Colour accuracy on your monitor is not a driver issue. You need to "profile" the monitor with a third-party hardware & software profiling utility such as the "Spyder
" range from DataColor.
"Spyder 4 Express
" is their cheapest option. It ensures that your monitor displays the correct colours: http://spyder.datacolor.com/portfolio-view/spyder4express/
I use the previous version (Spyder 3 Express) and it has made a big difference to my colour accuracy when viewing and printing digital photographs.
