Modern smartphones Xiaomi and Redmi have powerful multimedia capabilities that you often want to use on the big screen. Connecting your phone to your TV via wireless Wi-Fi is the most convenient way to show photos, gallery videos, or even run a game full-screen without unnecessary wires. HDMI-cables, Miracast wireless technology and Mi Home proprietary solutions provide high data transfer speeds and minimal image latency.
The process of synchronizing devices takes only a few minutes if both gadgets are on the same local network. users of the Xiaomi ecosystem have unique control functions that turn a smartphone into a universal remote. It is important to understand that the quality of the broadcast depends on the stability of the router signal and the software version of both devices. In this article, we will discuss in detail all available pairing methods.
Before you start setting up, make sure your Smart TV supports wireless display technology. Most current models from Samsung, LG, Sony and Android TV have built-in modules to receive the signal. If you have an older model, you may need to use additional adapters, such as Chromecast or Miracast whistles, plugged into the HDMI port.
Basic requirements and equipment preparation
A successful connection requires a set of preconditions that will lead to device search errors, the first and most important requirement being that the smartphone and TV are on the same subnet, which means that both devices must be connected to the same Wi-Fi router.
Often users face the problem when the phone “sees” the 5 GHz network and the TV only works in the 2.4 GHz band. In modern routers, these ranges are often combined into one network with the same name, but sometimes they are separated. For stable high-resolution video transmission (4K HDR), it is highly recommended to use the 5 GHz band, as it provides bandwidth up to 1300 Mbit / s.
It’s also worth checking for updates to your Xiaomi’s Translation or Wireless Display system app. Depending on the version of the MIUI or HyperOS shell, the feature name may vary. Make sure your TV has a Screen Mirroring, Anyview Cast or similar standby mode.
⚠️ Note: If your router is set up with customer isolation (AP Isolation, devices won't see each other even on the same network, a feature often included in guest networks for security.
Check the battery of your smartphone. Active video streaming consumes a lot of energy, and the device may shut down while watching a movie. It is recommended to keep the phone connected to the charger or have a charge above 50%.
Use of the built-in "Translation" (Wireless Display) function
The easiest and fastest way to display an image is to use a native Android tool, which is called Translation in Xiaomi’s shell. This method does not require installing third-party applications and works at the operating system level, providing minimal latency.
To activate the function, swipe the notification curtain (“”) from top to bottom. Find an icon called “Translation” (or “Cast”, “Wireless Monitor”). If the icon is not in quick access, click on the menu edit button (usually a pencil or three dots) and add it to the panel.
After turning on, you will automatically search for available devices within the range of Wi-Fi. A request for permission to connect may appear on the TV screen - confirm it using the remote control. Response time is usually from 2 to 5 seconds.
If the search is not working, try restarting the Wi-Fi module on your phone or restarting the TV. Sometimes it helps to force the Translation process to end in Task Manager and restart it. In the feature settings, you can change the image quality or resolution if you see the sound and video being out of sync.
☑️ Checklist for quick setup
Mi Home app: management and duplication
Xiaomi’s smart home ecosystem offers a more advanced tool, the Mi Home app, which allows you to not just duplicate the screen, but also use your smartphone as a full-fledged remote control with advanced features, especially for Mi TV and Redmi TV owners.
To get started, download the app from Google Play or Mi GetApps and log in to your Mi Account. Add your TV to the device list if it doesn't already appear in the main menu. To do this, click "+" in the upper right corner and select the TV from the list of gadgets found.
In the TV control interface, find the Translation button or the arrow screen icon. The system will suggest you to choose the mode: duplication of the entire screen or broadcasting a specific media file. The first option is suitable for games and the browser, the second one is for saving resources when watching videos from the gallery.
| Function | Description | Requirements |
|---|---|---|
| Screen duplication | Full copy of smartphone image | Wi-Fi Direct |
| Video broadcasting | Just content, phone like remote | DLNA / Chromecast |
| DU remote | Volume control, menu, voice control | Bluetooth / Wi-Fi |
| File transfer | Sending photos and APK to TV | Mi Drop / ShareMe |
Using the Mi Home app gives you the benefit of voice control and the ability to create scripts, for example, when you run a movie on your phone, the TV can automatically turn on and go into the desired mode, which creates the effect of a real smart home.
The Secret Mi Home Function
Broadcasting via Google Home and Chromecast
Many modern TVs, even those not part of the Xiaomi ecosystem, support Chromecast built-in technology, which allows you to stream content directly from apps like YouTube, Netflix or VLC using Google’s infrastructure.
To work with this method, the Google Home app must be installed on your smartphone. Once launched, the app will scan the network and find all compatible devices. Click on your TV icon and select the "Cast screen" option.
The main difference from Xiaomi’s standard streaming is that Google Home often provides more stable connectivity and better optimization for Google services.However, the latency can be slightly higher, making this method less suitable for dynamic gaming.
If the TV doesn’t have a built-in Chromecast, you can use an external Chromecast or Android TV Box. In this case, the phone connects to the console in the same way as a regular TV, but the functionality can be extended by the ability to install apps directly on the console.
⚠️ Attention: When streaming through Google Home, the sound may be delayed. For movies, this is offset by buffering, but in games, lagas can be noticeable.
Third-party applications for complex cases
Sometimes, regular tools don't work properly because of protocol incompatibility or router-specific settings, and in these cases, third-party solutions available in the Play Market store come to the rescue, often with more flexible codec and buffering settings.
One of the most popular solutions is the AirScreen application (installed on the TV) in conjunction with any other software. DLNA-Another option is to use LocalCast or BubbleUPnP on a smartphone, which can throw video files to almost any Smart. TV.
For advanced users who want to stream a computer or phone screen with minimal delays, Scrcpy bundle (via ADB) or ApowerMirror application will be suitable. These tools require more complex initial configuration, including debugging over USB, but give maximum control over the process.
💡
If standard broadcasting is slowing down, try to lower bitrate or output resolution in third-party apps. This is the quality of the picture, but it will make the movement smoother.
When using third-party software, pay attention to the permissions you give the application. To work properly, they often need access to storage, microphone (to transmit sound), and local network. Without these permissions, functionality will be limited.
Diagnostics and troubleshooting
Even with the right setup, you can have a crash: the image twitches, the sound disappears, or the phone doesn't see the TV at all. The first step in diagnostics should always be to restart the router. Often the problem is cache overflow. DHCP-server-side IP-address.
If audio and video are desynchronized, try changing the frame rate settings in the stream menu. Also check if background downloads are running on other devices on the network that can strangle the Wi-Fi channel. 4K video stream requires a stable speed of at least 25 Mbps.
In some cases, an antivirus or firewall on a router will block the ports required for the Miracast protocol. Try temporarily disabling packet filtering or creating a guest network with no restrictions to test the hypothesis.
💡
90% of connection problems are solved by simply restarting the router and checking that the phone and TV are in the same frequency band (2.4 or 5 GHz).
If nothing helps, reset the network settings on your phone (Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth).This will delete all saved passwords, but often resolves software glitches of the Android network stack.
