Display system for a vehicle operable by a user, the display system comprising: a graphics generator configured to acquire input safety critical data indicative of one or more operative parameters of the vehicle and generate, based on the input safety critical data, an intermediate video frame signal indicative of an intermediate video frame, wherein the intermediate video frame comprises a first frame region that is a visual representation of monitoring safety critical data and that includes encoding markers uniquely associated to the monitoring safety critical data, wherein the monitoring safety critical data and the input safety critical data reciprocally correspond in a condition of correct working of the graphics generator and do not reciprocally correspond in a condition of incorrect working of the graphics generator; a display control unit coupled to the graphics generator and configured to receive the intermediate video frame signal and determine the monitoring safety critical data based on the encoding markers; a display monitoring unit coupled to the display control unit and configured to receive both the input safety critical data and the monitoring safety critical data determined from the encoding markers, reciprocally compare the input safety critical data and the monitoring safety critical data and generate a command signal based on said comparison, the command signal being indicative of the correspondence, or of the lack of correspondence, between the input safety critical data and the monitoring safety critical data, wherein the display control unit is further configured to receive the command signal and, based on the command signal and the intermediate video frame and if the input safety critical data and the monitoring safety critical data correspond, generate a confirmed video frame signal indicative of a confirmed video frame that is configured to be displayed to the user and that is a visual representation of the monitoring safety critical data.
