Modern smartphones such as Xiaomi Redmi 10, have powerful screens, but to view content in high quality, you often want to use the large TV display. Wireless connection via Wi-Fi This is the most convenient way to stream images, eliminating the need to purchase additional cables or adapters. This method allows you to instantly display photos, videos from your gallery, or even gameplay on your Smart TV.
The connection process is based on technology Miracast or DLNA, which are built into the MIUI shell. You won't need any complicated router settings if both devices are on the same local network. The main requirements are a stable wireless signal and a TV that supports wireless display.
In this article, we'll cover all screen mirroring methods in detail, troubleshoot potential connection issues, and answer frequently asked questions from Redmi 10 owners. Proper setup will ensure smooth video transmission without lag or audio desync.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure your equipment is ready to use. Xiaomi Redmi 10 Equipped with a Wi-Fi 5 (802.11ac) module, it provides sufficient bandwidth for Full HD video streaming. However, if the router is operating on the congested 2.4 GHz band, image stuttering may occur.
Make sure your TV is Smart TV and connected to the same Wi-Fi network as your smartphone. If you have a regular TV (not a Smart TV), you'll need an external set-top box, such as an Android TV Box or Chromecast, to receive the signal. With Smart TVs, built-in Miracast or AirPlay are usually sufficient.
⚠️ Important: Make sure the "AP Isolation" feature (client isolation) is not enabled on your router. This feature prevents devices on the network from seeing each other. If this option is enabled, your phone will not detect the TV.
Check the operating system version on your Redmi 10. For stable streaming functionality, we recommend updating MIUI to the latest available version via the settings menu. Older firmware versions may contain bugs that prevent external displays from being detected.
Broadcasting via the built-in "Broadcast" (Cast) function
The fastest way to display an image is to use the system function BroadcastThis method duplicates the smartphone's screen 1:1, allowing you to display any apps, interfaces, and menus. The underlying technology, Miracast, operates at the video stream level.
To launch, open the notification shade on your Redmi 10 by swiping down from the top. Find the icon labeled "Broadcast" or "Cast." If the icon isn't available in the quick access menu, tap the edit button (usually a pencil or three dots) and add it from the list of available widgets.
Once activated, the phone will begin searching for available devices. A permission request may appear on the TV screen, which must be confirmed with the remote control. Sometimes you'll need to manually launch the "Screen Share" or "Wireless Display" app on the TV itself before searching.
☑️ Check before connection
If the connection is established but the picture is lagging, try reducing the network load. Close background downloads on other devices. Quality also depends on the smartphone's processor power and the TV's ability to decode the video stream in real time.
Using the Mi Remote app and IR port
A unique feature of many Redmi models, including the Redmi 10, is the presence of a built-in IR port (InfraRed). This allows you to use your smartphone as a universal remote control even if your TV isn't connected to Wi-Fi, although a network connection is still required to stream the image.
Application Mi Remote pre-installed in the system. It not only allows you to control volume and channels but also quickly launch the image mirroring function. The app interface often includes a "Cast" button, which automatically switches the TV input to Screen Mirroring mode.
Using the IR port is especially useful if your TV remote is lost or its batteries are dead. You can easily switch signal sources (HDMI 1, HDMI 2, AV) directly from your smartphone screen to access the wireless connection menu.
What to do if the IR port does not work?
Make sure there's no protective glass or case on the top of your smartphone that's blocking the infrared diode. Also, check that the correct TV model is selected from the list in the Mi Remote app settings.
It's worth noting that the IR port is used only for control, not for video transmission. The video stream still goes through the Wi-Fi router. Therefore, the presence of an IR sensor simplifies navigation of the TV menu, but does not replace the need for a wireless network.
Streaming media via DLNA and YouTube
You don't always need to mirror your entire smartphone screen. If you want to watch a video from your gallery or streaming service, it's more efficient to use the technology. DLNA or built-in app protocols. This reduces the load on the Redmi 10's battery and processor.
