Modern smartphones like the Xiaomi Redmi 8T have powerful screens and high-resolution performance, but for a comfortable viewing of movies, photos or games on a large screen, it often becomes necessary to stream an image from a mobile device to a TV. WiFi is the most convenient and aesthetic solution, eliminating the need to search for adapter cables.
The connection process does not require deep technical knowledge, but has its own nuances depending on the model of your TV and the version of the operating system. In this article, we will discuss in detail all available methods for syncing Redmi 8T with the TV panel using built-in MIUI functions and third-party applications. You will learn how to set up a stable connection and avoid common problems with signal latency.
For successful wireless broadcasting, it is critical that both devices be on a single LAN, a fundamental requirement of Miracast technology and DLNA, which underpin most connectivity methods. If a router distributes a network at 5 GHz, the data rate will be higher, allowing for a smoother picture without jerking.
Preparation of devices for wireless connection
Before you start setting up software settings, you need to make sure that the hardware is physically ready. Your Xiaomi Redmi 8T and TV must be on and in the zone of confident reception of the wireless signal. The distance between the router and the devices must not exceed reasonable limits, otherwise data packet loss is possible.
Check that the TV has activated external signal reception mode. In modern Smart TVs, this feature is often turned on by default, but some models require you to manually select the source of the signal or activate the Screen Mirroring function in the network settings menu. Older TV models may require an external adapter connection.
⚠️ Note: If your router supports 2.4 GHz and 5 GHz band splits with different network names (SSID), Make sure your phone and TV are connected to the same frequency, preferably 5GHz for high bandwidth.
Software updates are another important step in preparation. In your phone settings, go to About Phone and check for MIUI updates. The current firmware version contains corrections for communication protocol errors, which directly affects connection stability.
☑️ Checking before connection
Use of the built-in Mi Cast function
The easiest and most native way to stream the Redmi 8T screen is to use the built-in Mi Cast utility, which is based on the Miracast standard and does not require any additional software installation, and is ideal for mirroring everything that happens on the smartphone screen.
To start, open the notification curtain control panel and look for the Translation or Mi Cast icon. If the icon is not available quickly, go to Settings menu → Connection and Sharing → Broadcast. The system will begin automatically searching for available devices on the network.
When your TV name appears on the list, tap it to initiate a connection. A connection confirmation request may appear on the TV screen, which must be received by the remote control, and then the image from the phone will appear on the large screen.
- 📺 Quality: Support for permission before 1080p 60 frames per second.
- 🔋 Energy consumption: The mode actively consumes battery power, it is recommended to connect to the charger.
- 🎮 Delay: Minimum input delay, for presentations, but can be noticeable in dynamic games.
It is important to note that when using Mi Cast, the phone’s screen may go out to save power, but the broadcast will continue.If the image is interrupted, try to reduce the distance to the router or close the background apps consuming traffic.
💡
To reduce the latency of sound and video, close all heavy applications running in the background and turn off downloads on other devices on the network.
Broadcasting via Google Chromecast
Many modern TVs have built-in support for Google Chromecast technology. Unlike Miracast, this method allows you to stream content directly from apps without loading the phone's processor with a rendering of the entire interface, which is especially convenient for watching videos from YouTube, Netflix or online cinemas.
Make sure your Redmi 8T has Google Play services installed. Open the app you want to display content from, such as YouTube. Find the broadcast icon (a rectangle with waves in the corner) and select your TV from the list.
The main advantage of this method is that the phone acts only as a remote control, so you can fold the application, respond to messages or even turn off the screen of the smartphone, and the video on the TV will play independently, which significantly saves battery power.
| Parameter | Mi Cast (Miracast) | Chromecast |
|---|---|---|
| Type of transmission | Screen mirroring | Streaming content transfer |
| Dependence on the phone | High (screen active) | Low (you can use your phone) |
| Video quality | Depends on the WiFi signal. | Stable, depending on the speed of the Internet |
| Support for applications | All applications | Only supporting Cast |
If there is no built-in Chromecast in the TV, you can purchase an external dongle adapter that connects to the TV. HDMI-For Xiaomi Redmi. 8T This is a great option because Android has a deep integration with the Google ecosystem.
Application of third-party applications for Smart TV
When built-in methods don’t work or the TV is a less common brand (like older Dexp or BBK models), universal apps come to the rescue. One of the most popular Android solutions is the TV Cast app or Web Video Caster.
Install the selected app from the Google Play Store on your Redmi 8T. Launch the program and follow the instructions on the screen. Usually you need to open the browser inside the application and go to the site with the video, then click the TV connection button.
These apps often can stream not only video files, but also photos, music and even web pages. They can convert streaming video on the fly, providing compatibility with TVs that do not support modern codecs.
⚠️ Warning: Free versions of third-party apps often contain ads. Be careful when pressing buttons in the interface so as not to start installing unnecessary software.
Some TV makers have their own smartphone apps, such as LG TV Plus for LG and SmartThings for Samsung. While Xiaomi is keen to develop its ekosystem, using universal solutions often gives more flexible settings.
Solution and unstable connection
Even with the right setup, users can experience problems: the image twitches, the sound lags behind the video, or the phone can’t see the TV at all, most often because of congestion of the WiFi channel or router settings.
Try rebooting your router, phone, and TV, and this trivial action clears the cache of network modules and eliminates time conflicts. IP-Also make sure that the router has disabled the Customer Isolation feature» (AP Isolation, which prevents devices within the network from seeing each other.
- 🔄 Reboot: Complete shutdown from the socket for 10 seconds.
- 📶 WiFi Channel: Switch routers to channels 1, 6, or 11 if neighboring networks cause interference.
- 🛡️ Antivirus: Temporarily turn off the firewall on your phone if it blocks local connections.
If the problem persists, check the date and time on both devices. Time out-of-synchronization can cause security certificate errors, causing handshake connection to fail.

Alternative Connection Options Without WiFi
If the wireless network is unavailable or is not running smoothly, there is always a wired option left. - Xiaomi Redmi 8T portable USB Type-C, which unfortunately does not support video output directly (MHL/Alt Therefore, a special adapter will be required for a wired connection.
You're gonna need an adapter. USB-C to HDMI. However, since direct image output is not supported at the hardware level of this processor, such adapters work only as external graphics cards and require the installation of drivers, which is poorly implemented on Android. DLNA via a local network without access to the Internet.
To do this, create a local hotspot on your phone and connect to it the TV (if it can work as a WiFi client), or use a router without connecting to the provider. Video files can be opened through the built-in MIUI Video player and select the device for broadcasting.
💡
Wired connectivity via an adapter for the Redmi 8T is often less efficient and more costly than setting up a stable WiFi connection or using a Chromecast.
