Did the recent update break 4k at 60hz?

[David58117]

I have a 2016 non-TB MacBook Pro connected via a Belkin USBC to HDMI adaptor. It's ran at 60hz on a LG 27UD69P-W monitor for a few weeks now perfectly fine.

Until last night, when I did the 10.13.2 update and went to sleep. I woke up and the monitor is showing a black screen. I can get it to work at 30hz, but not 60.

Is anyone else having this problem ?

2013 Mac Pro.

Finally gotten 60hz via MDP to HDMI active adaptor working.

Install 10.13.2 and yes, it breaks for me. Back to 30Hz.
