A video projection system has an image deflection device to provide additional mounting options for a projector. The deflection device selectively positions a mirror in front of the projection lens to deflect the video image away from the optical axis of the lens, thereby allowing the projector to be mounted without the lens facing the projection surface. The projector includes an image processor for selectively flipping the video image to accommodate a first mounting configuration in which the projector rests on a horizontal surface with the lens facing the projection surface, a second mounting configuration in which the projector is upside down and attached to a ceiling with the lens facing the projection surface, and a third mounting configuration in which the projector is attached to a vertical surface with the image deflection device mirror positioned in front of the lens to deflect the optical image toward the projection surface.
