QtScrcpy supports displaying and controlling Android devices via USB or over network. It does NOT require root privileges. It supports three major platforms: GNU/Linux, Windows and macOS. It focuses on: - lightness (displays only the device screen) - performance (30~60 fps) - quality (1920×1080 or above) - low latency (35~70ms) - low startup time (only about 1 second to display the first frame) non-intrusiveness (nothing will be installed on the device)
