Hi,

I disconnected the external screen from VGP-UPR1 for several weeks without encountering any problem. Today, I reconnected it. Less than one hour later the problem was back. So no doubt that it comes from display link. I noticed that once done, even when disconnected, the problem may occur. I need to reboot or restart display link driver service to get rid of it.

Thanks for any help,

Olivier
