Re: NEC 2690 SpectraView



LOL,
Id like to think so because  "Im a customer" .
Im assuming you meant  "Definitely "  : )

We could start by you looking at the necdisplay site and trying to purchase. Its out of stock, all versions.
ive called their resellers referenced on their site:


Monitor outlet, CDW, Best Buy, MicroCenter, etc etc etc.......not only does anybody not know anything about the software, nobody carries it.

I was (and still am) preferring to purchase and use their own software (with the NEC monitors I own) and therefore give the product (the NEC 2690) more of the benefit than of doubt, than simply providing the performance as I have found doing hardware calibration/ profiling on these displays with my own software. What ive seen im not thrilled about.

I recall you mentioning NECs suggestion of a minimum luminance of 150cd/m2. I am finding (on more than one unit) that the value should not go much below 200cd/m2. If you do, the white point becomes less stable, enough so that you can see the color of white changing. I have found this with DTP94s, EyeOne D2s, Eye One Pros and even the Spyder3s.
I have found the black to also be rather poor, ie.....values in the . 6 to .8 cd/m2 and often much higher if you run over 200 cd/m2.
This is what lead me (ok, i assumed, shame on me) to believe it was a PVA panel, ie..lower my expectations. Being a high bit LUT display i would expect that value to be half of what ive measured.


As for white point calibrations D50 versus D65 this model doesnt appear to like D50. The color correction to achieve D50 seems too aggressive (watching the LUTs behavior) to maintain the the luminance in the minimum range to remain stable(noted above(for white)). Keep in mind the peak luminance on these are in the 350cd/m2 range. So asking for D50 at 200 cd/m2 is almost a bit too much to ask for, ie.......softproofing in a press room. If you want to run your calibrations at D65 its relatively "ok" as the corrections are closer to that of native white of the display (approx 6350k).
I have found the trade off is you have to run a higher luminance to get that stable white point but then you lose the black level accuracy. To obtain the more stable black value you need to run closer to the 150 luminance target but then you compromise the white point stability.


The ColorComp tool (ive seen this also on more than one unit) appears to be a screen uniformity enhancement tool. I find that turning that on gives me a green/pink compromise (upper to lower). So much so that it was better by turning that function off.

Now , this could be different with SpectraviewII software and if it is im more than happy to report that, but I have to be able to [buy] it before I can test it. I can only assume there would be some level of proprietary calls that may well improve this displays performance.

thanks

Oh you're defiantly on NEC's radar.
