Connecting Sources

Connect a digital media storage device or cinema server to one of the 292A or 292B input ports. For a list of
standard single-link SMPTE 292M Formats, see
5.7.2

Using an Anamorphic Lens

The standard zoom lens on the projector can display flat images because the native resolution and format of the
projector closely match the flat aspect ratio. The installation of an optional anamorphic lens requires that the
source material is resized to fill the digital micromirror device (DMD) and the pixels are horizontally stretched
so that the full 2.39 image width appears on-screen.

Using a Wide Converter Lens

The optional Wide Converter Lens (WCL) magnifies a flat image with a format of 1.85:1 to a scope image with
a 2.39:1 format, while maintaining the full resolution of the source material.
