Large screen display systems are common display systems nowadays. Especially projector-based PC cluster large screen display systems share most of large screen display system market and they are main research topics today. A lot of researchers research on cluster algorithms, computation power improvements, high performance graphic rendering technologies, high speed buses, networks, and HCIs. Also, remarkable research results are being published by technical leading groups. Whereas, following groups who want research on large screen display have difficulties even to build a test system. Unfortunately, there are not enough information to build large screen display systems. In this paper, we survey on projector-based PC cluster large screen display technologies that use distributed rendering.
