R5976214 VisuPlus Video Insertion Unit June 2003
4-5
4.1.3 Output Units
Module Overlapping Windows
If the VISU
PLUS
is equipped with analog output units and a window is positioned on multiple pro-
jection modules, at the vertical border of a module two pixels are not displayed. One can choose
whether two pixels on the left or two pixels on the right or one pixel on each side is not displayed.
Displaying RGB windows with more than 1024x768 Pixels
The following remarks must be considered when displaying RGB windows, due to the internal
output line size of 1024 bit per row of the output card:
Output resolutions up to 1024 pixels per row can be displayed without any limitation.
At higher resolutions the pixels will be scaled to fit in the buffer. A resolution of 1280×1024
will then internally be stored at 640×1024 pixels. To overcome this the horizontal size will be
doubled towards the projector.
An RGB input of 800×600 pixels is optimally displayed:
At an output resolution of 1024×768
The RGB window needs not to be enlarged. All pixels fit in the line buffer.
At an output resolution of 1280×1024
If the RGB window is doubled to a size of 1600.
If orbiting is required, there has to be an overlap of 16 pixels between 2 outputs. Since this over-
lapping area has to be contained within the same buffer size of 1024, the usable resolution has to
be reduced further to 1008 (=1024-16) horizontally. In order to keep the aspect ratio correct, the
output resolution of 1008 x 756 per screen is the best choice for optimal usage of the V
