i've recently adjusted my lcd rptv's grayscale using colorvision's spyder pro colorimeter. i entered custom values for x,y to obtain a grayscale value as close to D65 as possible. i proceeded to adjust my cuts & drives along the entire grayscale ramp (from 20 IRE up to 100 IRE). according to the spyder colorimeter results, i was incredibly close to my desired grayscale temperature. here is my issue, when viewing black & white movies, i noticed that there was a red hue to the picture. what should i do to remove this? if i reconnect my colorimeter & take a reading, it is still going to be close to D65 as i haven't changed anything. any suggestions as to how i should correct this? thanks so much guys.
