scrcpy is a free and open source application to display and control Android devices connected via USB (or wirelessly, but with lower performance) from a Linux, Windows or macOS desktop. scrcpy focuses on lightness, performance and quality, offering 30~60 FPS, with a resolution of 1920x1080 or more. It also has a low latency, somewhere between 70 and 100 ms. I must say scrcpy's performance surprised me when I first tried it, it almost felt like I was having the Android device in my hand, and not using it remotely from my Linux desktop computer.
