I am also experiencing this issue. I have isolated the issue to the computer and not docking station as still issues when directly plugged into monitor. The displays work perfectly when computer is left open but once computer is closed then it will start glitching and searching for signal every 2 seconds. I have changed all battery settings to ensure that it isn't a sleep setting issue to no effect. Please help as there were no issues running on Catalina.
