Abstract
Described herein is a system and method for calculating variable refresh rate (VRR) flicker of a display used for information handling systems. VRR display data is provided to the display which generates a raw optical waveform. The raw optical waveform is captured by an optical sensor. The captured raw optical waveform is weighted using an inverse Fast Fourier Transform from a Temporal Contrast Sensitivity Function (TCSF). Calculating the flicker value of the weighted optical waveform over a defined moving window is performed. The flicker average and flicker maximum of the flicker value is used to determine a VRR flicker value.
