Claim 4:
5. The method of claim 2, wherein implementing the compensatory VRR scheme includes implementing a frame stretch mode by:
displaying a second frame at the target frame rate for a first frame period, the second frame rendered immediately prior to the first frame;
determining a scan-in delay that is an integer multiple of the PWM period and which represents a delay between scan in of a frame to a frame buffer and scan out of that frame from the frame buffer to the display panel;
responsive to detecting the delay in rendering of the first frame, providing the first frame for display for a second frame period that commences with termination of the first frame period and is equal to a sum of the first frame period and the scan-in delay; and
displaying a third frame at the target frame rate for a third frame period that commences with termination of the second frame period.
