Title: NEC Calibration Problem
Post by: MNP500 on February 16, 2008, 07:00:47 pm
I just got a new NEC LCD2690Wuxi monitor with the SpectraView II software and the Eye-One Display 2 puck.  I calibrated, as some have suggested, to D65, 2.2, 150cd.

The display is too blue, and does not match my prints.  I had been using an old CRT with a Spyder2 with my Epson 3800, and various papers...that setup matched quite well.

Any suggestions?  Thanks

Michael

My settings for calibration with SpectraViewII (version 1.0.32 Build 61201) and the Eye One Display 2 are:
White Point: 6500K
Gamma: 2.20
Intensity: 120 cd/m²

I print with a Z3100 through Qimage. Beside the self calibration of the printer with this software it's very easy to check the profiles of your monitor and the printer in the settings of the Job Properties. Do you have disabled all other calibration software on your computer?

[a href=\"index.php?act=findpost&pid=175452\"][{POST_SNAPBACK}][/a]

I have recalibrated to 120cd.

I'm viewing under tungsten in my office, but also looking at prints under daylight.  Yes, in daylight the colors are much closer.  Under tungsten, they're awful.  But in both tungsten and daylight the NEC image is brighter and more saturated than the prints.  So if I get saturation to my liking on screen, the prints are flat.  Hmmm....?

Thanks all for the help

You've got to either make two calibration presets and switch based on the viewing or stick with "Daylight" (better). Nearly all ICC output profiles assume a D50 ("Daylight") viewing so I'd say, the tungsten viewing is not effective. The luminance needs to be matched to viewing too. So if the display looks too light, you need to lower that target. But a new LCD is going to have a tough time getting much lower than 120 cd/m2. So up the intensity of the daylight (IOW, you need to CONTROL this, you can't just look at the display, then pop a print nearby a window and expect a match).

You might want to look at some Solux viewing lights and set them distance wise for a correct intensity:

You should also be setting up Photoshop's proof setup correctly:

Can I admit to being a little more confused than this? I have two questions:

1. I bought my 2690Wuxi without the NEC calibrator, having been advised by a number of people that my Spyder2 would do just as well.
But the NEC user guide, while listing the extraordinary number of controls available to the user, makes no mention of which of them should be used to achieve color fidelity. I'm assuming most of the controls are for people not using hardware calibration, but that's really my question: am I supposed to be doing anything other than using the Spyder and its software (as I was doing with my previous Apple 23" monitor)? If so, is there someplace I can find such this information?

2. the Colorvision Spyder software says to run it with the monitor set at factory brightness, but this will melt my eyes or give me a sunburn, whichever comes first. Is there any problem in turning this thing down to something like 85 or 90% and calibrating from there?
Thanks.

Just to be clear - you are using the Spyder software and not the nec spectraview II software?

If you are using the Spyder 2 and spyder software you are not accessing the monitors internal 12-but LUT. You are doing the calibration soley to your video card via the Spyder software.

SpectraView II software is required to get the best out of this monitor - see:
[a href=\"http://www.necdisplay.com/SupportCenter/Monitors/spectraview2/]Spectra View II[/url]

I suspect the problem is with the calibration LUT in the video card - not the monitor.

There's a little confusion here. I'm the original poster.. J Mandell is the guy currently using the Spyder.  I'm using SpectraView, and now that I've calibrated to 120cd and am viewing prints with a daylight bulb, the colors are, in many cases, very good.

I'm still having color shifts with certain kind of prints (prints slightly on the green side), so I'm not sure what to do about that.  Soft-proofing does not show the green cast, so something else is wrong...or perhaps I can't expect WYSIWYG for everything...?

Is this with just this one profile or all profiles? If just one, then its one of the tables.
It could be either the output profile table or the preview portion of the table not being in sync. You need to now output documents of known color properties (like my Printer Test File). If they appear OK, then the soft proof table is suspect. If they print green, its the output table.

