Configure your system for Display Capture
If Display Capture is not working, chances are you need to set OBS to run on the Integrated GPU.

Display Capture for NVIDIA-based Laptops
Close OBS if it is currently open
Go to the NVIDIA Control Panel by right clicking on your desktop, and then clicking on “NVIDIA Control Panel”
Click on “Manage 3D Settings” if it is not already selected
Under the Program Settings tab, click the “Add” button under where it says “Select a program to customize:”
Navigate to the .exe path for OBS and add it to the list
Default paths are: C:\Program Files\obs-studio\bin\64bit\obs64.exe and C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe)
Make sure it is selected in the drop down list
Then, under where it says “Select the preferred graphics processor for this program” open the drop down and select “Integrated graphics” from the list
Save and apply, then open OBS and check Display Capture again
