Graeme,
in particular clipping at the high end seems to be very common among
different LCD display, when the contrast and/or RGB gain controls are
turned up too much. I think it may be helpful for the user, if the
dispcal functions
2) White point (Color temperature, R,G,B, Gain/Contrast)
3) White level (CRT: Gain/Contrast, LCD: Brightness/Backlight)
would give aid to detect a clipped, non-progressive output (e.g. if
dispcal would print a metric for the current amount of highlight
clipping in addition to the current deviation from the target).
Regards,
Gerhard
