Image 12-34
Warp adjustment: 2 x 2 mode
In 3 x 3 mode, the image side centers represent the level two anchor points, whereas the image center represents the level three
anchor point. Together with the higher level anchor points (level 1, four anchor points), we come to a total of nine (3 x 3) anchor
points in this geometry mode. This mode can be used to ne tune
the overlap area in multiple channel display systems and to make
corrections to meet curved and double curved screens.
