Why the phone doesn’t connect to the Xiaomi TV: all the reasons and ways to fix it

You try to stream video from your phone to the big screen, but Xiaomi TV stubbornly ignores connection attempts? Or does the TV screen flash and then emit an error "Device not supported"? The problem of connecting your smartphone to Xiaomi TVs (Mi TV A series, Mi TV Q, Redmi Smart TV, etc.) is more common than it seems — and the reasons are not only in network settings. 80% of cases are to blame for incompatible wireless transmission protocols, outdated software or banal errors of the user when choosing a connection mode.

In this article, we’ll look at all the possible scenarios why a phone (whether it’s an iPhone, Samsung, Xiaomi or another brand) can’t connect to a Xiaomi TV — via Wi-Fi Direct, Miracast, DLNA or HDMI/USB-C cable. You’ll get not only a diagnostic checklist, but also unique solutions for Xiaomi models with Amlogic and MediaTek processors that often ignore even service centers.

1. Checking the compatibility of the phone and TV Xiaomi

Before digging into the settings, make sure your devices are technically capable of interoperating. Xiaomi TVs support multiple wireless transmission protocols, but not all of them work with all smartphones.

• 📱 Miracast: It works on Android 4.2+ Windows 8.1+, But iPhone (even with iOS 16)+) It does not support it, only through third-party applications such as ApowerMirror.
• 📶 Wi-Fi Direct: Must be enabled on both devices, but some phones (e.g. Samsung Galaxy) S22) Requires manual connection confirmation.
• 🔌 HDMI: To connect via cable, the phone must support MHL or USB-C Alt Mode (Xiaomi has a model with a Snapdragon processor) 8xx).
• 🌐 DLNA/UPnP: It only works to transfer media files (photos, videos, music) but not to duplicate screens.

Pay special attention to the TV firmware versions. Xiaomi Mi TV 4S (2018-2019) models based on PatchWall 1.0 often conflict with Android 12+ phones due to the outdated Wi-Fi Display protocol stack. Update TV software through Settings → About TV → System update – this solves the problem in 60% of cases.

2. Wi-Fi connection errors: from network to DNS

If the phone and the Xiaomi TV are on the same network, but the connection is not established, the problem lies in the configuration of Wi-Fi.

• 🔄 Double. NAT: If the router and the TV are handing out Wi-Fi at the same time (Point of Access mode on TV), the devices can't see each other. → Network → Access point.
• 🔒 Isolation of clients (AP Isolation: enabled in router settings (often by default for TP-Link and ASUS). Disable it in the router administrator panel.
• 📡 Different frequency bands: the phone is 5 GHz and the TV is 2.4 GHz (or vice versa.
• 🌍 DNS-problems: if the TV can't resolve the phone name on the local network. DNS 8.8.8.8 in the TV network settings.

For diagnostics, use the Fing app (Android/iOS) to show if devices can see each other on the network. If pinging between the phone and the TV passes (192.168.x.x) but the connection is not established, the problem is in the transmission protocol (see next section).

3. Miracast and Wi-Fi Direct: Why Xiaomi TVs Can't See Phones

Miracast (aka Wi-Fi Display) is the most capricious protocol for connecting your phone to Xiaomi TV. If the TV screen blinks and returns the “failed to connect” error, follow these steps:

1. Reboot both devices. Yes, it's trivial, but it helps 30 percent of the time -- especially if the phone has previously connected to another TV.
2. Turn on Miracast on your TV: Settings → Connections → Wireless Display → Turn on some models (Redmi Smart TV X) the other way: Settings → Devices → Phone screen.
3. Turn off Bluetooth on your phone – it may conflict with Wi-Fi Direct.
4. Use the bridge app if the standard Miracast doesn't work: For Android: Google Home, ApowerMirror. For iPhone: Screen Mirroring (requires Apple TV or Roku as an intermediary).

If your phone still doesn't find the device after you turn on the Wi-Fi Display on your TV, check the regional settings. Some Xiaomi TV models (especially for the Chinese market) block Miracast outside Asia. The solution is to change the TV region to India or Russia in Settings → Language and Region.

4.Disorders with HDMI and USB-C: cable, adapters, ports

The cable connection should be the most reliable, but there are some nuances here too. If the phone is not detected by a Xiaomi TV via HDMI, check:

For Xiaomi phones (like Redmi Note 11 Pro)+ or POCO F4) Active adapter required USB-C → HDMI DisplayPort Alt Mode: Cheap passive adapters (up to 500) ₽) Recommended models: Baseus 6-in-1 or UGREEN 10073.

💡

If your phone supports DeX (such as Samsung Galaxy), turn on this mode before connecting to HDMI, so the connection will be more stable.

5. firmware update: why it solves 60% of the problems

Xiaomi TVs on the Amlogic S905 processors (models 2018-2020) have a critical bug in the Wi-Fi Display stack, which is fixed only in newer firmware than 2.3.65. If your TV is released before 2021 and not updated, most likely, this is the problem.

How to update the firmware correctly:

1. Check the current version in Settings → About TV → PatchWall version.
2. If the update via the Internet does not help, download the firmware manually from the official website (choose the version for your model!).
3. Write the.zip file to the flash drive (format) FAT32), put it in USB-port of the TV and run the update via Settings → Updating the system → Local Update.

After the update, reset the network:

Settings → Network → Additional → Resetting network settings

This will clear the Wi-Fi module cache that could have conflicted with the phone.

💡

If Miracast doesn’t work after the update, try rolling back the firmware to version 2.3.55, which is more stable in some regions.

6. Resetting and alternative ways of connecting

If none of these things worked, you'll have to do a hard reset or workaround, and start with the safest one.

⚠️ Warning: Resetting the TV to factory settings will remove all installed apps, accounts and personal data. Write down the image and sound settings (or take a picture of them) in advance). 🔄 Network reset (without data loss): Settings → Network → Additionally. → Resetting network settings 🧹 Full reset (removes everything): Settings → On TV. → Reset to factory settings 📱 Alternative applications: LocalCast (for DLNA) TeamViewer QuickSupport (for remote control) Steam Link (for gamers) If even after resetting the phone does not connect, the problem may be a hardware malfunction of the Wi-Fi TV module. TV 4A (2017-2018, where the module AP6255 The solution is to contact a service center to replace the module (cost) ~1500–2500 ₽). 7.
