Screen duplication via Miracast (Screen Mirroring)

5. File Transfer via DLNA/UPnP
The DLNA protocol allows you to stream videos, music and photos from your phone to your TV without duplicating the screen. On Xiaomi TV, the feature is called Media Server or Local Networks, and on the Galaxy A51, you will need a third-party app.
Instructions:

⚠️ Note: If the video slows down, reduce the bitrate in the application settings (for example, LocalCast has the option to Convert video). 4K-content recommended Wi-Fi speed of at least 100 Mbps.
6. Solving Connection Problems
If the TV can’t see the phone (or vice versa), check the following points:
| Problem. | Reason. | Decision |
|---|---|---|
| The devices don't find each other. | Different Wi-Fi networks or Wi-Fi Direct disabled | Connect both devices to the same router or activate Wi-Fi Direct |
| Lags for video transmission | Weak Wi-Fi signal or network congestion | Switch router to 5GHz channel or use HDMI |
| No sound at Miracast. | Protocol or phone settings limitations | Connect Bluetooth headphones to TV or use HDMI |
| Applications (Netflix) are not broadcast | DRM-Protection (Widevine) L1) | Use official apps on TV or HDMI |
Resetting network settings on the TV sometimes helps with persistent connection errors: Settings → Network and Internet → Additional → Network settings reset.
On the Galaxy A51, reset your Wi-Fi settings: Settings → General Management → Reset → Reset your network settings.
💡
If neither method works, check to see if your router is blocking the connection. Some models (such as the TP-Link Archer C6) have an AP Isolation feature that prohibits data exchange between devices on the same network.
