IQ-Wall: An Open Standard for Tiled Video Walls that Balances Flexibility, Usability, Performance, and Cost

Abstract
Tiled video walls are engaging, useful, and pervasive in our everyday environment. They can be especially attractive to higher education institutions looking to spur innovation in teaching, research, and collaboration. However, if not thoughtfully designed, video walls can be expensive, difficult to maintain, and provide only limited functionality. Indiana University has been working with video walls for more than 10 years, using them in a variety of settings to support faculty, staff, and students in a broad range of research, education, community engagement, and creative activities. This experience has led to the development of an open hardware and software standard for video walls that provides flexibility, usability, maintainability, and the lowest possible costs while still maintaining good performance and high visual quality. In this paper, we share the motivations and technical details behind this open standard, as well as the lessons learned in b uilding and supporting tiled video walls as multi-purpose displays.
