Monitor setup/calibration

[kerm]

Don't know if it's a good art question but recently I played a bit with my monitors and I must say that really alot of how do you see colors and contrast depends from it. I know that I should set up my screens to match the the printing device that I use, but if you draw/paint mainly for digital/internet use... it's not that obvious. Many laptop/tablets screens are really crappy and still, people watch what you drew on them. I really got disappointed when I saw my works on iPad for example... The question is... what's the best setup in your opinion. Or maybe it's the matter of value/color contrast on my artwork, not the screen and I just lack proper skills to ballance those. :)
