I'm thinking buying it, but before I do, I would like some input from actual users. It would replace my dtp94 colorimeter.
Thank you!

Do a search on "colormunki" and just "munki" on this forum and you'll see some comments about it already.

Hello Terri,

Do you think Eye One 2 is a good calorimeter? I have purchased it, but first time I used it on U2410 I could not get any normal results. I trust that the colorimeter works fine.

Please advise.

What's a normal result?

Hello,
I used the Eye One 2 first time in my life and my first results were far away from what I read on the forum. For the U2410 in Advanced mode, after I adjusted contract to 69, brightness reached only 59. When I tried again, though the contract changed slightly, the brightness was still less than half of 120 (59) even though I top it up to 100%. For these two tests I used 6500 settings. When I tried Native White Point, the number was higher and almost reached 120, but then was sliding down and stabilized at around 103. After I proceeded to the end of the calibration the final report showed 130! I am reading the forum to find answers. Perhaps I am doing something wrong as I have no experience with any calorimeters. For example, after I read the tutorial, I am not sure if I have to do the Eye One 2 calibration (on a black non-reflective surface). So far, I certainly see that I need more knowledge about how to calibrate properly using this calorimeter.
Best wishes,
Roma

Hello,

I have just completed two more calibrations with my brand new Eye One 2. Both calibrations are not good as the 120 target was not even within reach. In 6500 degrees calibration, I had to use 100% brightness without much luck.  Colours are much worse than in the Dell settings. Is it a monitor or a calibrator problem? Any comments would be greatly appreciated.

Thank you,
Roma

It seems to me that that monitor electronics vary considerably and, particularly cheaper models, have limited scope for adjustments.
Look at my comments here and on this thread generally:
http://ddisoftware.com/tech/computer-hardware/improve-your-monitor-calibration-result/msg5269/#msg5269

If you go back to the Dell settings and calibrate in "Simple" mode , the graphics card LUT will look after most things except brightness.
If you use the IMatch 3 software in Advanced mode, when you adjust for Colour Temperature, you need to increase the individual RGB values (gain) so that the target luminance can be achieved. The RGB Gain and Brightness settings are linked.

It's really how you set the monitor, the calibrator just reads what it sees on the screen.
Hope that helps.

Hello Terry,

Good to hear from you as you are use Eye One 2 with great results posted on the forum. Thank you for the link. I have read this forum a few times by now looking for answers. Very interesting and educational. I will try to put colour settings higher as the monitor does not have colour temperature settings and all colours are set at 50%. Perhaps that explains why black letters do not look black as on my Philips monitor at work.

I am happy to hear your opinion that the Eye One 2 is working. What do you think about LaCie Blue Eye?
Thank you,

Roma

Roma, if the factory default settings for RGB is 50%, you don't want to raise them any higher.  Lowering them slightly to white balance the monitor is acceptable and should not cause any noticeable banding.

Hello ChasP505,

But in this case I will never be able to reach 120!

Roma

Raising the RGB gains will only raise your luminance further!  You should only adjust the RGBs (minimally) to white balance and hit a "color temperature" such as 6500k.  Use your Brightness and Contrast controls to achieve a luminance value such as 120cd/m2.  And don't confuse the monitors Brightness setting with a luminance value.

120cd/m2 Luminance should be easy as cake to reach on the Dell U2410.   Read this review:
http://www.tftcentral.co.uk/reviews/dell_u2410.htm

They used a Brightness setting of 30% and Contrast 50%.

A useful article, and looks like it's an excellent monitor.
After scanning through this report, wonder if Roma is attempting calibration while in one of the pre-set modes (sRGB or AdobeRGB), rather than using the "custom color preset mode" and that's causing problems.
Just a thought and worth checking.

Their RGB values were 82%, 86%, 83%.
That should be a good guide for Roma to get a sensible luminance value and 6500K  Smiley
Probably coincidence, but the % values are similar to those I use on my Eizo  Shocked

Roma, you asked

I know nothing about it, sorry.

PS. I noted that the review of the Eye One Display 2 on that TFT Central web site is now out of date with respect to the software. The software does now have (since 18 months ago at least) a means of validation and giving the Delta E results.

Yeah... And their review of the ColorEyes Display Pro software that I use is flawed.  They omitted the key step of setting the white balance.  I think they are in bed with LaCie BlueEye as they use that software as their reference standard.  It's excellent software but no better then many other software packages available.

Hello,
Thank you for looking into my issue. I have checked all possible modes with the same success. First of all, I went to the X-Rite site and checked if my driver was up to date. No. I downloaded the update and installed a newer driver. Then I checked if the solfware was up to date. No. The latest version is v.3.6.2. I reinstalled it as well.

Then I calibrated the monitor in Standard mode using Native White Point settings with 2.2 and 120. Same result - after brightness was adjusted to 100 it gave me 94.3 reading. The final calibration report is as follows.
Then I calibrated the monitor again in Standard mode using 6500K. Brightness was adjusted to 100 giving only 40.5 reading. The final calibration report is attached.

Then I read Terry's post and decided to check his idea. I used Customs Colour mode and 6500K. Default settings for RGB were 50-50-50. My contract from 100 did not go down at all! Calibrating the colour was very hard as the bars were jumping from one side to another. Though the result was not perfect, at 51-43-49 it was somewhat close. I decided to check it I could get something interesting at the recommended 82-86-83 setting. I put those numbers, and the final (not perfect) result was at 81-70-80. Again, I do not know much about the perfect colour calibration, but I could not get the bars perfectly at ZERO mark. Because the colours numbers were this time higher than before, as expected after adjusting brightness to 100% the reading was 88.5. Still not at 120. Final calibration report is as follows.

When I sat down to write this post, the screen was so bright (100% contrast and 100% brightness) that it was impossible. I had to bring everything back to Standard mode and 30 Brightness - 43 contrast.

I know it sound all very unusual to you, however, I have never seen anybody calibrating a monitor other than an Apple Display, what is different. Please help me to find out what is wrong. It makes me believe that my sensor could be less sensitive fro some reasons, however, when I used a test from the X-Rite site, it passed it without problem. What else could be wrong? What do you do before the calibration?

I tried to use the same devise at work on my display. The same result - Luminance was not even close to 120. I am going to the shop tomorrow to check if they could check my unit or give me another one to test. As they calibrate the Apple Display, I do not expect to help me much. Very frustrating experience, not good yet, but I am willing to get to the bottom of it and learn from you.

Hello Again,

I have read many reviews on this monitor before I bought it. It is considered to be a great monitor by most users and all reviewers. However, I still can not get it to work (agree) with my EyeOne 2!. I have bought it to read text and work with pictures. I am now more inclined to replace it with Dell 2209WA as it has been recommended on this forum. It does not have many features of U2410, but could be good for text reading and working with pictures.
However, now I must find out how EyeOne 2 works. So far after a lot of reading and watching video I have not seen anything I have not done yet to make it to work.
