How to connect Xiaomi Redmi to a TV via WiFi: an expert guide

Modern Xiaomi and Redmi smartphones have powerful displays, but to view content in high quality, you often want to display an image on a large screen. Wi-Fi is the most convenient way to do this, eliminating the need to search for cables and adapters. Wireless data technology allows you to broadcast video, photos and even the entire screen of a smartphone to a TV in seconds.

The connection process can vary depending on your TV model and the version of the MIUI or HyperOS operating system. Some users have difficulty finding the right menu, while others can’t find the device in the list of available. In this article, we will discuss in detail all current connection methods, including built-in functions and third-party solutions.

It's important to understand that for successful synchronization, both devices must be on the same local network. The router acts as an intermediary, transmitting a video stream with minimal latency. If your router supports dual-band mode, it is recommended to use a 5 GHz network to ensure a stable picture without jerks.

Wireless technologies: Miracast, DLNA and Chromecast

Before you start setting up, you need to understand the terms, because different apps and TVs use different protocols. Miracast is a wireless media standard that allows you to duplicate a smartphone screen on a TV in real time. This technology is built into most TVs with Smart TV function and does not require an Internet connection, working directly through WiFi Direct.

By contrast, DLNA is primarily designed to transfer media content (photos, videos, music) from a device’s memory, not to broadcast the system interface. Xiaomi actively uses this protocol in its standard video player. You just select a file, press the broadcast button and enjoy the content on the big screen while the phone can be used for other tasks.

The third popular standard is Google Chromecast built-in, which is integrated into many modern TVs and allows you to stream content from compatible applications such as YouTube or Netflix, in which case the phone acts as a remote control, and the video stream goes directly from the server to the TV, which saves battery power of the smartphone.

• 📺 Miracast – full screen duplication, ideal for presentations and games.
• 🎬 DLNA — streaming files from memory, saves phone resources.
• 🌐 Chromecast – Content management from the cloud, high quality images.

⚠️ Warning: Miracast protocol can put a noticeable load on the smartphone processor and quickly discharge the battery during prolonged use.

Device preparation and network setup

The foundation of successful connectivity is the right LAN organization: Make sure your Xiaomi Redmi and TV are connected to the same router. Often users face the problem when the phone is running over a 4G mobile and the TV is connected to a home WiFi, making them "invisible" to each other.

Check router settings: AP Isolation must be turned off. If it is activated, WiFi-connected devices will not be able to communicate with each other even when on the same network. Older TV models may also need to enable DLNA or Screen Mirroring support in the settings of the TV itself via the remote.

Update your smartphone software to the latest available version. From Settings menu → About your phone, check for system updates. Xiaomi developers regularly release patches that improve wireless connectivity and compatibility with different TV models.

Broadcasting the screen through the built-in “Translation” function

The fastest way to display an image is to use a system function called Translation or Cast in the MIUI shell, which implements the Miracast protocol and works with most modern Smart TVs (Samsung, LG, Sony, Philips, etc.).

To run, drop the swipe notification curtain from top to bottom and find the Broadcast icon. If it's not available in quick access, tap on a pencil or three menu editing dots and drag the icon to the active screen. Alternative path: go to Settings → Connection and Sharing → Broadcast.

Once you turn on the feature, the phone will start looking for available devices. When your TV appears on the list, click on it. You may see a request for permission to connect on the TV screen — confirm it with the remote control. The image from the phone will instantly appear on the big screen.

In some versions of Redmi firmware, this feature may be called the Wireless Monitor, and the principle of operation remains the same: search for a device on the local network and establish a secure connection to transmit a video stream.

⚠️ Note: When using the “Translation” function, the smartphone screen will burn constantly, which leads to increased energy consumption.

Using the Mi Remote application for management

Xiaomi and Redmi smartphone owners have a unique advantage: an integrated IR port (in most models) and a pre-installed Mi Remote app, which is primarily designed to emulate the remote, but in some scenarios, it helps to interact with media content.

If your TV doesn't support Miracast directly, but it's a Smart TV, the app can find it on the local network. Add the device by selecting the manufacturer from the list. Once paired, you can use the phone as a touchpad or keyboard to type in text, which is especially handy when searching for YouTube videos through the TV.

To transfer photos and videos from the gallery, open the desired file, click the Share button or the broadcast icon (rectangle with WiFi waves) and select your TV from the list of DLNA devices. This does not duplicate the screen, but sends the file to play.

Third-party applications for complex cases

If Xiaomi’s built-in tools don’t see the TV or are not running smoothly, third-party solutions from Google Play Market come to the rescue. The TV Cast or Web Video Caster app often works where system tools are shedding, especially with older TVs.

Google Home is the official Chromecast tool. Install it and it will automatically find all compatible devices on the network. The Translate Screen feature in the app menu allows you to duplicate a Redmi display on any Chromecast-enabled TV.

For TVs without Smart TV You can use special receivers (dongles) that connect to the HDMI-They're building their own WiFi network, which the phone connects to to transmit the image, and then the router doesn't need to be used.

Solving Connection Problems and Errors

One of the most common problems is when the phone sees the network but doesn't see the TV. Make sure the router doesn't have a guest network for one of the devices. The guest network isolates the devices from each other for security reasons, blocking the transmission of media streams.

If the connection resets after a few minutes, check Xiaomi's power saving settings.The system can force the broadcast process to save charge. Add the Translation or Mi Video app to the exception list or set No Limits mode in the battery settings.

If you have problems with image quality (artifacts, pixelation), try to bring your phone closer to the router. WiFi signal can weaken due to walls or microwave oven operation. Switching to 5 GHz frequency often solves the problem of interference.

💡

If the TV is not on the list, try to temporarily turn off the TV. VPN Virtual private networks often change the region or IP-Address that hides local devices from the detection system.

Frequently Asked Questions (FAQ)

💡

The stability of the connection depends on the quality of the WiFi signal of the router and the absence of software locks in antivirus or network privacy settings.
