Face detection app <a-camera> zoomed in on monitors

Hey,

I’m building an A-frame AR face detection app.
I have some issue to understand why on my laptops’ screens the camera rendering is zoomed in ?
When I launch my built-in camera app i have a completely different view from what i have in my browser with my AR app - it’s zoomed in

In the documentation I have seen the “far” and “fov” attribute for but it didn’t change anything? Any help possible ? I would like the camera to have no zoom.

Thanks !
