Modern smartphones such as Redmi 8 ProMobile devices have become powerful multimedia centers capable of playing high-definition content. However, the small screen of a mobile device is often insufficient for comfortable viewing of movies or presentations. Fortunately, wireless data transmission technologies make it easy to stream images to a large TV screen without the need for unnecessary cables.
There are several proven synchronization methods, each with its own advantages. Device owners Xiaomi can use built-in system functions MIUI, third-party apps, or Smart TV capabilities. The specific method you choose depends on the year of your TV and whether it supports the required protocols. Miracast or Google Cast.
In this article, we'll cover all current connection methods in detail, from standard settings to advanced methods for experienced users. You'll learn how to ensure a stable video stream and avoid lag. For wireless broadcasting to work correctly, both devices must be on the same local Wi-Fi network.
Preparing equipment and setting up the network
Before you begin setup, make sure your home network is ready to handle heavy video streaming. The wireless connection is a critical element of the entire system, and any interference can cause audio and video to become out of sync. Make sure your router is stable and transmitting a signal at the correct frequency. 2.4 GHz or 5 GHz.
The ideal option would be to use a dual-band router that supports the standard 802.11ac (Wi-Fi 5) or newer. This will ensure sufficient channel bandwidth. If your Redmi 8 Pro and the TV are located far from the router, the picture quality may decrease, so it is recommended to reduce the distance between the devices or use Wi-Fi repeater.
⚠️ Important: If your router broadcasts two different networks (for example, "Home_2.4" and "Home_5G"), be sure to connect both your phone and TV to the same one. Being on different subnets often blocks device detection.
It's also worth checking for software updates on both devices. Manufacturers regularly release patches that improve the stability of wireless modules. On a smartphone, this can be done through the menu. Settings → About phone → MIUI version.
Using the built-in "Cast" feature in MIUI
shell MIUI, installed on Redmi 8 Pro, has a built-in screen mirroring tool. This method is the simplest and doesn't require any additional software. It's based on the protocol Miracast, which is supported by most modern TVs.
To start the process, look for the "Broadcast" icon in the notification shade (sometimes it's hidden in an additional menu that opens with a swipe down). If you don't see the icon, go to Settings → Connection and Sharing → BroadcastThe system will begin searching for available devices within the network range.
☑️ Check before connection
When the list of available receivers appears on your smartphone screen, select the name of your TV. A connection permission request may appear on the TV screen, which you'll need to confirm with the remote control. After that, the image from Redmi 8 Pro will appear on the big screen.
It is worth noting that when using this method, the phone may heat up, as the video encoding process requires resources. processorThe smartphone screen will also remain lit continuously unless the screen lock feature is activated during the broadcast.
Streaming via Google Home and Chromecast
If your TV has a built-in module Chromecast or you are using an external Google set-top box, the best solution would be an app Google HomeIt provides a more stable connection and supports higher resolution streaming compared to standard Miracast.
Download the app Google Home from the official store Play MarketAfter installation, open the program and find your TV in the list of devices. Click on the device icon, then select the "Cast screen" button.
⚠️ Note: When using Chromecast, picture quality depends on your internet speed if you're streaming online content. For local videos from your phone's storage, your router speed is more important than your ISP's speed.
Unlike standard streaming, this technology allows the phone to act as a remote control while the TV downloads content or directly mirrors the stream. This reduces battery drain. Redmi 8 Pro.
The advantage of this method is the ability to control the stream from other devices on the network. You can start a video on your TV and use your phone to type or make calls without interrupting playback, provided the content supports this feature (for example, YouTube).
Stream videos from YouTube and Netflix apps
The most popular usage scenario is watching videos from online services. Applications YouTube, Netflix, Ivi and others have a built-in Casts feature that works regardless of the system display settings. This often provides better picture quality, as the video is transmitted directly from the server to the TV.
Open an application, for example, YouTube on yours Redmi 8 ProAt the top of the interface or in the corner of the video player, look for the rectangle icon with waves (Chromecast icon). Clicking it will display a list of available devices.
What should I do if the broadcast icon doesn't appear?
The icon may not appear if the devices are on different Wi-Fi networks. Also, make sure the appropriate app (e.g., YouTube on TV) is open on your TV or running in the background. Restarting the router can sometimes help.
Once you select your TV, the video will start playing on the big screen, and your smartphone will become a remote control. You can pause, change the volume, rewind, or even exit the app without interruption.
It's important to understand the difference: in this case, the phone doesn't broadcast its entire screen, but merely instructs the TV to start streaming. Therefore, notifications, incoming calls, and other smartphone activity won't be visible on the TV screen, which is very convenient for maintaining privacy.
Third-party screen mirroring apps
Built-in tools don't always work correctly with older TV models or specific routers. In such cases, third-party solutions from Google PlayPopular apps like Cast to TV, AllCast or Web Video Caster may solve compatibility issues.
These programs often have their own codecs and compression algorithms, allowing them to stream formats that a standard TV player can't see. For example, you can play a video file in MKV with subtitles, and the application converts the stream on the fly.
| Application | Format support | Advertising | Peculiarities |
|---|---|---|---|
| Google Home | High (Systemic) | No | Stability, working with the ecosystem |
| AllCast | Very high | There is in | Working with local files, DLNA |
| Web Video Caster | Web Streams, Video | Eat | Streaming video from websites and bypassing blocking |
| Mi Remote | Infrared port | No | Controlling the TV as a remote control (for models with IR) |
When using third-party software, pay attention to access rights. Some applications require permission to access the local network and storage. Without these permissions Redmi 8 Pro will not be able to read the video file and transmit it to the TV.
Some apps offer paid versions without unnecessary features and with 4K support. If you plan to frequently watch movies in high definition, it might be worth considering purchasing premium access to avoid interruptions at the most inconvenient moments.
Solution: Delays and connection interruptions
The most common problem with wireless connections is audio and video desynchronization or intermittent image freezing. This phenomenon is known as lag (lag), most often caused by wireless channel congestion or a weak signal.
Try rebooting your router by unplugging it for 10-15 seconds. This will clear the device's cache and select the least congested connection channel. It's also a good idea to close background apps. Redmi 8 Pro, which may consume traffic, such as torrents or downloads from the Play Market.
⚠️ Note: TV interfaces and MIUI versions are updated regularly. The layout of menu items may differ from what's described. If you can't find the option you need, use the settings search (the magnifying glass in the corner of the settings screen).
If the problem persists, try lowering the quality of the streamed video. Instead of 4K or Full HD, select HD (720p). This will significantly reduce the load on the Wi-Fi channel. Also, check if your router has speed limits (QoS) for specific devices.
In rare cases, resetting the network settings on your phone can help. Go to Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothPlease note that after this, you will have to re-enter passwords for all saved networks.
