Question / Help Multiple monitors

[mjmorris335]

I have a desktop running six monitors attached to 3 separate NVIDIA cards. I want to capture the display of, say, Display 3 but OBS is only showing Display 0 & 1 as available.
When I do capture the display I want to introduce a live video feed into, say, the bottom right corner over the display. Am I right in thinking I would use a Window Capture source for that? At the moment all I'm getting is a blank or black window. I've looked through the Help wiki but can't find anything relevant si any advice would be greatly appreciated. Using Windows 10 and OBS 64.

You could use window capture, but you'd need to enable the SLi capture mode (which forces the capture to be copied to system ram, which is very slow compared to on-GPU capture). Multi-gpu systems are a nightmare for capture.

Ok. Thanks for that.
