Methods and apparatus to reduce power consumption and improve battery life of display systems using adaptive sync

Abstract

Methods, apparatus, systems and articles of manufacture to reduce power consumption and improve battery life of display systems using adaptive sync are disclosed. An example apparatus includes an interface to transmit frame data to a sink device, the frame data generated by a processor; a timer to initiate in response to the transmission of the frame data to the sink device; and the interface to transmit a low power indication to the sink device after the timer reaches a threshold amount of time.
