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.
