Simple, inexpensive, lightweight secondary display systems are provided which extract video data and a direct coupled (DC) voltage from the CardBus slot of a computer. The video data is converted to a video display signal in a video controller and preferably coupled to a head-wearable display (HWD) over an optical fiber. The HWD is powered by the DC voltage which is coupled to it by a metallic conductor bundled with the optical fiber. |
