Color calibration on viewsonic Vx924

hey guys,

i just recently purchasesd viewsonic vx924, and i dont really see the "vibrant colors" from this monitor. As i have done some research and read many reviews, it seems like you gota play with the color settings to get the optimal color out of this lcd.

according the the review by this site, the sRGB mode is not satisficatory

so my question is , do you only change the brightness contrast levels?
or you should also adjust color ( what modes in terms of 5400k, 6500k..etc , or you should manually configure it)?
can anyone provide the settings they are currently using?

my settings are : color mode : 6500k
contrast is about 80% brightness about 60%

thanks all in advance!
