Ultra high resolution real-time display system is composed of graphics processing system, ultra high resolution monitor. Its displaying resolution is 2048×2048, non-interleaved, 8-bit per pixel. The image input speed is max to 240 MB/s. It can display real-time image data of n(n=8,4,2,1 )CCD cameras simultaneously, and can process sampling m pixels from every n pixels (n=8,4,2,1; m=8,4,2,1; n≥m). This system can be widely used the satellite station and real-time display of the aerial image, medical image and other sensor's high resolution image.
