How to send video from your phone to your Xiaomi TV via Wi-Fi

Modern users rarely limit themselves to watching content only on a smartphone screen. Often, you need to show friends vacation videos or run a movie on a big screen to get a more immersive experience. Xiaomi’s ecosystem offers many convenient ways to implement wireless image transfer using standard Wi-Fi protocol.

In this article, we will take a closer look at all the current broadcasting methods, from built-in system functions to third-party applications, and learn how to avoid delays, customize a high-quality picture, and solve typical connectivity problems without resorting to buying expensive adapters.

The key to successful data transfer is a stable connection. Before setting up, make sure that both devices are operating correctly and are within the router's signal-receiving zone, a basic requirement that negates all hardware capabilities.

Preparation of equipment and network

The first and most important condition is that you have a smartphone and a TV on the same local network, which means that both devices must be connected to the same router. If you have a dual-band router, you’d better use a 5GHz network, as it provides the higher bandwidth required for streaming video.

Check the operating system version on your Mi TV or Android TV Box. Most broadcast protocols require up-to-date software to work properly. Update often includes security fixes and improvements to the stability of the wireless module.

⚠️ Note: If your router supports Guest Network, do not connect your broadcasting devices to it, in which customer isolation may prevent the exchange of data between your phone and TV.

Also worth paying attention to energy saving: When you actively transmit video stream, the smartphone can significantly heat up and discharge quickly, it is recommended to keep the phone near the charger or use wireless charging while watching long movies.

Use of the built-in Screen Cast function

The easiest and fastest way to do this, which doesn't require additional software, is to use the system function Screen Cast, which is integrated into the control panel in the MIUI or HyperOS shell.

To start, open the notification curtain and find the Translation icon. Once activated, the phone will start searching for available devices on the network. The TV screen may have a request for permission to connect, which must be confirmed by the remote.

The advantage of this method is to transmit exactly what you see on the screen of the smartphone, including notifications and interface, but it is worth considering that this processor consumes the battery faster, and the quality of the image may depend on the power of the phone’s processor.

If standard search doesn't work, try rebooting the Wi-Fi module on both devices, sometimes by switching temporarily to the mobile network and back to Wi-Fi to reset your network settings.

Broadcasting via Mi Remote and Chromecast

Many modern Xiaomi and Mi Box TVs have built-in support for Google Chromecast technology, which allows you to stream content from compatible apps (YouTube, Netflix, VLC) directly without loading the phone’s processor with an interface display.

Unlike screen duplication, here the phone acts as a remote control: you select the video on the smartphone, click the broadcast icon (a rectangle with waves), and the video stream goes directly from the server to the TV over the Internet.

You can use Mi Remote to control the TV itself, which allows you to not only switch channels, but also initiate file transfers. The application interface often has a "Cast" or "Translate" button that opens access to the phone's media library.

What is the difference between Mirroring and Cast?
Mirroring copies the image from the phone's display in real time. This requires a constant transfer of a lot of data over Wi-Fi. The Cast only sends a link to the TV to the content that the TV downloads itself, which saves the phone's battery and often gives better picture quality.

It is important to note that Google Play services must be installed on the TV to run Chromecast, and in some regions or on Chinese TV versions, they may not be available, which will require additional installation. APK-file.

Video transmission via DLNA and third-party players

If you need to play a video file that has already been downloaded to the phone’s memory, it is most convenient to use the DLNA protocol. To do this, a player with support for this technology is installed on the smartphone, for example, VLC for Android or XPlayer.

The algorithm of actions is simple: open the video in the player, select the option "Play on the device" (Cast) and choose your Mi. TV. The TV will receive a stream of data and decode it on its own, which is especially important for heavy duty. 4K-file.

Using third-party players often gives more customization, such as a choice of audio tracks or subtitles, which may not be supported by a standard TV player.

Some file managers, such as ES Explorer or MIUI-built file manager, also have DLNA built-in function. You can simply clip a video file, select Send, and find your TV in the list.

Setting up DLNA-TV-server

In some cases, especially when working with Chinese firmware versions, the standard DLNA receiver can be hidden or disabled, in which case installing a server application on the TV, such as Serveo or using the built-in Media Player, helps.

Once the server is uploaded to the TV, it becomes visible to other devices on the network, which allows you not only to stream the video, but also to access folders with photos and music, turning the TV into a multimedia center.

For advanced users, static settings are available IP-This ensures that the path to the device does not change after the network reboot, which is convenient for constant settings.

Solving Connection and Buffering Problems

The most common problem with wireless transmission is the desynchronization of sound and image or constant buffering, which almost always indicates low Wi-Fi speeds or interference in the air.

Try to move the router closer to the TV or, conversely, remove it from the microwave ovens and Bluetooth headsets, which can cause interference in the 2.4 GHz band. Switching to 5 GHz often solves the problem dramatically.

⚠️ Attention: If the video twitches, try to reduce the quality of playback in the source application. 4K HDR Poor Wi-Fi content may not be possible without staff loss.

Also check if the phone is running heavy downloads or app updates, they can strangle the channel needed for a stable video stream, close the unnecessary browser tabs and background processes.

Use of the USB-storage as an alternative

If the wireless network is overloaded or unstable, there is always a time-tested method. USB-Xiaomi TVs are great at reading file systems FAT32 and NTFS.

Just copy the video file from your phone to your flash drive (using OTG-cable if the phone does not have a memory card slot) and insert the drive into USB-The TV port guarantees maximum quality without compression and delays.

Use the exFAT file system for flash drives larger than 32GB if your TV supports it, allowing you to record files larger than 4GB, which is critical for high-resolution movies.

This method is also useful if you want to transfer a file that is protected. DRM-It is protected and not broadcast over Wi-Fi (black screen when trying Cast.

FAQ: Frequently Asked Questions

Why does Xiaomi TV not see the phone when searching?
Most likely, the devices are connected to different networks (for example, one to 2.4 GHz, another to 5 GHz, and the router isolates them (AP Isolation).
Can I stream the iPhone screen on Xiaomi TV?
Yes, but to do this, you need to install an app that supports AirPlay (for example, "AirScreen" from the Google Play Store on your TV). Xiaomi's standard protocol does not support AirPlay out of the box.
The broadcast is delayed, can you play games on the TV through the phone?
For dynamic games, the latency of wireless broadcasting will be too great, a method that is suitable for video, photo and turn-based games, but not for shooters or racing.
How to improve the quality of the image during broadcasting?
Use a router that supports Wi-Fi 5 (AC) or Wi-Fi 6 (AX). Make sure your phone and TV are in line of sight of the router. Turn off the VPN on your phone, as it can route traffic across other countries, increasing ping.

πŸ’‘

The stability of wireless broadcasting is 90% dependent on the quality of your Wi-Fi router and the absence of interference in the air, not just on the characteristics of the TV.
