How to connect a Xiaomi or Redmi phone to a TV via Wi-Fi: all working ways

You want to stream a Xiaomi or Redmi video to the big screen but you're confused about settings? Wireless Wi-Fi connectivity seems easy, but in practice, there are often problems: the TV can't find the phone, the picture slows down, and the sound is malfunctioning. In this article, we'll look at all the current ways of connecting, from standard Miracast to hidden MIUI firmware functions that work even on older models.

The main difference between wireless and HDMI wired is that there are no extra cables, but there are also downsides: possible image delays (latency) and dependence on network stability. We tested all methods on Redmi Note 12 Pro+, Xiaomi 13 Ultra and POCO X5 Pro phones with Samsung QLED, LG OLED and Xiaomi TV A2 TVs.

If your TV is released before 2018, it probably doesn’t have Wi-Fi Direct or Miracast built-in, which would require an additional device, an Android TV Box (like the Xiaomi Mi Box S) or a ChromeCast, which we’ll talk about in a separate section.

1. Connect via Wi-Fi Direct (the most versatile way)

Wi-Fi Direct is a technology that allows devices to connect directly, without a router. Almost all modern Xiaomi/Redmi smartphones and TVs (since 2016) support this protocol, with the main advantage of minimal signal latency (about 50–100 ms), which is critical for gaming or watching sports broadcasts.

To activate Wi-Fi Direct on your phone:

1. Open Settings → Connections and Sharing → Wi-Fi.
2. Slip on three dots in the upper right corner and select Wi-Fi Direct.
3. Turn on the feature and wait until the phone finds the available devices.

On TV:

• 📺 Samsung: Settings → General. → Network → Wi-Fi Direct.
• 📺 LG: Settings → Network → Wi-Fi Direct.
• 📺 Xiaomi/Sony: Settings → Network and Internet → Wi-Fi Direct.

Once connected, a successful connection notification will appear on the phone screen, and you can now stream the screen through Settings → Screen → Wireless display, or use apps like YouTube with Cast.

Updated firmware on both devices-->

⚠️ Warning: If the TV can’t see the phone, try restarting both devices and resetting the network settings on your smartphone (Settings) → System system → Resetting settings → Reset your Wi-Fi, mobile network and Bluetooth settings on some Redmi models (e.g. Redmi) 9A) Wi-Fi Direct is hidden – you need to enable it through the engineering menu (#4636##, Wi-Fi information section).

2.Use of Miracast (for Screen Mirroring-enabled TVs)

Miracast is a wireless screen broadcast standard built into Android since version 4.2. On Xiaomi/Redmi smartphones, it works through the Wireless Display feature (or Wireless Display in global firmware). The main plus is that there is no binding to specific brands, so the method is suitable even for older Screen Mirroring-enabled TVs.

Instructions for the telephone:

1. Open Settings → Connections and Sharing → Wireless display.
2. Activate device search.
3. Choose your TV from the list (the name usually matches the model, for example, Samsung UE55).
4. Confirm the connection on both devices.

On TV:

• 🔍 Samsung: Source → Screen Mirroring.
• 🔍 LG: Settings → Connection → Screen mirroring.
• 🔍 Xiaomi: Settings → The device → Wireless display.

If the image is slowing down, try:

• 📶 Switch Wi-Fi on your phone to 2.4 GHz (in router settings).
• 🔋 Turn off battery savings (Settings) → Battery → Performance mode).
• 🎮 Reduce the broadcast resolution in Miracast settings (if available).

3. Streaming via Google Cast (for Android TV and Chromecast)

If you have an Android TV (e.g., Xiaomi Mi TV, Sony Bravia) or Google Chromecast connected, the most convenient way is to use the Google Cast protocol. Unlike Miracast, it does not broadcast the entire screen, but only content from supported applications (YouTube, Netflix, Google Photos, etc.).

How to set up:

1. Make sure your phone and TV are connected to the same Wi-Fi network.
2. Open an app that supports Cast (like YouTube).
3. Slip on the broadcast icon (usually in the upper right corner).
4. Choose your TV from the list.

Advantages of the method:

• 🎥 No delays – video and sound synced perfectly.

5. Connection via router (DLNA and local area network)

If your TV supports DLNA (most models after 2015), you can stream media files (photos, videos, music) without mirroring the screen, a method that is less resource-intensive and works even on weak phones (Redmi 7A, Redmi 8).

How to set up:
