Modern smartphones Xiaomi Redmi They offer powerful multimedia capabilities that allow you to transform your device's screen into a home theater control center. Owners often wonder how to display content on a larger screen to enjoy movies, photos, or games without the limitations of a small display. Wireless connection technology via a local network Wi-Fi is the most convenient and popular solution that does not require the purchase of additional cables or adapters.
The process of synchronizing the gadget with Smart TV based on standard data transfer protocols such as Miracast, DLNA, or built-in Google Chromecast functions. In the operating system MIUIThese tools are already integrated by default on Redmi smartphones, making the process much easier for the user. However, there are some nuances that depend on the specific TV model and phone firmware version that must be taken into account for stable operation.
This guide details all available connection methods, from standard system functions to specialized apps. We'll address common issues users encounter when trying to establish a connection and offer effective solutions. Proper network configuration and an understanding of broadcast protocols will ensure high-quality video and a smooth experience.
⚠️ Note: The MIUI menu interface may vary slightly depending on the Android version and regional ROM of your Redmi. The layout of the options may vary, but the logic remains the same.
Preparation of equipment and network infrastructure
The first and most critical condition for a successful connection is that all devices are in a single information space. Your smartphone Redmi The device and TV must be connected to the same Wi-Fi network. If you have a dual-band router, make sure both devices operate on the same frequency, although modern routers usually handle traffic correctly between the 2.4 GHz and 5 GHz bands.
The quality of the wireless signal directly impacts the stability of the stream. High-resolution video streaming, especially 4K, requires high bandwidth. It is recommended to move closer to the router during the initial pairing process to avoid packet loss due to a weak signal.
- 📡 Make sure the function is activated on your TV Smart TV and it is connected to the internet.
- 📱 Check that the Wi-Fi module is enabled on your Redmi and that the name of your home network is displayed.
- 🔌 Restart your router if the connection seems unstable or devices cannot see each other.
- 🔋 Charge your smartphone to at least 20%, as active video streaming quickly drains battery power.
In some cases, antivirus software or router firewall settings may block local communication between devices. If you use advanced network security settings, temporarily relax them to test the hypothesis that ports required for protocols are being blocked. DLNA or Miracast.
Using the built-in "Cast" feature in MIUI
The easiest way, which doesn't require installing any third-party software, is to use the system utility "Broadcast". In the shell MIUI This tool is often hidden in the "Tools" folder or placed in the control menu (notification shade). The function is based on the standard Miracast, which allows you to mirror your smartphone screen to your TV in real time.
To start the process, open the control panel by swiping down from the top and finding the "Cast" icon. If the icon isn't available in the quick access menu, open the Settings app, go to "Connection and Sharing," and select "Cast." The system will automatically search for available devices on your local network.
Settings -> Connection and Sharing -> BroadcastOnce your TV is listed, tap its name. A connection confirmation prompt may appear on the TV screen, which you'll need to accept using the remote. From this point on, the Redmi TV's full screen image will be mirrored to the big screen, including system notifications and audio.
⚠️ Note: When using the "Cast" feature, your smartphone's screen may dim to save power, but the video stream will continue. If the screen dims and the stream is interrupted, check the screen timeout settings in the "Screen & Brightness" section.
☑️ Pre-broadcast check
Streaming via Google Home and Chromecast
Many modern TVs have built-in support for this technology. Chromecast, developed by Google. Even if your TV doesn't have built-in Chromecast, this feature can be added via an external set-top box. Redmi smartphones have deeply integrated Google services, making this method one of the most stable.
To implement this method you will need an application Google Home, which is often preinstalled or available in the Play Market. After installing and logging in, the app will scan the network and find compatible devices. Select your TV from the list and click the "Cast Screen" button.
The advantage of this method is the ability to control the stream from other devices and more advanced video buffering. Unlike Miracast, it uses Google's server side, which sometimes allows for streaming even on less-than-ideal local network conditions, although direct mode (P2P) is still preferable.
What to do if Google Home doesn't see the TV?
