Abstract: An information handling system includes a video processor that provides a first video signal in a first video format; a display that receives a second video signal in a second video format; and another display that receives a third video signal in a third video format. The first, second, and third video formats are all different from each other. The information handling system also includes a mid-stream frame buffer that stores video information from the first, second, and third video signals, and a video selector coupled to the mid-stream frame buffer the video processor and the displays. The video selector converts the First video signal into the second and third video signals and couples the video processor to a selected display.

Abstract: A system and method for providing dynamic refresh rates for displays is disclosed. According to one aspect of the disclosure, an information handling system can include a refresh rate processing module coupled to a memory operable to store video display content. The information handling system can further include a display unit operable to display the video display content using a variable refresh rate. The information handling system can further include a refresh rate selector logic coupled to the display unit display. The refresh rate selector logic can be operable to alter the variable refresh rate in response to a content type stored within the memory.

Abstract: A display provides power to an information handling system through a display cable. The display cable includes a power wire and an auxiliary channel. The display and information handling system communicate through the auxiliary channel to coordinate power transfer from the display to the information handling system, such as in the form of a trickle charge to a battery integrated in the information handling system.

Abstract: A system for controlling power to multiple processing cores operating in separate domains in an information handling system (IHS) is provided. The system includes a power regulator that is programmable to output voltage depending on a processor domain and a corresponding performance state. In some instances, one processor may be an integrated graphics processing unit, and another processor may be a discrete graphics processing unit.

Abstract: DVI native and docking station support for a portable information handling system provides output of display information from a either DVI connector at the portable information handling system housing or from a DVI connector at the portable information handling system docking station. A DVO signal outputs from a graphics component to a multiplexer that selectively provides the DVO signal to a TMDS transmitter associated with a housing DVI connector or to a TMDS transmitter associated with a docking station to information handling system connector and docking station DVI connector. Selection of the housing TMDS transmitter to receive the DVO signal is made if the information handling system is not coupled to the docking station, and selection of the docking station TMDS transmitter to receive the DVO signal is made if the information handling system is coupled to the docking station at the docking station connector.

Abstract: PCI Express bus utilization is monitored for one or more predetermined thresholds to adjust the width of the bus in accordance with the utilization to provide power savings with minimal impact on performance. For instance, a performance monitor of a graphics controller tracks bus utilization with registers to adjust bus width between one, eight and sixteen lanes. Reduced numbers of active lanes are used at low utilization, such as one lane when a desktop graphic is presented on the display, increased numbers of active lanes are used at moderate utilization, such as eight lanes when a video image is presented on the display, and all lanes are active at high utilization, such as for presentation of three dimensional images.

Abstract: A portable information handling system (IHS) performance increasing apparatus includes a portable slice chassis that is operable to be coupled to an IHS external to a portable IHS chassis. At least one graphics processing unit is located in the portable slice chassis. The apparatus may be coupled to a portable IHS to provide increased graphics processing power for the portable IHS.

Abstract: A system and method for managing power consumption of an information handling system dynamically switches between high and low clock speed data transfers with double data rate (DDR) memory. The selection of a high clock speed dynamically switches the DDR memory to connect to a parallel termination for more rapid data transfers with increased power consumption. The selection of a low clock speed dynamically switches the DDR memory to disconnect the parallel termination for slower data transfers with reduced power consumption. In one embodiment, portable computer graphics DDR memory reduces power consumption by selecting low clock speed transfers without parallel termination when operating on internal power. The portable computer graphics DDR memory provides improved display resolution by selecting high clock speed transfers with parallel termination when operating on external power or when displaying information from high resolution applications.
