I'm not sure if anyone else experiences this but there's a bug in the display settings where:

- high resolution high refresh rate display (max res and refresh rate are higher than DP1.2 bandwidth)

- attached to dock through DP

- macbook lid is closed and plugged into dock

the attached display defaults to the highest resolution, even though it's unsupported by TB3. This leads to a black screen. Changing the resolution by opening the lid doesn't fix this because closing the lid will return the external display to the default resolution.
