Today I installed OBS Studio 22.0.2 on a Windows 10 laptop with an intel integrated graphics card and intel process (no Nvidia or AMD). I have a laptop screen and monitor connected with "extend desktop" as my display settings. I created a Display Capture source and got a black screen. I tried a variety of things to fix it, but what eventually worked was to download version 21.1.2 and use obs32.exe NOT obs64.exe. The 64bit version still shows a black screen, but the 32 bit version works. That link is: https://github.com/obsproject/obs-studio/releases/tag/21.1.2
