Help with Samsung 2232BW and Nvidia NVS 140M

Hi All, I am new to these forums and had a question that someone could hopefully help me with since I seem to have exhausted all my options.

I have a Samsung SyncMaster 2232BW 22" monitor that I recently started using. I plugged into my Lenovo T61 laptop running a Nvidia NVS 140M. I plugged in and it worked perfectly at the Monitor resolution of 1680x1050 (which IS supported by my video card)

However when adjusting the settings of my monitor i pressed the auto adjust button by mistake. This caused my monitor to "zoom in" slightly rendering slightly pixelated text. Subsequently the tops and edges of my browser window to be cut off. (When adjusting my LCD resolution to my laptop screen resolution 1440x900 this does not happen)

I have tried reinstalling monitor drivers, refresh rate etc but to no avail. Any help would be greatly appreciated.

Thanks
