	placed vertically with respect to the screen.

	mirror are mounted in an extension chamber.
Line Crawl	Tendency of the eyes to follow the sequentially flashing
	scanned lines of interlaced scanning up or down the screen in

	light bulbs on a movie theatre marquee. Line crawl tends to
	reduce vertical resolution.

	With distorted linearity, lines in the grid are spaced closer
	together on one side of the image and farther apart on the
	other. The linearity adjustment is performed on green only
