Question / Help New user having trouble with black screen :(

[Shauna]

Hi all,

I'm just trying to record my desktop with the program. I made the source of my scene monitor capture and went to my nvidia control panel and changed OBS to run on the graphics card like it says to in all the helpful answers the internet provided. But all I can capture is a black screen with audio. What am I doing wrong?

nVidia optimus does not work well with OBS because it switches to intel when on the desktop.

so in the nvidia control panel, if you only need recording monitor then change it to intel graphics for OBS then in the video tab of OBS set it to intel as well. dont expect good performance out of this as it is only using intel for scaling and capture.
