Roma,

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.
What about your graphics card driver, check that for updates too. There seems to be something strange going on and I wonder if it is with the graphics card.
Alternatively there is a fault with the monitor; it should not be as difficult this.
Some observations/comments:
Contrast 100%, why so high? Ignore the software recommendation to set to 100% and leave at factory setting, around 50% I assume, like in the article. You will find that the software will accept that and no contrast adjustments are required.
The minimum luminance values on the results are high; I would expect values of less than 0.5, probably around 0.2 CD/M2. The poor result is possibly related to the high contrast setting.
You must use the custom mode for calibration, the other pre-sets are what they say and will override the monitor settings.
Is there anything else that could affect the brightness setting like an automatic adjustment for ambient light? If there is it must be turned off for calibration.
That's as much as I can think of at present.
Terry.

Roma--  I agree with Terry...  Set your Brightness to 30%, your Contrast to 50%, than LEAVE THEM ALONE!!!  Forgive me for yelling but I do website tech support for my company and I often have to tell our employees, "Listen to my words and instructions only and not the demonic voices in your head telling you to do something else!"

Only adjust the RGBs as needed to to get "CLOSE TO" 6500k.  Don't try for perfection as the software will take up the slack.  The point of adjusting the RGBs is so that less color correction work is put upon your video card.  The reason I recommend MINIMAL RGB adjustment from the default settings, is that the more you deviate from the factory settings, the more color tones you are throwing away, and the more likelihood of causing "banding" or "posterization" on your display.

Hello,

Thank you, Terry and Chas, for your comments. One thing I have changed - I REMOVED the ambient light attachment. I know it sounds silly, but I listened to a salesman who left it on when he arranged the product demonstation. I have read a lot today and even in the one-page instruction, which came with the unit, they said to remove it!

OK. I redone my calibrations (sorry, Chas, I read your message after I finished). Before I began, I noticed GENERAL OPTIONS screen (image is attached). This option has never been explained anywhere. Which options do I have to use? I have tried both - for small display (image is attached) and for Large display. This was done in Native White colour mode.
In all calibrations, when I followed the instructions and set up Contrast to 100, after calibration it went down to 63-64. However, my brightness from 0 did not move anywhere as after the constract calibration it stayed too high at 136-142. Certainly, the final result - luminance was too high - about 140. This is in the Standard mode with final contract at 63% and Brightness at 0%.

I also calibrated at 6500K. Before the calibration I switched to Colour Mode and made sure that the colours were set at the default setting 50-50-50. This time contrast from 100% did not move anywhere and  stayed right in the middle. Colour calibration was fairly good, the final RGB setting is 64-54-58. They were not perfect but very close to it. Calibration of Brightness was good and it produced 120 easily at 56%.
The final report was fairly good (attached).

When I am using this setting right now, I see that the screen is a bit pink. Certainly 100 Contrast is strange, but Colour Mode is not bright to start with. Perhaps low default setting (50-50-50) is responsible for it. Visualy I would not be happy with the calibration as the colour of the screen is pink instead of white and the brightness affects my eyes.

I will try a calibration at 30-50 Brightness/Constrast. However, if this parameters should not be calibrated, how do we know that they are right? Why not 40-60? From the review referred by Terry one can see that the calibration was successful producing 30-50, but not in my case.

Any comments would be greatly appreciated.

EDIT:Where are these options? I don't recognise them from the IMatch 3 software used with EyeOne display 2. I'm confused, are you in fact using a ColorMunki? REply #4 on this thread says you have an Eye1 - 2. Ok I found that on IMatch3, I am  using the "Large LUT" setting.
Use the large display (LUT) option. This indicates that the LUT (look up table) in the graphics card is loaded by the profile which is what you want.

IMatch 3 software seems to accept any value of contrast you set as correct; I think this is the case for LCD but not for CRT monitors
I really think you should use 50% contrast, your minimum luminance value is still on the high side and that may be why.
I note too that your gamma is a little off, 2.3 instead of 2.2. I'm not sure what you can do to improve that, I used to get the same thing on my previous (budget) monitor.

I expect this is purely your perception, you really do have to rely on the calibration and not your eyes.

What do you mean here? 120CD/M2 is the normal value for luminance on a LCD monitor!

Yes, please do. Leave contrast alone at 50% but you may have to adjust the brightness a little after setting the RGB values which should be in the order of 80 to 90%.
A note for Chas, the IMatch 3 software gets you to set the brightness (and therefore luminance) after setting the RGB values so a little tweak at that stage is likely to be required.

