Data Doubling
This menu item is used to enable or disable the overlap of adjacent video sources. Selections are ON to enable data
doubling or OFF to disable data doubling. Use the Overlap Width menu item to specify the width of the data doubled
(overlapped) area and the Justification selection to select whether the source material is left or center-justified on the
wide screen.
Justification
This menu item allows the user to adjust the output display justification. The available justification values are
CENTER and LEFT. Center justification is not available with more than 7 projectors. Data Doubling must be turned
ON for this setting to take effect.
Overlap Width
This menu item allows the user to adjust the width of the edge blending by adjusting the Width parameter. The width
can be from 64 to 640 pixels. The maximum overlap width for a given display application is determined by the total
number of projectors and the input horizontal size. The maximum overlap is HACTIVE/(total projectors-1). For a
1024x768 input, the maximum overlap width with 3 projectors would be 512 pixels. This setting has no effect unless
Data Doubling is turned ON. The alignment test pattern (ALIGN) is always automatically tailored to support the
specified overlap width.
Feathering Setup Menu
The Feathering Setup menu is used to access a submenu where edge blending adjustments are performed. The
content of this submenu is controlled by the Blend Level setting. Please refer to Section 2 for more information on
Gamma and Feathering.
Feathering Setup Menu with BASIC Blend Level Selected
The adjustments in this menu are applied to all projectors connected to the BlendPRO.
Gamma
The gamma of the edge blending curve is controlled by the Gamma parameter. The gamma factor may be from 1.0 to
5.0.
