If I have my facts straight, it looks like both the Dell m1330 and Sony SR have LED backlights... I'm not sure how that's different than the LED backlights that Andrew recommends, but I'm wondering how those displays perform?

Welcome to OPF Keeson!

If you are just starting to edit your pictures — or even very experienced in that — you will be perfectly happy with either of these monitors for that purpose. The larger gamut of the 2690 is an advantage for certain extremely critical color management purposes, but that's far from saying it's necessary. Most of us are editing our work on sRGB monitors, and many of us are doing it successfully on monitors that aren't nearly as good as the 2490, much less the 2690. And either of them very likely provides the most bang for your buck currently available for photo editing use.

What I can't tell you is which of these two would be better for non-photo applications like movies and games. You should check the gaming sites for reviews in that context.

ah damn! u found out that i m new to the forum! lol
anywayz thanks for the welcome =D

umm so does it really matter if it is sRGB or aRGB? for one reason that i would be liking the 2490 cuz it sRGB which most ppl are using for editing... and for the 2690 is that itz bigger and itz aRGB so i suppose when i do some gaming it would be nicer ( not saying itz gonna be bad for editing and most ppl tend to use sRGB over aRGB when editing ) so i m just a little lost lol

but thank you for ur info!

Cheers!

Adobe RGB will not be better for gaming. It's only better for some — some, mind you, not necessarily all — photo editing and other extremely color critical applications.

For gaming and movies you'll want (I think... this is way outside my bailiwick) to pay more attention to response times, ghosting, etc.

Nill, could you elaborate re the photo editing as it applies to converting raw color images to black and white. In selecting a monitor, does the % of Adobe coverage matter in achieving the best B/W conversion. This question excludes the issue of whether or not the output device can utilize the image viewed on the monitor.

Hi Rod, welcome to OPF.

The % Adobe RGB coverage (in principle) only affects the color accuracy. For black and white the most important thing is to get one's Gamma adjustment absolutely correct for each color channel. I like the gamma 2.2 chart from this site, to quickly judge the gamma calibration accuracy.

Correct per channel gamma will avoid false color casts in RGB black and white images, but it's probably even more important to get the output profile for a printer 100% correct, unless you only target on screen display. Viewing conditions will mainly determine your needs/possibilities for a good blackpoint, lighter tones are usually less of an issue for black and white alone.

Thanks for the reponses thus far. My concern is that using a monitor with less Adobe coverage would limit the range of tonal variations seen on screen vs a monitor with greater coverage. While it may only result in a subtle difference it could be a factor in the final output (given that the output device can reproduce the coverage)

Hi Andrew
do you think that the Eye One Display 2 would calibrate correctly the NEC SpectraView 3090 together with the SpectraView Profiler 4.1.9?
They both do calibrate the hardware of my NEC 2180UX

Thanks for your reply :)

The Colorimeter for sure. I would suspect the software too although it sounds like you're using the European version of the software? I'm not (I'm using the US) which does work fine but have no experience with that option.

There's the viewing issue if you will and the conversions which are separate.

Yes, a wide gamut display will visually produce higher delta's between smaller differences of color (or tone) than a smaller gamut display as I think I described. The output device is totally separate.

I don't know from which continent it comes from, I got it on NEC website:
http://www.spectraview.nec-display-solutions.com/license/?oemId=3&language=en
(need to log to have access to download area…)
it says:
SpectraView Profiler v4.1.9
... new calibration algorithm (CIECAM02),
....automatic hardware adjustment of JUST viewing booth via software,
....Universal Application (Mac with Intel processors support)
....Colorvision Spyder 3

SW windows and settings look really identical than Basicolor that I bought a few months ago…

So what about other calibrators?

I've read through this entire thread and probably settled on the 2490 even though most of what I do is photo editing. However, I already own the Spyder2 Pro calibration tool and software. While the SV II that comes with the 2490 might overall offer more capability for this monitor, will the Spyder2 calibrate this monitor?

Yes it will, and the "ColorVision/Datacolor Spyder 2" is also listed as a supported sensor for the Spectraview II software, meaning you could decide to buy that software separately (which I highly recommend) and use it with your existing sensor.

Very good and thanks for the quick response. In other words, I can get the Spectraview II software separately, use my Spyder 2 with it and save a couple of hundred bucks!

By the way, is the Spectraview II software availabe at the NEC site?

It will though the Eye-One Display 2 may be more accurate. In case you change your mind, though, NEC warn that the Spyder2 does not have a large enough gamut to accurately profile the 2690.

I just received the 2690 today, set it up and calibrated to 140cd/m2, native color temp with the i1d2 using the i1Match software. Even with Color Comp on I'm noticing a significant lightening of the corners when displaying a black image in a darkened room, pretty comparable to the Viewsonic VP930b I replaced with the 2690.

Is this normal/average/run-of-the-mill for this display? Or should I return it and ask for another?

Or should I wait for the SVII software and calibrate again? Will calibrating with the SVII help? Or any other suggestions?


TIA for your advice,
Bill

Hi Bill

Maybe you need to back off on the ColorComp somewhat. I find the screen display very even on mine, which is suggested by the PRAD review: http://www.prad.de/en/monitore/review/2007/review-nec-lcd2690wuxi-part9.html

I don't think calibrating will make any difference for that.

Murray,

Thanks for the suggestion. I played around with colorcomp for quite a while today and it didn't seem to make any significant difference in what I'm seeing. Tanks for the link to the review, I'm seeing much more variation in brightness than they reported. I'm even seeing it with normal task lighting using a black image for the desktop.

I started a new thread here: http://www.openphotographyforums.com/forums/showthread.php?p=57544#post57544 with some info on the settings I've come up with and since this is more of a technical problem and not really relevant to this discussion.

Thanx,
Bill

... If you're working on a subtle color image, its harder to see the differences in values on a wider gamut display. ..

I think it just the other way around. In sRGB, the deltaE2000 between the colors you give as an example is .434, while in aRGB, it is .515. This means you have a better chance to see the difference between two colors on a wider gamut display.

Of course, if your ultimate output is into sRGB, the wide gamut display might be deceiving....

Hi George, in case Andrew isn't around, I think the point that he was making is that a large gamut display may tend to swamp vry subtle changes in colour because the smallest differences it can display are bigger than the changes you are trying to make. Hence you cannot see the small changes.
