Introduction: Why to transfer video to the big screen
Modern Xiaomi TVs (Mi TV, Redmi Smart TV, Xiaomi TV A) are equipped with powerful processors and support for 4K HDR, but their potential is only revealed when connected correctly. Transferring video from phone to big screen allows you to enjoy content without loss of quality โ whether it is home recording, streaming services or games. However, not all users know that Xiaomi TVs based on Android TV support up to 5 different wireless transmission protocols, and the choice of method depends on the smartphone model and firmware version.
In this article, weโll look at all the current ways, from standard Miracast to Xiaomi proprietary technologies such as Mi Share and Quick Apps. Particular attention will be paid to solutions for iPhone (where compatibility problems often arise) and older TV models (for example, the 2018 Mi TV 4A), where workarounds may be necessary. If you have previously encountered image delays or connection breaks, here you will find reasons and ways to fix them.
1. Wireless transmission via Miracast (Screen Mirroring)
Miracast is the universal standard for wireless screen duplication supported by most Xiaomi TVs (starting with Mi TV 3) and works on a point-to-point basis, without requiring a single Wi-Fi network, making it reliable even in a weak Internet connection. However, there are nuances: the iPhone Miracast is not natively supported (third-party software will be required), and on Android smartphones the function can be called differently depending on the manufacturer.
To activate Miracast on Xiaomi TV:
- Open Settings โ Connection and Sharing โ Wireless projection.
- Select Miracast (or Screen Mirroring on English firmware).
- On your smartphone, enable screen duplication (on Xiaomi/Redmi โ Settings โ Connections and Sharing โ Transfer to the screen).
- Select your TV from the list of available devices.
Important: The first connection may be a request for a password confirmation (usually 0000 or 1234).If the image is slowing down, try reducing the screen resolution of your smartphone to 1080p in the Miracast settings.
Problems and solutions for using Miracast
- ๐ Sound/image delay: Turn off Bluetooth devices (earphones, gamepads) โ they can cause interference. Also check if the TV is not on Game mode (it increases the delay for processing video).
- ๐ซ TV not detected: Restart router - sometimes Wi-Fi channels conflict. On TV, try changing network mode from 5 GHz to 2.4 GHz (or vice versa).
- ๐ต Connection breaks: Make sure your smartphone has power saving disabled for Screen Mirroring (on Xiaomi, this is done in Settings). โ Battery โ Optimizing the battery).
โ ๏ธ Note: On Xiaomi TVs with firmware older MIUI TV 3.0 (released before 2020) may not support Miracast in 5 GHz mode. in this case, force the TV to switch to 2.4 GHz through the Wi-Fi menu.
2. Transmission via DLNA (media server)
DLNA allows you to stream video files directly from your phone to your TV without having to duplicate the entire screen, which is convenient for watching movies, photos or music, but not suitable for games and applications. Unlike Miracast, it doesn't require high connection speeds โ fairly stable Wi-Fi.
Instructions for Android:
- Install a media server application, such as BubbleUPnP or LocalCast.
- On Xiaomi TV, open the Media Player app (or Gallery on new models).
- In the Network or DLNA section, select your smartphone from the list of devices.
- Select the file to play back.
For the iPhone, the algorithm is different:
- ๐ฑ Install the app VLC for Mobile or nPlayer.
- ๐ In the application settings, activate DLNA/UPnP Renderer.
- ๐บ On the TV in Media Player, find your iPhone on the local network.
Smartphone and TV connected to the same Wi-Fi network
