A method of using multiple display devices (usually video projectors) to create a single large image. Edge blending may included as a feature of the projectors, as part of a media server, or as presentation display system.
Edge blending solves two problems: 1) Multiple, smaller, less-expensive projectors can be used, and 2) Less throw distance is needed, which is often a problem in theatres when using rear projection.
