Browser_mod : Set size of camera live view in it?

Hi there,

I have an entity camera and use the browser_mod (full screen on my tablet) to display the camera feed.
But as far as I see, it adapts the camera size to the width, so that I am missing the bottom of the picture.
How can I solve that ?
Is there a way I can still be in full screen, but adapt the width of the camera view so that the bottom of the image is showned ?

Browser_mod on the tablet missing the bottom of the screen :

Entity image is complete though :

Many Thanks !!
