Dell U2412M Problem : The monitor isn't detecting the signal from laptop

I am using a Dell U2412M monitor connected to my XPS15 through the USB3 docking station.  It has been working for 2 months and stopped working this morning.  I've confirmed that the U2412M drivers are installed by the laptop is unable to detect the monitor.  I tried detaching and reattaching the monitor cables to my dock but it did not result in the laptop recognizing the presence of the monitor.

dkraulis,

As a non-dock test, try connecting the monitor directly to the a port on the XPS 15 via a DP to mDP cable. Is the XPS 15 lid closed when docked?
