Abstract
Systems and methods include an electronic device having multiple GPUs and a GPU power control process that controls switching between a first GPU and a second GPU, such as a high performance GPU. The electronic device may be coupled to an external display by a passive adapter or an active adapter. The GPU power control process may determine if the second GPU is active and switch to the second GPU upon connection of the external display through either the passive adapter or the active adapter. Upon connection of an active adapter, the GPU power control process may use hot plug functionality to determine connection of the external display to the active adapter and provide appropriate switching in response thereto.
