I am trying to modify the RGB values and brightness settings of my HP2509b monitor so that the the images on my screen more accurately reflect the prints that I receive from my photo lab.
After I modify the RGB settings so that the White Balance on my screen matches the print pretty closely I then attempt to lower the brightness to adjust that setting more closely to what I see on my print as well. Upon reducing the brightess by only 1 value, my RGB values instantly reset to the 6500K preset.
WHY????
