i solved it.
i made 2 custom resolutions through nvidias panel and when switching to the other it promps for a test, do the test but dont accept it, let it revert and voila its normal crystal clear pic again :)
looks to me like a software bug either from nvidia or win 7.
searched the internet for hours but couldnt find any answers, although cant set it to use 100hz, it uses 85hz at the moment. cant even force it or anything, it showed in win xp :(
igloola,
Wow, I think you nailed the cure for me.
Win7 via VGA from my Gigabyte nVidia GeForce 9800 GT card


was
sharp at 1920x1080 but fuzzy at 1280x800 (the same 16:10 proportions) on my Dell LCD 1920x1200 . (Vista via VGA from nVidia GeForce Go 7400 in my laptop was sharp on this same monitor.) Besides the fuzzy text, other offered resolutions didn't look quite
right, and when I kept saying 60 Hz (or 75 Hz) they kept reverting back on their own to showing they were using 59 Hz.
So I tried your suggestion and used the nVidia Control Panel (not Win7's Screen Resolution panel) to define a custom resolution at 1280x800 @ 60Hz, and the fuzzy text became sharp. At first it seemed to drop me down to 16 bit color, but I was able to select
the standard-offered 1280x800 at 16-bit and then go back to select my custom-defined 1280x800 at 32-bit.
Thanks ! ! ! You have no idea how many hours I spend searching the internet and dialoging with video card tech support for an answer . . . on second thought, you do know -- you did it yourself first! You're a lifesaver, ... well, at least an eye-saver.
