8.2.1 Dual GPU With Docking Station Support

Many consumer devices require multiple video sources to be routed to multiple output sinks. One example of these devices is a dual-GPU laptop with docking station support. The laptop has two video sources that can be chosen: one low-power integrated GPU and one high-power discrete GPU. The video stream from one of these sources needs to be routed to one of two outputs: the docking station port or the laptop DisplayPort video port. In order to support this functionality, a high data rate, multi-input/multi-output switch system is required.
