Can't record the screen with OBS Studio

Question

I have two screens and want to create a video of my work on Display 2.

So, added a source 'Display Capture'. What happens is in neither of the displays I'm able to see. Added anyways, clicked "Start Recording" but was getting black screen.

I tested also:

different sources, more precisely Window Capture (which doesn't suit my needs and sometimes works, sometimes doesn't and I didn't yet figure out why) and Game Capture (which never worked).
"Run as Administrator" and faced the same result.
Remove the HDMI cable and plug back in

Edit

Just gone through the following troubleshooting steps

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

and still no success...

TLDR; Settings > Graphics > Browse OBS > Options > Power Saving

Go to your Windows Settings (gear icon in the start menu)
Search for Graphics Settings
Select Desktop or Classic App
Select Browse and find the obs64.exe path - which is typically located here:
```
C:\Program Files\obs-studio\bin\64bit\obs64.exe
```
Go to the Options
Set to Power Savings
