Modern Xiaomi, Redmi and Poco smartphones have powerful screens, but 6 inches of diagonal is often not enough to watch movies or photos with the whole family. Fortunately, Miracast technology and built-in MIUI features allow you to instantly duplicate an image on a large Smart TV screen. This is convenient not only for multimedia, but also for presentations or mobile games.
The connection process can vary depending on your TV model and the version of the Android operating system. There are both wireless methods that work over Wi-Fi and wired options that ensure maximum signal stability. In this article, we will discuss all the current ways that will help you enjoy content on the big screen without complex settings.
Before you start, make sure that both devices are compatible and in good working order. Usually, the process takes no more than a couple of minutes if the basic network requirements are met, and let's look at exactly how this data magic works.
Basic requirements and equipment preparation
There are several prerequisites to successfully synchronize your gadget and TV: the most important is having a Smart TV or a regular set-top box that supports Android TV. If your TV is old and doesn’t have “intelligence”, you will need an additional adapter.
Both devices must be connected to the same Wi-Fi network. This is a critical point, since the data protocols do not work through different routers or the mobile Internet. Make sure that the signal is stable, otherwise the video may be interrupted.
It’s also worth updating your smartphone software to the latest available version. Xiaomi often comes up with patches that improve wireless modules. Make sure that the Wi-Fi Display feature is activated in the system settings.
⚠️ Note: When using a guest Wi-Fi network in hotels or offices, the broadcast may be blocked by the network administrator due to restrictions on local traffic exchange between devices.
Don’t forget to check the battery charge of your smartphone, as active video streaming consumes a lot of energy.It is better to keep the device connected to charging during long browsing sessions.
Translation method through the built-in function "Translation"
The easiest and fastest way to do this without having to install third-party apps is to use a native feature, which is called "Translation" or "Cast" in the MIUI or HyperOS shell, which is based on the Miracast standard that most TVs today support.
To start, lower the notification curtain down and find the Translation icon. If it's not on the first screen, press the panel edit button (usually three dots or a pencil) and drag the icon to the active zone. Once you press it, the phone will start searching for available devices within network range.
When the name of your TV appears on the screen, select it; the TV screen may have a request for confirmation of connection, which must be coordinated by the remote control, and then the image from the phone is fully duplicated on the large screen.
- 📺 Open the control panel and find the "Translation" icon".
- 📶 Make sure that Wi-Fi is on both devices.
- 🔗 Select your TV from the list of found devices.
- ✅ Confirm the connection on the TV screen if required.
If the search is not working, you may not have the signal reception function on the TV. Go to the TV settings and find the Screen, Screen Share or Miracast section and turn it on manually.
☑️ Checking before connection
Using the Google Home app for Android TV
If your TV is running Android TV or has Chromecast support built in, the standard Translation feature may not work properly or detect the device, in which case the official Google Home app comes to the rescue.
Download and install the app from the Google Play Store. Once logged in through your Google account, the program will automatically scan the network and find connected smart devices, including TVs and speakers. This is a more robust method for the Google ecosystem.
In the main menu of the app, find your TV card. Click on it to open the control menu. At the bottom of the screen, you'll see a "Cast my screen" button. Press it and the system will warn you that audio and video will be transmitted to the TV.
This method is particularly good because it allows you to broadcast not only video, but also the interface of games or applications that block standard image transmission, in which case the delay is minimal if the router supports a frequency of 5 GHz.
⚠️ Note: When streaming via Google Home, audio from your phone may not be transmitted to your TV in some apps due to restrictions DRM-contention.
To stop the broadcast, it is enough to click on the icon in the application again or unlock the smartphone screen and click on the pop-up notification.
What if Google Home doesn’t see TV?
Broadcasting videos from YouTube and online cinemas
The most popular use case is running videos from YouTube, Netflix or IVi. It uses DLNA technology or proprietary casting protocols, which allow the TV to download the video stream itself while the phone acts only as a remote control.
Open an app, like YouTube on your smartphone. In the upper right corner of the video or in the player interface, find the characteristic wave rectangle, the broadcast icon. Click on it.
Select your TV from the list. The video will run on a big screen, and the phone will have control buttons: pause, rewind and volume control, and the main advantage of this method is that you can turn off the app or even turn off the phone screen, and playback will not interrupt.
The quality of the video will depend on the speed of the Internet, as the TV downloads data directly, which frees the Wi-Fi channel from transmitting heavy video stream from the phone, which reduces battery load and reduces the heating of the device.
- 🎬 Run the video in the application (YouTube, Kinopoisk, etc.).
- 📡 Click on the icon "Translation" (rectangle with Wi-Fi).
- 📺 Select the target device from the proposed list.
- ▶️ Control playback from your smartphone.
If the icon doesn't appear, check to see if you're logged in to the app on your phone and TV under the same account, a security requirement for some services.
💡
For maximum 4K HDR quality, make sure your router supports Wi-Fi 5 (ac) or Wi-Fi 6 (ax) standards, and your TV is connected to a 5GHz network, as 2.4GHz may not pull a high bitrate.
Wired connection via USB-C to HDMI
Wireless technology is convenient, but it doesn't guarantee 100% stability and often has an input lag, which is critical for gaming. For perfect picture quality and no delays, it's better to use a wired connection.
To do this, you’ll need a dedicated USB-C to HDMI adapter. It’s important to understand that the USB-C port on your smartphone must support the MHL or DisplayPort Alt Mode standard. Budget Redmi or Poco models often lack this feature, transferring only data and charge, but not video.
Connect the adapter to the smartphone, and insert it into it HDMI-Switch the TV to external signal sources (Source button or Input button on the remote) and select the appropriate port. HDMI.
The image should appear automatically. If it doesn't, go to the phone settings: Settings → Connections and Sharing → Advanced settings. You may need to manually select permission or output mode.
| Type of connection | Delay (Latency) | Quality. | Battery consumption |
|---|---|---|---|
| Wi-Fi (Miracast) | Tall. | Good. | Medium. |
| Google Cast | Medium | Excellent. | Low. |
| USB-C to HDMI | Absent. | Perfect. | Charging is coming. |
When wired, the phone will usually start charging from the TV or require separate power, as video transmission consumes a lot of power.
💡
Wired connectivity is the only way to play dynamic shooters or simulators on a TV without control delays, but it requires video output support from a smartphone.
Solving Connection Problems and Errors
Even if you follow all the instructions, you can have technical failures, and a common problem is that you can't see the TV on the list of available devices, and 90 percent of the time, you can just reboot the router because you can have errors in the table. ARP-address.
Another common situation is to de-synchronize sound and video, and if the actors' lips don't fit the words, try to find "Sound Lag" or "Audio Delay" in your TV settings and adjust it, and switching Wi-Fi from 2.4 GHz to 5 GHz also helps.
If you have an image but it's not on the whole screen (black bars on the edges), check the aspect ratio settings. On the TV, it's the Aspect Ratio or P.Size button on the remote, and on the phone, you can sometimes select Full Screen mode in the broadcast menu.
⚠️ Attention: Some content-protected applications (banking, paid subscriptions) may display black screens instead of videos when attempting to stream, a normal protection against piracy that cannot be circumvented legally.
If you have a connection break, try to forget your phone’s Wi-Fi network and reconnect it, and make sure that the router doesn’t have a limit on the number of connected devices or the speed for each client.
