I inadvertently selected the “Turn Off Notebook” option in the System Tray and immediately it turned off my dual Dell monitors on my desktop and transferred my Win7 64bit desktop to the Displaylink monitor. When I tried to select “Extend” the Displaylink monitor disappeared as well. I can still see the mouse pointer on the screen but that’s it. The other two monitors have no video and have gone into standby mode. I unplugged the usb cable feeding the displaylink but the Dell monitors did not come back up. I remoted into the desktop and disabled the displaylink service to regain control. I removed the drivers, down loaded the 15 June version of the drivers and reinstalled. I rebooted and the Dell monitors disappear once Windows drivers take control. During boot up from BIOS the video is on the Dell monitor but as stated goes away after windows takes control.
Why is the Displaylink driver remembering the previous settings even with a clean install?
