I don't why even if I choose fit landscape width in reading pdf, there is still grey margin left on the both side.
I do not mean the white margin of the original document.

When I double click in the zoom mode, it perfectly enlarge that both white and grey margin disappeared, but when I click the button, it zooms out again.

Does anyone know how we can make the margin disappear effectively for pdf reading in prs-t1?

Thanks!
