SetOffset
Function Applies a position offset to the image on a specified output, to allow correct
stitching of the target display screens.

Arguments <output number> is the output channel number:
0 = Output 1
1 = Output 2

<horizontal offset> is an offset value measured in pixels. A negative value shifts
the image to the left, a positive number shifts it to the right.
<vertical offset> is an offset value measured in pixels. A negative value shifts the
image up, a positive number shifts it down.
