SpectraView II matrices for wide gamut monitors?

[WillH]

I see the software is called MultiProfiler and controls the SpectraView Engine, which does this automatic tracking ( http://www.necdisplay.com/MultiProfiler/ ).

It allows for internal "resetting/recalibration" of this self-calibration process?

A future version of SpectraView will allow you to use your sensor values to update the internal factory measurements if desired, but this will really only have an impact when used together with MultiProfiler. The reason being that SpectraView calibrates to the sensor values each time anyway. MultiProfiler uses the very accurate factory measurements for each individual display, combined with internal monitoring to achieve very good results without the need for an external sensor or calibration package.

Take it off the list. Its no longer manufactured.

Sorry but, as I've wrote previously, Quato (a German company that produce high end display) is actually selling the DTP94 with its calibration software. It's called iColor.

Here's an interesting Whitepaper:

This is just a snippet:
Colorimeter support for Wide Gamut units
A wide color gamut unit forces the user to have an expensive and limited precision Spectrophotometer, but Quato has found a way to make use of the highly precise DTP94 colorimeter by uploading a correction table into the device. Now users can benefit from the much higher precision of the colorimeter (compared to the Spectro) and save a lot of money.

Thank you for this information.

Is there a time line set for this update of SpectraView, the software?

IMHO you are being extremely rude and condescending. I followed this thread and am wondering whether your are not able to listen or read. Please stop the pollution now, both.

Being rude and condescending certainly wasn't my intent, no more than it was your intent by telling someone they can't read or listen.  Like you I was doing my very best to get a message across, to help someone.  I failed.  Of that there can be no misunderstanding.

In connection to the SpectraView software, I would still think that NEC's own updated, modified or corrected is a better match, than the maybe in general terms better DTP94b!?

I didn’t say it wasn’t being sold, I said its not being manufactured. Its an unsupported X-rite product. Its a great instrument but beware that how much support (think replacement or fixes) you’ll get puts this in a iffy position.

Yes!

There is a little difference between you and me, you are aggressive and I defend.

[shayaweiss]

Yes!

Also, I don't know if this point is relevant, but the Quato puck is the DTP94 and not the DTP94b, which, if I am not mistaken is the acclaimed one. I have a DTP94b and it does indeed perform marvelously well on all our standard monitors. Even on the very cheap LG227w wide gamut monitor, when used with software correction (Quato), or on the laptops here, which I had to recalibrate today. It was sold to me as "EIZO DTP94b", though it does not say EIZO anywhere on it. And it looks different than the DTP94.

After everything that was discussed and quoted about correction filters and matrices for wide gamut monitors - and only one person disagreeing without real arguments -, I don't understand how  it is possible that x-rite does not incorporate such an optional correction in their software?

You may mean hardware. That’s really where these filter matrices need to live.

And with iColor with do see it's feasible...

When asked the same question, about why not integrate a correction into Argyll, Graeme Gill answerd the following:

Currently the instruments are assumed to provide correct XYZ values.
Generally you get what you pay for in this regard. Some colorimeters
don't work so well on some displays, and this is a good reason for
buying a spectrometer.

While it's perfectly possible to create correction matrices for particular
display/colorimeter combinations, in practice there are stumbling blocks.

A major one is that it's a combinatorial explosion. I don't even have
access to all the displays that support in-display Luts, never mind the
thousands
of other LCD displays out there, so I can't supply such correction
matrices. (I suspect it would be a full time job keeping up with them,
even if one were suppled monitors by all the manufacturers). The other
problem is that one particular instance of a colorimeter doesn't necessarily
represent the average for that type of instrument. One needs access to a
statistically significant number of instruments to overcome this problem.

[A systematized solution would involve the display manufacturers publishing
 the spectral characteristics of their displays in a standard format, and
 having some means of measuring the spectral sensitivities of the instruments.]

The profiling is not affected. Shortcuts taken by the colorimeter makers
do affect their accuracy though.

Which makes you wonder about iColor no?

[shayaweiss]

You mean like NEC does with the i1d2 puck?

Would it disturb when used with a non wide gamut monitor?

[shayaweiss]

Which makes you wonder about iColor no?

Exactly, that was my next silly question.

[digitaldog]

But in this case, the filters ARE mated to the display. Its not some correction happening in software, based on some assumption of the display(s). If not, why would NEC go to the trouble if they could just pop this into SpectraView software. Not cheap having a pile of custom built EyeOne Displays OEM’ed. FWIW, if you look back at Barco, PressView and Artisan, they too used custom mated filters for old, sRGB like CRTs. They did it for a reason.

trying to sum up:

So, with wide gamut monitors, one should only use the custom mated puck (or a spectrometer, although some people don't recommend the latter for displays). According to what we came up with here,  if one needs calibration with a device for a wide gamut monitor, one should use a monitor for which there is such a custom mated puck. Also it should be able to be used with the propitiatory software, that can talk to the puck and the monitor.    

In the case of the new NEC PA series, as mentioned, because of the new Profiler software, the need for a puck might be less. As we have heard here, an update of SpectraView is apparently underway. It will supposedly allow recalibration of the self-calibration process of the PA's, via a measurement device, again the NEC corrected puck will be preferable.

You don’t have to but if you have no instrument, by all means if given the opportunity, get a mated colorimeter.

You can buy a suit off the rack or have one custom tailored. Its not like the suit off the rack is akin to walking the streets naked.

[shayaweiss]

You don’t have to

let me seize this opportunity to try to clear something up, which was a matter of wonder for some of us:

We concluded, just now, that a custom mated puck is preferable, right?

How can we understand that NEC lists almost all existing colorimeters, which are not corrected, as compatible with SpectraViewII and wide gamut monitors?

The only explanation, which is very weak, I agree with Steve Weldon, is that, like you said you don't have to, but its better to get the custom tailored one, if you can?!

I am happy to see that you have the same explanation.

Anyone?
