Abstract: Exemplary embodiments of methods, apparatuses, and systems for seamlessly migrating a user visible display stream sent to a display device from one rendered display stream to another rendered display stream are described. For one embodiment, mirror video display streams are received from both a first graphics processing unit (GPU) and a second GPU, and the video display stream sent to a display device is switched from the video display stream from the first GPU to the video display stream from the second GPU, wherein the switching occurs during a blanking interval for the first GPU that overlaps with a blanking interval for the second GPU.

Abstract translation: 描述了用于将发送到显示设备的用户可视显示流从一个渲染显示流无缝地迁移到另一渲染显示流的方法，设备和系统的示例性实施例。 对于一个实施例，从第一图形处理单元（GPU）和第二GPU两者接收镜像视频显示流，并且将发送到显示设备的视频显示流从来自第一GPU的视频显示流切换到视频显示器 来自所述第二GPU的流，其中所述切换发生在与所述第二GPU的消隐间隔重叠的所述第一GPU的消隐间隔期间。
