How to Duplicate Your Phone Screen on a Xiaomi TV: A Step-by-Step Guide

Dubbing a smartphone screen on a Xiaomi TV opens up new possibilities for viewing content, games and presentations. Whether itโ€™s wireless Wi-Fi or wired HDMI, modern Xiaomi TVs support several synchronization methods. However, not all methods are equally effective: some provide minimal latency for games, others are optimal for high-resolution video.

In this article, we will discuss all the current ways to duplicate the screen on Xiaomi TVs (including models with Android TV and MIUI TV), their advantages and limitations. You will learn how to set up a connection on Xiaomi, Redmi and POCO phones, as well as what problems can arise when connecting and how to solve them.

Preparation of TV and telephone for duplication

Before you start setting up, make sure both devices meet the minimum requirements. Xiaomi Android TVs (Mi TV A, Mi TV Q, Redmi Smart TV series) support all modern broadcast protocols, whereas models with MIUI TV (such as Mi TV 4S) may have restrictions.

  • ๐Ÿ“ฑ Android 8.0 or later (for Miracast)
  • ๐Ÿ”„ Wi-Fi Direct or Miracast support
  • ๐Ÿ”‹ Battery charge of at least 30% (for stable operation)
  • ๐Ÿ“ถ Same Wi-Fi network for phone and TV (when using Google Cast)

To check compatibility on your TV, go to Settings โ†’ Connections โ†’ Screen Mirror. If you donโ€™t have an option, update your TV firmware through Settings โ†’ About TV โ†’ System Update. On your smartphone, activate Developer Mode and enable USB Debugging (for wired methods) or check for Wireless Display in Quick Settings.

If your Xiaomi TV doesnโ€™t find the phone when trying to connect, try restarting both devices and temporarily disabling the VPN on your smartphone โ€“ this often solves detection problems.

Wireless Duplication via Miracast (without the Internet)

Miracast allows you to broadcast the screen without connecting to the router, creating a direct connection between devices.This method is suitable for presentations or viewing local files, but can give a delay of up to 100 ms. TV:

  1. On TV: Settings โ†’ Devices and accessories โ†’ Screen mirroring โ†’ select Miracast.
  2. On your phone: lower the notification curtain โ†’ press Wireless Display (or Screen Cast in MIUI 14+).
  3. In the list of available devices, select the name of your TV (e.g. MiTV-AB1234).
  4. Confirm the connection on the TV if you receive a request.

For models with MIUI TV (e.g. Mi TV 4A), the path may be different: Settings โ†’ Network โ†’ Miracast. If the image slows down, reduce the resolution of the broadcast in the Miracast settings on the phone or activate Game Turbo mode on TV to reduce latency.

Make sure you have Miracast | on TV.

3. Broadcast via Google Cast (Chromecast)

Xiaomi Android TVs have built-in support for Google Cast, allowing you to duplicate the screen or stream individual apps (YouTube, Netflix), a method that requires both devices to connect to the same Wi-Fi network.

1. On your TV, open the Google Home app (preinstalled on Android TV) or go to Settings โ†’ Devices and Accessories โ†’ Screen Transfer.

2. On the phone in quick settings, select Transfer (or Smart View on some MIUI firmware).

3. In the list of devices, select your TV (the name will contain a model, for example, MiTV-Q1-55).

4. Confirm the connection on TV, if necessary.

To broadcast only sound (such as music), use the option to transmit sound in the same settings. Please note: some applications (such as Disney)+) They may be blocking the broadcast because of DRM-defense.

  • ๐Ÿ”Œ Adapter with DisplayPort Alt Mode (e.g. Xiaomi) USB-C to HDMI)
  • ๐Ÿ“บ HDMI-2.0 cable or later
  • โšก Power supply for adapter (some models require additional power supply) USB-feed-in)

Instructions:

  1. Connect the adapter to the USB-C port of the phone.

  3. On the phone, select External Display mode in the screen settings (path: Settings โ†’ Display โ†’ Output mode).
  4. On TV, select the appropriate signal source (e.g. HDMI 1).

For POCO F5 or Redmi Note 12 Pro+ models with DisplayPort 1.4 support, 1440p@120Hz resolution is available, but the TV must support this refresh rate.

Why is the image not transmitted over HDMI?
If the phone screen is not duplicated, check: 1) Does your Alt Mode adapter support (cheap Chinese adapters often don't work). 2 Is there enough power - some adapters require a charging connection. 3 Is USB Debugging Mode enabled (sometimes required for proper operation). 4 Are the permissions compatible - try manually setting 1080p@60Hz in the phone display settings.
