Optimized content resolution: 3328*800 (This is the ideal resolution to set EDID)
Installation distance: 3m-4.25m
It is calculated from throw ratio and image wide for each projector. (2.5m*1.2=3m,
2.5m*1.7=4.25m)
The overlap value in video wall setting:
Projector LH: select RH edge: +197
Projector (Center): LH edge=+98, RH edge=+99 (total 197)
Projector RH: LH edge: +197
After finish setting, user can check the image, if some overlap area is still blurred,
please increase or decrease Overlap Value with 1-2 steps and select optimized one.
The final luminance is 819 Lux. It will be enough for inside room environment.

It is allowed to have different overlap pixel among all projectors. “Irregular” Spread Sheet” is
required to calculate the result.
4.4 Mark image location
After Excel Spread Sheet calculation, user can understand the final image position for each projector.
Please mark image position by paper adhesive tape on the screen. The positions should include 4
corners of the image for each projector and horizontal center line of the screen. Please select a tape
that will not damage the screen. Laser leveler is an ideal tool for marking center line, horizontal and
vertical image positions.
4.5 Set overlapped region size
a
、
During Excel Spread Sheet calculation, user has some flexibility to determine the overlap
region size by different projector resolution, lumens and number of projector.
a
、
Please reserve at least 214 overlapped pixels for XGA projector and 352 pixels for
1080P/WUXGA projector or 40cm-100cm overlapped region (it will also depend on screen size
and Excel calculation). GeoBox maximum edge blend region is 1000 pixels. If it is over 1000
pixels, user can change the projector installation location, lens shift adjustment, projector
display aspect ratio or reduce overlap region by geometry alignment.

[9x5 Curved] will cut the horizontal image into 8 sections and the image in each section can be
independently adjusted. In different output resolutions, there will be different pixel number in
each section: XGA: 1024/8=128, WXGA: 1280/8=160, 1080p: 1920/8=240. Usually, [9x5
Curved] alignment is enough for most of the curved screen edge blending.
c
、
If the overlapped area between two adjacent projectors has the same or multiple number as
above, the geometry alignment in overlap region will have less flexibility. User can increase or
decrease one or two grids (32 or 64 pixels) in overlap area to increase the flexibility for
accurate alignment between adjacent projectors.

Below figure is an example for [9x5 Curved] alignment in 1024 resolution:
25% overlap region:
The adjusting points in projector A & B will be at the same position in overlap region
