				With a 16:9 screen and a

				lower portions of the screen are
		16:9 Screen
		(Cinema aspect ratio / no CineWide)		masked, but the geometry of the
				active image area is unchanged.
				With a 2.35:1 screen and a
		2.35:1 Image on		CineWide-equipped projector,
				the DHD Controller scales the
		2.35:1 Screen
		(Cinema aspect ratio / CineWide)		2.35:1 image so that the active
				image area fills the 16:9 chip
				surface, eliminating the black
				bars. The secondary,
				anamorphic lens then restores
				the proper geometry to the
				2.35:1 image.

				NON-linearly (more on the sides
		16:9 IImage on		than in the center) to fit a 2.35:1

720p HDTV Image

This means, for example, that 720p HDTV programs will display with unused pixels on all sides: 320 on the left and right sides and 180 above and below.

With SDTV and EDTV sources, the DHD Controller scales the image horizontally to achieve a 16:9 aspect ratio.
