Andrew, I'm interested in results - how they achieve them inside the code is their business. I'm happy that you're happy that I'm happy! :-)   OK?

Cheers.
OK. I'll stick to my recommendation for SpectraView owners to purchase the software specifically designed for it; no matter where the code is written.

As NEC is using BasicColor software in Europe, I could only surmise that between the two companies they have tested it all for proper DDC compliance and it works - hard to sell a display as a "Reference" model (and charge more money for it) if they haven't. Regardless of all that, the proof of the pudding is in the tasting. I've tasted both and I kept BasicColor. Just somewhat better in my experience, and BTW, very useful operating instructions.
I seem to recall a couple of European based folks on LuLa saying they are using Spectraview now.  Perhaps NEC is selling it in Europe these days.

And there's this:

SpectraView II performs better with PAxx2 series than SpectraView Profiler - it makes better use of internal SpectraView engine and has more precise spectral calibration for X-Rite i1Display Pro and NEC SpectraSensor Pro.

And...
http://forum.luminous-landscape.com/index.php?topic=75804.new;topicseen#new

The SV II software is not available internationally unfortunately. It is reasonably basic in settings and features but does a good job nevertheless. You can see information about SV II from our review of the PA271-SV

2) SpectraView Profiler - This is NEC Europe's equivalent software, based around the popular and high end BasICColor Display software package. It is supposedly designed in this way for the "more demanding" European audience and has a larger range of settings and features than SV II. In Europe there are also two versions of the screen, the regular PA241W and the PA241W-SV (sometimes also referred to as the SpectraView Reference 241). The complication comes with these two varieties in Europe. The regular PA241W has an additional firmware lock which means it cannot be used with SpectraView Profiler to hardware calibrate the screen. Therefore you are limited to software calibration in most cases. Interesting the USA SpectraView II software could work with this screen as it does not care about the firmware lock, but there are issues with availability of that software in Europe.

The NEC PA241W-SV edition does not carry this firmware lock. According to NEC they also offer hand picked and factory optimised panels and so supposedly offer that slightly higher level of accuracy in addition to the regular PA241W. Because the PA241W-SV is no firmware locked, it can be used with the SpectraView Profiler for full hardware level calibration. Again, it could work with SV II as well technically.'

Andrew, this is the post that I was referring to:  http://forum.luminous-landscape.com/index.php?topic=121665.msg1012460#msg1012460   I guess NEC now has released Spectraview II in the EU.

One computer licensing is a deal breaker for me at $119

yes as it was for me too- they use the computer serial to do that.
So you cannot use it again on a laptop screen + main screen...

Yes and yes from primary sources of information; I don't need to compare code and couldn't do so if I were asked.

Question to you: Have you used BasicColor Display 4 or Display 5? If so, what were your findings?

I use both - SpectraView II is better, as it’s the only one that uses custom i1D3 spectral calibration for PA series backlight, and full potential of SpectraView engine. It’s also faster, more convenient, better integrated with excellent MultiProfiler, more stable, and it works with many other, affordable NEC displays (like very good EAxx5WMi series)

Marcin, could you please unpack this a bit and explain:

  • What is the significance of i1D3 spectral calibration?
    "Full potential of SpectraView engine"?
    advantage of "better integrated with excellent MultiProfiler" (why does one need multiprofiler as well)?

Also, does this version of Spectraview software make matrix or LUT profiles?

PAxx2 has GBr LED type backlight - green and blue LED with red phosphor. The brightness of G and B LED is controlled independently by display processor, which is called "SpectraView Engine". Problem is that SpectraView/basICColor Profiler doesn't make use of SpectraView engine, and it uses display LUT instead of G an B LED brightness balance to achieve the target white point. It also doens't use PAxx2 specific spectral calibration for i1D3, but the generic X-Rite calibrations, so there's slightly bigger error in comparison to lab grade 5nm FWHM spectroradiometer, than in case of custom spectral calibration, where there's virtually no noticable difference to reference sensor (see my evaluation: http://forum.luminous-landscape.com/index.php?topic=103094.msg1004707#msg1004707 ).

NEC uses internal 14(16) bit 17x17x17 3DLUT, so it's not reasonable to use LUT-type profile characterisation (you only get worse tonal transitions).

MultiProfiler allows you to apply metameric correction (to get better match between different backlight type displays), tweak calibration visually, or use hardware softproofig, which I find very useful, as it works in every enviroment (no matter if color managed or not), on whole screen surface, with both RGB and CMYK type output profiles without using CPU computing resources. For example - when you want to prepare photobook in Lightroom you can't use CMYK output profile of digital presses, as (due to stupid Adobe policy) Lightroom doesn't support CMYK profiles at all. The internal hardware softproofing of NEC display may be a good workaround in such cases.

Straight from NEC about the rather important SpectraView engine! And yeah, you want all this stuff  :P



SpectraView Engine is the “brains” of the display.
In short it does:
1.       Uniformity correction
2.       Aging compensation
3.       Temperature compensation
4.       Orientation compensation
5.       3x 1D LUTs
6.       3D LUTs
7.       Color gamut mapping
8.       Gamma correction
9.       Black level correction
10.   Ambient light measurement and compensation
11.   Backlight luminance measurement and stabilization
12.   Picture-in-Picture / Picture-by-Picture
13.   Color blindness simulation
14.   Metamerism correction
15.   Hue/Saturation/Offset adjustment

It doesn't use some or all of the SpectraView engine?

I'm not sure, but apparently it doesn't use G and B LED brightness balance, which results in worse CR after calibration (PA calibrated by SVII has virtually stable CR in 5000-6500K range).

It is now OS X 10.13.2 compliant

I think I mentioned this earlier in November here on LuLa.  Anyway, I contacted support again to see if there was any change since the end of October.  I got the same old response.  I'm not holding my breath for a software update anytime soon.

This is out of date information, there has been a policy change.  I am in UK and have used NEC SpectraviewII software to calibrate my PA241W and P242W for at least the last 6 months.  This is my current version: Version 1.1.34.00 - build 170331 - March 31 2017
