Xiaomi’s Wireless Display feature: What it is, how it works and how to set up

If you’ve ever dreamed of streaming your Xiaomi screen to a large TV without any extra wires, the wireless display feature is exactly what you need. This technology allows you to mirror the contents of your smartphone screen to external devices: TVs, monitors or projectors using Miracast, AirPlay standards (for Apple) TV) But how does it work in practice, what models support this feature, and what pitfalls can you encounter? In this guide, we'll go through everything from theory to step-by-step tuning.

To be clear, a wireless display is not the same as a Google Cast (like YouTube or Netflix), which only transfers content from a particular app, while Wireless Display duplicates the entire screen of a smartphone in real time, including notifications, games and system menus, making the technology versatile, but also imposes more stringent hardware and network requirements.

What is a wireless display and why you need it

Wireless Display (or “Wireless Display” in Russian) MIUI) — This is an implementation of the Miracast standard, which allows you to transfer video and audio from your smartphone to an external screen over Wi-Fi Direct. DLNA Google Cast, no connection to the shared network: devices connect directly, which reduces latency and increases stability.

Main use cases:

• 🎮 Big screen games: connect your smartphone to your TV and play Genshin Impact or Call of Duty Mobile with a gamepad like on a console.
• 🎬 Watch movies and streams: stream videos from any apps (including pirated or regionally restricted ones) that aren’t on Smart TV.
• 📊 Presentations and demonstrations: Show slides, photos or diagrams on a projector without any HDMI-cable.
• 🔧 Diagnostics and configuration: it is convenient to use a large screen to work with ADB ordebugging.

It is important to understand that a wireless display is not always a Miracast, and depending on the Xiaomi model and external device, you can use:

• 🔄 Miracast (standard for most Android devices) TV and Windows devices).
• 🍎 AirPlay (Apple only) TV TVs with AirPlay 2 support).
• 📺 Wireless HDMI (Proprietary solutions, for example, in Xiaomi Mi TVs TV).

What Xiaomi smartphones support Wireless Display

Not all Xiaomi devices have a wireless display function, depending on the model, version, and the model. MIUI And the hardware. These are the key criteria:

1. hardware support for Wi-Fi Direct and Miracast:

Wi-Fi module should support the mode P2P (Peer-to-Peer, which is typical for Qualcomm Snapdragon chipsets (600 series and above) and MediaTek Helio (G90 Budget models on Snapdragon 4xx or older MediaTek (e.g. Helio) P22) often deprived of this function.

2. Version MIUI:

The function appeared in MIUI 10, but only works with stable MIUI 12 and later: Some devices (e.g. Redmi Note 8 Pro) may not have it even with hardware support due to firmware limitations.

List of popular models with Wireless Display support:

⚠️ Note: Some models (e.g. Redmi) 9A or POCO M3) Wireless Display may not be on the menu even if the chipset supports it, and installing custom firmware or using third-party apps like ApowerMirror will help.

How to turn on the wireless display on Xiaomi: step-by-step instructions

The connection process depends on the version MIUI, But the general circuitry is the same for most devices:

Step 1. Check the compatibility of the TV

Make sure your TV or monitor supports Miracast (usually listed on the specs as "Wireless Display", "Screen Mirroring" or "Wi-Fi Direct"). On Xiaomi TVs, the feature is called Wireless Display and is located in the Settings menu. → Connections.

Step 2: Activate the TV mode

• For Xiaomi Mi. TV: Settings → Wireless networks → Wireless display.

Step 3: Enable Wireless Display on Xiaomi

Open it on your smartphone:

Settings → Connections and Sharing → Wireless Display

If there is no item, try an alternative path:

Settings → Additionally. → Laboratory → Wireless display

Make sure the TV supports Miracast

Enable Wi-Fi and Bluetooth on your smartphone

Shut down. VPN Proxies (they can block the system) P2P-linkage)

Charge your smartphone at least 30% (broadcasting consumes a lot of battery)

Restart router if connection is not established-->

Step 4. Connect to the TV.

Common Problems and Their Solutions

Even with the right setup, users often face difficulties, and here are the most common ones and ways to fix them:

1. Image delay (lag)

When streaming games or videos, there may be a delay of 100-300 ms. This is due to the features of Miracast, which is not optimized for low latency.

• 🔌 Use 5 GHz Wi-Fi (if the TV supports).
• 📶 Reduce the distance between devices (optimally up to 3 meters).
• 🎮 For games, it is better to connect wired through USB-C → HDMI adapter.

2. No sound during broadcast

Sometimes it's a video, but it's a smartphone.

• 🔇 The TV does not support Miracast audio transmission (rarely, but it does happen).
• 🎧 In the settings MIUI The wrong audio output is selected. Check: Settings → Sound. → Sound output.
• 🔄 Reconnect the devices or reset them.

3.The connection is constantly breaking.

If the broadcast stops every 10 to 30 seconds, the problem may be:

• 📡 Interference from other Wi-Fi networks. Try changing the router channel.
• 🔋 A discharged smartphone battery (at a charge level below 15% MIUI It may limit productivity).
• 🛠️ Firmware incompatibility. MIUI and TV until the latest versions.

Alternative ways to broadcast the screen with Xiaomi

If Wireless Display doesn’t work or isn’t on your device, there are a few alternatives:

1. Google Cast (Chromecast)

Suitable for streaming content from supported apps (YouTube, Netflix, Google Photos) does not duplicate the entire screen, but works more stable with video. Requires a Chromecast device or a TV with built-in Google Cast.

Applications for mirroring

• 📱 ApowerMirror: Supports broadcasting on Windows/Mac TVs, but with a delay. ~200 miss.
• 🖥️ TeamViewer QuickSupport: More suitable for remote help, but can duplicate the screen.
• 🎮 Steam Link: Optimized for gaming, but requires a powerful router.

3. Wired connection via adapter

Use it for minimal delay USB-C → HDMI Adapter (e.g. Xiaomi) USB-C to HDMI). This solution is free of lag and connection break problems but requires cable.

⚠️ Warning: Third-party mirroring applications often require both devices to connect to the same Wi-Fi network, whereas Miracast works without a router.

💡

If you often broadcast the screen to the TV, turn on the Settings → Battery → Performance mode is the High Performance option. This will reduce lags, but increase battery consumption.

Comparison of Wireless Display with other broadcast technologies

To choose the best way to connect, compare Wireless Display with the alternatives:

💡

For games and videos with high latency requirements, it is better to use a wired connection (USB-C → HDMI). Wireless Display is suitable for presentations, streams and non-interactive content.

How to Improve the Quality of Wireless Display

If the image is “braking” or tearing, try these optimization methods:

1. Set up the router.

• 📶 Switch to 5 GHz (if the TV supports).
• 🔄 Select a channel with minimal interference (use applications like Wi-Fi Analyzer).
• 🚫 Disable devices that consume bandwidth (for example, torrent clients).

2. Optimize the settings of Xiaomi

• 🔋 Enable Performance Mode: Settings → Battery → Performance mode → Tall.
• 📵 Turn it off. VPN, Proxy and background applications.
• 🔄 Reduce screen resolution (if the TV only supports the screen) 720p, broadcast 1080p lay down).

3. Use specialized applications

For games, try Moonlight (requires) NVIDIA GPU PC) or Rainway – these are optimized for low latency but require a powerful router.
