How to make a mirror screen on a Xiaomi phone: all ways + error solving

You want to stream your Xiaomi screen to a big TV, but don’t know where to start? Screen mirroring allows you to duplicate your smartphone’s image on TV in real time — it’s convenient for watching photos, games, presentations, or even streaming videos. However, on Xiaomi devices (especially on Redmi Note models, POCO and Mi flagships), this process has nuances, from MIUI versions to support for Miracast and Google Cast protocols.

In this article, we will discuss 5 working ways of mirroring the screen – from wireless (via Wi-Fi and Miracast) to wired (via HDMI and USB-C), and also tell you how to eliminate typical errors: image delay up to 2 seconds when playing, connection breaks and no sound. Particular attention will be paid to the models Xiaomi 13/14, Redmi Note 12 and POCO F5, where the connection algorithm is different from older devices.

Mirror through Miracast (wireless method)

Miracast is the standard for wireless screen transfer without a router, built into most modern TVs (starting with Android TV 5.0+) and supported by all Xiaomi smartphones on MIUI 12 and later, the main advantage is the minimal latency (about 50–100 ms), which is critical for gaming.

To activate Miracast:

• 📱 Open the Settings. → Connections and sharing → Screen transmission.
• 🔍 Press the Wireless Display (or Miracast on older versions) MIUI).
• 🖥️ Turn on Miracast on your TV (usually in the menu) → Screen Mirroring).
• 🔗 Select your TV name from the list of available devices.

If the TV is not on the list, check:

• ⚡ Both devices are connected to the same Wi-Fi network (even if Miracast runs without a router, some TVs require it).
• 🔄 Restart your TV and smartphone – sometimes the Wi-Fi Direct module freezes».
• 📶 Make sure your TV is on Screen Mirroring (Samsung - Smart View, on the TV) LG — Miracast).

⚠️ Note: Xiaomi with MediaTek processors (e.g. Redmi Note 11 or POCO M4 Pro) Miracast may not work properly because of drivers, in which case try an alternative way through Google Cast.

2. Screen transfer via Google Cast (Chromecast)

If your TV supports Google Cast (built into Android TV or via Chromecast), this method is simpler and more stable than Miracast, the main plus is the ability to broadcast only audio (such as music from Spotify) or individual applications (such as YouTube), without duplicating the entire screen.

Instructions:

1. Make sure your smartphone and TV are connected to the same Wi-Fi network.
2. Open an app that supports Google Cast (like YouTube or Google Photos).
3. Slip on the broadcast icon (📺) and choose your TV.
4. To fully mirror the screen, use the option of Transfer the screen in the notification curtain (on MIUI 13+).

If the Google Cast icon is not displayed:

• 🔧 Check if Google Play Services are enabled in the settings (Settings) → Annexes → Application management → Google Play Services).
• 📥 Update the app you’re trying to stream (like YouTube).
• 🌐 Reconnect to Wi-Fi – sometimes the router blocks the multicast packets required for Google Cast.

3. Wired connection via HDMI (for minimum delay)

If you want maximum stability (for example, to stream games or watch movies in 4K), wired connection via HDMI is the best choice. latency with this method is less than 20 ms, and the image quality is independent of Wi-Fi interference.

You'll need:

• 🔌 adapter USB-C → HDMI (For new Xiaomi models or Micro-USB → HDMI (old).
• 📺 HDMI-cable 2.0 support 4K@60Hz).

Step-by-step:

1. Connect the adapter to the smartphone, and the HDMI cable to the adapter and TV.
2. On the TV, select the HDMI signal source.
3. On the smartphone, a notification will appear about connecting an external display - select the Duplicate screen mode.

⚠️ Note: On devices with MediaTek Helio G (e.g. Redmi Note 11) when connected via HDMI Solution: Use an external Bluetooth speaker or an adapter with Audio Return Channel support (ARC).

💡

If the TV image is cropped around the edges, zoom in on the TV settings (usually called Just Scan or 1:1 Pixel Mapping).

4. mirroring via USB-C (DisplayPort Alt Mode)

Modern Xiaomi smartphones (starting with the Mi 10 and Redmi K30) support the DisplayPort Alt Mode standard, which allows you to transfer video and audio over USB-C without additional adapters (only a USB-C → HDMI cable is needed), which provides better quality than wireless methods, but requires a compatible cable.

How to check for DisplayPort Alt Mode support:

• 🔍 Look at the characteristics of your model on the official website of Xiaomi (section Interfaces).
• 📋 Or use the DevCheck app (hardware tab) → USB).

If your smartphone supports this mode, simply connect it to your TV with a USB-C → HDMI cable. The screen should be duplicated automatically. If not, try:

• 🔄 Reboot your smartphone with a connected cable.
• 🔧 Enable the developer mode and activate the debugging option USB (Sometimes it helps to initialize the DisplayPort).

5. Use of third-party applications (for older models)

If your Xiaomi is released before 2018 (like the Redmi 5 or Mi A1), built-in mirroring features may not be available.

• 📱 ApowerMirror – works via Wi-Fi, supports management of PC.
• 🎮 TeamViewer QuickSupport - broadcast screen with the possibility of remote control.
• 📺 Screen Stream Mirroring – Optimized for TV streaming.

Cons of this method:

• ⏱ Delay of up to 1-2 seconds (not suitable for gaming).
• 📶 Requires stable Wi-Fi (with a weak signal, the image "breaks»).
• 🔒 Some apps show ads or require a paid subscription.

Instructions for ApowerMirror:

1. Install the app on your smartphone and TV (if on Android TV).
2. Connect both devices to the same Wi-Fi network.
3. Run ApowerMirror on your smartphone and select M (Mirror).
4. On the TV, confirm the connection.

💡

The app side is the only way to mirror devices on MIUI 9 and below, but they consume a lot of battery and can slow down.

6. Solving common problems

Even after successful connectivity, Xiaomi users face common errors.

🔴 Problem: Mirror works, but there is no sound

Causes and solutions:

• 🔊 Nana MIUI 14 The default sound can only be transmitted through the phone's speaker. Solution: In the notification panel, tap on the mirror notification and select Transmit the sound to TV.
• 🎧 If Bluetooth headphones are connected, turn them off – audio output priority may be lost.
• 🔌 When wired through HDMI Check if your adapter supports audio transmission (cheap adapters often only transmit video).

🟡 Problem: Image delay (lag)

Wireless methods (Miracast, Google Cast) always have a latency.

• 📶 Connect to the router at 5 GHz (instead of 2.4 GHz).
• 🎮 In games, reduce the graphical settings to 720p — This will reduce the load on the processor.
• 🔌 For critical tasks (such as cloud gaming), use a wired connection.

🟢 Problem: TV is not on the list of devices

Possible causes:

• 🔄 Screen Mirroring is not on the TV (on Samsung it can be called Smart View).
• 📋 Outdated firmware MIUI — Update your smartphone to the latest version.
• 🛠 On some Xiaomi models (e.g. Mi) 9T) To activate it, type the dial code: ##225466##