In the Gallery or Mi Video app, open the desired file and find the "Cast" icon (the rectangle with waves). Your phone will offer a list of available TVs. When you select a device, the video file will be sent to the TV, and you can use your smartphone for other tasks.
The cast button works similarly in YouTube, Netflix, or online movie theater apps. Tap the Cast icon in the corner of the player. In this case, your phone acts only as a remote control, and the TV buffers the video directly from the internet, ensuring maximum quality.
| Method | Quality | Impact on battery | Best use |
|---|---|---|---|
| Miracast (Broadcast) | Depends on the network | High | Games, browser, photos |
| DLNA (Gallery) | Original file | Low | View photos/videos |
| YouTube Cast | Up to 4K | Minimum | Video streaming |
| Google Home | High | Average | Universal |
⚠️ Note: When streaming via DLNA, some video formats (such as MKV with rare codecs) may not be playable on your TV. In this case, use screen mirroring.
Setup via the Google Home app
If the standard MIUI tools are unstable or the TV is not detected, the official application comes to the rescue. Google HomeIt's available in the Play Market and is standard for the Android ecosystem. This method is often more reliable for Android TVs.
Install the app and sign in to your Google account. Google Home will automatically scan the network and find available Chromecast built-in or Android TV devices. Select your TV from the list of devices.
In the control menu that opens, tap "Cast my screen." The system will warn you that all actions on your phone will be visible on the TV. Confirm the action, and the image from your Redmi 10 will appear on the big screen.
The advantage of Google Home is the ability to control volume and adjust picture quality directly from the app. You can also create device groups if you want to stream audio to multiple speakers or TVs at once.
Solving problems and delays
The most common issue with wireless connections is audio and video desynchronization or image lag. This is critical in games, but less noticeable when watching movies. The main cause is an unstable Wi-Fi signal or interference from neighboring networks.
Try switching your router to a less congested channel or switching to the 5 GHz frequency if your Redmi 10 and router support it. The 5 GHz frequency provides higher data transfer speeds, which is critical for high-resolution video streaming.
If the image is choppy, reduce the output resolution. Some TVs have a "Game Mode" setting or picture mode that reduces frame post-processing and input lag. Restarting the router often resolves buffer freezing issues.
If you have sound but no picture (black screen), check your HDCP settings. Some content-protected apps (banking services, paid subscriptions) block screen recording and streaming for security reasons.
Alternative streaming apps
When standard tools fail, you can use third-party software. Application Web Video Caster or TV Cast It does a great job of sending videos from your browser to your TV, bypassing system limitations.
For gamers, there are specialized applications that optimize the stream to reduce latency. These may require installing a server component on a PC if the TV doesn't support a direct connection, creating a bridge between the phone and the TV.
Some users prefer to use remote desktop apps like TeamViewer or AnyDesk, installing them on their TV (if it's an Android TV). This provides full control, but requires more powerful hardware.
Why doesn't the phone see the TV in the list?
Most often, the problem is that the devices are connected to different networks (for example, one to 2.4 GHz, the other to 5 GHz, and the router is isolating them). Also, check whether your antivirus or firewall is blocking local connections (multicast).
Is it possible to connect Redmi 10 to an old TV without Smart TV?
Yes, but only through an external set-top box (Android Box, Apple TV, Chromecast) or by connecting your phone with a USB-C to HDMI cable. Without an external receiver, your old TV won't be able to receive a Wi-Fi signal.
Does broadcasting affect video quality?
When using Miracast, quality may be slightly reduced due to real-time video stream compression. With DLNA and YouTube Cast, the original quality is preserved, as the file or stream is transmitted directly.
Is it safe to stream personal photos to someone else's TV?
If you're on a public network (such as a hotel or cafe), make sure you're using a secure connection. On a home network, the risk is minimal, but always check the name of the device you're connecting to.
