Abstract: In a raster display device, such as a cathode-ray tube, in which the display is computed on-the-fly, such as in the raster vector generator type, when the computation of a line, or group of lines, exceeds a given period, the raster scan is halted until the computation is complete. The line at which the scan is halted is retraced at reduced brightness, and without modulation by video information overflow, is detected by coincidence of a computation signal and line sync.
