Abstract: Various systems and methods for managing graphics subsystems are described herein. A system for managing graphics subsystems of a compute device includes a display controller operable to: receive an indication that a first display of the compute device has been activated; enable a power management feature in a display controller, the power management feature to reduce power consumption of the display controller and associated components, and the power management feature to reduce graphics memory bandwidth usage; receive an indication that a second display has been activated with the first display; and maintain the power management feature for at least the first display.
