How does scaling / switching beetween devices work in simple mode?

I,
typically, I am recording clicks on one device.
Than I ex- and import those simple scripts to an ldplayer device.
That device is having half the resolution of the recording device (recording: 2400x1080 and playing: 1200x1040).

Officially, this is not supported, at least for images. Currently, I do not use images, i.e. its a simple scripts, only clicks and delays.

When I check the execution on the "player" device, I see that the clicks are approx. 90% reduced. MEaning, when I record a click on the top of the recording device, I see it on the playing device ~ 10% below the top.

I tried to change the screen size, the DPI, the window size. Alyways the same 10% missing (and clear: the targeted buttons are not hit ;-) .

What influences this "scaling" of the recording? What can I do, that the buttons are hit?
