I use the same Twin Turbo on the LaCie-D2 (Mitsu of course). I could up the

I run the red gain at 100% so I have the maximum output available from
that display. I bring down the contrast to set the luminance level. This
give me more headroom to dial in my target luminance level without shifting
the white point much.
If you tweak the red gun the other two (green and blue) will change. So
its a back and forth operation to dial in you luminance level AND white
point at the same time. It seems easier to me to nail the white point and
then adjust the luminance level with the contrast then to do both at the
same time. Doesn't mater which approach you use as long as you are
consistent. Take care.
