Modern smartphones such as Xiaomi Redmi 8, have become powerful multimedia centers that we carry in our pockets. However, the small screen of a mobile device is often insufficient for comfortable viewing of movies, photo sessions, or games. Wireless data transmission technology allows you to stream images and sound to a large TV screen without the need for unnecessary cables.
There are several proven methods for establishing a connection between a gadget and a TV, and the choice of a specific method depends on the protocols your TV supports. Android device owners can use built-in system functions, third-party apps, or proprietary utilities from the manufacturer. The only important thing is that both devices are on the same local network.
In this article, we will examine in detail all available connection options. Xiaomi Redmi 8 We'll explain the difference between Miracast and Chromecast technologies, and address common syncing issues. You'll learn how to quickly stream content and enjoy high-definition multimedia.
Preparing equipment and setting up the network
Before you begin setup, make sure your equipment is ready for use. A stable connection is essential for wireless data transfer. Make sure your router is working properly and transmits a signal at a frequency of 2.4 GHz or 5 GHz.
Both devices—the smartphone and the TV—must be connected to the same Wi-Fi network. If you have a dual-band router, it's better to use the 5 GHz network for streaming high-definition video, as it provides higher throughput.

- 📺 Make sure your Smart TV is turned on and connected to the internet.
- 🔄 Update your TV firmware to the latest version.
- 🔋 Charge your smartphone to at least 40% to avoid power outages.
If you're using a guest Wi-Fi network or a network with client isolation, devices may not be able to see each other. In this case, you'll need to access your router settings and disable isolation or switch to your main home network.
⚠️ Please note: When using public Wi-Fi networks in cafes or hotels, screen sharing may not be possible due to security restrictions set by the network administrator.
Using the built-in "Broadcast" function (Miracast)
The easiest way, which doesn't require installing any additional software, is to use Miracast technology. In the MIUI interface installed on the Redmi 8, this feature is often called "Cast" or "Wireless Display." It allows you to mirror your smartphone's screen to your TV in real time.
To activate the feature, pull down the notification shade and find the "Cast" icon. If it's not on the main widget screen, tap the edit button (usually three dots or a pencil) and add a shortcut. On your TV, you may also need to launch the Screen Mirroring app or select the appropriate input source.
Once the search is enabled, your phone will begin scanning for available devices. Once your TV's name appears in the list, tap it to pair it. Screenshot Xiaomi Redmi 8 will instantly appear on the large display.
It's worth noting that when using Miracast, your smartphone's screen stays on, and all notifications received on your phone will be visible on your TV. This can be inconvenient when watching movies if you receive a private message.
Google Chromecast technology for streaming
A more advanced method is to use a protocol Chromecast built-in (formerly Google Cast). Unlike Miracast, which simply mirrors your screen, Chromecast allows you to stream content directly from a server to your TV, using your phone as a remote control.
Most modern Smart TVs from Samsung, LG, Sony, and Philips already have built-in support for this technology. To use it, you'll need an app. Google Home, which can be downloaded from the Play Market, although it is often pre-installed on certified Android smartphones.
Launch the Google Home app and find your TV in the list of devices. Tap the "Cast my screen" button. This will provide a more stable picture and reduce the strain on your smartphone's battery, as the TV buffers the video itself.
A huge advantage of Chromecast is the ability to control playback from different apps. You can launch a YouTube video, press the cast button within the app, and it will play on your TV, leaving your phone free for other tasks.
Branded apps and Mi Drop
Xiaomi offers its own solutions for interacting with the smart home ecosystem. The application MI Remote (The remote control) allows you to not only control the TV, but also, in some Xiaomi/Mi TV models, transfer files and media.
Also worth mentioning is the feature Mi Drop (now known as ShareMe), which allows for quick file transfers over Wi-Fi Direct. While it's not a live screencast, you can still cast photos or videos to your TV (if it supports SMB file transfer or has the Mi Remote/Mi TV app) and start playing them.
For Xiaomi TV users, this method is native and the fastest. Select "Mi Remote" or "Mi Drop" in the TV menu, then launch the corresponding app on your phone and select the file to send.
