It is a research hotspot and difficult to display the Internet resources of ultra-high resolution effectively and quickly in the fields of satellite remote sensing, urban environmental monitoring and early warning, and smart city management center. This study proposes a parallel ultra-high resolution display technology that based on cluster which combines Web technology and cluster parallel processing technology perfectly. The technology overcomes many problems of the traditional centralized information processing display and the display resolution limit of DLP projection splicing technology, system splicing difficulties, slow information display processing speed, unable to different shared, etc., enables the real-time high resolution display of the Web resources. Through contrast experiments, the clustered Web parallel ultra-high resolution display technology proposed in this study can display Web resources efficiently and in high definition, which provides an effective solution for real-time and ultra-high resolution display of massive Web information content.
