William,
Indeed, updating to the more recent firmware does provide much finer
adjustments. THANK YOU!
This 6 Axis Color Trim does help.
I'm glad NEC decided to implement this in MultiProfiler.
You think it would be possible to evolve this into a "sector correction"
kind of control?
To limit the effect of the edit only on the base of a*/b* value?
I know I'm probably asking for too much...
BTW, there is a nice animation provided by the RGB cube image displayed in
the main interface: when sliding the 6 Axis controls fully left and fully
right, one can see that part of the RGB cube changing color dynamically.
Best / Roger

You should check the firmware version in your PA series display, as an
update has been released that, amongst other things, improves the
granularity of the 6-axis color controls. The update is available here for
both Mac and Windows:
http://www.nec-display.com/dl/en/dp_soft/pa_fm_update/index.html
The latest versions are 1.01.04 for the PA271W and PA301W, and 1.01.09 for
the PA231W, PA241W and P241W.
