Why Xiaomi phone doesn’t connect to TV via Wi-Fi: a complete troubleshooting guide

Modern Xiaomi smartphones (including the Redmi series, POCO and the flagship Mi/Xiaomi 13) support wireless screen broadcasting to TVs via Wi-Fi Direct, Miracast or proprietary solutions like Mi Screen Sharing. However, users often face problems: the phone does not find TV in the list of devices, the connection is cut off after a few seconds or the image is lagging, the reasons lie in both the settings of the phone and the limitations of the TV or router.

In this article, we will analyze all possible fault scenarios - from banal disconnected Wi-Fi to conflict versions of firmware. MIUI and TV-You will learn how to diagnose a problem by symptoms (for example, if the phone sees the TV but can’t connect – Miracast is responsible for 90% of cases), which settings to check first, and how to circumvent manufacturers’ restrictions. Separately consider the nuances for Xiaomi TVs TV, Samsung, LG Sony Bravia and Mi Box S and Mi TV boxes TV Stick.

If you've tried to reboot your devices and turn Wi-Fi on and off, don't waste your time. 80 percent of the time, the problem is solved by changing one setting in your network settings or updating your firmware, and let's start with the obvious one: checking device compatibility.

1. Compatibility Check: Does your Xiaomi and TV support the same protocol?

The first thing to do is make sure the phone and TV speak the same language. Wireless screen broadcasting works through three main protocols: Wi-Fi Direct (direct connection without a router), Miracast (standard for mirroring), and DLNA (for transferring media files). Xiaomi uses all three, but with nuances.

For example, phones on MIUI 12+ try to connect via Miracast by default, but many budget TVs (especially the older Samsung or LG models until 2018) only support Wi-Fi Direct. And Xiaomi TV A2/A Pro 2023 TVs require Mi Screen Sharing to be enabled manually.

How to check compatibility:

• 📱 On the phone: go to Settings → Connections and sharing → If there's a Miracast or Wi-Fi Display, your Xiaomi supports mirroring.
• 📺 On TV: on the menu, look for Network, Screen or Wireless projection. For Samsung, it's Screen Mirroring. LG — Smart Share, for Xiaomi TV — Mi Screen Sharing.
• 🔍 Model check: if your TV is released before 2016, chances are it doesn't support Miracast. TV Stick).

If both devices support the same protocol but don't connect, move on to the next section. If you don't, you'll have to use alternative methods (which we'll talk about at the end of this article).

2. Phone Settings: What is stopping the Xiaomi-side connection?

Even if the protocols are compatible, the problem may lie in the settings of the smartphone itself, most often to blame: disconnected Wi-Fi Direct, power saving mode, outdated MIUI firmware or conflict with VPN.

Step-by-step diagnostics:

1. Turn on Wi-Fi Direct: go to Settings → Connections and Sharing → Wi-Fi Direct and activate the function. On some models (such as POCO F5), this item is hidden - you need to turn on screen transfer first.
2. Turn off the power saving mode: go to Settings → Battery → Power saving mode and select High Performance. Otherwise, the system may block the background data transfer.
3. Update MIUI: Outdated versions (below MIUI 13) often have bugs with Miracast. Check for updates in Settings → About Phone → System Update.
4. Turn off VPN/Proxy: If you use Warp, NordVPN or other services, they can block local connections. Go to Settings → VPN and deactivate them.

If after these actions the phone still does not see the TV, try resetting the network settings:

Settings → Connections and Sharing → Resetting Wi-Fi, Mobile Network and Bluetooth

Enable Wi-Fi Direct

Turn off the power saving mode

Update MIUI to the latest version

Disable VPN/Proxy

Reset your network settings (if nothing helps)-->

⚠️ Attention: on phones with MIUI 14 and newer Screen Transfer may conflict with Google Cast. If you have Google Home installed, try removing it or disabling auto-start.

3. TV settings: why does the TV not respond to the connection request?

The TV may ignore requests from Xiaomi for several reasons:

• 🔌 Reception mode is turned off: many TVs need to manually activate Screen Mirroring or Wi-Fi Direct.
• 🔒 Blocking New Devices: Some TVs (such as Sony Bravia) require remote-connection confirmation.
• 📶 Router conflict: If the TV is connected to Wi-Fi, it can block direct Wi-Fi Direct connections.
• 🔄 Outdated firmware: especially relevant for Xiaomi TV Until 2020, without an update, they won’t support new versions of Miracast.

Instructions for popular brands:

⚠️ Note: If your TV is connected to the Internet via cable (Ethernet), some models (Xiaomi) TV Q2, Redmi Smart TV) You automatically turn off Wi-Fi Direct, so you can either temporarily switch to Wi-Fi or use a Mi adapter. TV Stick.

4.Router problems: why does the home network interfere?

If you are trying to connect over a local network (not Wi-Fi Direct), the problem may be in the router settings, most often the fault is: network splitting (AP Isolation), blocking multicast, or incompatible Wi-Fi standard.

What to check:

• 🌐 Turn it off. AP Isolation: Go to your router settings (usually 192.168.0.1 or 192.168.1.1) and find the Wireless section. → AP Isolation: This feature blocks data exchange between devices on the same network.
• 🔄 Put on the multicast (IGMP): In the router settings, find IGMP Snooping or Multicast and activate it. DLNA will not work.
• 📶 Change the Wi-Fi standard: if the router is running in mode 802.11n (2.4 GHz, try switching to 802.11ac (5GHz Some Xiaomi TVs don't work well with outdated standards.

For Xiaomi routers (Mi Router 4A, AX3600, etc.), the instruction is simpler:

Open the Mi Wi-Fi app → Find your router → Wi-Fi settings → Additional → Turn off Customer Isolation

💡

If you have a dual-band router, try connecting your phone and TV to the same frequency (either both to 2.4 GHz or both to 5 GHz).

5. Firmware conflicts: Why are new versions of MIUI breaking the connection?

Xiaomi users often experience a screen transfer that stops working after the MIUI update, due to changes in the Miracast protocol or conflicts with Google services, for example, a bug appeared in MIUI 14 that causes the phone to not see Samsung TVs from 2020-2022.

How to fix it:

• 📲 Retracement to the previous version MIUI: If the problem has appeared after the update, you can return the old firmware through Fastboot (instructions for experienced users).
• 🔧 Disabling Google Play Services: Disabling Autoplay for Google Play Services sometimes helps (but it can disrupt other features).
• 🛠️ Manual Certificate Installation: Miracast requires up-to-date security certificates, which can be updated through Settings → System system → Date and time → Install automatically.

If you don’t want to risk firmware, try alternative ways to connect:

• 🔌 Through USB-C/HDMI: for phones with DisplayPort Alt Mode support (e.g. Xiaomi) 13 Pro).
• 📡 Chromecast: If you have a Google Chromecast or Mi TV Stick, use them for broadcasting.
• 💻 Through PC: Connect the phone to the computer USB, Then stream the screen to TV via Steam Link or Parsec.
