A display controller (3) includes a controller input (300,301 ) connectable to receive first image data representing a non-safety relevant part of an image to be displayed on a display (5) and to receive second image data representing a safety relevant part of the image. A merging unit (31 ) is connected to the controller input (300,301 ), for composing the image from the first image data and second image data. A controller output (33) is connectable to the display, for outputting display data representing the image. An image monitor (4) is connected to the controller output (33), for comparing a part of the image corresponding to the safety relevant part with an reference for the part.