Thanks Andrew.  I'm getting similar results with 3 papers/profiles: Epson Luster, Epson Exhibition Fibre, and Ilford Gold Silk Fibre.  The image in question is fairly high contrast shot--white swan on quite black water--the black water particularly has a greenish tint.. on screen it's very neutral.  Other images, with a more usual color dispersement, don't seem to have the problem as much, if at all.  I need to do more testing, and have also ordered a Solux light.

Where can I get your Printer Test File?

BTW, I enjoy your version of the RCA Nipper.  Being an old vinyl listener (I still listen and have quite a collection of RCA "Shaded Dogs") I got a kick out of it.

For what it's worth, I just got the same monitor and calibrator combination as you, and I also print to a 3800 (in my case, usually to Ilford Galerie Smooth Gloss paper, with Ilford's canned profile for the 3800).  I did my first calibration yesterday, compared the monitor with some test prints, and was pleasantly surprised that prints and monitor matched extremely closely.  I was viewing the prints under a frosted skylight with blue-sky direct sun through it, and my target settings in SVII were 6500K (very similar to D65, I believe), gamma 2.2, and intensity 100.  I started with those settings because those were the ones I used to use with my old CRT monitor, but they worked so well with the NEC that I'm continuing to use them.

In doing the monitor/print comparisons, I compared bright colors, overall brightness, shadow detail and neutrality of a B&W image, and the settings above worked very well for me.

I wonder whether one's choice of print paper (and the quality of the associated profile) makes a significant difference in the quality of the print/monitor match???

I also just purchased the 2690Wuxi with the Spectraview software. First I am amazed how poor my EyeOne Display software is at calibration! No matter what the settings, my monitors looked magenta. Using Spectraview on my 2690Wuxi my colors are dead on. Unfortunately I had been used to viewing  images too magenta.

I have a problem with very wide soft diffused bars moving vertically on my monitor when I have a plain screen (solid desktop or solid background file in Photoshop). My settings are D65, gamma 2.2, and 110cd. It almost appears like horizontal smoke signals. My refresh rate is locked at 60hz.

Has anyone else noticed this?

Nec believes it to be a defective monitor and will swap monitors for me. Nec is by far the best customer support I have ever dealt with, Apple should take a lesson or two from them because they are the worst.



Thanks,

Jim

I'll second that!  I couldn't find the 2690 bundled with the calibrator/software for sale anywhere reputable, and started an email conversation with someone at NEC customer support to see if they had any idea where I could buy it.  I eventually ended up buying the monitor from amazon and the calibrator/software directly from NEC.  The NEC rep confirmed that buying them separately would give me exactly the same system as buying them together, and answered various other questions, and generally was extremely helpful and gracious about it.  I was emailing back & forth with the same person through the entire exchange, which always helps.

Well, NEC Europe could learn a thing or two from their colleagues in the US.

I was in the market for a 2690 SpectraView, but my emails to NEC here in the Netherlands and their headquarters in Germany were never answered, telephones weren't picked up, the unavailability of SpectraView II software in Europe, a well known supplier in the UK (Colour Confidence) complaining about the lack of support...

I just got fed up with them and bought the EIZO CG241W. Now I'm happy too.

Andrew,  I printed out your test sheet and am still getting a greenish cast.  I even tried it with some matte paper using a custom profile I had made for it.

These attachments show more or less what I'm getting although the scan is a bit darker than my prints, but the cast is the same.  These are obviously crops--one made from your jpeg and the other a scan of my print with Luster paper.

According to your prior post, this would indicate a problem with the output profile.  What is that and how do I deal with that?  Thanks

The scan you see is a standard profile from Epson for Premium Luster paper.  But I tried it with a Moab paper I use where a professional profile was made for me by someone at Moab.  The results are just about the same.  I'll check the inks etc. but I doubt that's the problem. This is driving me crazy.  Thanks for your help

OK, I waited a bit so the original poster could have this thread to himself. Didn't mean to confuse things.
No, I'm just using the Spyder software, but in my defense, the monitor didn't come with any software, nor does the owner's guide tell me to download and use any. That's why I knew something seemed wrong and why I'm posting this.
So am I to search the NEC site, find the spectraview software, hope it's free and if not call them and ask for it, then run it using the spyder hardware?
And after that, I still have my original question, which is what about all the other controls available on the monitor itself?
Thanks for the help.

