Bug Description
Turns out that Displayport Multi-Stream Transport has not been implemented for Skylake, causing blank screen issues (now that hangs have been fixed..) when plugging external displays to outputs connected to the MST hub. Disabling DP MST allows at least one of the outputs to work, if there are several behind the hub.
