				With a 16:9 screen and a
				standard D-73d (without an
		2.35:1 Image on		anamorphic lens), the upper and
				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 an
		2.35:1 Image on		anamorphic lens, the DHD
				Controller scales the 2.35:1
		2.35:1 Screen
		(Cinema aspect ratio / CineWide)		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.
Virtual Cinema	V-CINE			A 16:9 image is scaled

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.
