The existing research in the field of large-scale high-resolution display wall systems has mainly been focused on specific needs and environments. In many cases, the solutions built for large-scale high-resolution visualization are only valid for a specific use case (e.g. distributed 3D rendering, presentation of HTML content, stereoscopic projection). However, such solutions can soon become outdated and be left unmaintained (as seen with several distributed OpenGL library implementations). This happens due to the appearance of new technologies that solve the existing tasks in a more effective manner. A possible solution is to prevent most limitations on the set of technologies that can be used when the software is running on a display wall system. One way of achieving this is to use virtualization. This chapter presents Infiniviz – a virtual machine based high-resolution display wall system. Infiniviz approaches the visualization task in a seamless manner. The main aim of Infiniviz is to be able running any common desktop operating system software on a large scale high-resolution display wall without any modifications. Infiniviz achieves this by running a headless virtual machine with the required operating system backed by a custom software stack that handles the actual visualization. The authors have performed performance evaluations, virtualization environment comparisons and comparisons among other display wall architectures. This work along with key conclusions has been summarized in this chapter.
