Abstract
A method may include measuring, from a device having a display panel configured to operate at a first refresh rate or a second refresh rate, a difference in luminance of the display panel between the first refresh rate and the second refresh rate for an input gray level. The method may also include applying, based on the measured difference in luminance, a value offset to a default gamma value used by the device for the input gray level when the display panel is operating at the second refresh rate, thereby generating a new gamma value. The method may further include storing, at the device, the new gamma value, where subsequent to the storing, the device is configured to override the default gamma value for the input gray level with the new gamma value when the display panel is operating at the second refresh rate.
