A head up display arrangement for a motor vehicle includes an image source emitting a light field. A first freeform mirror is positioned to provide a first reflection of the light field. A generally concave second freeform mirror is positioned to receive the first reflection and provide a second reflection of the light field. The second reflection is reflected off of a windshield of the vehicle so as to be visible to a driver of the vehicle as a virtual image. The generally concave second freeform mirror includes a reflective surface having a shape such that the virtual image appears to be curved to the driver of the vehicle.
