This is all nice and dandy but there is not even a DP 1.3 MST hub on the market ... Of course, that might be because Intel IGP is still stuck on DP 1.2 and so an overwhelming majority of laptops are DP 1.2 only as well. But for video cards, we have been there for three years now: nVidia went full DP 1.4 with Pascal in 2016 AMD has been DisplayPort 1.4 since Polaris at least in 2016 as well. As an aside, I am unclear whether https://nvidia.custhelp.com/app/answers/detail/a_id/4674/~/graphics-firmware-update-for-displayport-1.3-and-1.4-displays https://nvidia.custhelp.com/app/answers/detail/a_id/4674/~/g... enabled them on most Maxwell cards as well? https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-950/specifications https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-95... still says DP 1.2.
