7. Random Access Adjustment Mode
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)
7.5.6 ScenergiX overlap zone (vertical scenergix)
Definitions
Image 7-11
Scenergix overlap zone vertical
Overlap : number of pixels that overlap
Vertical resolution of 1 projector : 768 for Graphics versions, 1024 for Reality versions, 1050 for SXGA projectors.
Total vertical screen resolution : [(Vertical resolution of 1 projector) x 2] minus (overlap)
Vertical Resolution source : number of active lines of the source
Adjustment of Active lines (Lact) of the first projector
1. Go to File –> Edit menu of first projector.
2. Enter value for vertical act (= Lact) as follows :
Lact = [(vert.. resolution of 1 projector)/(Total Vert. screen resolution)] x (Verti. resolution source)
3. Vertical start (= Lstart) remains the same.
Adjustment of Active lines (Lact) of second projector
1. Go to File –> Edit menu of second projector.
2. Enter value for vertical act (= Lact) as follows :
Lact = [(Vert.. resolution of 1 projector)/(Total vert. screen resolution)] x (vert. resolution source)
3. Vertical start (= Lstart) = original start + [(Vert. resolution source) minus (newly calculated Lact)]
Example
Vertical resolution source : 1200 lines
Vertical resolution projector 1 & 2: 768 lines
Overlap : 50 lines
Total vertical screen size : 1486 lines
Lact projector 1 = (768 / 1486) x 1200 = 620 lines
Lact projector 2 = (768 / 1486/) x 1200 = 620 lines
