What you want is the mirrored content to have the same aspect ratio as your computer size. To know the crop rectangle, you must know both the device size and your computer screen size.

the resolution of my pc screen is 1280x720

So you want to crop the device width of 1600 to 1280, i.e. crop 320 pixels, 160 on the left, 160 on the right:

scrcpy --crop 1280:720:160:0   # 1280x720 at offset (160,0)

so I remain :(

Your device is not 1600×720. Is it portrait (720×1600)? What is the output in the console when you start scrcpy-noconsole.bat?

It makes no sense to crop the mirroring so that your portrait device match your landscape computer screen.

This?

OK, so it's 720x1600. It makes no sense to crop 720x1600 it so that it fits in your 1280x720 screen, you'll get only a tiny part of your screen.

Scrcpy just mirrors the device, which is rendered on the phone at phone screen dimensions. You can then crop, but that just crops what is rendered on the phone, it will not magically render at your computer dimensions.

What you want is probably a secondary display: #1413 (comment)

Bien, entonces es 720x1600. No tiene sentido recortarlo a 720x1600 para que quepa en su pantalla de 1280x720, realmente solo una pequeña parte de su pantalla.

Scrcpy solo refleja el dispositivo, que se representa en el teléfono con las dimensiones de la pantalla del teléfono. Luego puede recortar, pero eso solo recorta lo que se renderiza en el teléfono, no se renderizará mágicamente en las dimensiones de su computadora.

exactly that I tried, but when I start a mock screen and try to open it with scrcpy I only get a black screen

OK, it's often the case on Android 9 (and sometimes on Android 10). So desktop mode will probably not work on your device.

[Leuhan77]

I have android 9, I don't have the option to enable desktop mode, but if I can simulate a second screen, is there no way for this to work?

[rom1v]

is there no way for this to work?

I don't think so.

Well, thanks for the help
