It is incredibly hard trying to get a screen at the wrong temperature calibrated! 

So, I spent about an hour tweaking the gamma, brightness and contrast for R, G and B channels. Its not the best job in the world, but Norman Koren's Gamma Chart looks pretty good and his Black Level Chart shows I have removed the bad color cast I had before. 

While these results would appear promising, I'm not sure I believe that the changes have done much for me. Now anything that is supposed to be white on screen has a definite blue color cast that won't go away no matter how long I stare at the monitor. 

Does anyone have any sage advice, or suggestions for a forum better suited to these issues? Thanks in advance!
