Synchronization
A timing signal used to coordinate an action.
TheaterScope
An aspect ratio used in conjunction with a special anamorphic lens to display 2.35:1 images packed into a 16:9 frame.
Throw distance
The distance between the screen and the projector.
Throw ratio
The ratio of the throw distance to the screen width.
TRF (Throw ratio factor)
A special number used in calculating throw distances and throw ratios when the image does not ll the width of the DMD™.
The throw ratio for a particular lens is xed but assumes that the image lls the width of the DMD™. For images that do ll the full width of
the DMD™, TRF = 1. For images that do not ll the DMD™, TRF is effectively increased.
UXGA
A display resolution of 1600x1200 pixels with a 4:3 screen aspect ratio. (Stands for Ultra Extended Graphics Array.)
Vertical Scan Rate
The rate at which the frames of the incoming signal are refreshed. The rate is set by the vertical synchronization from the source and
measured in Hertz.
Vignetting
Optical cropping of the image caused by the components in the projection lens. This can happen if too much offset is applied when
positioning the image using the lens mount.
