It's been a while since i was using Nvidia and i don't remember all the sub menus by memory Gary...but, open them up all and check if you can find a setting called overscan/underscan...should be 0.
found nothing overscan/underscan
SCALING
scaling is set to aspect ratio, not to full or no
perform scaling is display not gpu
not overriding
PREVIEW
connection is dvi
current resolution is 1600x900
refresh is 60
native 1920x1080
description--stretches desktop to fit entire screen even is aspect ratio is not the same.
typical usage is make desktop image as large as possible.
These should have all been default setting, other then resolution.
Also reinstalled the display driver and did it as express instead of custom. What I was seeing as the control panel was current.
