How to connect your smartphone to a Xiaomi Mi TV via Wi-Fi

Xiaomi’s modern smart TVs offer users a wide range of multimedia experiences, turning a video viewing experience into a full-fledged digital experience. Connecting a mobile device to a large screen via a wireless Wi-Fi network is the most convenient and aesthetic way to rid space of unnecessary wires and cables, a method that is especially relevant when you need to show photos to friends, launch a video file from a cloud storage or even play a mobile game on a huge diagonal.

The process of synchronizing the gadget with Xiaomi Mi TV is based on standard data protocols such as Miracast and DLNA, which are built directly into the Android TV operating system. You do not need to purchase expensive adapters or complex adapters if both devices are on the same local network. However, despite the apparent simplicity, there are nuances of setting up the router and the devices themselves, ignoring which can lead to the inability to detect the display or unstable connection.

In this article, we will take a look at all the wireless connectivity available, from native system functions to specialized software. You will learn how to configure screen broadcasts for different operating systems, which applications are best for streaming content and how to fix common connection errors. It is critical that both devices are on the same Wi-Fi subnet (2.4 GHz or 5 GHz frequency should match), otherwise the TV may simply not see the phone.

Equipment preparation and network settings

The first and most important step is to organize your local network correctly, as it is the quality of the Wi-Fi signal that determines the stability of the video stream. Make sure your router supports IEEE 802.11n standards or later, as older versions may not be able to handle real-time video transmission. If your router is dual-band, it is strongly recommended to connect both the TV and smartphone to the same frequency, preferably 5 GHz, for maximum channel bandwidth.

You also need to check the relevance of the software on both devices, as manufacturers regularly release patches that improve the compatibility of the Cast and AirPlay protocols. On Xiaomi TV, this can be done by going to the settings menu and selecting the system update point, and on a smartphone, the check is carried out through Google Play or the App Store. Sometimes the problem of lack of visibility is solved by a banal reboot of the router, which could accumulate errors in the routing table over a long period of time.

If you have AP Isolation enabled on your router, Wi-Fi-connected devices won’t see each other, making it impossible to stream, and on most home networks, this feature is disabled by default, but on corporate or guest networks, it can be active to improve security.

Use of the built-in Chromecast feature

The Android TV operating system, which is installed on Xiaomi TVs, has built-in support for Google Chromecast technology.This allows you to stream content from supported apps like YouTube, Netflix or Google Photos directly to the TV screen without having to duplicate the entire screen of your smartphone. To get started, you need to open the app on your phone, click on the broadcast icon (a rectangle with waves) and select your Xiaomi Mi TV from the list of available devices.

The advantage of this method is that it can use the smartphone for other tasks while the video is played on the TV, since the TV itself takes over the flow control. The picture quality is usually higher than with simple duplicate screens, since the video stream is transmitted directly from the server to the TV, bypassing the phone's processor.

⚠️ Note: If the broadcast icon doesn’t appear in the app, check that apps on your phone and TV use the same Google account, or make sure the router’s settings don’t block the ports required for mDNS to work.

In some cases, you may need to manually activate the Cast reception function on the TV itself. To do this, the Xiaomi remote often has a separate button or key combination that triggers the signal source menu, where you choose the Wireless Display or Cast. After that, the TV will go into the connection standby mode, and its name will be visible for scanning by the mobile device.

💡

For better picture quality when using Chromecast, close the background apps on your smartphone to free up processor resources and RAM.

Screenplay via Miracast and Wireless Display

If your goal is to mirror the screen of your smartphone completely, for example, to show a presentation or a game that does not have built-in Chromecast support, you will need Miracast technology. Owners of Android devices need to go to the system settings, find the Connections or Translation section (the name may vary depending on the model and version of the shell) and start searching for displays. Xiaomi TV should appear on the list as an affordable Wireless Display device.

For iPhone and iPad users, the situation is a little different, as Apple uses its proprietary AirPlay protocol. Fortunately, many modern Xiaomi Mi TV models support AirPlay 2 natively or through the installation of the corresponding application from the Google Play Store. Once AirPlay is activated in the TV settings, you will be able to display the iOS device screen through the standard "Screen Replay" item in the control center.

It's important to understand the difference between transmitting a media file and duplicating a screen. When using Miracast, the phone encodes the video stream in real time and sends it to the TV, which puts a strain on the battery and the processor. If you notice twitching or desynchronizing the sound, try lowering the output resolution in your phone's settings or getting closer to the router.

Application Mi Remote and Mi Home

Xiaomi’s ecosystem offers its own tools for managing equipment, among which the Mi Home and Mi Remote app stand out. Although the main function of Mi Remote is to control the TV using a smartphone as a remote, in some versions and regions the functionality allows you to transfer media content.

The Mi Home app serves as a central hub for all smart devices, and adding a TV to that system opens up additional automation scenarios, such as setting up a scenario where when you run a particular movie on your phone, the TV automatically turns on and switches to the desired signal source, which requires a deeper setup, but greatly improves user experience.

To transfer photos and videos through native applications, Xiaomi often just open the gallery, select the desired files, click the “Share” button and select your TV from the list of devices. This method uses the DLNA protocol, which is great for viewing pre-loaded files, but is not suitable for streaming online video from browsers or games.

⚠️ Note: When using third-party apps from Xiaomi, make sure you download them from the official Google Play store or App Store to avoid malware that could steal your local network data.

Third-party broadcast applications

If standard tools don’t meet your requirements or are not working smoothly, Google Play apps like Cast to TV, AllCast or LocalCast come to the rescue, and they offer advanced functionality that allows you to stream not only videos and photos, but also browser content, documents and even application screens that block standard broadcasting, often with their own codecs, which improves compatibility with different file formats.

One popular utility is Screen Mirroring, which creates a virtual bridge between your phone and your TV. Once you install the app on your smartphone and, in some cases, the receiver on your TV (via the APK file), you can access advanced bitrate and resolution settings, which is especially useful for older router owners, where you need to manually reduce the flow quality to eliminate lags.

It’s also worth mentioning browsers with Cast, like Google Chrome. When you open a tab with an online movie theater or website, you can click on a three-dot menu and select Translate, then select Translate tab or Translate screen. This is a versatile way that works on almost any Android smartphone without installing additional software other than the browser itself.

Solving problems and eliminating mistakes

Despite the simplicity of the technology, users often face problems when the TV can’t see the phone or the connection is constantly broken. One of the most common reasons is the use of different Wi-Fi frequencies: if the phone is connected to 5 GHz and the TV is to 2.4 GHz, they can be on different subnets, especially on complex routers, in which case you need to switch one of the devices or merge the networks into one SSID.

Another common problem is antivirus software or firewalls on your smartphone that block incoming and outgoing connections on your local network.Try temporarily disabling protection or adding a TV to your trusted device list. Also helps reset network settings on the phone, which clears the cache DNS and ask again IP-router.

• 📶 Weak signal: Make sure that the Wi-Fi signal strength on both devices is at least 2-3 Divide; use a Wi-Fi repeater if necessary.
• 🔄 Outdated Software: Check for updates for YouTube or Android TV TV settings.
• 🔌 Reboot: Completely de-energize the TV (pull out of the socket) for 1 minute to reset Wi-Fi module errors.

If nothing helps, you can try static. IP-Write for your TV and smartphone constants IP-Addresses in router settings to eliminate addressing conflicts that sometimes occur with a large number of connected devices in a smart home.

💡

90% of connection problems are solved by restarting the router and checking that both devices are on the same frequency network (2.4 or 5 GHz).
