@agriffis MST support for the Dell UP2424Q is only required if you want to use the monitor's daisy chaining function.

I thought dp1.2 could drive 4k @60hz
DP 1.2 has enough bandwidth, but the decoder chips (more specifically, the TCON) that are currently on the market are not clocked high enough. So 4K@60Hz monitors need to have an internal DP MST hub still; the monitor uses only one cable, but will be seen as two separate displays by the GPU. This will change once those chips reach the market.
