Abstract
One embodiment of the present invention sets forth a method for accessing display configuration information of a display device in a multi-graphics-processing-unit (multi-GPU) system based on a hot-plug detection signal associated with the same display device. The method includes the steps of changing the power state of a discrete GPU (dGPU) in the multi-GPU coupled to the display device after having detected an assertion of the hot-plug detection signal, retrieving the display configuration information of the display device with the dGPU, and powering down the dGPU after having retrieved the display configuration information.
