best color settings for LG led monitor?

Hi,

I am using my macbook in clamshell mode with my LG 22 inch E2260 LED monitor over DVI and today I learnt that the factory settings for the monitor are not optimum for use with my macbook. perhaps they must have been set for pcs. there was a pink hue in the display. at the moment i'm using these settings...

color temp: sRGB

brightness 100

contrast 70 (grayed out)

sharpness 5

black level low (grayed out)

can u tell me which is the best setting.

in Lion it has been set to automatically choose the color profile for my monitor.
