I can't get my LG ULTRAFINE DISPLAY 5K to work with my MacBook Pro (15" 2017)
I've downloaded the LG Screen Manager from the Apple Mac store -- when I run the application it says "it does not recognize the external monitor'
I've updated the Mac OS to Catalina yesterday and re-downloaded LG Screen Manager App and still no luck
Any help/advice friends?
Grant -- thank you for the swifty reply
I got the issue resolved by snooping around on tech sites
The issue was bizarre I discovered. We could not figure out why both our LG screens (4 and 5K) worked before but then the 5K stopped dead/black screen -- turns out we moved our Wireless Router to the office yesterday and THAT was the only difference and it happens to be the problem/solution --THE LG ULTRAFINE DISPLAY 5K WILL NOT WORK IF IT IS IN CLOSE PROXIMITY TO A WIRELESS ROUTER! See really helpful article below

So problem solved but man it was an epic puzzle to uncover what was going on (called AppleCare multiple times) -- so simple a solution but so bizzarro a problem (apparently there is a part in the LG that is affected by wireless radiation -- hardware issue not a software fix)

It's really interesting to read that the DISPLAY won't work when too close to the Router, because there was a warning when that display was issued that the display could knock your Router off the air:
.
Ah, thanks -- I did not realize that warning existed: i guess we rushed the purchase and did not do our research.
I've now noticed this afternoon that when I stream YouTube on my MacBook, the LG monitor glitches a lot and goes to black screen for a few seconds intermittently. Once I quit out of Chrome/YouTube, it seems to settle back to normal with no issues
This Monitor just does not seem to like the Router...!
The monitor itself is actually good value and has a v good resolution for the work we are doing -- I just never expected to have these issues with hardware and a router

If you are close enough to the Router to get interference, consider using an Ethernet connection, and wave goodbye to trouble in both directions. Gigabit Ethernet will be faster than almost any Wi-Fi.
