Error message!! I was going along fine just as you suggested, but it never let me match current values and target values during the calibration process.  Is it supposed to do this, or should yhe calibration process just procede automatically?   Should it just go on it's own, or am I supposed to get this option to compare and adjust?  Regardless, as the calibration goes along on it's own, near the end of the calibration process I got an error which says "The calibrated White Luminance of the display is too high - your adjustmets did not achieve the desired target value.  The calibrated value is 257.6 and the target value is 125.  You should either reduce the White Luminance of the display or increase the White Luminance target value.  If you have enabled Ambient Light compensation, then you need to increase the ambient room light to get a higher target value recommendation."

What do I do? How do I reduce the White Luminance of the display? Should I be adjusting the brightness control either at the beginning or somewhere along the way?
Thanks,
Matthew Kraus
