Abstract
The described embodiments provide a system that facilitates a switch from using a first graphics-processing unit (GPU) to using a second GPU to drive a display. During operation, upon generation of a request to switch from using the first GPU to using the second GPU as a signal source for driving the display, the system obtains a transform (such as a lookup table) that enables the displayed color output from the second GPU to substantially match the displayed color output from the first GPU. The system then makes the transform available for use by the second GPU in driving the display.
