The CRVS includes a screen display having a uniform resolution screen curvature, a projector for generating images that are shown on the display screen, a mirror and a frame. The mirror may be positioned relative to the screen and the projector to reflect images generated by the projector onto the display screen. A throw distance is measured between the projector and the display screen and is based on a specific design eye point and a field of view (FOV). The frame supports the screen display, the projector, and the mirror. The frame may have a plurality of bars that define the throw distance between the projector and the display screen. ## Claims ### Claim 1 A portable constant resolution visual system (CRVS), comprising: a screen display having a uniform resolution screen curvature;
