Dell D630, when docked,  screen black after boots into Windows 7 Ultimate

Operating a Dell  D630 (8 GB Memory, 1 TB hard drive) with Windows 7 Ultimate.
When undocked , the laptop screen functions normally.
When docked and using a VGA monitor, after Windows 7 logon, the monitor screen goes black (but active).
Same condition as above but boot in safe mode, and laptop & monitor functions normally.

Is this a windows problem or a docked Dell problem?
Is there a solution?

This started after I undocked a operating laptop and tried to connect to an external RGB (not through dock) at another site.
No signal recognized on RGB monitor.
After shutdown and return home, placed in dock, booted, and unable to see anything on home monitor.

Suggestions/solutions greatly appreciated.

This would appear the this monitor, connection or some other occurrence at that time damaged the video output circuit which is the same circuit the dock uses. That is why both do not work.

You will need to get the machine serviced because the video connection circuitry is part of the motherboard in most laptops.

Thank you.
Follow-up question:
If that was solely true, would not the docked laptop with monitor not work in "safe mode" when docked?
I can live without the external monitor circuit when not docked.

As for the undocked video monitor output, I'll see about getting Dell to check it out.

You should be able to set the display to laptop only . That should work depending on the dock characteristics.
