WindoWall Pro Series • Special Application: Edge Blending 65

The edges of the projected images overlap by a few pixels. However, to the viewer, the

videowall appears to contain one seamless image, with no indication of where the edges of

the component images are.

NOTE: The WindoWall Pro does not manage the contrast adjustments and brightness

compensation needed to visually blend the image edges so that the overlapped edges

are not brighter than the rest of the image. With the WindoWall Console software, the

processor can manage the video information so that the information in the blended

areas is the same on adjacent projectors.

Figure 43 shows a system in which three projectors produce a display consisting of eight

windows. In this illustration, each cross-hatched area represents the blended area that

two projectors are responsible for displaying. The top diagram shows the projector images

overlapping. Because the images overlap, the video information in the overlap area is

identical on both projectors.
