The aligning a video image with an edge of a display screen, the video image being displayed by a scanning of lines of the display screen by at least one electron beam modulated by a modulation signal, including, for each scanned line of the screen, storing successive digital video data in a storage device; detecting the end of the scanning of the line preceding the scanned line; initiating a delay upon detection of the end of the scanning of the line preceding the scanned line; starting the reading, from the storage device, of the successive digital video data stored at the end of the delay; and providing the modulation signal based on the read successive digital video data.
