Abstract: Method and apparatus for display image adjustment is described. More particularly, handles associated with polygon vertices of a polygon rendered image are provided as a graphical user interface (GUI). These handles may be selected and moved by a user with a cursor pointing device to adjust a displayed image for keystoning, among other types of distortion. This GUI allows a user to adjust a projected image for position of a projector with respect to imaging surface, as well as for imaging surface contour, where such contour may be at least substantially planar, cylindrical, or spherical and where such contour may comprise multiple imaging surfaces. This advantageously may be done without special optics or special equipment. An original image is used as texture for rendering polygons, where the image is applied to the rendered polygons.

Abstract: Method and apparatus for protecting image content. In an embodiment, tags are used to identify how to alter image content. A graphics processor is configured to process the tags and to alter the image responsive to the tags. In another embodiment, a graphics processor is configured to alter image content unless a key is provided to the graphics processor.

Abstract: Multichip graphics processing subsystems include at least three distinct graphics devices (e.g., expansion cards) coupled to a high-speed bus (e.g., a PCI Express bus) and operable in a distributed rendering mode. One of the graphics devices provides pixel data to a display device, and at least one of the other graphics devices transfers the pixel data it generates to another of the devices via the bus to be displayed. Where the high-speed bus provides data transfer lanes, allocation of lanes among the graphics devices can be optimized.

Abstract: A multiple GPU (graphics processor unit) graphics system is disclosed. The multiple GPU graphics system includes a plurality of GPUs configured to execute graphics instructions from a computer system. A GPU output multiplexer and a controller unit are coupled to the GPUs. The controller unit is configured to control the GPUs and the output multiplexer such that the GPUs cooperatively execute the graphics instructions from the computer system.

Abstract: One embodiment of an edge connector for a field changeable graphics system includes a right angle edge connector having a plurality of contact pins adapted to engage contacts on a graphics card. The edge connector is adapted to interface the graphics card with the motherboard of a computing device, without directly mounting the graphics card to the motherboard. One advantage of the disclosed edge connector is that it is compatible with a plurality of graphics cards and systems, thereby enabling a computing device user to upgrade the existing device's graphics system. Thus, the user is not forced to purchase an entirely new computing device in order to take advantage of graphics innovations. A further advantage of the disclosed edge connector is that it enables upgrades to low voltage differential signaling (LVDS) features, without the need for additional costly devices capable of operating at LVDS data rates.

Abstract: A bus permits the number of active serial data lanes of a data link to be re-negotiated in response to changes in bus bandwidth requirements. In one embodiment, one of the bus interfaces triggers a re-negotiation of link width and places a constraint on link width during the re-negotiation.

Abstract: The present invention provides automatic adjustments to an image presentation based upon changes in ambient light. The adjustments can be made to the back-lighting and/or the pixel data. The ambient lighting can be measured by a variety of sensors (e.g., a digital camera) from a variety of orientations. For example, the sensor can be directed away from the display (e.g., towards the user) or the sensor can be directed towards the display (e.g., from an angle comparable to the users view). In one exemplary implementation a graphics control system utilizes real time ambient light sampling input to calibrate a back-light illumination level and/or pixel illumination levels. The present invention can be implemented in a variety of devices (e.g., laptop, PDA, cell phone, headsup display, etc.).

Abstract: One embodiment of a connector for a stand-alone graphics module is adapted for coupling a computing device to the stand-alone graphics module, which is external to the computing device. The connector is adapted for receiving a PCI express signal from the computing device and for delivering the PCI express signal to the stand-alone graphics module. The connector is further adapted for receiving display output signals from the stand-alone graphics module and delivering the display output signals to the computing system, e.g., for use in accordance with one or more output display panels coupled to said computing device.
