1. A method comprising:
receiving, by a display controller from a graphics processing unit (GPU), frame data to be displayed at one or more slave displays of a plurality of displays;
receiving, by the display controller, one or more master cycle signals indicative of a display cycle of a master display of the plurality of displays;
synchronizing, based on the one or more master cycle signals, display cycles of the one or more slave displays with the display cycle of the master display; and
in response to determining that blanking periods of the plurality of displays overlap for at least a blackout duration, causing a system operation to be performed during overlapping portions of the blanking periods, wherein the system operation reduces availability of display data to the plurality of displays.
