Old Viewsonic LCD 2001 8 bit dithering

[oneTRICKpony]

Hi there I have an old viewsonic monitor and would like to know the best way to turn down the colors so that the dithering is not noticeable. I have turned down the RGB options in the monitors built in settings and also turned down my windows from 32 bit to 16 bit colors, does this reduce all dithering? It almost looks black and white which is what I am going for.

Is all the dithering gone?

THANKS GUYS AND GALS!