Its not free, its $99 but man, money well spent. You can use the Spyder although NEC doesn't recommend it.

They are irrelivent if you use the Spectraview II software -which you need to use to access the monitors 12 but LUT.

In fact, there is an option in the software to lock out the actual monitor hard controls to avoid messing up the calibration.

<<They are irrelivent if you use the Spectraview II software -which you need to use to access the monitors 12 but LUT.>>

So they are only there for those who spend the money to buy this exceptional monitor, but don't use hardware calibration? And then there are really no instructions for how to use them?
I get it, but it seems kinda weird.
Thanks for this info. I'm going to take advantage of the NEC price break and buy both the software and the puck, but I note that notwithstanding the negative comments here, I've had surprisingly good success with the Spyder 2 and my Apple 23" once I finally started soft proofing correctly. I am looking forward to doing even better with this new package.

Note to NEC: Something about Spectraview should be in the user's manual or at least in the box (in addition to the note about the availability of Naviset).
In other words, the customer has to really work at this to figure out what he/she needs.

A couple of thoughts.  Are there any RF devices near your monitor (cordless phone, wireless keyboard/mouse and transmitter, accoustsc speakers, etc)?  You might try moving them to see if there is any interference.

Also, have you updated your video/graphics card drivers recently? Not sure if this will help, but couldn't hurt.

<<Its not free, its $99 but man, money well spent. You can use the Spyder although NEC doesn't recommend it. >>

Actually, the info that came with the software says that NEC officially recommends not using the Spyder! They say it can't handle the full spectrum of this monitor. Good thing I popped for the Spectraview Kit, including their colorimeter  (and nice that it was only another $100 while on sale this month).
Anyway, I just got it, glanced at the instructions and sighed, realizing it would take a bit of doing to read and understand it. I have two questions:
1. Is it OK to reduce the brightness prior to calibrating? This thing at 100% is unbearably bright for me.
2. Since I'm using your profiles for Epson Exhibition paper, would you mind telling me what settings I should be using to calibrate in SpectraView? I assume D65, Gamma 2.2? Yes? And if so, what else please? I'm a photographer, and I will be using my display for soft proofing Epson inkjet prints.

Thanks to all for your help.

Don't worry about setting the brightness, the software will do that when you tell it what luminance you want.

Yes, I'd start D65 TRC2.2. Maybe 150cd/m2 (again, that's based on viewing conditions).

Thanks! I shall do as soon as I've got some time!

Did anybody do any comparison between the two?

Is it possible to compare different profiles at all (wondering because it gets partly written into the AGP card and affects brightness and contrast settings as well)?

Yes, I'd start D65 TRC2.2. Maybe 150cd/m2

Hmmm... I have another question: the only canned setting that gives the user D65 and a 2.2 gamma is Broadcast Video. Do I use that or do I use something else and change the parameters? I've done the Broadcast Video, but the curve it produces isn't flat by a wide margin. On the other hand, I have to say, I'm not sure what kind of curve I'm looking at.
Thanks.

(By the way, the 150 setting works fine, but out of curiosity, what does m2 mean?)

m2=square meteres...

According to NEC gamma 2.2 doesn't make sens with LCD monitors. They recommend the L* setting.

Maybe someone in Europe with that version, but not with the US software, pick gamma 2.2.

J. you can modify a setting and save off a custom target to use so yes, start with Broadcast Video and modify to your needs or just make a new custom target and set as you wish and save.

Cd/m2 is the unit of measured luminance (Candela's per meter squared).

Hi MNP500:

I've arrived at this party pretty late, and don't know if you've got your issues sorted out.

If not, you may want to run the Eye-One Diagnostic on your puck. GMB replaced mine under warranty a few months ago when my profiles got wonky, and the puck failed the diagnostic tests.  

You should have the software on the dvd that came with the puck, or I think you can download it from Gretag Macbeth's website.

Hope this helps.
