can connect to external monitor with mac book pro 2021 14 inch but only the background is displayed

I choose the external monitor as extended display but only the background appears. This is a work laptop and not using my apple id. Is that an issue?

<< only the background appears >>


then it is working as designed. The additional display is displaying a portion of your new Extended Desktop. The displays are concatenated along an edge (of your choosing) and used TOGETHER as if they were one larger extended desktop:





Once you have dragged the blue Icons to the same orientation as the physical displays on your bench, the mouse moves freely across the boundary between displays, and can carry a window across as well.


if you leave the window split between both displays, it will scroll "the right way"..
