I have a Dell Latitude E6520 laptop, to which I am trying to use a Samsung S22C200 external monitor. The laptop cannot detect the monitor at all. I have tried Fn + F8 to no avail. I have updated the drivers(this is a recently re-imaged box), checked the monitor against another computer(it works), tried different cables(these are all good), and even plugged the computer into a docking station and plugged the monitor into that. Nothing seems to work. It's like the computer is blocking the connection, but there is nothing in Event Viewer that mentions the monitor. Any suggestions?
