Modern smartphones like the Xiaomi Redmi Note 8 Pro have powerful multimedia capabilities that you often want to show on the big screen. Wireless display technology allows you to stream an image from your smartphone to your TV or monitor without using unnecessary cables. This is especially convenient for watching movies, presenting or showing photos to friends. Owners of devices based on the MIUI shell can come across different names for this feature, but the essence remains the same – transferring a video signal using Miracast or Wi-Fi Direct protocols.
The setup process can be confusing because of the manufacturer’s shell. Xiaomi often hides the necessary options in different menu sections or uses specific terminology. In this article, we will discuss in detail all the ways to activate a broadcast, from built-in system tools to specialized applications. You will learn how to ensure a stable connection and avoid typical connection errors.
Before you start setting up, you need to make sure your hardware is ready to go. Wireless data transfer requires not only a compatible smartphone, but also the appropriate receiving device. Most modern Smart TVs maintain the necessary standards, but older models may require additional adapters. Let's look at a step-by-step algorithm for successful device synchronization.
Equipment preparation and network requirements
The first and most important condition for the successful operation of the Wireless Display feature is the presence of a single local network. Your Xiaomi Redmi Note 8 Pro and TV (or set-top box) must be connected to the same Wi-Fi router. If the devices are on different subnets or one of them will use mobile Internet, detection is impossible. Check the connection status in the settings of your smartphone’s wireless networks.
Xiaomi regularly releases security and functionality updates that can improve the stability of the Wi-Fi Direct module. It is recommended to check for updates in the Settings menu → About Phone → MIUI version. If the system offers to install a new version, it is better to do this before setting up multimedia functions.
An important aspect is the support of Miracast TVs. Most current models from Samsung, LG, Sony and other brands have this out of the box feature. On the TV, you may need to run a special app, often called Screen Share, Translation, or Wireless Display. Without active standby on the TV side, the smartphone will not be able to find the target device to connect to.
⚠️ Note: Guest Wi-Fi in public places (hotels, cafes) often blocks the ability to interact between devices within the network for security reasons.
To ensure smooth image transfer without delays and compression artifacts, it is advisable to use the 5GHz frequency band if your router and TV support this standard, this is especially true when streaming video in high resolution 1080p or 4K, which is capable of producing the Helio G90T processor installed in the Redmi Note 8 Pro.
☑️ Checking connection readiness
Built-in Translation function in MIUI
In the Android operating system with the MIUI shell installed on the Xiaomi Redmi Note 8 Pro, there is a regular tool for displaying an image. You can find it through the control panel. Swipe down from the top edge of the screen to open the "Stork", and find an icon called "Broadcast" (or "Cast" on some versions of the firmware). If the icon is not in quick access, click on the menu edit button (usually a pencil icon or three dots) and add it from there.
Once activated, the smartphone will start looking for available devices within range. A list of found TVs and media consoles will appear on the screen. Select the desired device from the list. A request for confirmation of connection may appear on the TV screen - it must be confirmed by the remote control. After that, the image from the smartphone screen is fully duplicated on the large screen.
The MIUI Broadcast feature works at the system level, which allows you to output not only video, but also the game interface, app menus and desktop. However, it is worth considering that when you use your smartphone actively during the broadcast, notifications and incoming calls will also be displayed on the TV. For comfortable video viewing, it is better to turn on the Do Not Disturb mode.
💡
If Translation doesn't find the TV, try restarting the router. Often, the router's network protocols freeze and prevent devices from being detected through Miracast.
Some versions of firmware may have a different name or a deeper hidden setting. Alternative path to setup: Go to Settings → Connection & Sharing → Broadcast. Here you can see a more detailed connection status and a list of previously used devices. If this menu displays a message about no devices, check again for the TV to connect to the same Wi-Fi network.
Use of the Mi Remote app and alternatives
If the standard streaming feature doesn’t work or suits you for some reason, you can use the Mi Remote app, which is the company’s main task – control the infrared port, in some regions and versions it is integrated with the functions of the smart home and can help you set up your Android TV connection. Open the application and try to add a new device by choosing the “TV” type.
However, a more effective solution for complex cases is the use of specialized relay applications such as Google Home.This is the official application from Android developers, which works perfectly on the Xiaomi Redmi Note 8 Pro. After installation and authorization in a Google account, the application will scan the network and offer to broadcast the screen to Chromecast built-in devices that are built into many modern TVs.
