i am using Nvidia 9600GT on my HTPC in lounge, connected to my panasonic full hd plasma. recently i updated my drivers to v190.62 and my scalling went all wrong. the task bar and icons on left were all hidden. before the update i remember i resized my desktop for everything to fit and it was good. i.e 1:1 pixel mapped.

my tv and htpc connected vida dvi to hdmi cable.

help please.
