Abstract:

Plural information handling systems interface through a KVM switch with a DVI display with the KVM switch supporting selection of the information handling system providing display information to the display. A hotswap switch initiates a hotswap signal to the information handling system that is selected to provide display information to the display. Receipt of the hotswap signal at the information handling system results in the driver of the selected information handling system redetecting the display with a communication through the DDC channel and transfer of EDID information from the display to the selected information handling system so that the selected information handling system drives a desired display port, such as by sending display information through a TDMS channel instead of default VGA channel.
