16:9 Frame AR and variable Active AR
When the Active AR is larger than 2.33:1, the black areas are large enough to apply a 1.33x vertical stretching to
the picture without information lost. Then the picture geometry is restored to its original AR with the anamorphic
lens with seamless black masking using the higher definition.

Configure the DreamScaler3 THEATRE for the THEATRE System
The DreamScaler3 THEATRE has two additional tasks to ensure when coupled with a THEATRE System.
Anamorphic Pre-Processing
The DreamScaler3 can be programmed to apply a vertical stretch per resolution and input. Configure the
DreamScaler3 into THEATRE Mode to have it set automatically upon changing the Input Active Aspect Ratio:

select the Active AR that suits your video source
The vertical stretching is automatically set when the DreamScaler3 is configured in THEATRE Mode and if the Input
Active AR is larger than 2.33:1.
Note:
By applying a vertical stretch to the video source, the vertical resolution of the picture is greatly improved. The other
gain of this process is to activate the unused pixels of the display matrix of the projector, and it greatly improves the
brightness performances and render finer details in a constant image height (CIH) setup.
