To create a single large display area using multiple projectors, it is unavoidable to overlap the images from projectors to get well tiled displays. Without perfect alignment, the resulting video especially for moving objects shows up with the objectionable gap or bright seam. To eliminate or lessen the effect causing by overlapped images such that the banding becomes invisible, modifying the video overlapping edges becomes a very important feature in such an application. CV-101P DVI-I Edge Blender for Projectors with Gamma Correction offers users to adjust the overlapped range horizontally or vertically, single edge or both edges on the same display at the same time. In this way, eye-catching, super high resolution, and bright display can be readily achieved. Typical applications include education, advertising, virtual reality, digital cinema, and video game. In addition to handle overlapped edges, CV-101P is also built up with graphics format conversion, for instance, VGA to DVI or DVI to VGA.
