macOS High Sierra 10.13.3 Supplemental Update - Apple Display Problem

I were using Apple Cinema 23" with my macbook pro 17", but now, Apple cinema does not work after installed the last High Sierra update (macOS High Sierra 10.13.3 Supplemental Update).

I did not change any connection, just installed updated and display did not work.

MacBook Pro, macOS High Sierra (10.13.3), Apple Cinema 23"

@mhmt190 - how did you solve this issue? I'm having the same problem - after update, one of my thunderbolt ports stopped working. I can connect external monitor to one of them and when connecting to the second one, the display stays "dark"

EDIT:

I had to disconnect the monitor, reboot my Mac twice and once it started, both ports started to work again...
