    Abstract: The techniques of this disclosure include initiating, by a source device associated with a primary display device, a wireless display session with an external display device. Furthermore, the source device may change from a dual update mode to an external-only update mode during the wireless display session. Based on the source device operating in the external-only update mode during the wireless display session, the source device may discontinue generation of the primary stream and may continue generation of the external stream.

    Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine one or more user input events based on user interaction data. The processor is further configured to select a video mode or a command mode as a selected mode, for operating the display processor, using the quantity of touch events. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.

    Abstract: Techniques are provided for optimizing display processing of layers below a dim layer by a display system. Because the dim layer may partially obstruct, conceal, or otherwise impact a user view of layers below the dim layer, resource-saving techniques may be used in the processing the layers below the dim layer. While these techniques may impact visual quality, a user is unlikely to notice visual artifacts or other reductions in quality in the modified layers below the dim layer. For example, when a dim layer is to be displayed, a GPU can render layers below the dim layer at a lower resolution. Furthermore, the GPU can increase a compression ratio for layers below the dim layer. The low-resolution layers can be scaled-up to an original resolution and the compressed layers can be uncompressed in the display pipeline for display underneath the dim layer.

    Abstract: Methods, systems, and devices for refreshing a display of a device are described. A device may identify a type of content to be displayed. For example, the type of content may be associated with a given application. The device may determine, based at least in part on the type of content, a periodicity for a histogram analysis operation for the display. The device may then perform the histogram analysis operation according to the periodicity. For example, the device may compare a histogram for a frame of the content to a scene change threshold according to the periodicity. The device may determine one or more pixel adjustment parameters for the display based at least in part on the histogram analysis operation. The device may display one or more frames on the display based at least in part on the one or more pixel adjustment parameters.

    Abstract: A device includes a display client configured to output pixel data at a display and a processor. The processor is configured to determine a composition of one or more layers for display at the display client. The processor is further configured to select a video mode or a command mode as a selected mode, based on the determined composition. Pixel data for each frame to be displayed is output to the display client when operating in the video mode. Pixel data for frames that include different pixel data for at least one pixel than a previously output frame is output to the display client when operating in the command mode. The processor is further configured to output an instruction to operate in the selected mode.
