Abstract: Examples described herein relate to a graphics processing system that includes one or more integrated graphics systems and one or more discrete graphics systems. In some examples, an operating system (OS) or other software supports switching between image display data being provided from either an integrated graphics system or a discrete graphics system by configuring a multiplexer at runtime to output image data to a display. In some examples, a multiplexer is not used and interface supported messages are used to transfer image data from an integrated graphics system to a discrete graphics system and the discrete graphics system generates and outputs image data to a display. In some examples, interface supported messages are used to transfer image data from a discrete graphics system to an integrated graphics system and the integrated graphics system uses an overlay process to generate a composite image for output to a display.

Abstract: Techniques for selective display frame fetching are disclosed. Some example techniques disclosed herein cause at least one processor to at least determine if an indication of a new frame includes an indication of a flip event, and identify one or more dirty regions of the new frame based on the flip event. Disclosed example techniques also cause the at least one processor to fill a display buffer with the one or more dirty regions of the new frame, scan out the one or more dirty regions of the new frame from the display buffer to a display port, and apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Abstract: Examples disclosed herein obtain first image data and the second image data for a foveated image frame to be displayed on a display, the first image data to have a first resolution and the second image data to have a second resolution lower than the first resolution. Disclosed examples also up-sample the second image data based on first metadata to generate up-sampled second image data, the up-sampled second image data to have the first resolution, and combine the first image data and the up-sampled second image data based on second metadata. Disclosed examples further perform, based on third metadata, a combination of at least two different filter operations on an overlap region including a portion of the first image data and a portion of the up-sampled second image data to generate the foveated image frame, the third metadata to specify a width in pixels of the overlap region.

Abstract: Technology for a display device is described. The display device can include at least one display screen operable to show at least one display panel. The display device can include a controller. The controller can receive a content frame from a content source over a transport topology. The controller can receive a presentation timestamp (PTS) associated with the content frame, where the PTS indicates an earliest time at which the content frame is to be displayed at the display device. The controller can provide the content frame for display on the display panel at a subsequent panel refresh opportunity in accordance with the PTS.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can obtain an indication of a new frame and, in response to the indication of the new frame not including an indication of a flip completion event: (i) fill the display buffer with the new frame; (ii) scan out the new frame from the display buffer to a display port; and (iii) apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Abstract: In one embodiment, a new frame is to be presented on a display. A frame time is predicted for the new frame along with a current balance for a set of previously presented frames. A frame pattern for the new frame is determined based on the predicted frame time and the current balance.

Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., non-transitory physical storage media) to implement foveated image rendering for head-mounted displays device are disclosed herein. Example head-mounted display devices disclosed herein include a frame buffer to store first and second image data for an image frame, the first image data having a first resolution and the second image data having a second resolution lower than the first resolution, the first image data and the second image data obtained from a host device via a data interface. Disclosed example head-mounted display devices also include a device controller to up-sample the second image data based on first metadata from the host device to generate up-sampled second image data having the first resolution, and combine the first image data and the up-sampled second image data based on second metadata from the host device to render a foveated image frame on a display.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.
