Spectraview II, Wide Gamut, and Colorimeters
« on: May 27, 2009, 11:59:42 pm »

I have a NEC LCD2690Wuxi that I am calibrating with the Specrtaview II software and a DTP-94.  I understand that the SV kit NEC ships has an updated i1 colorimeter tuned for the wider gamut display.  How will a calibration with this new puck be different than with the old puck, or with a DTP-94?  Is it worth it to switch, or only if I didn't have one in the first place?

The DTP94 is an excellent device but it stems from the CRT days. Since it was optimized for such displays, it doesn't work well on wide gamut displays UNLESS the software that drives the instrument uses a calibration/correction matrix (EIZO, Quato).

So what is a good colormeter then? for wide gamut?

Apart from the $40-100.000 unit?

This is the bit I'm looking to know more about.  I use the "Factory Measurements" setting in Spectraview because I'm using a DTP-94.  If I bought the specially modified i1 for the wide gamut NECs, then I would be using the "Calibration Sensor Measurements", but how much better is it, if at all?  Will the change in profile be subtle, or will I feel like I've jumped another whole level in monitor quality?

And one more question, is the new optimized colorimeter appropriate for calibrating non-wide gamut displays using software like BasICColor Display, i1, Eizo's Color Navigator, etc..., or do we have to keep the old colorimeter around as well?

Colorimeters use filters based on the basic display chromaticity expected. The best solutions are custom mated (Barco, Sony Artisan etc). Others are based on general assumptions such as sRGB like units. The wide gamut displays are different and as such, having newer filter matrixes can produce more accurate readings for setting white point. Older units work as you've seen but your final calibration of white might be off a bit (in my case with the OPTIX, compared to measurements with a Spectrophotometer which has no such issues, about 500K). I wouldn't rush out and spend the money on a newer unit if you're getting good print to display matching however, if I didn't have a colorimeter, I'd get the newer unit more closely mated to the primaries of the wide gamut display.

QUESTION: Can I use the new MDSVSENSOR2 color sensor included in the new SVII-PRO-KIT with other 3rd party calibration applications?

ANSWER: Yes, however the custom calibration for NEC wide color gamut displays will not be available. Only the standard calibration is available.

The Spyder3 colorimeter has filters designed to handle the larger gamut of new LCD displays. I get a better profile from it than I do from an Eye One Pro Spectrophotometer.

Thanks for all the replies.  I also have an i1 spectro it sounds like I should try out to compare to the DTP-94.

I did try getting my monitor to match my D50 viewing booth and found that none of my instruments made a perfect match through measurements.  I ended up manually adjusting the white point with the RGB sliders in Spectraview and then the match was very close.

I wouldn't use the I1, it 's not suited for monitor calibration.
The I1 has difficulties measuring details in the dark shades...
