After mucking around, I only did two things that might have solved it. At first LG Screen Manager saw that my monitos needed an update, would download it, but the monitor would crash when the software was installing. Strange that it still appears in Activity Monitor It's running Catalina. I know that I'm getting data from my Mac to the monitor, and vice versa, On Screen just crashes. Unfortunately, no matter which combination, or order used, as soon as the monitor detects the USB uplink (a flash drive in the back USB hub become available), On Screen Control immediately crashes.
