How to connect AnyCast to a TV from a Xiaomi smartphone: all ways and solutions to problems

Broadcasting a smartphone screen to a big TV screen has become a common task, but when it comes to budget adapters like AnyCast, Xiaomi users often face nuances. The Miracast protocol, which underlies most wireless adapters, can behave unpredictable on Xiaomi devices, especially on older versions. MIUI In this article, we will discuss all the working ways to connect AnyCast (and its analogues) to a TV via a Xiaomi phone, including bypassing typical errors like “no signal” or “device is not supported".

Despite the seemingly simple process, many users miss key details, from choosing the right adapter mode (Miracast vs AirPlay) to setting up network settings on the TV itself. We tested the connection on more than 10 Xiaomi models (from Redmi Note 8 Pro to Mi 11 Ultra) and found patterns that will help save time. 8xx AnyCast streaming is more stable than on devices with MediaTek processors due to the features of Wi-Fi Direct drivers.

If you've already tried to connect and you've got an error, don't be quick to blame the adapter -- 60 percent of the time, the problem lies in the settings of your phone or TV. We'll take a step-by-step look at each step, from hardware preparation to troubleshooting, tailored to firmware specifics. MIUI 12–14.

1.What is AnyCast and why it doesn't always work with Xiaomi

AnyCast is a universal wireless adapter that converts the signal of a smartphone, tablet or PC into a format that is understandable to the TV through ports. HDMI or USB. The basis of its work is protocols:

• 🔄 Miracast is a wireless broadcast standard for Android (supported by all Xiaomi theoretically, but with reservations).
• 🍎 AirPlay – Apple’s protocol AnyCast emulates for iOS compatibility (not relevant on Xiaomi).
• 📶 DLNA — Transfer of media files, but not the entire screen (works stably, but with limitations).

The problem is that Xiaomi is actively modifying the standard Android, and in some versions, it is not. MIUI Miracast is either disabled by default or works with errors. POCO X3 Pro MIUI 13 stream via AnyCast is cut off every 5 minutes due to aggressive background optimization. 9A Adapter is not detected at all – here the legacy Wi-Fi Direct driver is to blame.

In addition, AnyCast itself comes in different versions:

• 📦 AnyCast M2/M3 — Miracast and AirPlay support, but can brake at resolution above 720p.
• 📦 AnyCast 4K — support 1080p/60fps, But in practice it only works with Android phones. 10+.
• 📦 Clones without a brand – often impersonate AnyCast, but use stripped-down protocols (e.g., only DLNA).

⚠️ Note: If your AnyCast requires a 2.4GHz Wi-Fi connection and Xiaomi phone automatically switches to 5GHz, broadcasting will be impossible.This is a typical problem for the Mi 10 and newer – manual range switching is required in the router settings.

2. Preparing Xiaomi phone for connection

Before you connect AnyCast, you need to configure the smartphone itself. Xiaomi devices have several pitfalls that can block the broadcast:

Step 1 Verification of the version MIUI Android

Open the Settings. → The phone and remember:

• 📱 Version MIUI (for example, MIUI 14.0.5).
• 🤖 Android version (such as Android 13).

If you have Android 9 or older, MIUI 11 or lower, there is a good chance that Miracast will not work smoothly, in which case we recommend updating the firmware or using alternative methods (see Section 5).

Step 2: Enable the "Wireless Display" function

The way to set up depends on the version MIUI:

1. For MIUI 12-14: Settings → Connection and sharing → Wireless display.
2. For MIUI 11 and below: Settings → Additionally. → Wireless display or screen → Wireless monitor.

If there is no item, then your model does not support Miracast at the software level (typical for budget Redmi until 2020).

Step 3: Set up the Developer Mode (optional)

For some models (POCO F3, Mi 9T) Requires to activate hidden options:

1. Go to Settings → About phone and 7 times click on the MIUI version.
2. Back to Settings → Additionally. → For developers.
3. Find Debugging over Wi-Fi and Without Background Traffic Restrictions – Enable both.
