A computer program product for changing an aspect ratio in a display system comprising a first holographic system operable to display an image with a first aspect ratio and a second holographic system operable to display the image with a second aspect ratio different from said first aspect ratio, comprising a computer usable medium having machine readable code embodied therein for:

  • switching on the first holographic system so that the holographic system diffracts light passing therethrough to form an image with said first aspect ratio; and

    switching off the second holographic system so that the holographic system allows light to pass therethrough without diffraction of the light.
