That's just an artifact of the overlay used - you can specify any PNG to use instead. I like that effect, because on my 14" portable the vertical separation of the trinitron cells was more pronounced than the scanlines were, and the vertical bars look better to me.
For the other way on, use a PNG that includes a horizontal effect
