How it works v1.3

View of DLP Panel

The 4:3 panel is not entirely used when displaying
16:9 sources.

View of DLP Panel

Select "Anamorphic" in the "Screen" menu to stretch

the image vertically and fill the entire 4:3 panel with

16:9 sources. This utilizes full panel brightness and

resolution.

XGA Panel (1024x768)

16:9 Source uses
1024x576 pixels

Adding an anamorphic lens

The anamorphic lens
compresses the image
size vertically to fit the
screen appropriately.

The end result at the 16:9 screen is that the pixels and
spaces between the pixels have been reduced in size
vertically by 25%. The full XGA panel is being used
inside the projector utilizing the full 1024x768 pixels
and full panel brightness. The pixel structure at the
screen is now rectangular and smaller vertically by
25%. This is achieved optically by the anamophic lens

and gives the overall image at the screen 33% higher

resolution and 20% higher brightness without sacrificing

anything in the original aspect ratio of the source.

The Anamorphic Lens (NEC part number HT169-LENS) attaches to

the standard lens and does not change the throw distance of the
projector. There is a small amount of vertical shift of the image,
please refer to the installation guide for more information.
