I know that "black screen" is a common problem for OBS, but I have a very specific issue: I have tried to record the window with different softwares without problem. I have the problem of "black screen" only when I try to record the window of the software "SideSync" which mirrors the screen of a tablet Samsung on the laptop (it appears the borders of the software but not the interior). On the other hand, when I record the computer screen with the software's window open on the screen, it records normally without "black screen". My laptop has only one standard graphic card on board and no other advanced Nvidea graphic card . I have already tried: (1) put "power saving" for graphics settings ;(2) use compatibility with windows 7. I will be very grateful for any suggestion. Thank you.
