OBS does not recognize my screen?

I have the following problem. And although if I try obs with my laptop to use with window recording then recognizes only a black background.

on my pc at home that works. Have the laptop in the meantime even put on new. Does not work anyway. Although I have the same set in both (laptop and desktop).

Normally one would see here also without starting the recording "what" one takes up

Must in the settings actually select the monitor as far as I know.

Do not know where the setting would be but if I make window recording it is not the same

although one chooses the window there
