Generally, "Fill screen" will crop some of the picture if it doesn't
have the same proportions (aspect ratio) as the screen, that's what you
want. The other option, "Stretch to fill screen" will resize the
picture to match the proportions of the screen, and will distort the
image if it's not the same aspect ration as the physical screen.
