Thanks for posting.
Quite unusual behavior that you’re experiencing on this system. My hunch would be that there’s an odd glitch relating to the DisplayLink drivers interacting with the built-in graphics drivers on the system.
Uninstalling, running the DisplayLink cleaner, then reinstalling the drivers would be a good first step. (I’d suggest going with 7.7M4 rather than 7.8 to see if things behave differently.)
-Disconnect the USB adapter
-Uninstall DisplayLink Core software from Control Panel->Programs
-Download and run the DisplayLink cleaner tool, found here:
-Once the Cleaner has been run, reboot (even if not prompted to)
-Now download and run 7.7M4, found here:
***Please be on the lookout for any compatibility warnings during installation, and make note of them if they appear***
-Reboot, even if not prompted to
-Once you’re back in Windows, reattach the USB adapter and see if the behavior changes.
If things continue to misbehave as they did previously, please collect a set of system logs using our tool on the following page:
Once you’ve collected the logs please email to email@example.com and we’ll have a look to see what the best steps will be.
