Abstract

Information handling system errors are presented at a display with the information handling system graphics subsystem inoperative by communicating an identified error to the display through an auxiliary channel and generating a presentation of the error information with a microcontroller of the display. For example, errors determined by BIOS firmware running on a chipset are communicated through a DDC or I2C channel from the chipset to the display so that textual error messages are generated at the display without the use of the information handling system's graphic processor to generate an error message image.
