Outputting your smartphone image on a big screen on Xiaomi TV opens up new possibilities, from watching high-resolution movies to showing presentations or streaming games. However, not everyone knows that there are excellent duplication methods for different TV and phone models, from built-in Miracast features to using third-party adapters. In this article, we will analyze all the current methods, including hidden settings that the manufacturer does not advertise.
Xiaomi TVs (Mi TV A2, P1, Q2, etc.) have several wireless protocols, but not all of them work equally stable. For example, signal latency when playing through Google Cast can reach 150 ms, while Miracast only gives 60-80 ms. We tested each method in practice and collected data in the comparative table below.
1. Wireless output via Miracast (built-in function)
Miracast is a wireless screen transfer standard that supports all modern Xiaomi TVs (starting with 2018 Mi TV 4) and Android 5.0+ smartphones. The main advantage is the lack of need for the Internet: communication is established directly between devices via Wi-Fi Direct.
To activate duplication:
- 📱 On the phone: open Settings → Connections → Screen transmission (on Xiaomi/Redmi It can be called a Wireless Display or Cast).
- 📺 On TV: Go to Settings → Connection and sharing → Wireless display and enable the option.
- 🔍 The list of available devices on your phone will show the name of your TV (for example, the name of your TV, MiTV-P1-1234). Choose him.
💡
If the TV doesn’t appear in the list, try rebooting the router – sometimes background connections of other devices interfere.
It is important to take into account the limitations:
- ⚠️ The screen resolution will be automatically lowered to 1080p, Even if the TV supports 4K.
- ⚠️ Sound is transmitted only when using Android 10+. On the iPhone, this method does not work.
2.Use of Google Cast (Chromecast built-in)
Xiaomi TVs on the Google TV platform (such as Mi TV Q2 2023) have built-in support for Google Cast, a technology similar to the Chromecast.It allows you not only to duplicate the screen, but also to stream content from applications (YouTube, Netflix, Twitch) directly to TV without transferring the entire interface of the phone.
Instructions:
- Make sure your phone and TV are connected to the same Wi-Fi network.
- On your phone, open an app that supports Cast (like YouTube) and tap on the broadcast icon (📡).
- In the list, select your Xiaomi TV (the name will contain a model, such as the MiTV-Q2-55).
To duplicate the screen (not just content from apps):
- 📱 On Android: Settings → Connected devices → Screen transmission → Settings (⚙️) → Enable the wireless display.
- 🍎 On iPhone: Use the Google Home app (Devices section) → Hand over the screen).
3. a wired connection through HDMI-adapter
If wireless methods are late or unstable, wired connectivity via an adapter is the most reliable option.
- 🔌 adapter USB-C/Lightning → HDMI (for Android or iPhone respectively).
- 📺 Cable HDMI 2.0 (support 4K@60Hz).
Step-by-step:
- Connect the adapter to your phone and the HDMI cable to the HDMI IN port on your TV (it’s better to use an ARC or HDMI 2.0 port).
- On the Xiaomi remote, select the appropriate signal source (SOURCE or INPUT button).
- The phone may need to confirm trust in the connected device (on the iPhone will appear notification).
Check the adapter compatibility with the phone model
Use the original HDMI cable
Enable the "Do not interrupt transmission" mode in the phone settings
Disable power saving for USB-C port (on Android)
-->
Critical detail: adapters on the MHL chip (obsolete models) do not support the Xiaomi Mi 11/12/13 and the new Redmi Note. Use only adapters with DisplayPort Alt Mode support (for example, the official one from Xiaomi or Anker).
4.Duplicate through third-party applications
If the built-in features don't work, you can use third-party apps.
- 🎮 ApowerMirror – supports low latency game mode (suitable for PUBG Mobile or Call of Duty).
- 📺 TeamViewer QuickSupport – allows you to control your phone from the remote (useful for presentations).
- 🔄 Screen Mirroring (by Google) – Miracast alternative for older TV models.
Example of ApowerMirror configuration:
- Install the app on your phone and TV (via Google Play on Xiaomi TV).
- Run ApowerMirror on both devices and select Phone Screen Mirroring mode.
- Connect to a single Wi-Fi network or use your phone’s Hotspot.
- On the phone, tap START NOW and confirm the screen recording permission.

5. Features for iPhone (AirPlay on Xiaomi TV)
Xiaomi TVs on Google TV (Models 2022 and newer) support AirPlay, Apple's protocol for wireless screen transfer.
- ✅ It only works on iPhone. 6s and newer (with iOS 12)+).
- ❌ Does not support screen duplication in applications with DRM (For example, Netflix or Disney+).
- ⚠️ Maximum authorization — 1080p, Even if the TV supports 4K.
How to connect:
- On TV: Settings → Apple AirPlay → Enable AirPlay.
- On iPhone: swipe down to open Control Point → Screen Duplication → select your Xiaomi TV.
💡
AirPlay on Xiaomi TV only works when you connect your phone and TV to the same Wi-Fi network. Mobile Internet (4G/5G) is not supported.
6. Solving common problems
If the screen is not duplicated or the image is slowing down, check the following points:
| Problem. | Possible cause | Decision |
|---|---|---|
| The TV is not displayed in the list of devices | Wi-Fi Direct is disabled on TV | Enable Settings → Network → Wi-Fi Direct |
| Sound is transmitted, but the image is not. | Incompatible codec (often on Samsung phones) | Install the SoundAssistant app and select the AAC codec |
| Delay over 200 ms | Weak Wi-Fi signal or background processes | Connect your phone to 5 GHz and close all applications |
| The phone screen does not fit on TV. | Wrong aspect ratio | In Miracast settings, select the Mode Fit under the screen |
To diagnose connection problems on your Xiaomi TV, go to Settings → About → Error Log. It displays fault codes, such as:
- ERROR 1003 is an HDCP problem (usually with uncertified cables).
- ERROR 2001 is an incompatible version of Miracast (requires a TV firmware update).
💡
If after connecting via HDMI on the TV screen appear artifacts (strips, flicker), try in the settings of the phone to turn off HDR or reduce the resolution to 1080p.
7. Comparison of methods: which one to choose?
Each way you duplicate your screen has its pros and cons, and here's a quick comparison table for you to choose from:
| Method | Delay. | Max, permission. | Sound support | Difficulty setting up |
|---|---|---|---|---|
| Miracast | 60-80 ms. | 1080p | Yes (Android 10+) | ⭐⭐ |
| Google Cast | 100-150 ms. | 4K (content only) | Yes. | ⭐ |
| HDMI-adapter | 0-10 ms. | 4K@60Hz | Yes. | ⭐⭐⭐ |
| AirPlay (for iPhone) | 80-120 ms. | 1080p | Yes. | ⭐⭐ |
| ApowerMirror | 40-200 ms. | 1080p | Yes. | ⭐⭐⭐ |
It's perfect for games. HDMI-Adapter (minimum delay), for movies – Google Cast (best picture quality), and for presentations – Miracast or ApowerMirror (configurement of management).
⚠️ Note: When using Miracast on Xiaomi Mi TVs TV 4S (2019) may have a problem with “breaking the connection” in 10-15 minutes, due to the energy-saving mode of the Wi-Fi module. Solution: turn off the option Automatic Wi-Fi disconnection in the settings of the TV.
