Modern Xiaomi Redmi series smartphones boast powerful screens and multimedia capabilities, but sometimes a 6-inch diagonal isn't enough for comfortable movie viewing or presenting photos to a large group. In such situations, wireless image streaming technology comes to the rescue, allowing you to instantly stream content from your mobile device to a large TV screen. Wi-Fi connections For these purposes, it is the most optimal solution, since it does not require unnecessary wires and provides high data transfer speeds.
The process of synchronizing devices is based on standard protocols such as Miracast, DLNA or proprietary solutions from Google, which are already built into the operating system. Android and the shell MIUI or HyperOSYou don't need to be a networking expert to establish a stable connection between your gadget and your home theater system. Simply ensure both devices are on the same local network and follow a few simple steps in the settings menu.
In this article, we'll take a detailed look at all available connection methods, address potential compatibility issues, and offer solutions for situations where standard methods don't work. We'll cover both built-in system features and third-party apps that may be useful for owners of TVs of various vintages. The key to successful broadcasting is that both devices must be operating on the same Wi-Fi router subnet, otherwise detection will be impossible.
Technical requirements and equipment preparation
Before setting up, you need to ensure your equipment is technically ready to transmit a video stream. Most modern TVs released after 2015 have built-in Wi-Fi and support wireless display standards. However, older models may require an additional adapter or a Wi-Fi-enabled HDMI cable.
Redmi smartphones running Android have a built-in "Broadcast" or "Wireless Monitor" feature. For this feature to work properly, it's important that the router supports the following standards. 802.11n or higher, as older Wi-Fi versions may not provide sufficient bandwidth for high-resolution video. It's also worth noting that the phone's processor speed and RAM affect the smoothness of playback.
⚠️ Important: If your router broadcasts two networks (2.4 GHz and 5 GHz) with different names, make sure both your phone and TV are connected to the same frequency. Sometimes a mixed connection (one device on 2.4 GHz, the other on 5 GHz) can block devices from being detected on the local network.
Also check the software version on both devices. Manufacturers frequently release updates that improve connection stability and add support for new codecs. On Smart TVs, updates usually occur automatically or through the support menu in the settings.
Using the built-in "Cast" feature in MIUI
The easiest and fastest way to mirror an image is to use the native Xiaomi app feature. This option implements the Miracast protocol, allowing you to mirror your smartphone's screen to a TV without installing any additional software. The process is extremely simple and takes less than a minute.
To get started, pull down the notification shade on your Redmi and find the "Cast" icon. If it's not on the first screen, tap the panel editing button (usually a pencil or three dots) and drag the icon to the active area. Once activated, your phone will begin searching for available devices within range.
Once your TV appears in the list, tap its name. A connection confirmation prompt may appear on the TV screen, which you'll need to confirm with your remote. After that, the image from your phone will be copied completely to the big screen.
Please note that when using this method, your phone's screen must be on. If you lock your phone, the streaming may be interrupted, although some TV models allow video playback to continue in the background. You can control playback using the on-screen buttons or the physical volume button.
Setup via the Google Home app
If the built-in function doesn't work for some reason, or your TV primarily supports Chromecast built-in technology, the official app is the best solution. Google HomeIt comes pre-installed on many smartphones, but if you don't have it, you can download it for free from the store. Play Market.
The app automatically scans the network and finds all Google Cast devices, including TVs, media players, and smart speakers. The setup process is as follows:
- 📱 Open the Google Home app on your Redmi.
- 📺 Find your TV in the list (it should be displayed with a TV icon).
- 🖥️ Tap on the device and select "Cast screen" or "Cast audio/video".
- ✅ Confirm the connection on the TV screen if required.
This method is particularly convenient because it allows you to stream content from apps that don't have their own "casts" button, as well as display game interfaces or presentations. Image quality is often higher when using Google Home, thanks to more efficient stream compression.
It's important to note that Google Home requires a Google account, which must be authorized on your smartphone. Also, make sure the Chromecast feature is enabled on your TV; on some models, it may be disabled by default in the network settings.
Streaming video via browser and DLNA
Sometimes you don't need to display the entire screen on your TV, but only a specific video file, such as a movie saved on your phone. In this case, using the protocol DLNA, which allows you to transfer media files directly to the renderer (TV).
Many modern TVs have built-in media players that support DLNA. To use this, simply open a video file on your Redmi, tap the "Share" button or the cast icon (the rectangle with waves), and select your TV. The system will automatically switch to media server mode.
☑️ Pre-broadcast check
An alternative option is to use the Google Chrome browser on your smartphone. Open the video page, click the menu (three dots), and select "Cast." This method works with almost all Smart TVs and allows you to control playback from your phone, using it as a remote.
⚠️ Please note: The DLNA protocol does not support streaming protected content from some streaming services (Netflix, Disney+) due to licensing restrictions. For these services, use the built-in "casts" button in the service's app.
Comparison of connection methods and their features
The choice of connection method depends on your specific needs and TV model. Each method has its own advantages and disadvantages, which should be considered when setting up your home entertainment system.
Below is a table to help you quickly determine the best option for your situation:
| Method | Protocol | Delay | Quality |
|---|---|---|---|
| Built-in broadcast | Miracast | Low | High (Full HD/4K) |
| Google Home | Chromecast | Average | Adaptive |
| DLNA / Media Player | DLNA | Absent | Original file |
| Chrome Browser | Cast | High | Depends on the network |
If you plan to play mobile games on a big screen, built-in streaming (Miracast) is best, as it ensures minimal input lag. DLNA is ideal for watching movies from your gallery, and Google Cast is ideal for sharing web pages.
Hidden developer settings
In the "Developer Options" menu on Redmi, you can find the "Enable Wireless Monitor" option, which activates hidden broadcast debugging features useful for advanced users.
Troubleshooting and troubleshooting
Despite the simplicity of setup, users may encounter a number of difficulties. The most common issue is the TV not detecting the phone, or vice versa. In 90% of cases, this can be resolved by ensuring the devices are on the same network.
If the devices can see each other, but the connection keeps dropping or the video is lagging, try the following:
- 🔄 Restart the router and both devices (TV and phone).
- 📶 Move closer to the router to improve the Wi-Fi signal strength.
- 🔋 Disable power saving mode on your Redmi, as it may limit Wi-Fi performance.
- 🆙 Update the application you use for streaming or your system software.
In some cases, your antivirus or router firewall may block ports required for video streaming. Try temporarily disabling traffic filtering or creating an unrestricted guest network.
Using third-party applications for complex cases
When standard tools fail, specialized applications from the Play Market come to the rescue. Programs like Cast to TV, AllCast or Web Video Caster have advanced functionality and support a wider range of video file formats.
These apps can often stream video on the fly from a browser, even if a website blocks standard streaming. They act as an intermediary, receiving the stream from the internet and sending it to the TV in a format it understands.
When using third-party software, be careful with permissions. The app will require access to your local network and files. Make sure you download programs only from trusted developers to avoid personal data leaks.
Why doesn't the TV see my Redmi?
Most often, the problem is that the devices are connected to different networks (for example, one to a guest network and one to the main network) or client isolation is enabled on the router. Also, check if multicast traffic is blocked on the router.
Is it possible to broadcast a screen if there is no internet?
Yes, if your router is sharing a local network, internet access is not required for streaming. However, for initial setup and authorization of some services, internet access may be required.
Does streaming affect battery life?
Yes, streaming video over Wi-Fi and keeping the screen on drains battery power significantly. For extended viewing, it's recommended to connect your phone to a charger.
Do all Redmi support this feature?
