Dual monitor resolution problem - dell d620 and dock

Equipment:

Dell Latitude D620 notebook with NVIDIA Quadro NVS 110m (driver is nvidia 7.15.11.144) and running Window 7 Ultimate
Dell D/Dock deluxe docking station with (1) DVI and (1) VGA connection
(2) Westinghouse 22” monitors with DVI and VGA

Goal:

I want to run Westinghouse dual monitors with laptop monitor closed. Both monitors need to run 1680 x 1050 resolution.
I have everything working perfectly except the monitor that is using the DVI connection is currently running at 1024 X 768 resolution and has no option to run at 1680 x 1050.
This combination has worked recently but it somehow reset itself and I can’t get the resolution to change.

Solutions that have failed:

Updating drivers from Dell’s website to the latest and greatest….all updated drivers from nvidia only recognize one monitor….only current version shows both monitors.

Running a video card in the available PCI slot in the docking station. Works but at 1680 x 1050, the mouse becomes sluggish and slows the notebook. Also tried usb / VGA combo with same result.

Any possible solutions would be welcomed.
