New player in need of an answer

So after playing for a few hours somethings been bugging me, the binoculars. this is what i see normally, cool its fine. But if i zoom in i see this I lose the sight of my binos and just a zoomed in screen, is this supposed to happen?

Also since im here i would like to know if there is anyway to make a scope take up more of my screen at the moment this is what i see and i cant really make out most of the markings in the scope.
