2-19-13+contact+about+color+desaturation

I contacted logmein about having greyscale for the computer I am sitting at. They suggested I contact the manufacturer.

I contacted the graphics card companies for my home desktop HPE-510Y Desktop my laptop Gateway CX210X and my work desktop

The message was kind of like

I would like to desaturate the color on my computer so that everything looks completely greyscale since I find this causes me less eyestrain, especially at night. I actually have a color desaturation option in the catalyst control center. However, when I modify this and click apply absolutely no change is made. Can you help me either: 1. get the Catalyst Control Center to make a change like it is supposed to, 2. find some other software that would allow me to make my screen greyscale (the color is desaturated), or 3. find some 3rd party software that would allow me to make my computer greyscale (the color is desaturated). Thanks for any help and information you can offer me! -- for all of them
