I am having trouble calibrating and profiling the DELL 3008WFP wide gamut LCD monitor. I've got an Eye-One Display 2 device, using the latest version of it's drivers and the i1 Match software (have also tried using the open source Argyll CMS software), with the same results: under color managed applications (such as Capture One or Photoshop) the color is off and the saturation is very weak. I have tried the calibration and profiling on several different computers connected to this monitor, with differing operating systems (both XP and Vista), with roughly the same results.

I am familiar with the information presented in the thread regarding the supposed incompatibility of this colorimeter with wide gamut monitors:
http://luminous-landscape.com/forum/index....showtopic=27934
However, X-Rite manufacturer support stated that the regular i1 Display 2 is tested and compatible (even bundled with) wide gamut monitors.

To make things more interesting, there actually is an ICC profile that works in a limited way: the LG W3000H monitor (which supposedly uses the same panel and backlight) has a downloadable profile that allows me to work in color managed applications. The white point is a bit off (I had to create a custom RGB setting in the OSD menu to adjust for the purplish colors the profile produces) but it's almost ok: it's colors are very close to my regular gamut monitor.

My question is the following: has anyone had success calibrating and profiling this monitor, if yes with what kind of hardware?
Do I really need an expensive spectrophotometer to calibrate the wide gamut LCD, or is there a colorimeter that is known to work?

I am most interested in hands-on experience with this monitor, but I welcome any other helpful insight.

Hi Greg,

Just got me one of these monitors about a month ago. I have had great success with Spyder3 Elite and basiCColor Display.

I have a HP LP2475W and I have the same problem. I don't know what to do!
I used Spyder 3 Elete and monitor is more saturated that my other one (Viewsonic VP2130)
When I enable my color management in Silky Pix colors turn greyish and muted

Anyone figure this out yet?  I have a 3008wfp and am having similar issues.  On the other hand, I've figured out a few things.  Read this page:

http://www.gballard.net/photoshop/srgb_wide_gamut.html#_1

and this page:

http://www.earthboundlight.com/phototips/f...management.html

And note that setting that one variable from 2 to 1 seems to resolve web-viewing issues.

Okay, but I'm not sure if what I'm looking at in PS is what other people would see given an A-RGB image.  I used the Spyder3, which is supposed to be the device to use for the wide gamut monitors.


I think my PS images may be more muted, but am not sure.  The above 2 links and commentary may be all of what is going on, or there may still be a lack of saturation in PS.  

Are you guys looking at PS images compared to internet images?  If so, then those pages describe your problem.  Is that it?  Or is there more to it?


One thing that is interesting - during the calibration portion of the Spyder3 process I ended up with R-100, G-78, B-89.  Moving G from 78 to 100 seems similar to what is happening to my images.  If you go to View/ProofSetup and choose monitorRGB that will show you the over-saturated version - which is also what you will see opening the images in Picture and Fax Viewer on the wide-gamut monitors.  If you go choose WindowsRGB (assuming you did a good calibration) or choose no proof setup that *should* be the real image.

But I'm not sure.

Could be the instrument but usually, when comparing wide gamut displays and issues with Colorimeters that expect an sRGB matrix vs. a Spectrophotometer, the issue is an error in the white point, not something that would affect saturation (which is what it appears the various users having problems are seeing). Could be the backlight, but again, when I’ve run into such issues, again its a cast that results.

I don't think any of the equipment is faulty, I think I don't know what the heck I'm doing!  Though I've learned a lot in the last 3 days.  

On the first link above, assuming you have a wide gamut monitor, do you see a difference in the first image when you do a mouse rollover?  I think any wide gamut monitor should.  Then, per the second link, if you change that one parameter from a 1 to a 2 you should then *not* see a difference in the first image during a rollover, as Firefox will then use profiles, and the wide-gamut problem of over-saturation when showing a non-profiled image will go away.

Also - do you have any ideas about the last paragraph in my above post?  Did you change your RGB values on the OSD?  Do you then get the same result I get under View/ProofSetup.

If you don't have one of these monitors, or extremely similar, you won't be able to test:

Dell UltraSharp 2407/8WFP 24"
DELL UltraSharp 3008WFP
EIZO ColorEdge CG241W
Eizo CG301W 30"
NEC MultiSync LCD2490WUXi-BK (24-inch)

What link with the roll-over? Perhaps this: http://www.color.org/version4html.xalter

I do have an NEC 3090 (and a PA241W). The four squares are identical.

On the first link on my post above there describing one of the main issues with wide-gamut monitors:

Yes, I see a difference on the 3090.

Yeah, you can fix that by changing the parameter from 2 to 1 (management mode I think) on the other link in the post above.

I got so annoyed at this process, I actually took my whole monitor and computer to a high-end store and compared it to an Eizo.  Actually, it went well.  The 3008wfp definitely had a bit more contrast (don't know if that is good or bad, but there it is).  They had a colormunki-calibrated end-to-end connection between the Eizo and a 3880 and we did a test print of the image we were looking at in each monitor, and it actually had a bit more contrast than the Eizo and matched my 3008wfp better!  So, that was good.  So I'm now feeling more comfortable that the monitor is calibrated right.  But it doesn't help that srgb can look wrong on any wide-gamut, non-color managed stuff looks horrible, etc.

The other thing I didn't know, but at this price point you have to accept something, is that when you lower the rgb values on your screen it does compress the color space for that color.  This is not the case on the NEC or Eizo.  Of course I got 30 inches for around 1450, and the 24 inch is 2400 from Eizo and around 5k for th 30 inch!  But they are actually really doing something, when you change RGB they go through the 12-bit LUT process which doesn't change the whole range for that color.  So my green is at 77, and now I will only be able to see 77% of all the greens (or so, its not necessarily linear).


I know some people calibrate without using the RGB controls - for the 3008 via Spyder3 do you think using the RGB OSD controls is best?  It isn't clear to me how much power the calibrating process has to change things in the graphics card vs using the OSD monitor controls.  I don't know what it can change, perhaps it can change enough that its better to stick with 100 on R, G, B?

What is your take on that?

I’d do everything via the SpectraView II software (which supports the newer Spyders).

My Dell 2408 had a similar problem when I got it.  In the review listed below, they recommended using the custom color presets instead of SRGB or aRGB presets.

Hi, sorry to dig out this thread, but I'm also having some difficulty with my 3008WFP. Compared to my 2001FP, the colours just don't look right in colour aware programs like NX2 and ACR. The embedded JPEGs look ok, but the renedered RAWs look wrong on the 3008WFP, but are ok on the 2001FP.

In my frustration, I've stumbled across an oddity; setting the 3008WFP's profile to sRGB renders the colours correctly, but the white point is a bit off, as expected. Does anyone know what is going on here? My usual way has worked till the 3008WFP.

Yes, the 2001FP only covers the sRGB gamut and the 3008 WFP goes significantly beyond that. Images on the 3008 are probably going to look more saturated compared to the 2001.
