Provide a detailed description of the issue
I have just upgraded from Windows 7 to Windows 10. I have updated video driver to different versions, but currently running 10.18.10.4276 and noticed that when I run the
laptop plugged into the dock with an external display, the displays (laptop and external) flash, and sounds like a monitor is connected and disconnected. This occurs randomly, but at least every 20 minutes, sometimes a couple of times in 5 minute. If I plug the monitor into the laptop (external display port) I dont seem to have this issue.
