Need help with Color Management and Dell U2711

So i've finally bought a nice IPS monitor with Wide Color Gamut and 100% sRGB and now i want to make sure that all settings are set correct for optimal color reproduction.

I dont know much about Color Profiles, until now i've only tried applying a color profile in Windows 7 - but dont really see a difference.

I've set the monitor for sRGB after reading a few articles that suggest that sRGB is the best mode because everyone who views pictures on the web will experience pictures in sRGB colorspace - and thus what i create, they will see...  - is that correct ?

What i'm now pondering about, is that sRGB feels unsaturated, 100% red doesn't feel red, 100% green doesn't feel green and so is it with Blue and all the colors in between.

This makes me think that something might be wrong ?

If i change profile on the monitor to Standard, Gaming or Multimedia; red, green and blue looks correctly saturated.

Applying color profiles in Windows 7 does NOTHING - i don't see any change at all. I've set the ICC Profile to sRGB IEC61966-2.1 (also tried AdobeRGB) but i dont see a difference between the two.

I dont own an automated color profiler so adjusting the monitor is by hand, on a review of the monitor i've found some settings that should "perfect" the color accuracy - but the setting makes the monitor look dim :-/

any advice or guides i should read ?

thanks - will appreciate any answers i might get.
