Edge-blending technology is becoming increasingly popular for supporting very large high-
resolution displays. The technology is very flexible and supports a wide range of screen
configurations. A typical three projector system is illustrated below.
As shown, multiple projectors are used to project on a common surface in order to create
one high-resolution image. The creation of a seamless image requires careful attention to
detail. High quality results depend upon a system-level approach that integrates content
creation, video processing, projector setup and system adjustments as described below.

two methods that are commonly used to generate wide-screen source material, each of
these methods is explained below.