Make sure discovery is enabled on your TV in the network settings. Also, make sure location services are enabled in the Google Home app on your smartphone, as this is required on Android to scan for nearby Bluetooth and Wi-Fi devices.
Streaming videos and photos via DLNA
Protocol DLNA (Digital Living Network Alliance) isn't designed for full screen mirroring, but for streaming media content such as videos, photos, and music. It's ideal if you want to watch a downloaded movie in high quality without draining your battery on interface rendering.
Most modern TVs have a built-in media player with DLNA support. On the Redmi, you can use the standard gallery or video player. Mi VideoAfter opening the video file, find the "Broadcast" icon (a rectangle with waves) and select your TV. The file will begin playing on the TV, and you can use your phone as a remote control.
For more advanced users, it is recommended to use third-party players such as VLC for Android or MX PlayerThey have more powerful codecs and handle heavy video formats like MKV or AVI with high bitrates better. In the playback menu, select "Renderer" or "Cast" and specify the target device.
| Method | Image quality | Latency | Battery consumption |
|---|---|---|---|
| Miracast (Broadcast) | High (depending on signal) | Low (important for gaming) | High |
| Chromecast | Stable HD/4K | Average | Average |
| DLNA | Original (uncompressed) | Absent (streaming) | Short |
| HDMI cable | Maximum | Zero | Charging (usually) |
Troubleshooting connection and latency issues
Despite the simplicity of the technology, users may encounter issues where the TV doesn't appear in the list of available devices or the connection constantly drops. Most often, this is due to router settings that isolate devices from each other. Check that the "AP Isolation" feature is not enabled in your wireless network settings.
Another common issue is audio and video desynchronization. This often occurs when neighboring networks are congesting the Wi-Fi channel. In this case, it's a good idea to manually change the Wi-Fi channel in your router settings to a less congested one, such as 1, 6, or 11 in the 2.4 GHz band, or switch to 5 GHz if your router and TV support it.
If Redmi's built-in methods don't work, try updating your TV's software. TV manufacturers regularly release patches that improve compatibility with new versions of Android and security protocols. WPA3You should also try resetting your smartphone's network settings by deleting the saved Wi-Fi profile and reconnecting.
⚠️ Note: If you're using a guest Wi-Fi network, devices may not be able to see each other for security reasons. Be sure to use your main home network for streaming.
Alternative applications for specific tasks
In cases where standard means MIUI don't provide the required functionality, specialized applications from the Play Market come to the rescue. For example, the application Tv Cast or Web Video Caster Allows you to stream video from browsers that don't have a "Cast" button. This is especially useful for watching online movies from sites that don't support live streaming.
For gamers who want to get the game on the big screen with minimal lag, there are apps like GameStream or Steam Link, if the corresponding server is running on the TV or connected PC. However, for simple games, the standard "Broadcast" function is also suitable, although input lag will always be present to some degree in wireless mode.
If your old methods stop working after installing a new app, check your app permissions in Android settings. Access to your local network and microphone (for voice search) should be allowed.
Why doesn't the TV detect Redmi when streaming is enabled?
Most often, the problem is that the devices are on different subnets or client isolation is enabled on the router. Also, make sure that Screen Sharing or a similar app is running on the TV and waiting for a connection.
Is it possible to stream your screen to a regular TV without a Smart TV?
Yes, this will require you to purchase an HDMI adapter with Wi-Fi support (such as an AnyCast or Miracast dongle), which plugs into your TV's HDMI port and creates an access point for your Redmi.
Does broadcasting affect internet speed?
When using DLNA and Chromecast, traffic flows within the local network and doesn't consume internet bandwidth. Using Miracast also eliminates internet usage, as it creates a direct Wi-Fi Direct connection between the phone and TV.
How to reduce audio lag when watching videos?
Try lowering the video quality in the source app or restarting your router. Some players have an audio sync setting that allows you to manually shift the audio track.
Is it safe to use third-party streaming apps?
Use only verified apps with high ratings on the Play Market. Avoid programs that require suspicious permissions, as they access your local network.
