Use computer's mouse to control Android device without mirroring and without losing control of your PC (like second display)

• [x] I have checked that a similar feature request does not already exist.

I found a few issues related to using scrcpy as a second display (i.e. inverting scrcpy), but that's not quite what I need.

My tablet sits next to my monitor. And sometimes I need to use it. I want to move the mouse cursor to it as if it were a second monitor. But not translate the windows screen to it, but just let me control the tablet itself.

Similarly with the keyboard.

Scrcpy actually has everything for this, but you need to tell the system that a second monitor has been connected.

No, it has not:

• SDL needs a focused window to capture input events
• with relative mouse (HID), once the mouse is on your device, we can't know where the mouse actually is on the device (so we can't know when it reaches the border of the screen), and we can only send relative moves, not absolute positions.

You can't activate focus when you move the mouse to the second display?

to tell the system that we have a second screen, we most likely need a separate video driver (judging by other programs for the second display). Theoretically, it can be used to detect cursor transfer to the second screen.
