Present Movies

This section provides information and procedures for using the projector to present movies. It is recommended
that you read through this section in its entirety before displaying movies for the first time. Before you display
movies for the first time, verify that the projector is properly installed, aligned, and configured. See
Installation and
5.8.1

Connect 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
5.8.2

Use 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.

Use 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.

Masking

You use masking to conceal the unused edges of a screen. These are the two types of masking:
• Top Masking – Movable flat black panels or curtains are installed along the top edge of the screen. You raise
the curtain for flat images, and you lower the curtain for scope images.
• Side Masking – Movable flat black panels or curtains are installed on each side of the screen. You close the
curtain for flat images, and open the curtain for scope images.
