Modern smartphones such as Xiaomi Redmi 8, have powerful screens, but a 6-inch diagonal is often insufficient for viewing family videos or photos. Fortunately, wireless data transfer technologies allow you to instantly stream images from a mobile device to a large TV screen, eliminating the need to search for cables and adapters. This process, known as screencasting or screen mirroring, has become the standard for multimedia systems.
Android device owners can use several built-in protocols to communicate. These are most often related to technologies Miracast or Google Cast, which are supported by most modern Smart TVs. You don't need to be a network expert to establish a connection; just follow the logical steps.
Before you begin setup, make sure both devices—your smartphone and TV—are connected to the same wireless network. A shared network environment is the foundation for devices to discover each other. If your router broadcasts two networks (2.4 GHz and 5 GHz), try connecting your devices to one of them, although modern routers often combine them into a single logical network.
Preparing Redmi 8 and TV for synchronization
The first step is to check your basic settings Redmi 8Make sure WiFi is enabled and your phone is successfully connected to your home network. In some cases, Android may ask for permission to search for devices on your local network, and you'll need to confirm this request.
On the TV side, the situation may vary depending on the manufacturer and operating system version. On Smart TVs running Android TV or Google TV The signal reception function is often enabled by default. However, on panels from other brands, such as Samsung or LG, you may need to manually launch the receiver app.
⚠️ Note: If your TV doesn't have built-in Smart TV support, a direct wireless connection is not possible. In this case, you will need to use an external set-top box, such as Chromecast or Apple TV.
Check that your TV isn't using any power-saving modes, which could block incoming connections. It's also worth making sure your TV's software is updated to the latest version, as older firmware versions may contain vulnerabilities in data transfer protocols.
Using the built-in "Cast" feature in MIUI
shell MIUIThe Redmi 8's built-in display management toolkit comes with its own tools for managing external displays. You don't need to download any third-party apps to access it; everything you need is built into the system. This is the most direct way to mirror your screen.
Open the Control Center by swiping down from the top and find the "Cast" icon. If it's not on the first screen, tap the edit menu button and add it. Once activated, your phone will begin searching for available receivers on the network.
- 📱 Tap the "Broadcast" icon in the notification bar.
- 📡 Wait until the system detects your TV in the list of available devices.
- 🖥️ Tap your TV model name to start pairing.
- 🔒 If a confirmation code appears on the TV screen, enter it on your smartphone.
It's important to note that the quality of the transmitted image directly depends on the strength of the WiFi signal. If you notice delays or choppiness, try moving closer to the router or clearing the channel of heavy loads, such as downloading files from other devices.
Broadcast via the Google Home app
If the standard MIUI tools do not find the TV or work unstable, the best solution is to use the official application from Google. The program Google Home It is a universal remote control for the smart home ecosystem and does an excellent job of broadcasting.
Download and install the app from the store Google PlayOnce launched, it will automatically scan the network and detect all compatible devices, including TVs with Chromecast built-in support. This is especially important for TVs that don't natively support the Miracast protocol.
To start casting, click your TV icon in the list of devices, then select "Cast Screen." The image from your Redmi 8 will instantly appear on the large panel. This method often provides a more stable connection and better color reproduction.

Specifics of connecting to TVs of different brands
The setup process may vary slightly depending on your TV brand. Manufacturers use different names for wireless connection features, which can sometimes cause confusion among users.
On devices Samsung This function is called Smart ViewYou need to find the appropriate app on your TV and launch it before searching from your phone. TVs LG use technology Screen Share, which also requires preliminary launch through the application menu.
| TV brand | Function name | Peculiarities |
|---|---|---|
| Samsung | Smart View | Requires confirmation on the remote control |
| LG | Screen Share | Miracast support |
| Sony | Screen Mirroring | Works through network settings |
| Xiaomi / Mi TV | Mi Remote / Cast | Deep integration with MIUI |
For owners of TVs with built-in Android TV The luckiest ones are: they simply need to confirm the connection request that appears on the screen. No further action from the remote control is usually required.
What to do if the TV is not visible?
Make sure Client Isolation is disabled on your router. This setting prevents devices on the same network from seeing each other, which prevents your phone from searching for the TV.
Image quality and lag issues
Even with a proper connection, users may experience audio and video desynchronization or low image resolution. This is often due to wireless channel congestion or low processor speed when encoding the video stream.
Try reducing the network load by disconnecting other devices from WiFi. It's also a good idea to change the output resolution in the streaming settings on your Redmi 8, if this option is available in the specific receiver app. Sometimes, rebooting the router helps, as this clears the channels of interference from neighboring devices.
⚠️ Please note: Operating system and TV interfaces are subject to update. Button locations and menu item names may differ from those described in the instructions. Always consult the manufacturer's latest manuals.
If you're using a dual-band router, make sure both your phone and TV are connected to the same frequency (preferably 5GHz for video streaming, as this band provides higher throughput).
Alternative wireless connection methods
In cases where standard methods don't work, you can resort to third-party applications. Programs like AirScreen or ApowerMirror are capable of working wonders by bridging the gap between otherwise incompatible protocols.
These apps can be installed on both your TV (via the TV app store) and your smartphone. They create a virtual receiver that emulates standard protocols, allowing you to connect even older TV models.
- 📥 Install the receiver app on your TV from its store.
- 📲 Download the companion app on your Redmi 8.
- 🔗 Scan the QR code from the TV screen or enter the IP address manually.
- 🎬 Enjoy content using advanced control settings.
It's worth keeping in mind that free versions of such programs often have session time limits or contain ads. Permanent use may require purchasing a license.
Frequently Asked Questions (FAQ)
Is it possible to connect Redmi 8 to a TV without WiFi?
Without a WiFi network, a direct wireless connection is impossible, as it serves as the data transmission medium. However, you can use WiFi Direct, which creates a direct connection between your phone and TV without a router, if both devices support this technology. A cable connection via a USB-C to HDMI adapter is also an option, but the Redmi 8 may not support video output through the charging port.
Why is there only a picture but no sound?
This is a common issue related to permissions or app-specific settings. Check to see if the volume on the TV itself is turned down separately from your phone's volume. Also, try restarting the app you're streaming from (such as YouTube or a browser), as sometimes the audio stream doesn't automatically switch to the external speakers.
Does connecting a phone to a TV affect internet speed?
Yes, streaming high-quality video (especially 4K or FullHD) puts a significant strain on your local network. If your internet connection is limited, page loading speeds on other devices may temporarily decrease, as the video stream requires a stable and high bandwidth.
Will my phone screen work during the broadcast?
When using Miracast, your phone's screen usually stays lit and displays the same content as your TV. However, some apps (such as YouTube or Netflix) have a background feature: you can minimize the video or lock the screen, and playback on your TV will continue, saving battery life.
