here is something I just found that is weird to me.

My laptop with 3 external displays (4 total) , when set with the built-in display as the "make this my main display" check box checked, I can open quickbooks and display report zoom in details only on that screen or screen 4, but if I set monitor 2 as main, then i can open zoom details on all 4 monitors.  (all 4 displays are 4k 3840x2160

hope that helps yall as i need to have quickbooks not on the laptop screen.
