LCD color problems.

Ok I have a problem, or it could be just me. I've recently purchased a new 17" LCD a Sony SDM-HX73 connected to my card with a DVI-I input.

At first everything seemed normal, but as I begin to use it day to day and started surfing many different websites playing games etc, the colors don't seem to be right, some grays turn out to be too blue, and some visual styles don't display properly, for example Azure a visual style looked fine on my old crt but my new lcd it seem to have a slightly different color, also some websites are really dark and hard to read and if I improve the brightness a littlebit other light websites seems too light and washed out, maybe I should have a certain rgb value set up? right now it's R:123 G:123 B:109 , I tried to find tools to help me set the colors up properly but couldn't find anything, any help would be great guys.
