How do I improve the quality of screen mirroring on my Mac?
To improve the quality of screen mirroring on your Mac, ensure that both your Mac and the device you’re trying to mirror to are connected to a fast and stable internet connection. A wired connection or a 5GHz Wi-Fi network can provide a more stable and faster connection than a 2.4GHz Wi-Fi network. You can also try reducing the resolution or quality of the screen mirroring to improve performance. Additionally, closing other apps or background processes on your Mac can help free up system resources and improve the screen mirroring experience.
Another way to improve the quality of screen mirroring is to use a device that supports 4K or high-definition video.

You can also try using a screen mirroring app that supports high-quality video, such as AirParrot or Reflector. These apps can provide a higher quality screen mirroring experience than the built-in AirPlay feature. By following these tips, you can enjoy a smoother and higher-quality screen mirroring experience on your Mac.
