Certain embodiments relate to systems and methods for presenting a stereoscopic, 3-dimensional image to a user. The system may comprise a mobile device having a camera and a pixel-selective mask overlaying a display. The system may perform facial and object recognition techniques to determine the location of the user's eyes. Subsequently, the system may adjust the mask so as to maintain an optimal stereoscopic effect for the user, regardless of the user's position.

In one example an electronic device includes a housing that includes an A/C input or DC input, and at least one circuit substrate that includes electronic circuitry, such as graphics processing circuitry that receives power based on the A/C input or DC input. The electronic device also includes a divided multi-connector element differential bus connector that is coupled to the electronic circuitry. The divided multi-connector element differential bus connector includes a single housing that connects with the circuit substrate and the connector housing includes therein a divided electronic contact configuration comprised of a first group of electrical contacts divided from an adjacent second group of mirrored electrical contacts wherein each group of electrical connects includes a row of at least lower and upper contacts.

In one example, the electronic device housing includes air flow passages, such as grills, adapted to provide air flow through the housing. The electronic device housing further includes a passive or active cooling mechanism such as a fan positioned to cool the circuitry during normal operation. In one example, the electronic device does not include a host processor and instead a host processor is in a separate electronic device that communicates with the graphics processing circuitry through the divided multi connector element differential bus connector. In another example, a CPU (or one or more CPUs) is also co-located on the circuit substrate with the circuitry to provide a type of parallel host processing capability with an external device.

A method includes reducing power of a first graphics processor by disabling or not using its rendering engine and leaving a display engine of the same first graphics processor capable of outputting display frames from a corresponding first frame buffer to a display. A display frame is rendered by a second graphics processor while the rendering engine of the first graphics processor is in a reduced power state, such as a non-rendering state. The rendered frame is stored in a corresponding second frame buffer of the second graphics processor, such as a local frame buffer and copied from the second frame buffer to the first frame buffer. The copied frame in the first frame buffer is then displayed on a display while the rendering engine of the first graphics processor is in the reduced power state. Accordingly thermal output and power output is reduced with respect to the first graphics processor since it does not do frame generation using its rendering engine, it only uses its display engine to display frames generated by the second graphics processor.
