In this article, we will analyze all the current ways of broadcasting from Xiaomi to TV in the Internet. 2026 year, including hidden settings for models on MIUI 14/15 and avoiding common errors such as "device not found" or image delay, and focusing on the differences between wireless and wired methods, as well as compatibility with Samsung TVs, LG, Sony Bravia and Xiaomi TV.
1. Wireless broadcast via Miracast (built-in MIUI function)
Miracast is a wireless video transmission standard supported by all Xiaomi smartphones since the Redmi Note 5 and the Mi 8 flagships. The main advantage of the method is the lack of need for a router: the connection is established directly between the phone and the TV.

โ ๏ธ Attention: On TVs LG Over 2019, you may need to manually enable Miracast through Settings โ Network โ Miracast (Screen Share) Sony devices often require firmware updates to work smoothly.
Both devices are connected to the same Wi-Fi network (if you use a router)|The TV is enabled with Screen Mirroring mode | Xiaomi has power saving mode disabled for Cast| The distance between devices is not more than 5 meters-->
2.Using Google Cast (Chromecast) to stream content
If your TV supports Google Cast (built into Android TV models or Chromecast), you can only stream individual apps, such as YouTube, Netflix or Google Photos, which saves battery life and reduces the load on the smartphone processor.
Instructions:
- Connect your TV and smartphone to the same Wi-Fi network.
- Open a supported app (like YouTube) and tap the Cast icon (๐บ) top-right.
- Select your Chromecast or Android TV from the list.

|---|---|---|---|
| YouTube | โ Yes. | 4K HDR | 50โ100 |
| Netflix | โ Yes. | 1080p | 100โ150 |
| Google Photo | โ Yes. | Original | 200โ300 |
| TikTok | โ No. | โ | โ |
| Games (PUBG, Genshin Impact) | โ ๏ธ Just screen. | 1080p | 150โ250 |
โ ๏ธ Attention: When streaming games through Google Cast, the delay can reach 250 ms, making the method unsuitable for shooters or racing. HDMI Miracast in Game mode (available on the MIUI 14+).
3. Wired connection via HDMI (for minimum delay)
If you want a stable image without lags โ for example, to watch movies in 4K@60fps or stream games โ wired connection via HDMI remains the best choice. This will require a USB-C โ HDMI adapter (for new Xiaomi models) or Micro-USB โ HDMI (for older smartphones like Redmi 4X).
Step-by-step:
- ๐ Connect the adapter to your smartphone and connect it to your TV HDMI-cable.
- ๐ฑ On the Xiaomi screen, select the display mode: "Duplicate screen" or "Expand desktop" (the second option allows you to use TV as a second monitor).

If the image on the TV is cropped at the edges, go to Settings TV โ Screen โ Image Mode and select "Just Scan" or "1:1".
4. Broadcast via Wi-Fi Direct (for older TVs)
Wi-Fi Direct is an alternative to Miracast for TVs that donโt support modern protocols, which creates a direct network between devices, but can suffer from delays and low resolution (typically up to 720p).
How to connect:
- On the TV, activate Wi-Fi Direct (in the network menu or screen settings).
- On Xiaomi, go to Settings โ Wi-Fi โ Wi-Fi Direct and select your TV.
- Confirm the connection on both devices.
- Run the broadcast through Settings โ Connection and Sharing โ Broadcast.
โ ๏ธ Note: On Samsung J series TVs (2016-2017), Wi-Fi Direct may not work smoothly due to firmware limitations, in which case it will help to update the TV software or use Miracast via a router (both devices connect to the same network).
Why is Wi-Fi Direct slowing down?
5. Broadcasting with the help of third-party applications
If the built-in MIUI functionality doesnโt work, third-party apps like ApowerMirror, TeamViewer QuickSupport, or Screen Mirroring come to the rescue, supporting additional codecs and protocols, but may require you to install the server part on your TV (for example, via Android TV).
The best broadcasting apps:
- ๐ฏ ApowerMirror โ Supports screen recording and control from TV (latency) ~100 ms).
- ๐ฅ๏ธ TeamViewer QuickSupport โ suitable for remote help (but requires internet access).
- ๐ฑ Screen Mirroring (by MobZapp) โ optimized for MIUI It works without rooting.
๐ง Setting up ApowerMirror:
1. Install the app on Xiaomi and TV (if Android TV).
2 Connect both devices to the same network.
3. On your smartphone, select "Mirror to TV" and scan the QR- code from your TV screen.
4. Activate the "No Delay" mode in the application settings.โ ๏ธ Note: Apps like ApowerMirror can collect data about your device. โ Annexes โ ApowerMirror โ Disable unnecessary rights (e.g. access to contacts).

The app side is useful for broadcasting to TVs without Miracast (such as older Philips or Toshiba models), but is inferior to built-in stability and security solutions.
6. Solving typical broadcasting problems
Even when properly configured, users encounter errors such as "device not found", "no sound" or "connection break" and these are the most common causes and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| "No device found." | Wi-Fi or Bluetooth on TV is disabled | Turn on both networks in the settings of the TV |

| No sound when broadcasting | Xiaomi has the wrong audio output | Go to Settings. โ Sound. โ Sound output โ HDMI/Bluetooth |
| Resolution below 1080p | Limitation of an HDMI adapter or cable | Replace the cable with a certified High Speed HDMI |
| The connection is broken after 5-10 minutes | Power saving mode on Xiaomi | Add Cast to exceptions (Settings โ Battery โ Application Energy Consumption) |
๐ ๏ธ Additional advice:
- ๐ If the broadcast is lagging, try reducing Xiaomiโs screen resolution to 720p in the developer settings (Settings) โ The phone. โ Version. MIUI โ tap 7 times).
- ๐ถ For stable Wi-Fi, use mesh systems (for example, Xiaomi Mesh Router). AX3000) instead of regular routers.
- ๐ When connecting wired, check for support HDCP 2.2 on cable and adapter - without it 4K-Content (Netflix, Disney)+) will not reproduce.
