First Claim
Patent Images
1. An information handling system comprising:
- a housing;
components disposed in the housing and operable to cooperate to process information;
a graphics system disposed in the housing and interfaced with the components, the graphics system operable to process the information to generate pixel values for presenting the information as visual images at a display;
a graphics connector interfaced with the graphics system and operable to communicate information from the graphics system to a display cable, the graphics connector having an auxiliary link for communicating management information and plural data links for communicating the pixel values; and
a protocol selection controller interfaced with the graphics system and operable to adapt the protocol used on each of the plural data links based upon one or more predetermined factors.

Abstract
A display cable supports communication of display information and peripheral information between a display and an information handling system by selectively adapting data links of the display cable to include peripheral information. The data links can switch between display information and peripheral information communication or can include identifier information to support switching of both types of information on a common data link.
