Abstract
A method may include executing basic input/output system (BIOS) instructions to initialize an information handling system. The initialization may include generating a hot-plug detect (HPD) override request. The method may further include receiving the HPD override request at a general purpose input/output (GPIO) device. In response to receiving the HPD override request, the GPIO may assert an active-low signal at an interconnect electrically connected to a HPD terminal of a graphics display receptacle, the receptacle for coupling a graphics processing unit to a graphics display device.
