An apparatus and method is disclosed for providing an extensible information handling system (IHS) bus implemented on predetermined channels of a digital video interface. IHS video signal information is multiplexed with IHS bus information by a host multiplexer for transmission across a digital video connector. The multiplexed IHS video signal and IHS bus information is received by a display multiplexer, where it is demultiplexed. Demultiplexed IHS video signal information is received by a video interface receiver, where it is used to generate an image on a digital display. Demultiplexed IHS bus information is received by a host bus interface transmitter/receiver, where it is used to support peripheral devices attached to the digital display.

System and method for providing PCIE over displayport

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.

System and method for powering an information handling system through a display cable

A method includes determining if a display connection is in an information handling system, reading configuration information from a display, determining whether the configuration information identifies the display as an internal device, and training a data link. A memory includes code to perform a method of determining if a display connection is in an information handling system, reading configuration information from a display, determining if the configuration information identifies the display as an internal device, and training a data link. An information handling system includes a memory with code, a display, and a graphics processor that executes the code. The code operates to determine if a display connection is in the information handling system, read configuration information from the display, determine if the configuration information identifies the display as an internal device, and train a data link.

System and method for authenticating a display panel in an information handling system

A method and apparatus for controlling brightness, color and contrast in CRT monitors used in information handling systems. In accordance with the present invention, a viewing area on a CRT monitor is enhanced by applying appropriate signals directly to the grids in the CRT. In one embodiment of the present invention, appropriate voltage signals are applied to the Ggrid of the CRT. Parameter data is provided to the CRT using a DDC2/CI data channel, with the parameter data being based on the VESA MCCS command set. Utilizing the method and apparatus of the present invention, it is possible to achieve significantly greater brightness, color and contrast control in enhanced viewing areas displayed on a CRT monitor used in an information handling system.

Enhanced brightness, color and contrast control for cathode ray tube monitor

System and method for providing PCIe over displayport

An improved method and apparatus is disclosed for communicating control information between components of an audio/video system. Processing and control logic is implemented to transfer a plurality of data streams on predetermined channels of a digital video interface. A first data stream contains video data received by a video interface receiver, where it is used to generate an image on a digital display. A second data stream contains control data, which is similarly received by the video interface receiver, and is used to control source devices coupled to the digital display.
