Do you want to show photos from your vacation on the big screen, run a mobile game on your TV or stream a movie with Xiaomi without unnecessary wires? Wi-Fi is the most convenient solution, but not always obvious. Depending on the smartphone model (Redmi Note 12, POCO X5, Mi 13, etc.), MIUI versions and the type of TV (Samsung, LG, Xiaomi TV or Android TV), the ways of connecting can vary.
In this article, we will explore all the current methods of broadcasting from smartphone to TV, from standard Miracast to proprietary technologies like Google Cast and Xiaomi Screen Mirroring. You will learn how to avoid image delays, why the TV can not see the phone, and what to do if the sound is transmitted, and the picture is not. And also unique MIUI settings that speed up the connection by 2 times (this works even on budget models like Redmi A2).
1.Preparation: What you need to broadcast from Xiaomi to TV
Before trying to connect devices, check three key conditions:
- ๐ฑ Xiaomi smartphone based on Android 8.0+ (or MIUI 10+). Older versions may not have built-in broadcasting features.
- ๐บ A TV with Wi-Fi Direct, Miracast or Chromecast support, and most models after 2017 support at least one of these standards.
- ๐ Shared Wi-Fi network (for some methods) Phone and TV must be connected to the same router (except for Miracast, which runs without a router).
If your TV is released before 2016 or belongs to a budget lineup (for example, Xiaomi Mi). TV 3S), You may need an external adapter, such as Google Chromecast or Mi. TV Stick. These devices are connected. HDMI-port and add support for modern broadcast protocols.

3. Method 2: Google Cast (Chromecast) - for streaming video and music
Google Cast (or simply Cast) is a technology from Google that allows you to stream content from apps (YouTube, Netflix, Spotify) directly to your TV. Unlike Miracast, it doesn't transfer a smartphone screen, but only a media file, which reduces processor load and reduces latency.
How it works:

Instructions:
- On Xiaomi TV, open Settings โ Connection and Sharing โ Wireless display.
- On your smartphone, go to Settings โ Connections and Sharing โ Wireless display.
- Select your Mi TV from the list.
- Confirm the pairing code on both devices.
If the connection is interrupted:

5. Method 4: Smart View (for Samsung TVs)
If you have a Samsung TV (QLED, Crystal UHD or The Frame series), use Smart View technology. It is built into the firmware of Xiaomi smartphones and allows you to broadcast the screen without additional applications.

- ๐ Lags when watching video: in the settings of the TV (Settings) โ General. โ External devices) disable Autosetting permissions.
๐ก
Smart View works better when the TV and phone are connected to the same Wi-Fi network, even though the technology supports direct connection (Wi-Fi Direct).
6. Method 5: Third-party applications (for older models)
If the built-in techniques donโt work (e.g., on the Xiaomi Redmi 5A or 2015 TV), use third-party apps:
| Annex | Protocol | Pluses | Cons |
|---|---|---|---|
| Miracast Display | Miracast | Operating without router, low latency | Requires root on some devices |
| Screen Mirroring | Miracast/Google Cast | Supports 4K, a simple interface | Advertising in the free version |
| ApowerMirror | Wi-Fi/LAN | Screen recording, PC control | Paid subscription for 4K |
How to set up ApowerMirror (for example):
- Install the app on your smartphone and TV (if itโs Android TV).
- On your phone, launch ApowerMirror and select Mirror to TV.
- The scanner will find the TV, confirm the connection.

7. Problem Solving: Why the Broadcast Doesn't Work
If the screen is not broadcasting or the connection is constantly breaking, check:
- ๐ Power: Xiaomi with less than 15% battery life Miracast can automatically shut down.
- ๐ถ Wi-Fi: If your TV and phone are connected to different networks (e.g. 2.4GHz and 5GHz), Google Cast will not work.
- ๐ Firewall: on some routers (for example, TP-Link Archer) C6) You need to manually allow multicast-trafic for broadcasting.
- ๐ฑ MIUI-Optimization: in Settings โ Battery โ Select Performance Mode Without Limits for the Translation Application.
If the image is slowing down:
- ๐ฎ For games, reduce the screen resolution in Miracast settings (select 720p instead 1080p).
- ๐ถ Switch the router to a 5 GHz channel with a width of 80 MHz (in the router administrator panel).
- ๐ง Turn off image processing on the TV (Settings) โ Picture โ Image mode โ Standard).
