Abstract: Systems, apparatuses, and methods for implementing kernel software driven color remapping of rendered primary surfaces are disclosed. A system includes at least a general processor, a graphics processor, and a memory. The general processor executes a user-mode application, a user-mode driver, and a kernel-mode driver. A primary surface is rendered on the graphics processor on behalf of the user-mode application. The primary surface is stored in memory locations allocated for the primary surface by the user-mode driver and the kernel-mode driver is notified when the primary surface is ready to be displayed. Rather than displaying the primary surface, the kernel-mode driver causes the pixels of the primary surface to be remapped on the graphics processor using a selected lookup table (LUT) so as to generate a remapped surface which stored in memory locations allocated for the remapped surface by the user-mode driver. Then, the remapped surface is displayed.

Abstract: Methods and apparatus provide a picture-in-picture (PIP) overlay window on a single physical monitor by displaying a first swap chain of the single physical monitor, reporting to an operating system (OS), a display level request for a fake connection to a non-existent second monitor, and displaying on the single physical monitor a virtual display defined by a second swap chain of the non-existent second monitor, as the PIP overlay window on the displayed content of the first swap chain on the single physical monitor.
