Modern Xiaomi and Redmi TVs have a powerful Android TV platform that turns a conventional display device into a full-fledged multimedia center. However, for comfortable viewing of content from a mobile device, it often becomes necessary to synchronize the smartphone and the large screen. Wireless connection allows you to instantly show photos, videos or even gameplay without limiting the user to wires.
The setup process can vary depending on your phone’s operating system, whether it’s Android or iOS. It’s important to understand that for mirroring to work properly, both devices must be on a single LAN. The critical condition is to use the same Wi-Fi network for your TV and smartphone, as different frequencies (2.4 GHz and 5 GHz) can block device detection.
In this article, we will take a detailed look at all the available connectivity methods, from standard system functions to specialized applications, and learn how to eliminate common errors and customize settings to minimize data latency.
Preparing devices for synchronization
Before you start the active setup phase, you need to make sure that the equipment is ready to interact. Often users are faced with the fact that the TV does not see the phone, and the reason lies in the basic network settings. Check that your router is sending a signal consistently, and both gadgets are connected to it, and not to the mobile Internet.
On a Xiaomi TV, you should check the operating system version. Go to Settings → About TV → Version. If system updates are available, they should be installed, as new patches often contain patches for Miracast and Chromecast protocols.
- 📱 Make sure that the smartphone is enabled Wi-Fi and Bluetooth module.
- 📺 Check that the TV is connected to the same Wi-Fi network as the phone.
- 🔄 Restart router if connection is unstable or breaks are observed.
Sometimes antivirus programs on your phone or firewall settings on your router can block local device detection, which requires you to temporarily relax protection or add devices to the trusted list.
☑️ Checking before connection
Use of the built-in Chromecast feature
Google Cast (Chromecast built-in) technology is native to the Android TV operating system installed on Xiaomi TVs.It is the most convenient way to stream content from apps such as YouTube, Netflix or online cinemas directly to the big screen without loading on the smartphone processor.
To activate the function, open the app with video content on your phone. In the player interface, find the icon of the rectangle with waves in the corner, which is a standard broadcast symbol. When you click on it, you will see a list of available devices on your network.
If the list is empty, check the permissions for the Google Home app. It must have access to geolocation and local area network, otherwise the device search will not work. Also make sure that the Chromecast system component is activated on the TV in the Apps → My apps section.
⚠️ Note: When using Chromecast, video is transmitted directly by the TV from the internet, so download speed depends on the quality of your Wi-Fi connection, not the speed of the phone.
In some cases, manual activation of the receiver is required. Go to the settings of the TV, select Settings → Applications → System applications → Chromecast built-in and make sure the function is not disabled. Once you select the device in the list, the connection will begin on the phone.
💡
If the livestream icon doesn’t appear in the YouTube app, try updating the Google Play Services app on your smartphone to the latest version.
Streaming Android screen via Miracast
Unlike the Chromecast, which broadcasts specific content, Miracast technology allows you to completely duplicate the screen of your smartphone on your Xiaomi TV.
On Xiaomi TVs, this feature can be called variously: “Wireless Display”, “Translation” or “Screen Mirroring”. To start a search, open the signal source menu (button with the image of a square with an arrow on the remote) or find the corresponding application in the menu.
On Android, the algorithm of actions is as follows:
1. Open the notification curtain and look for Broadcast, Smart View or Projection (name depends on the brand of the phone).
2. Click on the search for the devices.
3. Select your Xiaomi TV from the list.
After confirming the connection on the TV screen will appear an exact copy of the image from the phone. that in this mode the phone is not locked, and all notifications will be visible on the large screen.
Why is there a delay in the image?
Connection of iPhone and iPad (AirPlay 2)
Apple owners can use the AirPlay 2 protocol, which is officially supported by modern Xiaomi TVs, which ensures high quality image and sound with minimal latency.
To get started, make sure your TV has AirPlay enabled. It's usually active by default, but check this out in Settings → AirPlay. If the feature is off, activate it.
On your iPhone or iPad, do the following:
1. Open the "Control Point" (swipe down from the upper right corner or up from the bottom).
2. Press the screen repeat button (two intersecting rectangles).
3. Select a Xiaomi TV from the list offered.
When you first connect to your TV, you may have a four-digit code that you need to enter on your iPhone, and after successful authorization, the screen will be fully projected onto the TV.
| Parameter | Android (Miracast) | iOS (AirPlay 2) | Chromecast |
|---|---|---|---|
| Type of transmission | Screen mirroring | Screen mirroring | Streaming transmission |
| Dependence on the phone | High (screen on fire) | High (screen on fire) | Low (can be rolled) |
| Sound quality | Standard. | High. | High. |
| Delay. | Low. | Minimum |
Wired connection via HDMI
If the wireless connection is unstable or requires maximum image quality without compression, the best solution is a cable connection. To do this, your smartphone must support video output via a USB-C port (MHL technology or DisplayPort Alt Mode).
You will need a special USB-C to HDMI adapter, connect the narrow end of the adapter to the phone, and connect the standard HDMI cable to the adapter and TV, switch the signal source to the TV to the appropriate port (for example, HDMI 1).
Unlike wireless methods, you don't need to set up the network; the image will appear automatically as soon as the phone recognizes the external display; and in the phone settings (Screen section), you can choose to work: mirror or desktop extension (if supported).
⚠️ Note: Not all smartphones support video output via USB-C. Budget models often lack this feature and the adapter won't work. check your model specification before buying the cable.
The advantage of this method is that it doesn't have latency, which is critical for mobile gaming, and you can often charge your phone at the same time with a power cable.
💡
HDMI wired connectivity guarantees the best picture quality and no delays, but requires a compatible smartphone and the purchase of an additional adapter.
Solving and eliminating errors
Even with the right setup, there can be technical failures. If the TV stops seeing the phone, try to completely reboot both devices by turning them off the socket on the phone. 10-15 This will clear the cache of the network modules.
A common problem is to desynchronize sound and image. This is treated in the settings of the TV: go to Settings. → Sound. → Synchronization of sound HDMI/AV and move the slider until it matches.
If the connection is interrupted on its own, the router may be overloaded. Try switching the TV to 5GHz if it supports dual-band Wi-Fi, as it is less noisy than the standard 2.4GHz.
- 🔌 Check the density of the fittings. HDMI cable, if you use a wired connection.
- 📶 Make sure the distance between the router and the TV is not too large.
- 🛡️ Turn it off. VPN on the phone, as it can interfere with local device search.
In rare cases, resetting network settings on the TV to factory values helps, but this will require re-entering the password from Wi-Fi.
