Problem with text in games

Hi everyone this is my first time on this form so bear with me if this problem has already been answered.
I recently upgraded to windows 7 ultimate 64bit and i find trying to change how my games render text color (Civ111) is very frustrating,the text color isn't sharp and appears blue with a red shadow and I've tried through the nvidia control panel and windows color management to fix the problem so far no luck.
The monitor is an LG E2442-BN led
hope someone can help with this
