    Abstract: Display control of a sink device is provided. The sink device has tiles forming a display and is connected to a source device via interfaces. Each interface provides a video stream to a respective tile. The source device includes a policy engine, and a GPU (graphics processing unit). The policy engine obtains link training data provided by the driver of the GPU, including information regarding a negotiated link configuration for the interfaces. The policy engine generates configuration data based on the synchronous link training data, the configuration data including a set of configurations each of which associated with a resolution of the display. The policy engine provides driving data to the GPU derived by mapping a resolution to a configuration implementation on the interfaces based on the synchronous link training data and the configuration data.
