Modern smartphones of the line Xiaomi Redmi have powerful screens, but to view high-quality content, there's often a need to display the image on a larger display. Cables are becoming a thing of the past, giving way to wireless technologies that allow for instant media streaming. Owners of Wi-Fi-based devices Android have several built-in tools to accomplish this task without purchasing additional equipment.
The main difficulty lies in the variety of data transfer protocols supported by different TV models. Some devices rely on the standard Miracast, others use technology Google Chromecast or proprietary solutions from the TV manufacturer. Understanding how each method works will help you avoid problems with image lag or missing sound.
In this article, we'll take a detailed look at all the available methods for syncing your gadget with your TV via your home network. You'll learn how to set up screencasting, which apps are best for video streaming, and how to troubleshoot common connection issues. The key is to ensure stable router operation, as transmission quality directly depends on the channel's bandwidth.
Preparing equipment and a Wi-Fi network
Before starting setup, make sure all system components are ready for operation. A fundamental requirement for any wireless data transfer is that all devices are on the same local network. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, make sure your phone also broadcasts signals on both 2.4 GHz and 5 GHz frequencies. Xiaomi, and the TV are connected to exactly one of them, although modern routers often combine them into a single network.
A stable connection is critical for streaming high-definition video. A weak signal can cause audio and video to become out of sync or artifacts to appear. Make sure the module is enabled on your smartphone. Wi-Fi and Bluetooth, as some device discovery protocols use Bluetooth for the initial handshake.
⚠️ Important: If your router has a "Guest Network" feature or AP client isolation, data transfer between devices will be impossible. Make sure your router settings allow data transfer within the local network.
It's also worth checking your operating system version. For modern codecs and screen mirroring protocols to work correctly, Redmi the current version must be installed MIUI or HyperOSSystem software updates often contain fixes for wireless module bugs.
☑️ Check before connection
Using the built-in "Broadcast" function
The fastest way to display an image from your phone screen on a TV is to use the native function of the Android system, which is in the shell MIUI called "Broadcast". This method is based on the protocol Miracast and allows you to duplicate the screen one to one, including the desktop, menu and running applications.
To activate the feature, open the Control Center or go to Connection Settings. Search for "Cast" in Settings or find the corresponding option under "Connection and Sharing." Once enabled, your phone will begin scanning for available displays within range.
When your TV's name appears in the list, tap it to pair it. A connection confirmation prompt may appear on the TV screen, which you'll need to confirm with your remote. From now on, any action on your smartphone will be reflected on the big screen with minimal delay.
It's worth noting that this method keeps the phone's screen on, which can lead to increased battery drain. If you're planning a long session, it's a good idea to connect your smartphone to a power source. Image quality depends on signal strength and airtime.
Streaming via Google Home and Chromecast
If your TV supports the technology Chromecast built-in or if you have a Chromecast connected to it, the best solution is to use the official app Google HomeThis method provides a more stable video stream, as the phone acts only as a remote control, and the video is downloaded directly from the internet by the TV.
To get started, install the application Google Home from the store Play Market, if it's not already installed. Open the app and find your TV in the list of devices. Click the device icon to open the control panel.
In the bottom menu, select the "Cast my screen" button. The system will warn you that your phone's audio and video will be broadcast to the TV. Confirm the action, and in a few seconds, your smartphone's desktop will appear on the TV.
The advantage of this method is that it puts less strain on the phone's processor and allows you to use the smartphone for other tasks without interrupting playback. However, it requires a stable internet connection on both devices, as traffic goes through Google's servers.
Xiaomi streaming apps and third-party solutions
Ecosystem Xiaomi offers its own solutions for interaction with a smart home, in particular an application Mi Home or Mi TVThese utilities not only allow you to mirror your screen, but also transfer specific files—photos and videos—from your gallery directly to your TV.
Additionally, there are universal third-party apps such as Web Video Caster or AllCastThey're especially useful if your phone's built-in features don't recognize your TV or aren't working properly. These programs often have their own codecs and can bypass the limitations of some file formats.
Using third-party software is usually simple: you open a video file or stream link within the app, select the target device, and start playback. The player interface allows you to control volume, rewind, and subtitles.
⚠️ Note: Some free versions of third-party apps may contain ads that will appear on your TV during streaming. For a more comfortable experience, consider purchasing the premium version.
Trust only verified developers with a good reputation in the app store.
Transfer photos and videos using the DLNA protocol
Protocol DLNA (Digital Living Network Alliance) is a standard for transmitting multimedia content over a home network. It's ideal for viewing photos and videos stored on your phone on a TV screen without having to mirror the entire smartphone screen.
Most modern TVs have a built-in media player with DLNA support. To start the process, simply open the "Media" or "Gallery" app on your TV and select the signal source—your smartphone. Xiaomi Redmi. In this case, a player application with DLNA support must be open on the phone, for example, VLC for Android or standard gallery.
In the appendix VLC Go to the "Network" tab and enable "Media sharing over LAN." After this, the TV will see your phone as a network storage device. You'll be able to open folders and files directly from your phone.
| Protocol | Transmission type | Phone addiction | Best use |
|---|---|---|---|
| Miracast | Screen mirroring | High (phone must be active) | Presentations, games, browser |
| Chromecast | Streaming | Medium (flow control) | YouTube, Netflix, online video |
| DLNA | File transfer | Low (cataloging only) | Photos, local video files |
| Mi Share | File sharing | Average | Quick file transfer |
Using DLNA saves battery life compared to full screen mirroring, as the video stream is decoded by the TV. However, this method is not suitable for displaying dynamic content, such as app interfaces or games.
Troubleshooting connection and latency issues
Despite the simplicity of setup, users may encounter issues where the phone doesn't detect the TV or the connection constantly drops. Most often, the cause lies in router settings or software conflicts. The first step should always be to reboot all devices: turn off and then on the router, TV, and smartphone.
If the problem persists, check whether your antivirus or firewall is blocking the local connection on your phone. Resetting your smartphone's network settings can sometimes help, but this will require you to re-enter your Wi-Fi password. Also, make sure your TV has the latest firmware version.
What should I do if there is sound but no picture?
This most often indicates a problem with the codec or resolution. Try changing the screen resolution in the streaming settings or using a different player that supports hardware acceleration.
Video lag often occurs when the Wi-Fi channel is overloaded by neighboring networks. In this case, switching the router to a less congested channel or using the 5 GHz band, which provides higher data transfer rates, can help.
Why doesn't my Xiaomi phone see the TV in the list of devices?
This may be due to the devices being connected to different router frequency bands (guest network), or the TV's broadcast reception function being disabled. Check your network privacy settings.
Is it possible to transmit an image without the Internet?
Yes, Miracast and DLNA technologies don't require internet access. Both devices only need to be connected to the same router, even if the router doesn't have access to an external network.
Does broadcasting affect internet speed?
Using Chromecast minimizes the load because the TV downloads the content itself. When mirroring your screen (Miracast), your phone creates a data stream, which can reduce speeds for other devices on the network.
How to improve image quality when mirroring your screen?
Make sure your phone's screen resolution matches your TV's resolution (e.g., 1920x1080). Also, disable power saving while broadcasting.
Does Wi-Fi Direct streaming work?
Yes, many TVs support Wi-Fi Direct, which allows you to connect your phone directly to the TV without using a router, creating a direct access point.
