. Select it, and in the control menu, find the Translation button or image icon. Unlike system mirroring, you can often select a specific file from the gallery or video from the phone's memory without displaying the entire desktop.
| Parameter | System broadcasting | Mi TV appendix | Chromecasts inside apps |
|---|---|---|---|
| Type of transmission | Screen mirroring | Files and screen | Only the content of the application |
| Dependence on the phone screen | High (screen on fire) | Medium | Low (can be turned off) |
| Quality. | Depends on Wi-Fi. | Optimized. | Maximum. |
| Battery consumption | High-pitched | Medium. | Low. |
Using proprietary software offers the advantage of being able to control the mouse cursor from the phone, which turns the smartphone into a touchpad, which can be useful for navigating the TV menu if the remote is lost or faulty.
💡
If you're applying Mi TV Can't see the TV, try manually adding the device to the IP-address. IP-The address of the TV can be found in the settings of the network of the TV in the section "About the device".
Broadcast from YouTube, Netflix and other services
Special attention should be paid to the technology that allows you to stream content directly from aggregator applications such as YouTube, Netflix or IVi. In this case, the phone acts only as a remote control, and the video stream is downloaded by the TV directly from the Internet, which frees up the resources of the smartphone and provides the best picture quality.
To run, find the smartphone app's characteristic Chromecast icon. Click on it and select your Xiaomi TV from the list. The video will run on the TV, and the phone's display buttons will show playback and volume control.
The main advantage of this method is that you can use your phone for other tasks while you're watching, you can text, you can play games, you can play games without interrupting a movie on your TV, and the video quality is often higher, because it's not compressed by screencasting algorithms.
⚠️ Note: Service accounts (e.g., a Google YouTube account) on your phone and TV must be authorized to broadcast from apps, although this requirement is not always strictly enforced on the local network.
Third-party mirroring apps: AirScreen and others
If the built-in techniques don't work or your TV doesn't support a specific protocol (like AirPlay for Apple devices), third-party apps come to the rescue. One of the most popular Android TV solutions is AirScreen, which is installed directly on the TV through the Google Play Store on TV.
Once AirScreen is installed and launched on a TV, it emulates an AirPlay, Google Cast or Miracast receiver. On an iPhone, you just open Screen Replay in the control center, and on Android, you have a standard broadcast function. The app takes over the coding and streaming, often running more stable than the standard means.
There are also donor apps for the phone, such as Web Video Caster, which let you send a video file or a link to a web page directly to the TV, bypassing the need to mirror the entire screen, and it's a great way to watch videos from a site that doesn't have an official app on TV.
Why can a picture be laid down?
Wired connection via HDMI and adapters
For professional use, such as presentations or games where minimal latency is important, wireless methods may not be suitable, in which case the only right solution is cable connection, and since modern smartphones do not have an HDMI port, you will need a special adapter (USB-C to HDMI).
Connect the adapter to your smartphone, and it has an HDMI cable that goes to the TV. Switch the signal source on the TV (Input or button with a square and arrow) to the appropriate HDMI port. The image will appear automatically, because HDMI Alt Mode technology allows you to transmit a video signal through the charging port.
It is important to consider that not all smartphones support video output via USB-C. Xiaomi flagship models usually have this feature, but in budget segments, the port can only be limited to the USB 2.0 standard without a video output.
💡
The wired connection ensures no delays and maximum image quality, which is critical for dynamic games and text work.
Troubleshooting and troubleshooting
Even when set up correctly, there can be situations where devices can't see each other or the connection is constantly breaking. One common reason is to use a guest Wi-Fi network. Make sure both devices are connected to the main network, rather than guest access, where customer isolation is turned on by default.
If the broadcast is jerky, try turning off additional image processing on the TV, such as noise reduction or dynamic contrast, which can be loading the processor, and rebooting the router and cleaning the app cache that the broadcast is going through also helps.
- 🔌 Check that the cable HDMI (if used) is tightly inserted into the port and has no physical damage.
- 🛡️ Antivirus on your phone or firewall on your router can block local broadcast ports – try temporarily disabling them.
- 📺 Make sure the TV does not include the "Saving the Screen" mode, which can extinguish the display in the absence of active control.
In some cases, resetting network settings on a smartphone helps, and it won’t delete your data, but it will return the Wi-Fi and Bluetooth settings to factory values, which often solves problems with device detection protocols.
