Abstract
In recent years high-resolution displays have become more and more attractive due to their extended amount of screen real estate. They have been used to visualize very large data sets in different application fields. One can distinguish between two basic concepts. Multiple projectors can be used to create tiled display systems with moderate to high resolution. LCD-based systems combine highresolution with reasonable costs. Nevertheless, LCD-based setups have to cope with the bezels of monitors causing discontinuities in visualizations. Conventional approaches either ignore the bezels and accept deformations or compensate them by the cost of losing pixel information. Both techniques may not be acceptable depending on the application.
In this paper we present a new scalable hybrid approach that neither leads to discontinuities nor significant loss of information, by combining LCD and projector technologies. The Tiled HiRes Display Wall is enhanced with LowRes image information, which is projected on the bezels of the LCDs. We show that our hybrid display improves the usability of multi-monitor systems and demonstrate a setup on a 33 tiled display wall.