You seem to be getting there  Wink

Yeah... I actually owned and used an iOne Display 2 for a while before I sold it to buy my DTP-94 puck.  All these mainstream monitor calibration packages are very much alike, differing mainly in their GUIs.

Hello again,

Well, after a lot of reading and thinking, also trying different calibration modes, I decided to send back the Dell U2410. First reason - not too happy with calibration results. Main reason - I wanted to use the monitor for photography also for reading text. Reading text is not as good as on my old ViewSonic VG2230wm, which is just  a TN panel. However, less painful for eyes...

By the way, when I tried to calibrate the ViewSonic yesterday, my results were not bad. I will post them later, though they are not very important as the screen was not designed for  colour accuracy.

Now I am thinking about Dell 2209WA as somebody has suggested on the forum. I will certainly wait when it will be on sale as the regular price is unrealistic for the monitor with limited functions and connections. It could be a good panel for reading text and working with pictures. Any thoughts?

I would certainly love to buy NEC 2490, however, in Canada its price is way too high ($949) when in the USA it is only ~$700. Canadian dollar is par to USD now or very close.
Thank you,
Roma

A little afterthought inspired by a discussion I read on another forum.  Regarding Contrast settings... when these calibration devices instruct you to set monitor Contrast to 100%, that should should NOT be taken literally.  The INTENT is 100% of the factory default value, which may be 100%, 75%, 50%, or whatever.  On my personal monitor, that setting is 75%, so I keep Contrast at full factory setting-- 75%.  Even 1% higher than this starts to clip highlight tones.

Hello Chas,

That is a very interesting thought. I will certainly check it out when I have a better monitor. Do you still own Dell2209WA and what you think about it now? I am going to try it out when on sale.

As I can see from your latest post, the recommended setting while calibrating are not to follow all the time. Perhaps, somebody else will share his/her experience. That would be great for someone like me who makes first steps and learns from others.

I still own, use, and love the 2209WA for what it is:  A great value in an ENTRY LEVEL photo editing monitor.  If you're making your living from photography, or plan to, I would think you'd want to invest in more professional equipment.  On another forum I contribute to, I'm always amused by members who list their other equipment-- tens of thousands of dollars/euros in lenses and camera bodies, but edit photos with the cheapest quality monitors.

Well, finally I purchased CM and what a spectrophotometer it is GREAT!
My U2410 profiles perfectly in Standard mode at 30 brightness and 50 contrast.
My paper profiles rival those made professionally at $30 a clip before.
Worth every penny.
BTW, I also discovered a new software from Quato in Germany, iColor Display. It has a "correction matrix" for dtp94 to use with wide gamut monitors. It's the best software I have used so far. They tell me that later in 2010 it will support CM as well.

Adam,

I have a U2410 at work that I will be using for editing videos.  I currently have it set to the Adobe RGB setting in the menu.  It's supposedly been factory-calibrated, but I'm wondering whether your calibration with CM results in a noticable difference.  I have a CM at home (I love it too) and wonder if it will make a difference in the accuracy of the U2410.

Thanks

IMHO it will make a noticeable difference, but try calibrating it in standard mode setting br to 30 and contr to 50, RGB will not be accessible on OSD.
Try it. What you got to loose?

Hello Adam,

Perhaps I was not lucky with the U2410 as my calibratration was not good as I explained in my previous posts. I can see you sucessfully calibrated it in the Standard mode and reached 30 and 50 for brightness and contrast.
For your calibration you used CM, however, I could not find information on the net. Could you please provide more information so I could read about it? I am still thinking if EyeOne 2 is good for me, as I have read about dpt-94 which is a good product as many reported. However, it is sold with various software, what is confusing.

Please let me know what you think.
Best,

Roma

Roma, perhaps it's just a language thing, but Adam did not "reach" 30 and 50 for Brightness and Contrast.  He PRESET the monitor to these settings BEFORE running the software and he did not touch the Brightness  and Contrast controls again.  I agree with Adam when he says

Hello Chas,

I can see it now. Thank you for clarifying this point. I believe when a monitor gets old, these settings must be changed. There is so much to try out, as the standard software and recommendations do not always work. What is CM? Just wonder.

I am now waiting for DELL to put 2209WA monitor on sale. In the meantime I have noticed that NEC is selling refurbished LCD2690WUXi-2 for a very attractive price ($749 USD). I have read reviews and they are very good.
http://www.necdisplay.com/Products/Product/?product=02e0c734-0bbf-4b25-bb28-03d1e7f855cd

I do not do professional photography, but I would like to have a monitor I can trust in terms of colour reproduction. Should be good for wrokign with text too though.
Thank you!
