Experiences with Scalability of Display Walls

Immersive virtual environments require large-scale high resolution displays to match the human visual acuity. This drives the need to study scalability issues related to display wall systems. This paper reports our experiences in scaling up the display wall system at Princeton University from 8 to 24 projectors. We discuss scalability techniques for automatic projector calibration, cluster management, data distribution for still images, motion video, and multi-channel audio.
