Abstract:
Briefly, methods and apparatus to provide image content to, and display image content on, variable refresh rate displays with reduced input lag. The methods and apparatus allow for image tearing, or the displaying of image content from more than one video frame, when the render rate of a provided video frame falls outside the display refresh rate range of a variable refresh rate display when the display is refreshing with a previous frame (e.g. the display is in active refresh), thus reducing the input lag of the content of the provided video frame. The methods and apparatus may also prevent image tearing when the render rate of provided video frames is within the display refresh rate range of a display.
