Share screen

[shaikhspeer]

I am facing a problem when I conduct a meeting and share a screen from MacBook.

When I PUT the screen on full screen, the participants see a big border around and the screen becomes smaller.

This doesn't happen when I conduct the same from any windows laptop. The screen size is my laptop (host) and participant is same. Then why it becomes smaller if I conduct the meeting from Mac ?

What setting needs to be changed?
