I can't believe this idea of 10 bit LUT in monitor is finally becoming
mainstream when this idea was introduced, oh, let me see, when SGI first
introduced its large 23" ACD-like LCD display way back, when, in 1997? Or
was it before? You know, they were even offering its own colorimeter. It was
so innovative then. But, if memory serves, I think they were offering it
with a PC solution for the graphic arts. Maybe that's why it did not caught
on.
