Recent developments in the fields of parallel rendering and high resolution tiled displays have made it possible to apply these technologies to build large and scalable stereo displays for use in Virtual Reality applications. This paper presents the implementation of a high-resolution stereo tiled display (2x8 tiles), built from lowcost commodity components. Among the problems that arise when building such a system, the most challenging is multi-projector alignment and calibration. We describe

We compare two implementations of this method: a single-pass and a two-pass rendering method to adjust projector images for alignment of the tiles. We demonstrate such a stereo-calibrated tiled display in action and we present recommendations for using this system to overcome remaining issues.
