Why is the sound delayed?
Audio lag (desync) is often caused by video stream buffering. In the receiving software settings on your PC, you can try reducing the buffer size or changing the codec from H.264 to a more lightweight one, if available. Disabling your antivirus software during the broadcast also helps.
Some programs not only allow you to share your screen but also manage your file system. This is convenient for quickly transferring photos and videos without cables or cloud storage.
Using specialized gaming software
Windows' default tools are good for office tasks, but gaming requires more powerful solutions. Applications like ApowerMirror, LetsView or Scrcpy (for advanced users) provide lower input lag.
Program Scrcpy It works via USB or TCP/IP debugging and does not require installing a client on the phone. open source software, which provides the highest performance and minimal latency, which is critical for dynamic games.
To connect via Wi-Fi using Scrcpy You must first connect the phone with a cable once to activate debugging and set the port. After that, you can disconnect the cable.
☑️ Check before launching the game
In the settings of such software, you can often set the bitrate and resolution manually. Reducing the resolution to 1280x720 can significantly increase FPS during broadcasting if the internet channel is unstable.
Diagnosing problems and troubleshooting delays
If the image is choppy or the connection is constantly dropping, the problem lies in airwave congestion. Wi-Fi channels may conflict with neighboring routers. Use airwave analysis tools and switch your router to a clear channel.
Windows Firewall or antivirus software may be blocking incoming connections to the projector. Check the list of allowed applications and ensure that "Allow the connection" is checked for System and Discovery Services.
- 🔄 Restart the router and both devices (PC and smartphone).
- 📡 Move closer to the router to avoid packet loss.
