Today’s Xiaomi, Redmi and POCO smartphones have powerful multimedia capabilities that allow you to display images on a large screen without using wires. Wi-Fi wireless data has become the standard for watching photos, videos and games on TV. Users often look for ways to quickly and without delay broadcast content using built-in MIUI or HyperOS features.
The setup process can vary depending on your TV model and the version of your smartphone operating system. There are various transmission protocols such as Miracast, DLNA and Google Cast, each of which has its own features. In this article, we will discuss in detail all the available connection methods so that you can choose the most suitable equipment for your configuration.
It is critical to successfully synchronize devices, and it is essential that both devices are on the same local area network, a basic requirement for most wireless data technologies. If a router is sending out signals at 2.4 GHz and 5 GHz, make sure that the phone and TV are connected to one of them, although modern routers often combine them into a single network.
Compatibility check and equipment preparation
Before you start setting up, make sure your hardware supports the required wireless standards. Most modern Smart TVs from Samsung, LG, Sony and of course Xiaomi Mi TV have built-in Wi-Fi Direct modules. Redmi Note smartphones and Mi flagship models also come with all the hardware they need.
Make sure that both devices are enabled with a wireless module. Sometimes geolocation is required to be activated for stable operation, since in Android this resolution is often used to find available devices on the network. Check if the phone is power-saving mode, which can limit the background operation of network services.
⚠️ Note: If your TV is not smart TV, Wireless broadcasting is not possible without the use of an external console, for example, Chromecast or Apple TV.
To ensure smooth video stream without jerking and buffering, it is recommended to use a high-bandwidth network. the Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) standard will provide the best performance when transmitting video in high resolution 4K.
Use of the built-in Translation function in MIUI
The easiest way to stream from your phone to your TV via WiFi Xiaomi is to use a system utility, which is often called Translation or Wireless Monitor on the MIUI and HyperOS shells, and is based on the Miracast protocol that most TVs support.
To activate, open the curtain control panel and find the Translation icon. If it's not on the home page, click three dots or an edit icon to add the widget to the active menu, and then start searching for available devices within network range.
When the name of your TV appears on the screen, click on it to pair, the TV screen may have a request for confirmation of connection, which must be coordinated by the remote, from which point the image from the phone will be duplicated on the large screen in real time.
☑️ Preparation for broadcast
It is worth noting that using this method, the phone screen does not go out, which can lead to increased battery consumption. Some models allow you to lock the screen of the smartphone while continuing to broadcast, but this depends on the specific version of the firmware and the model of the TV.
💡
To reduce latency when gaming, close all background apps that consume traffic, such as browser downloads or updates to the Play Market.
Broadcasting via Mi Home and Mi Remote
Xiaomi’s ecosystem offers unique opportunities for Mi TV and Mi Box owners. The official Mi Home app (or Xiaomi Home) not only allows you to manage your smart home, but also to cast multimedia content, which is especially convenient if the standard Translation feature is unstable.
Once you install the app and add the TV to your device list, go to your TV card. The control menu often has a "Translate to TV" or similar button, which uses proprietary protocols optimized specifically for the brand's hardware.
| Method | Protocol | Delay. | Quality. |
|---|---|---|---|
| Systemic “Translation” | Miracast | Low. | High. |
| Google Home | Chromecast | Medium | Maximum. |
| Mi Home / TV Assistant | DLNA / Proprietary | Low. | High. |
| Third-party annexes | Different | Depends on the software. | Average. |
The advantage of using proprietary apps is deep integration with the system: you can use the phone as a remote, have access to the file system, and run apps directly on the TV using the smartphone as a controller.
⚠️ Note: When using the Mi Home app, make sure it has permissions to access the LAN, otherwise it won’t be able to detect the TV.
Google Chromecast technology built-in
Many modern TVs, including Xiaomi models with Android TV, have built-in support for Google Cast technology.This allows you to stream content from source apps such as YouTube, Netflix, Google Photos or the Chrome browser directly to the TV, bypassing the smartphone screen.
Unlike mirror display, the phone is only a remote control, and the video file is downloaded directly from the Internet by the TV, saving the phone's battery and unloading the Wi-Fi channel. To run, look for the source app icon with the waves in the corner.
Click on the icon and select your TV from the list. If the devices are on the same network, the connection will be established automatically. You can turn off the app or use the phone for other tasks while the video is played on the large screen.
What if the Cast icon doesn’t appear?
It's important to understand the difference between mirror reflection and Cast broadcasting: in the first case, the phone encodes the video stream of its screen and sends it, in the second case, the phone only tells the TV to play the content on the link, the second option provides better quality and stability.
Video and photo streaming via DLNA
DLNA remains a popular way to transfer media content stored in a smartphone’s memory to a TV, and unlike Miracast, it does not broadcast the entire screen, but allows you to select specific gallery or video player files for playback on TV.
It doesn’t always require third-party apps. Xiaomi’s standard gallery or Mi Video player often have a built-in Send to Device or DLNA icon. Open a photo or video, click a (share) button or three-dot menu, and select your TV.
The TV should support Media Renderer, which is the standard for all Smart TVs. Once the file is selected, buffering will begin and the content will appear on the screen, ideal for watching family albums or movies downloaded to the device's memory.
The main advantage of DLNA is the ability to control playback (pause, rewind) from your smartphone without getting out of the couch, but file formatting must be supported by the TV, otherwise you will see a playback error message.
💡
DLNA is ideal for viewing local files, as it does not load the phone’s processor and does not require a constant screen on.
Solving Connection Problems
Despite the simplicity of the technology, users may have difficulty seeing the TV or the connection is constantly broken, most often the problem is in the settings of the router. Make sure that the router does not include client isolation (AP Isolation), which prevents devices on the same network from communicating.
Another reason could be outdated software. Check for updates to the phone system in Settings → About the phone and the TV in its system menu. Different protocol versions may conflict with each other.
If the connection is unstable, try rebooting the router. Long-term networking can lead to buffer overflows or routing table errors, and it is also worth checking whether the Wi-Fi channel is overloaded with neighboring networks, which is especially true in apartment buildings.
⚠️ Warning: Antivirus apps or firewalls on your phone can block outbound connections for broadcast. Try temporarily disabling protection to check.
In some cases, resetting network settings on a smartphone helps, which will remove stored Wi-Fi passwords and Bluetooth settings, but often solves problems with software failures of the operating system network stack.
