A display system is provided for displaying graphical images on a radiant energy-responsive surface, such as that of a cathode ray tube, with a radiant energy beam which is displaced to a plurality of different image positions on the surface under the control of a position storage means for registering various digital representations respectively representative of a plurality of image positions. A compensating signal supply serves to supply various compensating digital representations which are respectively representative of the compensation required at the various image positions. Depending on the digital representations in the position storage means, the signal supply is controlled to provide a particular coded pattern of compensating digital signals. These compensating digital signals are then converted into analog compensating signals for compensating for a particular non-linear characteristic of the display system.
