W1 (PJ1) =366*2.5= 914 pixels (Projector #1)
W2 (PJ2 & PJ3) =366*5= 1829 pixels (Projector #2 & #3)
W3 (PJ4) =384*3= 1097 pixels (Projector #4)
Based on the above data, if we convert the image location by coordinate, W1 is from 0 to 914,
W2 is from 914 to 2743 (914+1829), W3 is from 2743 to 3840.
Video Wall settings:
User can set different Video Wall Zoom value for each projector separately. We assume to set Zoom
at H=4, V=1 for all projectors
W1: Zoom: H=4, V=1, Pan: H=1, V=1
o
Overlap: 3840/4=960, 914-960= -
46→ Right Edge =
-46, Other Edge=0
W3: Zoom: H=4, V=1, Pan: H=3, V=1,
o
Overlap: 3840/4=960, 1097-960=
+137→ Left Edge = +137, Other Edge=0
W2: The image captured for W2 should be 1829. User needs to calculate Video Wall
Overlap Pixel based on this resolution. If we set 320 overlap pixels, the overlap value in
video wall is 86 pixels.
Under this condition, the image cropped for PJ2 should be in the range from coordinate 914 to 1914.5
(914+1829/2+86=1914.5). The image for PJ3 should be in the range from coordinate 1742.5
(914+1829/2-86=1742.5) to 2743 (914+1829=2743).
PJ2 Video wall setting: Zoom: H=4, V=1, Pan: H=2, V=1. The standard coordinate after Zoom
setting will be from 3840/4=960 to 960*2=1920, Overlap value will be: Left Edge: 960-914=
46, Right Edge: 1914.5-1920= -5.5 (actual -5 or -6)
PJ3 Video wall setting: Zoom: H=4, V=1, Pan: H=3, V=1. The standard coordinate after Zoom
setting will be from 1920 (960*2=1920) to 2880 (960*3=2880), Overlap value will be: Left
Edge: 1920-1742.5= 177.5 (actual 177 or 178), Right Edge: 2743-2880= -137
After finishing video wall settings, user needs to set [Edge Blend] between PJ2 and PJ3 to
finish complete system settings.
