    I have the Acer H277HK connected via a Thunderbolt3 cable to a late 2017 MacBook Pro. Monitor worked fine right up to the point last Friday when I updated to MacOS 10.13.4. Computer now charges when connected, but monitor stays black and reports 'no connection'. Still, Display settings on my computer recognizes the external monitor. I have seen reports on problems with DisplayLink, but not with 4K monitors. Any known workarounds?
