I have an HP desktop computer, when adjusting the color it uses a Nvidia control panel which can be found in the Control panel. The color was really messed up to begin with and it took quite a while to get it straightened out. This might be the problem you are having with your Notebook, easy enough to give it a try but don't give up since it takes time to get it right.
