Methods, apparatus and systems for geometric matching of virtual reality (VR) or augmented reality (AR) output contemporaneously with video output formatted for display on a 2D screen include a determination of value sets that when used in image processing cause an off-screen angular field of view of the at least one of the AR output object or the VR output object to have a fixed relationship to at least one of the angular field of view of the onscreen object or of the 2D screen. The AR/VR output object is outputted to an AR/VR display device and the user experience is improved by the geometric matching between objects observed on the AR/VR display device and corresponding objects appearing on the 2D screen.
