Why does not turn on the wireless display on the Xiaomi TV: a full analysis of the problems

Wireless screen broadcast from your phone or laptop to your Xiaomi TV via Miracast or Wi-Fi Display should work out of the box — but in practice, users face connection errors, black screen or complete lack of response. The problem can lie in the settings of the TV itself (Mi TV 4A/4S/5 Pro series, Redmi Smart TV, etc.), as well as in external factors: router, signal source or even interfering devices on the network.

In this article, we will discuss all possible causes of a broken wireless display on Xiaomi, from the banal (turned off Wi-Fi) to the complex (firmware conflict), you will learn how to diagnose the problem by symptoms, which settings to check first, and what to do if the TV “can’t see” your device or displays an error failed to connect.

For convenience, we've created a quick diagnostics chart that can help you identify the root of the problem in 1-2 minutes, and if you've tried standard methods, at the end of the article you'll find rare solutions that aren't written about in the official instructions.

1. Check the basic conditions for Miracast/Wi-Fi Display

Before digging deep into the settings, make sure the minimum requirements for wireless broadcasting are met. Errors are 60% of the time - users simply miss the obvious.

• 📶 Wi-Fi is enabled on both devices (Xiaomi TV and signal source). TV Wireless display only works when connected to a single network.
• 🔄 Miracast Mode is activated in TV settings: go to Settings → Connections → Wireless display (on some firmware, the path may differ).
• 📱 Source supports Miracast: smartphones on Android 4.2+ (Other than some Samsung models with Smart View, Windows laptops 8.1/10/11 (Wireless Display Driver must be installed).
• 🔌 The TV is stable: at low voltage, the Wi-Fi module can shut down. Try another power cable or outlet.

If one of the conditions is not met, the wireless display will not work. For example, on Xiaomi Mi TV 4S 55" when the Wi-Fi button is turned off, the Wireless display button in the menu becomes inactive, but users often miss this point.

2. Typical connection errors and their significance

Xiaomi TVs, when you have problems with Miracast, display standard error messages, decrypt them and tell you what to do in each case:

If your error didn’t make it to the table, check the TV Event Log: Go to Settings → On TV. → Error logs. There may be details, like code 1006 (problem with the code). DHCP) or 2003 (conflict) IP-address).

💡

On Xiaomi TVs with PatchWall 3.0+ firmware, the wireless display may conflict with Game Mode. Try turning off game mode before connecting.

3. router settings that block Miracast

In 30 percent of cases, the problem is not with the TV, but with the router. Miracast uses multicast traffic and requires certain network settings that can be disabled by default.

• 🌐 AP Isolation -- needs to be turned off. Insulation on blocks device interactions on the same network.
• 🔄 IGMP Snooping – Enable this feature (usually in the section below) LAN It optimizes multicast traffic.
• 📡 5GHz band – Miracast works better at 5GHz. If your router is dual-band, connect the TV and source to a 5GHz network.
• 🔒 Filtration MAC-Addresses – make sure that MAC-TV addresses and signal source are not blocked.

On Xiaomi Mi Router routers, the path to settings is: Wi-Fi settings → Additional → IGMP Snooping. TP-Link: Additional settings → Network → IGMP Proxy. If you are not sure, reset the router to factory settings and reset the network.

4.Rights with Xiaomi TV firmware

Outdated or “curved” firmware is a common cause of a wireless display that is broken. Xiaomi regularly releases updates to fix Miracast bugs, but not all users install them.

1. Go to Settings → About TV → System Update.
2. If you have an update, install it. It takes 10 to 15 minutes, and the TV will restart.
3. After the update, reset the network settings: Settings → Network → Reset network settings.

If automatic updates don't work, try manual firmware via USB.

1. Download the latest firmware for your model from the official Xiaomi website (support section).
2. Unpack the archive and copy the update.zip file to the flash drive (FAT32 format).
3. Insert the flash drive into the TV, go to Settings → About TV → Update via USB.

Download firmware from the official website | Format the flash drive in FAT32| Check the file name (update.zip)| Do not turn off the TV during the update | After the update, reset the network settings

-->

Some models (e.g. Mi TV 4A 32) reset HDMI-CEC settings after the update, which may affect Miracast performance. Check this setting in Settings → HDMI-CEC and turn it on.

💡

If the wireless display stopped working after the firmware update, reset to factory settings (Settings → About TV → Reset).

5. Conflicts with other devices on the network

Few people know, but Miracast can be affected by other gadgets connected to the same router.

• 🎮 Game consoles (PlayStation, Xbox) in online gaming mode create a high load on the network.
• 📹 IP-Smart speakers or cameras (e.g. Xiaomi Mi) AI Speaker can block multicast ports.
• 💻 Laptops on VPN or Torrent clients.
• 📱 Smartphones in access point mode (if connected to the same router).

To check the impact of other devices:

1. Disconnect all gadgets from the router, except the TV and the signal source.
2. Try connecting Miracast again.
3. If it works, turn on the device one at a time to identify the “culprit”.

Especially often, problems are caused by devices with Wi-Fi Direct or Bluetooth-tetethering enabled. For example, if the Redmi Note 10 smartphone is on modem mode, it can conflict with Miracast on the TV.

6. Alternative ways to broadcast the screen on Xiaomi TV

If Miracast never worked, don’t despair – there are alternative protocols and devices for wireless broadcasting:

For iPhone or iPad owners, AirPlay is the best option. On Xiaomi Mi TV 5 and later, this feature is supported out of the box after upgrading to PatchWall 4.0+.

1. Go to Settings → Connections → AirPlay.
2. Activate the option and follow the instructions on the screen.
3. On the iPhone, swipe up for the control panel and select Screen Mirroring.

💡

If you have a Xiaomi TV without AirPlay but with Android TV, install the AirScreen app from Google Play.It emulates Apple TV and lets you use AirPlay.

7. Resetting settings and extreme measures

If neither of these methods worked, you'll have to reset your TV or call the service, but before you do that, try:

• 🔧 Resetting network settings: Settings → Network → Resetting network settings. This will delete all stored Wi-Fi networks and passwords.
• 🔄 Reset to factory settings: Settings → On TV. → Reset.Caution: This will delete all installed apps and accounts.
• 🛠️ Hardware malfunction check: if Miracast doesn't work after reset, it could cause a Wi-Fi module to break down.

On Xiaomi Mi TV 4 and older, you may need to re-activate the Wireless Display feature in the menu after reset, and check if the hotel mode is on (Settings → Hotel Mode) – it blocks many features, including Miracast.

⚠️ Note: Xiaomi TVs with firmware older than 2020 may not support modern Wi-Fi 6 or WPA3. If your router only works in these modes, switch it to Wi-Fi 5 (802.11ac) or WPA2.
