    I'm trying to tune my LED with ATI CCC to make it better.

    here is my profile:
    gamma 0.65-0.80
    brightness:-10-10
    contrast:80
    color saturation: 120

    Also I am using Shinew ICC file.

    After tuning I feel better and not TOO WHITE .

    just playing around the graphic card's control panel to see "what looks good" is not a good idea for color calibration. I've never used it but you might want to try this free software based monitor calibration tool -> http://www.hex2bit.com/products/product_mcw.asp

    it won't be as accurate as the hardware solution, but probably better than just eye-balling...

    I don't know if it creates an actual ICC profile or not, but it doesn't really matter. The reason it cannot be used for critical viewing is because fundamentally, you're still eye-balling it :) (more methodical perhaps), and your eyes cannot be trusted as a reference, because there are so many variables that will affect how your eyes perceive color, it includes room lighting, wall & furniture color, time of the day, age, etc... and even your health!

    hardware calibration methods use either a spectrometer or colorimeter to read your computer screen in LAB values(luminosity plus A&B color axis; LAB is an absolute color space). Connected with a USB cable, it is used in conjunction with the supplised calibration software, it then outputs a "profile" that describes the differences between the "red" which your monitor thinks is correct and the real "red", and profiling hardware does it for hundreds or thousands of different color patches displayed on the screen and then interpolate those values into RGB curve, which is then applied to the graphic card's LUT to compensates the display to show the correct color.

    hope this helps.

    Are there any places that do this for a fee? I wouldn't mind dropping a few bucks to get it done rather than buying my own Eye One.

    I know there're services offer printer profiling, it ranges from $25-$100(I've never done it because I do my own). I haven't seen places which do this for laptop yet. One of the main reasons is because you'll need to send in your laptop for profiling, which is not very convenient to do. So it's the best if you have a photographer/designer/illustrator friend who is serious about computer color reproduction.

    If you're in NYC area, i might be able to help.

    I've gotta install my ColorVision software so I can stick my Spyder on this to calibrate it. Curious to see how that goes.
