Abstract: A non-transitory computer-readable storage medium can include instructions stored thereon that, when executed by at least one processor, are configured to cause a computing device to determine, in response to a change in a refresh rate of a display, an encoded intensity of at least a portion of an image presented by the display, determine that the encoded intensity is within a predetermined range, and based on determining that the encoded intensity is within the predetermined range, adjust an intensity of a signal for the portion of the image.

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.

Abstract: A non-transitory computer-readable storage medium comprising instructions stored thereon. When executed by at least one processor, the instructions can be configured to cause a computing device to, in response to an instruction to transition from a first refresh rate to a second refresh rate, modify a transitional frame. The modifying the transitional frame can include refreshing a first row in a display with a first adjustment to a peak signal of at least one pixel in the first row, and refreshing a second row in the display with a second adjustment to a peak signal of at least one pixel in the second row, the second row being refreshed after the second row, the second adjustment being greater than the first adjustment.
