Modern smartphones such as Xiaomi Redmi 10, boast powerful multimedia capabilities, highly detailed screens, and excellent sound. However, even a high-quality 6.5-inch display can't compete with a full-fledged home theater or large-screen Smart TV when it comes to watching movies with the family or sharing vacation photos.
Fortunately, the era of tangled cables and searching for HDMI adapters is gradually becoming a thing of the past. Wireless data transfer technologies allow you to instantly stream content from your mobile device to the big screen using only a local network. For owners of Android devices, particularly the popular model Redmi 10, there are several native and third-party methods available to accomplish this task.
In this article, we'll cover all current connection methods in detail, analyze the features of the MIUI operating system, and help you set up a stable video signal. You'll learn how to use built-in system features, third-party apps, and specific protocols to achieve the best image quality.
⚠️ Attention: The MIUI interface may vary slightly depending on the firmware version (Global, EU, China) and the year the update was released. The layout of menu items may vary, but the operating logic remains the same.
Technical requirements and equipment preparation
Before you begin setting up the stream, you need to make sure all components of your multimedia system are ready to work. A fundamental requirement for most wireless methods is that both devices are on the same local network. This means that Xiaomi Redmi 10, and your Smart TV must be connected to the same router.
Using a guest Wi-Fi network or separating the 2.4 GHz and 5 GHz frequencies into different SSIDs (network names) can cause devices to "not see" each other. For stable high-resolution video streaming, especially in 4K or HDR, it is highly recommended to use the 5 GHz band, which provides higher throughput.
It's also worth checking the operating system version on your smartphone. Redmi 10 You must have a current version of Android installed, not lower than 11 (or newer, depending on updates), as older versions may have limitations in supporting modern codecs and broadcast protocols, such as Miracast.
☑️ Check before connection
Please remember that wireless video streaming is a power-intensive process. Make sure your device's battery is charged. Xiaomi is at least 30-40%, or connect the device to a charger to avoid sudden shutdown at the most inopportune moment.
Using the built-in "Broadcast" function (Miracast)
The most common and frequently used method is technology Miracast, which is in the interface Xiaomi Simply called "Broadcast," this standard allows you to mirror your smartphone's screen to your TV in real time without lag, making it ideal for showing presentations, playing games, or viewing photo albums.
To activate the function, pull down the notification shade Redmi 10 Double-swipe down. In the quick settings menu that opens, find the icon called "Broadcast" (sometimes it's hidden in a second tab that you need to swipe left to open). If you don't see the icon, tap the pencil or three dots to edit the panel and add this item.
Once activated, the smartphone will begin searching for available devices. A connection confirmation prompt may also appear on the TV screen, which must be accepted with the remote control. The entire process typically takes no more than 10-15 seconds with a stable signal.
Why wasn't the TV found?
If the search doesn't yield any results, make sure Screen Mirroring, AnyView Cast, Miracast, or Wireless Display is enabled on your TV. This option may have different names on different TV models (Samsung, LG, Sony) and is often located in the "Network" or "Connections" menu.
It's worth noting an important detail: when mirroring your screen via Miracast, your smartphone may become warm. This is a normal physical reaction of the processor and Wi-Fi module to intensive workloads. If you plan on a long session, ensure the device is well ventilated.
Streaming via Google Home and Chromecast
The Google ecosystem offers an alternative and often more stable way to connect, especially if your TV supports the built-in platform. Chromecast built-in or Android TV. Unlike Miracast, which simply mirrors the image, Chromecast lets you control content using your phone as a remote.
To implement this method on your Xiaomi Redmi 10 the application must be installed Google HomeIt's often preinstalled, but if not, download it from the Play Store. After installation, launch the app and sign in to your Google account.
In the main menu, you'll see a list of available devices. Find your TV and tap it. In the control menu that opens, select "Cast my screen." Your phone's image will instantly appear on the big screen.
| Characteristic | Miracast (Broadcast) | Google Chromecast |
|---|---|---|
| Connection type | Direct (P2P) | Via cloud/router |
| Impact on battery | High | Average |
| Picture quality | Depends on the signal | Adaptive (up to 4K) |
| Work in the background | No (screen active) | Yes (can be folded) |
The advantage of Chromecast is that once playback starts, you can minimize the app or even lock your phone's screen, and the video will continue playing on your TV. This frees up your smartphone for other tasks, such as replying to messages in instant messaging apps.
Stream from YouTube, Netflix, and other apps
The best way to view video content is to use the built-in casting feature in the video player apps themselves. Services like YouTube, Netflix, IVI or Okko have their own transfer mechanism, which often works better than the system's screen mirroring.
Open an app like YouTube on your Redmi 10In the upper right corner of the interface, you'll see a distinctive rectangle icon with waves (Chromecast icon). Clicking it will start a search for compatible devices on the network.
Select your TV from the list. It's important to understand that in this case, your phone only acts as a remote control: it sends a command to the TV, which then downloads the video stream from the internet. This is critical for saving data and battery life.
⚠️ Attention: Make sure your phone and TV app accounts are logged in using the same email address. Otherwise, some services may block your ability to manage content.
If the casting icon is grayed out or inactive, it means the device wasn't found. Check if the TV is connected to the same Wi-Fi network as your smartphone. Different subnets (such as guest and main) are often isolated from each other by router settings.
Third-party applications for complex cases
Sometimes standard tools Xiaomi Or Smart TV protocols may not work correctly due to software errors or specific network security settings. In such situations, specialized aggregator apps that can find a compromise between different protocols come to the rescue.
One of the most popular solutions is the application Web Video Caster or Tv CastThese programs allow you to stream not only videos from built-in browsers, but also files stored on your phone's memory, as well as content from websites that don't have native Chromecast support.
The setup process is simple: install the app on Redmi 10, and if needed, a companion app for your TV (although the built-in DLNA renderer is often sufficient). Run a network scan, select the device, and start playback.
Another option for advanced users is to use media servers such as Plex or KodiBy installing the server component on a PC or NAS and the client component on a TV and phone, you'll have a unified media library accessible from all devices in the home.
Troubleshooting and Common Mistakes
Despite the simplicity of the technology, users often encounter issues such as choppy images, audio and video desynchronization, or a complete failure of devices to communicate with each other. The first step in troubleshooting should always be rebooting the router. The Wi-Fi network cache can become overloaded, causing packet transmission failures.
If the video is streaming but constantly buffering (the loading wheel is spinning), the problem lies with your Wi-Fi connection speed. Try moving closer to the router or turning off other devices consuming bandwidth (torrents, game downloads).
If the audio lags behind the picture by a few seconds, try changing the audio output settings in the app or on the TV itself. Sometimes switching from 5.1 surround sound to 2.0 stereo resolves the decoding lag issue.
Why does the sound disappear when connecting via Miracast?
Often, when mirroring your screen, the audio remains on your phone instead of going to your TV. Check the audio settings in the "Cast" menu or switch the audio output in the Bluetooth/Audio settings on your output device.
Is it possible to connect a phone to a TV without a Wi-Fi router?
Yes, if your TV supports Wi-Fi Direct technology. In this case, the phone connects directly to the TV's Wi-Fi module, creating a local network without the need for an external router.
Does the connection affect internet speed?
When using Chromecast (casting from apps), your phone's internet speed isn't consumed because the TV downloads the content itself. When mirroring your screen (Miracast), your phone can still use the internet, but the majority of the load falls on your Wi-Fi channel.
Keep in mind that TV software updates are less frequent than smartphone software. If you still can't connect after trying all these steps, check for firmware updates for your TV model in the system settings menu.