The way you connect through Google Home is by opening an app, finding your TV in the list of devices, clicking on it and selecting the option to Broadcast the screen, which has the advantage of being highly stable and supporting a wide range of multimedia formats, and allowing you to control volume and pause play directly from the lock screen.
| Connection method | Type of protocol | Stability | Delay (Latency) |
|---|---|---|---|
| Staff "Translation" | Miracast / Wi-Fi Direct | Tall. | Low. |
| Google Home | Chromecast built-in | Very high. | Medium |
| Third-party annexes | DLNA / Proprietary | Medium | Tall. |
It is worth noting that the use of third-party software can consume more resources of the Helio G90T processor and battery power. During long-term broadcast through heavy applications, the smartphone can heat up. In such cases, it is recommended to reduce the brightness of the smartphone screen, since it still burns during the transmission of the image, which creates an extra load on the battery.
Setting up the TV to receive the signal
The success of the connection depends on 50% of the correct settings of the receiving device. On TVs of different brands, the signal reception function can be called differently. For example, on Samsung devices, it is often hidden in the Connection List menu or called by the Source button on the remote where you choose Screen Mirroring. On LG TVs with a WebOS system, the application is called Screen Share.
For Android TVs (Sony, Philips, Xiaomi Mi TV), a separate app doesn’t always have to be run — it’s enough to have the TV on and connected to Wi-Fi. However, system settings sometimes require you to explicitly allow unknown devices to connect. Go to Settings → Apps → Google Chromecast built-in (or similar) and make sure the app isn’t disabled and has the necessary permissions.
⚠️ Note: On some TV models, the wireless display function may not work if the USB-port has external media drives inserted. Try removing flash drives before searching for the device.
If the TV is old and doesn't have smart features, an external adapter can help solve the problem. HDMI-Miracast-enabled whistles or Android-enabled consoles, and these devices are connected to the device. HDMI-The TV port and create an access point or connect to your Wi-Fi, becoming visible to the Xiaomi Redmi Note 8 Pro as a separate display.
Solving Connection Problems
Despite the simplicity of the technology, users often experience a situation where devices cannot see each other. IP-Try to forget the Wi-Fi network on your smartphone (Settings) → Wi-Fi → Your network. → Forget) and reconnect by entering a password, which will update the network stack and may solve the visibility problem.
Another common problem is antivirus software or router security settings. Some routers have an AP Isolation feature that prevents devices within the same network from communicating with each other. Go to the router settings (usually through the browser at 192.168.0.1 or 192.168.1.1) and make sure that this feature is disabled.
What to do if the image twitches?
If audio is broadcast and video is not available (black screen), the problem may be protecting HDCP content. Some streaming services (Netflix, Disney+) block the output of protected content to unlicensed or wireless displays, in which case only cable connection or use of the built-in service application directly on the Smart TV can help.
If nothing works, try resetting your network settings on your smartphone. Go to Settings → Connection & Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Note that this action will remove all stored Wi-Fi and Bluetooth pairing passwords, but often eliminates deep software errors on Xiaomi’s network modules.
💡
Network resets are a radical, but often the only way to fix device discovery protocol errors when software methods don’t help.
Third-party broadcast applications
When MIUI and standard protocols fail, third-party apps come to the rescue, and one of the most popular and functional solutions is Web Video Caster or LocalCast, which allows you to stream not only the entire screen, but also specific video files, photos or music directly to the TV, bypassing buffering via your smartphone.
Another powerful tool is AirScreen (if you want to take a signal to an Android set-top box) or, conversely, client applications for old TVs. For Xiaomi Redmi Note 8 Pro, Cast to TV is great. It automatically scans the network and offers the most suitable connection protocols. The interface of such programs is usually intuitive: select a file or screen mode and press the connection button.
Using third-party software has the advantage of additional codecs, so if your TV doesn't understand the format of the video you're trying to run from your smartphone, the translation app can recode the stream on the fly, which reduces the workload on the TV's processor by taking the video processing task on itself.
⚠️ Warning: When installing third-party apps from unofficial sources, be careful. download programs only from a trusted Google Play store to avoid malware that can intercept your screen data.
Some apps offer paid subscriptions to remove ads or improve stream quality.A one-time use is often enough of a free version with restrictions. However, for regular use of a wireless display as the main way to view content, it makes sense to consider buying a quality display. HDMI-Adapter that will provide stability without hanging.
