X1 Yoga 2nd Gen poor color on external monitor

Connecting the sleeping X1 to a dock (Lenovo Thunderbold 3 dock) and then waking it up (lid closed) gives bad colorors and contrast on the external monitor connected to the dock. Restarting the X1 connected to the dock gives normal colors and contrast on the same external monitor. System is W10Pro 1709 64-bit.

Any ideas or help?
