These DP splitters don't use any thunderbolt features, so the thunderbolt ports are only used as "simple" DisplayPort ports in these cases. So no actual PCIe transmission in muxed. Still, it would be great if somebody could verify that Thunderbolt ports work (with the full SW stack) just as well as normal DisplayPort ports do. Thank you: Kristof
