Abstract
A display controller that permits more than one display to be operated by a single cable and a single display adapter. The display controller provides custom EDID information to a computer to which it is attached. The custom EDID information may include information about the single virtual display surface provided by all displays, and may include information about each of the individual monitors or displays, including the location of the individual displays in the single composite display surface. The single composite display surface may be utilized by computers that are not capable of recognizing the EDID for the multiple display system. If the computer does recognize the EDID for the multiple display system, the operating system of the computer and/or applications running on the computer may understand and utilize the heterogeneous nature of the display surface and may optimize display quality and presentation for a user.
