➢
In order to get optimized result in video wall [Overlap] value, user can use VNS Excel Spread
Sheet and apply an overlap pixel in the Spread Sheet to get a near integrate number in Video Wall
[Overlap] value, then select the grid size to match this overlap pixel.
➢
In low resolution projector with low overlap grid number, user can select a grid size to maximized
the overlap region to improve edge blending quality. For example, when the overlap pixel is only
186 pixels, if user selects 32x32 pixels as grid size, then user needs to reduce the grid size to only
160 pixels (5 grids) to let the grids from adjacent projector to stack together. If user selects a grid
size of 31x31, then user can keep 186 pixels (6 grids) as overlap pixels.
5.3. Geometry alignment
Geometry alignment is to align the image position to let the projection image match the screen and also
let image grids between two adjacent projectors be matched together. This step will take most of the time
for edge blending. User can execute geometry alignment through front panel keypad, remote controller,
PC tool or WebGui through Ethernet connection.
