Abstract: A system is provided that includes a computing device operable to render video content for display on a display device and to periodically refresh that display device. The video content includes at least one application window. A desktop compositor is operable to wake and execute commands to compose video frames that are composited surfaces that include the at least one application window and to initiate a buffer flip to deliver the video frames to the display device. A high resolution timer is operable to cause the desktop compositor to wake and execute the commands in multiple instances between display refreshes.

Abstract: A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.

Abstract: A graphics processing unit (GPU) instructs a display control module to capture content and display captured content in response to the refresh rate of a display exceeding a frame generation rate of the GPU. Rather than re-transmit the same frame multiple times, the GPU instructs the display control module to replay a previously-transmitted frame. During a refresh cycle in which the display control module is replaying captured content, the GPU omits accessing memory to retrieve and resend the frame that is being replayed, and instead sends only invalid data and GPU timing information so that the display control module remains synchronized with the GPU.

Abstract: Systems, apparatuses, and methods for implementing a single-stream foveal display transport are disclosed. A system includes a transmitter sending an image over a display transport as a sequence of equi-sized rectangles to a receiver coupled to a display. The receiver then scales up the rectangles with different scale factors to cover display areas of different sizes. The pixel density within a rectangular region is uniform and scaling factors can take on integer or non-integer values. The rectilinear grid arrangement of the image results in simplified scaling operations for the display. In another scenario, the image is transmitted as a set of horizontal bands of equal size. Within each band, the same horizontal amount of transmitted pixels are redistributed across multiple rectangular regions of varied scales. The display stream includes embedded information and the horizontal and/or vertical distribution and scaling of rectangular regions, which can be adjusted for each transmitted image.

Abstract: A display system modifies display cycles of one or more displays to perform a system operation while avoiding visual perturbations at the one or more displays. The display system modifies, synchronizes, or both, blanking periods of the one or more displays such that blanking periods equal or exceed a blackout duration and overlap for at least the blackout duration. Then the system performs the system operation during an overlapping portion of the one or more blanking periods, where the system operation reduces availability of display data at the one or more displays.

Abstract: Methods and apparatus provide pixel information for display. In one example, the methods and apparatus map, using a computing device, pixel information of a virtual rendering surface to a physical curved display screen based on field-of-view point reference data and display curvature data of one or more curved displays using a non-constant scale ratio among a plurality of differing physical pixels in at least one row of a portion of the physical curved display screen. Display data is output based on the mapped pixel information for display to the one or more curved displays.

Abstract: A virtualized DisplayPort (DP) configuration data (DPCD) for multi-stream transport (MST) logical DP end points and non-DP end points allows DPCD configuration for links within a DisplayPort topology which are not configurable using DPCD. A virtualized DPCD may configure a link to an internal display of a MST sink device or a non-DP display to receive data using a dynamic refresh rate (DRR), display stream compression (DSC), panel self-refresh (PSR) and other DPCD configurable features.

Abstract: Systems and methods are used to configure a communication channel. A source device can dynamically map Display Port lanes to support both display devices and USB3.0 devices. A method for configuring a communication channel includes detecting a device connection event indicating a change to a configuration of the communication channel in response to a branch device of the communication channel satisfying a dynamic configuration capability criteria indicating that the communication channel is reconfigurable. Configuration parameters of a sink device in the communication channel are identified. The communication channel is reconfigured to carry a source data stream to the sink device based on the configuration parameters.

Abstract: A rendering device signals a display device to capture and replay a current frame to maintain a static image while switching between multiple graphics processing units (GPUs) at a multiplexer (MUX). Replaying the current frame while the MUX switch is in progress smooths the user experience such that no screen blanking or artifacts are observable.
