Soft edge matching (option)
Multi-screens are popular for many applications. In these installations, the goal is
to obtain a contiguous matched image, forming one homogenous view. The soft
edge matching feature provides a solution to the annoying side effects when
adjusting two or more projected images next to each other. To improve this junction,
both images must be overlapping within a certain percentage of the total screen
width. During the overlapping period, both video signals are modulated by
appropriate waveforms so that the resulting light output equals the rest of the image.
