Viewsonic 21inch GS815 Best Setting ?

[www.3DGAMEMAN.com]

I have this monitor and was wondering what settings are best for this monitor (convergence, hookings, user color settings, etc.). I know that these setting are personal preferences but would like to get some input. At present it seems a little burry at 1600x1200@95Hz under w2k. Probably a lot to do with my Hercules G2 MX video card. Although it seemed ok on my Samsung 950p 19".
