Therefore user can only do few lines image position adjustment in this direction and user may see some
garbage image in the blanking area. If user increases [Overlap] value to “+” in Right Edge, the image capture
range can be up to 900 pixels.
c. The image location shift range will depend on the input resolution. If the input resolution is 3840x2160, then
the maximum horizontal adjustment range will be around 104cm/3840*900=24cm. If the input is 1920x1080,
the maximum horizontal adjustment range will be around 104cm/1920x900=48cm. If the adjustment range is
not enough, user can add another GeoBox to extend the adjustment range.

Irregular TV wall position alignment
Example for irregular TV wall:
TV size: 47” (1040x585mm), TV resolution: 1920*1080, Signal source resolution: 3840*2160
Please note that if the signal source resolution is different, the pixel density in each measuring unit will be also
different. Once user finishes the [Overlap] value settings, the relative position in each LCD will keep the same
automatically and will not be affected by different resolution in input source. The output resolution setting in G-405
shall be the same for each TV and the TV can be with different size and resolution.
5.2.1 Procedures for position adjustment--[Overlap] setting:
The most convenient way is to measure the dimensions of the video wall and the position for each LCD to
determine the [Overlap] pixels for the adjustment.
a.
To draw an outline of the display area in the video wall. If user wants to keep 16:9 aspect ratio, the
outline should also be 16:9 aspect ratio and some display information may be lost.
b.
To split the display area into 2x2, mark the center lines and measure the value of X & Y.
c.
To calculate the pixel numbers in each measure unit, i.e. “mm” (pixel density)
Horizontal= 1920/X=X’
