NVidea driver problem with RC2

I installed Vista RC2 onto a new computer with NVidea 7600 GS card. My
monitor is a 19" widescreen with 1440 X900 resolution. The Nvidia drivers,
both the ones on nvidia's site now and the ones installed by Vista do no pick
up the correct resoltuion for the monitor and I haven't been able to fix it
no matter what. As a result, the display is fuzzy and distorted. (I have a
much better picture on an old Dell with a Nvidia MX4 card that isn't even
officially supported by Vista, though I'm not using the wide screen monitor
on that computer.

Second, when I installed the drivers from NVidia, it did not install the
extra NVidea tools that are usually installed with the card. Info on the
NVidia download page indicated they were included and it was a big download.

Does anyone have any help or advice for me?

Thanks!
