I'm wondering, whether it is an option in this case to turn the britghtness as much down, so that the even the channel with the brightest black level stops emitting light, and to let the calibration curves apply (possibly different, and positive) black offsets for each channel in order to achieve a proper black level and chromaticity? Graeme, is this supported by dispcal? Regards, Gerhard
