Record my Screen - Not Full Screen Appearing

[federicomim10]

Hi,

I want to record my full screen while myself explaining a concept and I started trying 'Clips' for that. 

My problem is that I record a video of my screen in Zoom but only part of my screen is shown while the rest is a black background. How do I resolve this ?

Also is 'Clips' the best alternative or it can also work doing a Zoom Meeting myself and recording it ?
