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.

The latest version of NEC MultiProfiler, v1.1.0, under the Edit... button,
offers what's called a new "6 Axis Color trim" function. It may not be all
that new for some of you but it is for me. The design of this new function
seems like a winner but it seems overly *sensitive*?
If you have seen the interface then you know what I'm talking about but for
those who haven't, here's what happens...
On the "Hue" control, for instance, are horizontal sliders for the RGBCMY
colors. Fair enough. I suspect these must be implementing some kind of
hardware linear adjustments in the monitor LUTs?
Each slider is implemented with a plus or minus "63" numeric range. The
default value is 0, of course. The number 63 suggests to me that, perhaps,
the control is implemented with 6 bits registers? 2 to the 6 power gives 64,
after all. It may be what it is?
If that's the case then the fix could be a matter of implementing "more
bits" or distributing the available bits differently to make things
smoother?
It's a fantastic step in the right direction, in my opinion but the lack of
bits seems like a hindrance...
To give you an idea of the current implementation's sensitivity, a mere -1
Red move, for instance, results in an overly huge color move. Something like
a 10 delta E, if I was to put in on a perceptual scale. It's in the right
direction all right but it needs more precision, in my view. For the job at
hand, maybe a -0.3 or -0.4 move would be more than adequate, you see?
Some of you may rightfully suggest a White Point move instead. Yeah. I got
that. Thank you. But I already edited the White Point to my heart's content
and I got the grays where I need them to be. If possible, I'd like to affect
the rendering of saturated tones selectively, just like the 6 Axis Color
Trim is designed to offer, I'm sure.
Anyone tried this at home? Know something I maybe be missing?
So far, nothing under Preferences related to this option.