⚠️ Note: The MI Remote app interface may vary depending on the MIUI version and region. In some versions, the screen sharing feature is located in a separate menu.
If you have a TV from another brand but want to take advantage of the ecosystem, try installing an app on your TV that supports the DLNA protocol and streaming content through your smartphone's file manager.
Streaming via third-party apps (DLNA and AirPlay)
If built-in methods don't work or your TV is an older Smart TV model, third-party apps can help. The leaders in this niche are Web Video Caster, BubbleUPnP And TV Cast.
These programs use the protocol DLNA To stream media files, you install the app on your Redmi 8, select a file (video, photo, music), and specify the target device. The TV receives the data stream and plays it automatically.
For users who want to mirror their iPhone screen to an Android TV or vice versa, there are AirPlay emulator apps. These create a virtual receiver on the TV that the phone perceives as an Apple device.
| Application | Connection type | Format support | Presence of advertising |
|---|---|---|---|
| Web Video Caster | DLNA / Chromecast | MP4, MKV, AVI, HLS | There is (in) |
| BubbleUPnP | DLNA / Chromecast | All popular | No (in the basic version) |
| TV Cast | Browser casting | Web video | Eat |
| LocalCast | DLNA / SMB | Video, Photo, Audio | Eat |
Using third-party software often allows you to stream content from sources that don't have a built-in "Cast" button, such as videos from private websites or files from cloud storage.
Why might DLNA not work?
The DLNA protocol is sensitive to codecs. If the TV doesn't support the video format (for example, HEVC on older models), the file won't play, even if the stream is successful. In this case, on-the-fly transcoding via a PC server or file conversion will help.
Troubleshooting and connection diagnostics
Despite the simplicity of the technology, users often encounter problems: the phone doesn't detect the TV, the connection drops, or the audio and video become out of sync. First, always check that the devices are on the same subnet.
A common cause of problems is an antivirus or firewall on the router, which blocks the ports required for discovery protocols. Issues can also arise due to an outdated DNS cache on the smartphone.
☑️ Connection diagnostics
If the image is choppy or of poor quality, try lowering the output resolution in the streaming settings or moving your smartphone closer to the router. Interference from microwave ovens and Bluetooth devices can also affect the stability of the 2.4 GHz signal.
⚠️ Please note: Wireless module specifications may vary depending on the region where the device is sold. If standard methods don't work, please consult the official documentation from the TV manufacturer.
In some cases, resetting the network settings on your smartphone can help. Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothThis action will delete saved passwords, but often solves connection problems.
Comparison of connection methods
The best method depends on your goals. If you simply need to share photos with friends or a presentation, Miracast is suitable. For watching movies, Chromecast is better, as it uses less battery and provides a better picture.
Gamers should pay attention to input lag. Wireless technologies always introduce some delay, so for fast-paced shooters, it's best to use a wired connection or low-latency game modes if your TV supports them.
Don't forget that Xiaomi Redmi 8 — a budget device, and its processor may not be able to handle high-resolution video encoding in real time when other applications are actively used.
Frequently Asked Questions (FAQ)
Why doesn't my Xiaomi phone see my TV in the list of available devices?
Most often, the problem is that the devices are connected to different Wi-Fi networks (for example, one 2.4 GHz network, another 5 GHz, and the router is isolating them). Also, check whether DLNA or Screen Mirroring is enabled in the TV settings.
Is it possible to connect Redmi 8 to a TV without the Internet, only via Wi-Fi?
Yes, many technologies (Miracast, Wi-Fi Direct) work locally and don't require access to the global network. The main thing is that the Wi-Fi modules on both devices are active and visible to each other.
Does screen mirroring affect battery drain?
Yes, active Wi-Fi video streaming and image encoding significantly drain the battery. It's recommended to keep your phone charged during extended viewing.
How can I improve the quality of a picture if it looks blurry?
Make sure the content is high quality to begin with. Screen mirroring may automatically reduce the resolution to ensure a smooth experience. Try changing the screen resolution in developer settings or using streaming apps instead of full screen mirroring.
