Abstract
Embodiments of the present disclosure provide techniques for identifying a display when a graphics processing unit (GPU) connected to the display via a display control bus is in a low power state. By providing a separate microcontroller with a parallel connection to the display control bus, the microcontroller may detect the presence of a display device even when the GPU is in the low power state. In response to detecting the display device, the microcontroller may notify a motherboard chipset (e.g., via an interrupt) prompting the motherboard chipset to initiate a sequence to bring the GPU out of the low power state.
