A method for making uniform the colorimetric rendering of a display surface including several adjacent display screens ( 10 a , 10 b), comprising for each pair of adjacent screens ( 10 a, 10 b) steps of: periodically sampling ( 21 ) by a calculation device ( 5 ) image data in two corresponding screen ( 10 a, 10 b) areas ( 13 a, 13 b) in the pair of adjacent screens, analyzing ( 22, 23, 24 ) by the calculation device ( 5 ) image data sampled in each period to determine a difference in calorimetric rendering between the two screen areas, determining by a correction device ( 6 ) connected to the calculation device a process to be applied to the video stream to one of the two video systems controlling the two screens in the pair of adjacent screens, by applying a predetermined correction law to the difference in calorimetric rendering, and applying ( 26 ) by the correction device the process to said video system, in order to make the calorimetric rendering of the display surface uniform.
