A holographic display system for a motor vehicle includes a coherent light source for generating a beam of coherent light and a spatial light modulator (SLM) having a two-dimensional pixel array, which is encoded with a hologram for modulating a phase of the coherent light. The SLM generates a first diffracted beam associated with a main image and a second diffracted beam associated with a conjugate image, where the first and second diffracted beams are angularly spaced from one another by a first angle. The system further includes an optical component for angularly spacing the first and second diffracted beams from one another by a second angle that is larger than the first angle. The system further includes a display surface receiving the first diffracted beam from the optical component to display the main image, with the display surface being free of the second diffracted beam.
