Scenergix set up
Overlap : number of pixels that overlap
Horizontal resolution of 1 projector : 1024 for Graphics versions, 1280 for Reality versions, 1400 for SXGA projectors.
Total horizontal screen resolution : [(horizontal resolution of 1 projector) x 2] minus overlap.
Horizontal Resolution source : number of active pixels of the source.
Adjustment of Active pixels (Pact) of the first projector
1. Go to File –> Edit menu of first projector.
2. Enter value for horizontal active (= Pact) as follows :
Pact = [(Horz. resolution of 1 projector)/(Total horz. screen resolution)] x (horz. resolution source)
3. Horizontal start (= Pstart) remains the same.
Adjustment of Active pixels (Pact) of second projector
1. Go to File –> Edit menu of second projector.
2. Enter value for horizontal active (= Pact) as follows :
Pact = [(Horz. resolution of 1 projector)/(Total horz. screen resolution)] x (horz. resolution source)
3. Horizontal start (= Pstart) = original start + [(Horz. resolution source) minus (newly calculated Pact)]
Example
Horizontal resolution source : 1600 pixels
horizontal resolution projector 1 & 2 : 1024 pixels
Overlap : 100 pixels
Total horizontal screen size in pixels : 1948 pixels
Pact projector 1 = [(1024 / 1948)] x 1600 = 841 pixels
Pact projector 2 = [(1024 / 1948)] x 1600 = 841 pixels
Pstart projector 2 = Pstart projector 1 + (1600 – 841)
