  • Is configuration such as "redcontrast" supported?

    Hi, i am preparing to purchase a HD 4850 card for my desktop. But I do not know if the card allows users to set tiny configuration such as redcontrast or bluebrightness. Since I need to calibrate my LCD for photo editing (very poor I cannot afford physics calibration instruments...) I know that nvidia has such configurations. Or it is still very helpful if anyone can kindly introduce me what configurations the newest driver catalyst affords, in aticonfig command.

    Thank you all.

    Using the binary blob from AMD (currently fglrx 8.54.3), the included amdcccle program does have the ability to adjust RGB levels. The Color tab will allow you to change Red, Green, and Blue values from 0.50 to 3.50, defaulting at 1.00. This appears to be what you are looking for.

    After doing a little searching, I found a console based program called xgamma included with the x11-xserver-utils package that should work with the FOSS drivers if you prefer to use one of them. I'm not going to take the time to test this assumption however...

      i am not a color expert, but thought that an color profile was loaded to xorg, not the driver ( or xorg did it). i did some googling and found http://en.wikipedia.org/wiki/Linux_color_management and http://www.linux.com/articles/113936 perhaps that will help.

        Thank you all~ I thought only RGB-gamma is ok. I just feel confused after I saw some people configured their nvidia-setting with redbrightness and something like that.

        It seems I should learn more about color management


        or simply buy a spyder....

        Thank you again
