Patent ID: 10990550

Abstract:
In some examples, a logic device may be connected to: (i) a ThunderBolt (TBT) output of a CPU that lacks a DisplayPort (DP) input and (ii) a DP output of a GPU. The logic device may determine a presence of a video signal, e.g., either: (1) TBT video from the CPU or (2) DP video from the GPU. The logic device may re-time the video signal to create re-timed video and output the re-timed video using a USB-C port. If the logic device determines that the video signal is DP, then the logic device may select a DisplayPort Alternate Mode of the USB-C port and output the re-timed video signal using four differential pairs of the USB-C port. If the logic device determines that the video signal is TBT, then the logic device may output the re-timed video signal using two differential pairs of the USB-C port.
