How to Use a Wireless Display on Xiaomi: A Complete Guide from Connection to Eliminating Lags

Introduction: Why you need a wireless display on Xiaomi

Wireless screen technology turns Xiaomi’s smartphone into a full-fledged media center, allowing you to stream videos, games or presentations to the big screen wirelessly, which is convenient not only for watching movies, but also for showing photos, streaming games through cloud services or even dubbing your desktop on a PC monitor. However, many users face problems from lack of sound to constant connection breaks.

In this article, we will analyze all ways to connect a wireless display on Xiaomi, Redmi and other devices. POCO — From standard Miracast to proprietary solutions like AirPlay (on supported models), we will focus on adjusting latency, optimizing picture quality and solving common errors such as "Device not supported" or "No displays available".

It is important to understand that the possibilities of wireless broadcasting depend not only on the model of the smartphone, but also on the firmware. MIUI. For example, on Xiaomi 13 Pro with MIUI 14 Wireless Display Extended Mode with Support HDR10+, Whereas the budget Redmi Note 10 may not have Miracast audio, we'll take these nuances into account in the instructions.

What wireless display technology supports Xiaomi

Xiaomi devices use three main technologies for screen broadcasting:

• 📺 Miracast is a wireless video/audio transmission standard over Wi-Fi Direct. It works on all modern Xiaomi smartphones (starting with the introduction of the new model). MIUI It does not require internet but is sensitive to interference on the air.
• 🍎 AirPlay is a protocol from Apple supported by some Xiaomi flagships (e.g. Xiaomi) 12S Ultra or MIX Fold 2 after updating to MIUI 13.5+. Allows you to broadcast the screen on Apple TV or compatible television sets (LG, Samsung with AirPlay 2).
• 🌐 Wi-Fi Direct + DLNA — Alternative method for transferring media files (not screen!) to supported TVs DLNA. It is suitable for viewing photos or videos from the gallery, but not for duplication of the interface.

Miracast differs from AirPlay in latency and quality. Miracast usually gives a delay of 50-150 ms (critical for gaming), whereas AirPlay on modern devices reduces it to 30-70 ms. TV 4K or TV with tvOS, whereas Miracast works with most Smart TV Android TV webOS.

In practice, the choice of technology depends on your TV:

Xiaomi devices with Snapdragon 8 Gen 2 chipset (such as Xiaomi 13 Ultra) have a "Game Miracast" mode, which reduces latency to 40 ms by reducing the bitrate of the video, which is activated in the wireless display settings.
