Section 2: Basic Operation

Summary of Admin: Source Menu Options

• Resolution: Record the XY resolution of the incoming signal, such as 2048 (X) and 1080 (Y), or

1920 (X) and 1080 (Y). Resolution must match the incoming signal format (assuming all of it is to

be displayed) and may differ from the original resolution to recover.

• To capture/process all of the incoming data,

enter the full resolution of the incoming source

material or leave at 0 (default). Regardless of whether or not the original material has been

“squeezed” for use with an anamorphic lens, enter the current incoming resolution. This may not

necessarily match the resolution of the projector or the original filmed material, depending on how

the source was formatted before distribution. For example, an original 2048 x 1080 native source

supplied pre-squeezed as 1920 x 1080 requires a source file indicating this incoming 1920 x 1080

resolution.

• To capture only a portion of an incoming image full-screen—like a “zoom” function—

, enter the

approximate horizontal width and vertical height defining the area of the image to zoom in on. The

projector automatically scales a center area of this size so that it fills the projector’s 2048 x 1080

display and remaining data is ignored. It may be necessary to experiment with the values to

accurately zoom in on a precise area. Offset must also be defined to zoom in on an area other than

the center.

• Offset: Record how much incoming data to discard, essentially delaying the “starting” point for

processing. Leave at 0 to process all available data.Offsetting an image is achieved by defining how

much horizontal width and vertical height to discard. Offset coordinates can be particularly useful

when zooming in on a portion of the image—they establish the top-left corner location of the zoom

area, with Resolution determining the size of the area.

Leave offset at 0 (default) to:

• process all incoming data

• to zoom in at the center of the image

• to a positive or negative value, as described below:

• a positive XY value discards image data from top and/or left

• a negative XY value discards image data from bottom and/or right

• Aspect Ratio: Select an aspect ratio (width-to-height proportion) of the original cinema format to

recover, usually 2.39 or 1.85. In the event the source material is pre-scaled or compressed, choose

Custom and enter the desired aspect ratio. Adding the 1.25x anamorphic widens a “squeezed” image

back to its original “scope” aspect ratio. For sources that are not pre-squeezed, aspect ratio can be

left at 0 (nothing selected in menu).

• Save: Save current settings as the selected source file, which will be accessible from the Channel:

Page 1 menu.

• Restore: Cancel new (unsaved) source settings of resolution/offset/aspect ratio and restore

previously settings.

• Tes t: Apply current settings to the image without saving.
