    Abstract: Systems, methods, and non-transitory media are provided for dynamically switching frame rates without changing a display refresh rate. An example method can include receiving, from a display device associated with a computing device, a set of control signals indicating a display refresh rate implemented by the display device; adjusting a frame rate associated with application data from one or more applications executed on the computing device; synchronizing, based on the set of control signals, the adjusted frame rate with two or more display refresh cycles, each display refresh cycle being based on the display refresh rate; providing, to the display device, a first frame at the adjusted frame rate, the first frame being generated based on the application data; and displaying the first frame at the display device implementing the display refresh rate.

    Abstract: Method and apparatus for selecting a gamma curve used by a display driver circuit for converting code words provided by a display processing unit to brightness levels based on an operating mode of the computing device. For example, the display processing unit provides code words to the display driver circuit for driving output at a display. Further, the display driver circuit converts the provided code words to analog signal for driving output at the display based on the selected gamma curve.

    Abstract: Methods and apparatus for graphics processing, such as producing a smooth transition between images of different dynamic ranges (e.g., Standard Dynamic Range (SDR) images and High Dynamic Range (HDR) images). An example method generally includes using a high frame rate during a transition period to allow properties of images to incrementally vary. The properties may include brightness (i.e., luminance), color gamut, tone mapping, among others. For example, during the transition period, a subset of HDR images are displayed at a second frame rate (e.g., 120 Hz) higher than a frame rate based on the HDR images (e.g., 30 Hz). Simultaneously, a brightness level (as well as other aspects) of the display panel is adjusted incrementally from an SDR brightness level to an HDR brightness level during the transition time period over the subset of the HDR images.

    Abstract: In general, aspects disclosed herein provide techniques for processing video data. Certain aspects provide a method for processing video data comprising a plurality of frames for display on a display as discussed herein. The method includes determining a sampling rate (N) based on a frame rate used for displaying the video data on the display. The sampling rate N is greater than 1. The method further includes, for every N frames of the plurality of frames, processing one or more statistics associated with a frame determine one or more display settings. The method further includes outputting to the display the corresponding N frames of the plurality of frames using the one or more display settings.

    Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for reducing gamut mapping luminance loss. A gain value of at least one primary color may be reduced in a native color gamut based on an analog technique (e.g., using a DDIC in a display panel) to provide a reduced color gamut that is smaller than the native color gamut. The reduced color gamut may have a same luminance as the native color gamut. One or more colors included in the native color gamut may be mapped via a digital technique (e.g., using a DPU or other processor) to the reduced color gamut. The mapping may be configured to provide a threshold level of color accuracy in the reduced color gamut.
