Modern smart TVs make it possible to turn the living room into a real multimedia center, but it often becomes necessary to bring content directly from the smartphone. Owners of Xiaomi and Redmi equipment face this, wanting to watch photos, videos or the desktop of the device on a large screen. Fortunately, the Mi Home ecosystem offers many built-in tools to solve this problem without buying additional cables.
The streaming process can take place in different ways depending on your gadget’s operating system and your TV model. In this article, we’ll take a look at all the available methods, from the standard Wireless Display feature to using third-party apps, learn how to quickly connect devices and fix typical connection problems.
The main advantage of the technology is that there are no wires, which makes it more comfortable to use the technology. You don't have to look for adapters or pull. HDMI-It's a stable Wi-Fi network, and a few minutes of time to set up the initial setup, and then it takes seconds to output the image.
Preparation of equipment and network
Before you start setting up, you need to make sure that both devices are in the same connection conditions, which is a critical step, because the LAN is a bridge for data, and if the phone is connected to 4G mobile Internet and the TV is connected to Wi-Fi, they just don't "see" each other.
Make sure that the router supports IEEE 802.11n or higher standards to ensure high video streaming speeds. With low signal levels, picture quality may fall, delays or compression artifacts will appear. Ideally, the distance between the router and the signal receiver should not exceed reasonable limits for your router model.
It’s also worth updating your TV firmware to the latest version via the Settings menu → About TV → System Update. Developers regularly release patches that improve the stability of media file transfer protocols. Old software may contain bugs that interfere with correct pairing.
💡
Use a 5GHz network instead of 2.4GHz if your router supports dual-band operation – this will significantly reduce latency when streaming high-resolution video.
Use of the built-in Wireless Display function
The most common method, which works on most Redmi and Mi TV models, is based on Miracast technology, which allows you to duplicate the screen of the smartphone completely, which is convenient for showing presentations or games, and the corresponding signal receiver must be activated on the TV.
To do this, click the signal source select button (often denoted as Input or the arrow square icon) and select Wireless Display or Wireless Display. The screen will display a wait for the connection with your TV name. Now we move on to the phone setup.
On an Android smartphone, open the notification curtain and find the Translation, Projection or Smart View feature (name depends on the manufacturer). After scanning the networks, your Xiaomi TV should appear in the list. Click on it to begin pairing.
☑️ The Wireless Display Connection Algorithm
Consider that when you connect, your phone screen may not go out, consuming battery life. Some phone models allow you to change the resolution of the output image to save resources. If you see a message that you do not support, it is possible that the Wi-Fi Direct driver on your device is not working properly.
⚠️ Note: Wireless Display may not work properly if client isolation is enabled on the router (AP Isolation, which prevents devices on the same network from sharing data with each other.
Broadcasting through Chromecast built-in
Many modern Xiaomi TVs run on Android TV or have built-in support for Google Cast technology. This allows you to stream content from specific applications (YouTube, Netflix, Chrome browser) without duplication of the entire screen of the smartphone.
Make sure your phone has Google Home or the appropriate Google Play services installed. Open an app that supports live streaming (like YouTube) and click on the box icon with the waves in the corner. Select your Mi TV from the list of available devices.
The advantage of this method is that you can use the phone for other tasks while the video is played on the big screen, and the TV acts as a standalone client, getting data directly from the Internet, rather than through a smartphone, which reduces the load on the battery of the mobile device.
| Characteristics | Wireless Display | Chromecast Built-in |
|---|---|---|
| Type of transmission | Screen duplication | Streaming |
| Dependence on the phone | High (screen active) | Low (can be rolled) |
| Video quality | Depends on the power of the phone. | Maximum (up to 4K HDR) |
| Battery consumption | High-pitched | Low. |
Why is 4K video slowing down?
Streaming from iPhone (iOS) to Xiaomi TV
Apple owners will need AirPlay technology, which is supported by many Xiaomi models. If your TV does not have native support for AirPlay 2, you can install the AirScreen app or the analogue from the Google Play store on the TV itself, which will turn the Android box into a signal receiver from the iPhone.
Once you install the app on your TV, run it and wait for the code or device name to appear. On your iPhone, open Control Point (swipe down from the top right corner or bottom up depending on the model) and click Screen Replay. Select your Xiaomi TV from the list.
It is important to note that AirPlay requires good network bandwidth to work smoothly. If you use a third-party emulator app on TV, make sure it has the necessary permissions on Android TV. Sometimes you need to manually allow access to a microphone or storage to properly operate the audio track.
If the picture appears but no sound, check the audio output settings in the emulator app itself on the TV. Often by default, the sound can go through the phone's speaker. Switch the output to HDMI or the system audio output in the app's settings on TV.
Connection problems and their solution
The most common problem is that the TV is not on the list of available devices, in which case you should try to reboot the router, because the network spreadsheet cache may have overflowed, and switching Wi-Fi bands also helps: if the devices are at 5 GHz, try 2.4 GHz, and vice versa.
Another reason could be the timing of the date, and if the TV and the phone have very different system time, security protocols can block the connection, and make sure that both devices automatically synchronize time over the network.
💡
90% of connection problems are solved by simply restarting the router and checking that both devices are on the same subnet (the same is true). IP-lock-house).
If you're using an antivirus or firewall on a router, try temporarily disabling packet filtering. Some smart traffic protection features may view broadcast requests from your TV as a threat and block them.
⚠️ Note: Do not use the guest Wi-Fi network to connect smart home equipment, as in this segment of the network, data exchange between devices is usually prohibited by router settings.
Use of the HDMI-cable as an alternative
When wireless connectivity is unstable or requires maximum quality without compression, consider a wired connection, such as a USB-C to HDMI adapter (for modern smartphones) or a Lightning to HDMI adapter (for iPhones), and the TV acts as a monitor.
Connect the adapter to the phone, then connect it with an HDMI cable to the TV, switch the signal source to the TV to the appropriate port (for example, HDMI 1). The image should appear automatically, although some phone models need to allow data transfer in the request that appears.
This method is ideal for gaming, as input lag is minimal, but it is debilitating because the phone is tethered to the TV by a cable, and it is worth considering that not all budget smartphone models support video output via the charging port.
Does my phone support video output?
Setting up image and sound parameters
Once you've successfully connected, it makes sense to adjust the output settings for better visuals. From the TV menu, go to the image settings and select Movie or Game mode depending on the content, which will improve color reproduction and contrast.
Note the aspect ratio. When broadcasting from your phone to the horizontal screen, there may be black bars on the sides, and you can change the zoom settings (the option “Just Scan”, “Screen Fit” or “Size of screen”) to remove the extra fields.
For sound, it is recommended to use external acoustics or soundbar if the TV's built-in speakers fail, you can connect them via optical output or Bluetooth if the TV model supports the transmission of sound to external devices, which will create a more immersive effect when watching movies.
