Visual display systems that can accommodate off-angle viewing. In one embodiment, a visual display system includes a visual display device, such as a video display device, having a display screen configured to display visual images. The display screen can at least generally face a first direction that is angled relative to a viewing direction. The visual display system can further include an optical tilting device at least generally overlaying the display screen. The optical tilting device can include a refracting lens, such as a Fresnel lens or other device, configured to optically tilt the displayed images toward the viewing direction to facilitate viewing of the displayed images. In another embodiment, the visual display device can be carried by a seatback portion of a passenger seat.
