CA 2072745

A device stabilizes the width, height and position of a picture displayed on a picture area (1) of a TV set. The amplitude of the deflection in the horizontal and/or vertical direction is stabilized by adjusting a deflection parameter to reference values which can be corrected in function of signals from sensors that detect the position of the picture. The invention is used preferably in projection TV sets.
