    I currently have a 2nd Dell monitor hooked up to my T400, it has been working perfectly. But a couple days ago it just stopped working, the monitor is sensing its plugged in, but it is just black. I dont know what is going on, help would be greatly appericated. Thanks

    Are you toggling through the different display options with Fn+F7? Once in a while my default seems to randomly change and it goes from extend (default) to one of the other options.

    Have you tried the monitor with another computer? Have you checked the display properties under Windows? Tried reinstalling graphics drivers? I'm just grasping at straws, but its what I would try.
