No display attached, but shows up in Windows

Hello Johnny,

I can understand it's a bit peculiar and annoying.
Would you please be able to send me the logs as described in my signature?

Maybe the hotplug circuitry in the dock is defective and therefore telling the computer there is a monitor when there isn't.
Then, Windows restores the layout based on the monitor identification... but as there isn't a monitor connected, it cannot restore what you have saved as it doesn't exist.
(Monitor layout is saved by Windows in the registry keys described: http://support.displaylink.com/knowl...rticles/736116)

Kind regards,
Alban
