Abstract: To manage dynamic adjustment of the refresh rate of a computer display, the operating system defines at least two playback modes: one or more custom modes that can be selected by applications, and a standard mode which is a default setting for the system that can be expected by applications. The operating system provides an application programming interface that enables an application to request using a custom mode. If approved to use the custom mode, then the application presents frames for display based on the custom mode. The operating system stores timing data for each buffered frame indicating how to play the frame in both standard mode and the custom mode. If a transition back to the standard mode occurs, the operating system uses the timing data to properly present frames of video until the application stops generating frames of video in the custom mode.

Abstract: Transitions between monitor configurations may be streamlined by minimizing the tearing down and recreating of render targets and primary frame buffers associated with the monitors. In at least one example, the techniques described herein include identifying at least one render target in a first monitor configuration that is also in a second monitor configuration. In response to identifying the at least one render target in the first monitor configuration that is also in the second monitor configuration, the techniques herein describe maintaining the at least one render target during a transition between the first monitor configuration to second monitor configuration.

Abstract: Systems and methods for rebootless updating of a IHV display driver are disclosed. According to such a method, first, the operating system stops the driver from running. Second, the system switches over to an interim or temporary display driver, which be a default driver provided with the operating system. Third, the new hardware-specific driver is started. Thus, a hardware-specific display driver may be updated without rebooting.

Abstract: Resources of a video presenting network having plural outputs can be configured. A provisional configuration can be supported. Configuration of inputs can be performed separately from configuration of outputs. Interdependencies between network resources can be considered to restrict provided options to those co-functional with a provisional configuration. Responsibility for considering interdependencies can be delegated to a video driver, such as a video miniport. A client can use a variety of approaches to find a desired configuration. A variety of configuration goals (e.g., optimal configurations) can be achieved in light of the interdependencies.

Configuration of inputs can be performed separately from configuration of outputs. Interdependencies between network resources can be considered to restrict provided options to those co-functional with a provisional configuration. A client can use a set of functions provided by a service to traverse the configuration solution space. The functions can support a transactional configuration approach. Responsibility for considering interdependencies can be delegated to a video driver, such as a video miniport.

Abstract: A system for using computer input devices with software applications is disclosed. The system includes an input device mapper API, which uses a language of semantics as an interface between input devices and software applications. The input device mapper receives information about which semantics the devices connected to the computer are able to implement, and which semantics correspond to actions that a user can request the software to perform. The input device mapper maps controls on the available devices into user-requestable software actions by matching, as closely as possible, device controls and software actions that correspond to the same semantic. The system thus makes input devices and software applications transparent to each other, and permits a software application to be designed to operate without regard to which input device is being used to control its actions.
