A method for displaying a video image on a display screen by a scanning of the display screen along lines inclined by a first angle with respect to a reference direction by at least one electron beam modulated by a modulation signal. The method includes the steps of storing at least partly the successive initial digital video data associated with the image to be displayed in a memory; transmitting new successive digital video data corresponding to the image which would be displayed based on the stored initial digital video data for a scanning of the display screen along lines inclined with respect to the reference direction by a second angle opposite to the first angle; and providing the modulation signal based on the new transmitted successive digital video data.
