Understanding Channel, Stream, and Source
Grouped sources will appear glued together side-by-side (when tiled
horizontally) or top-to-bottom (when tiled vertically) on the display wall.
The grouped sources move as one image when moved around by the
mouse clicker and rearranged on the wall. A particular use of grouping
sources can be—taking a computer output spread over two or more
screens and displaying it together on the display wall as one group.
