Not pushing display from Surface 2

[bdoub1eu]

This worked yesterday...Today, the software is running (I can see it in the system tray), but it's just not pushing the display to the monitor although everything in the software says that it is...Obviously the monitor has power but just doesn't have display. It's set to auto detect (have tried manually to vga as well).

I've tried restarting the service, rebooting, unplugging the USB dock, etc. Very frustrating...

Support files are attached.
