Duplicating the screen on the Xiaomi TV: 5 ways to connect + fixing errors

Why You Need Screen Duplication and How It Works on Xiaomi TV

Screen duplication (or mirroring) allows you to stream images from your smartphone, tablet or computer directly to the big screen of Xiaomi TV, a feature that is indispensable for presentations, watching high-resolution movies, streaming games or showing photos to friends. Unlike simple HDMI connectivity, wireless duplication eliminates wire confusion and allows freedom of movement.

Xiaomi TVs (Mi series) TV 4/4S/4A/4X/5/5X/Q1/Q2/P1 Supports multiple duplication protocols: Miracast (for Android), AirPlay (for Android) iPhone/iPad/Mac), DLNA (For multimedia, and Wi-Fi Direct, the method of choice depends on the source device and the firmware version of the TV. 2020–2026 Years usually support all standards out of the box, whereas older TVs may require software updates.

It is important to understand the difference between duplication and streaming: the first one transmits the entire screen of the device in real time (including notifications and interface), and the second one only selects content (for example, YouTube videos), in this article we will discuss both options, as well as solve typical problems such as image delay or lack of sound.

1. Preparing Xiaomi TV for screen duplication

Before connecting, make sure your Xiaomi TV is ready to receive the signal.

• 📺 Update the firmware: Go to Settings → On TV. → Update the system and install the latest version of the software. This will solve most compatibility problems.
• 🔄 Activate Wi-Fi: Duplication only works when you connect your TV and source to the same network (or via Wi-Fi Direct).
• 🔍 Check supported protocols: In the Settings menu → Connections → Wireless projection must be displayed by at least one available standard (Miracast/AirPlay).
• 🔌 Turn it off. VPN/Proxy: These services can block local device detection.

If the menu does not include “Wireless projection”, then your model does not support hardware duplication, in which case an external adapter (such as Xiaomi Mi TV Stick or Google Chromecast) connected to the HDMI port will help.

⚠️ Note: On Xiaomi TVs with firmware below MIUI TV 3.0 (released before 2019) may not support AirPlay. check the version in Settings → On TV.

2.Duplicate from Android Device (Miracast)

For owners of Xiaomi, Redmi, POCO or other Android devices, the Miracast protocol will work, and it works on most Xiaomi TVs without any additional applications.

If the connection fails, try:

• 🔄 Reboot both devices.
• 📶 Reconnect to Wi-Fi (use 5GHz band for less latency).
• 🔧 Enable the developer mode on your smartphone and activate the option Debugging over Wi-Fi (sometimes helps with Miracast errors).

7.Comparing Xiaomi TV with competitors in terms of duplication features

Xiaomi TVs offer one of the widest sets of duplication protocols among budget TVs, but are inferior to premium brands in stability.

Xiaomi’s main advantage is Wi-Fi Direct, which allows you to duplicate the screen without a router. However, compared to LG or Samsung, Xiaomi TVs are more likely to suffer from audio delays (especially on models with Amlogic S905) chips.

If you are critically interested in duplicating stability (for example, for professional streams), consider buying an external adapter such as:

• Xiaomi Mi TV Stick 2 (supportive 4K@60Hz, price. ~3000₽).
• Google Chromecast 4K (Best compatibility with Android, ~5000₽).
• Apple TV 4K (perfect for the Apple ecosystem, ~12000₽).
