Hi Adam,

It is a graphical representation of you video card lut. For example, to get an output of 128 for green channel, it requires an input of aprox 140. If you really want to puzzle over it, download the icc profile inspector, linked from here, say,  http://www.iccview.de/content/blogcategory/10/18/lang,en/.

It also shows you can't get black, or white, but near enough not to worry, I expect  (to get to black you'd have to input values less than zero, and to achieve a white it would be a tad more than 256).

In the help file, it is explained how the curve can be adjusted at the extremities, to get a better profile, iirc. (black output offset)

The grey line indicates an uncalibrated/perfect situation, no lut being required, the input equals the output.

Plenty of settings to fiddle with, if you have a mind to.

hth.

Best wishes,

Ray

Hi Adam,

'Best' is the problem Smiley. If you read the help file, it explains in some detail how the profiles/curves can be altered, for specific purposes. I think if you run some tests with your own images, you may not notice much difference in using any of these profiles, except in the dark areas, maybe. If you spend a day or two on http://www.normankoren.com/makingfineprints1A.html - and following the various links, there are various test strips and charts you can try, and other explanations.

I've sent you a pm.

Best wishes,

Ray

Hello,

I am new to the forum and have just registered to share my concerns about the U2410 monitor. I got it about 10 days ago, I also purchased Eye One 2 to calibrate it. As I can see, Terry has the same calibrator and his results are excellent. My results were disaster. Basically on both Normal White mode and 6500 I never was able to reach luminence close to 120 even at 100 brightness. I will post more details later. However, I believe that this could be a monitor issue rather than the calibrator problem, which is a brand new.

I will read the whole forum again and look at the calibration results when I am home. Any advice would be greatly appreciated as my experience with monitors calibration is next to nothing.
Thank you in advance,

Roma

Terry should be back on here by late tomorrow. He is busy for a few days.

Roma--  Just for kicks, try these settings when you recalibrate:

Brightness:  30
Contrast: 50
Preset Mode:  Standard

Roma,
From what I gather from many forums colorimeter doesn't do a very good job calibrating "wide gamut" monitors. For that you need Colormunki, which is spectrophotometer, like i1 pro. Another alternative is to get correction matrix from Quata, which makes iDisplay Color, but it costs additional. I can't accurately calibrate with dpt94 (OPTIXXR) either. These are the only ways to get good calibration of such a monitors.
Read on the forums and you will see what I mean.

Hello Adam,
Thank you for your opinion. You probably are very right. As my experience is very limited (to one monitor) I can not say anything. I have my old ViewSonic and will try the Eye One 2 on it tomorrow. As I can see from the forum, Terry has successfully used this device. So far, results which I posted on another forum here are very bad with luminance reaching only 37.5 at 6500K set up.
I have read that some people have successfully used LaCie Blue Eye for the monitor. Is it better? Could you tell? I have been told that it is the same puck with different software.
Thank you,
Roma

that is, an EyeOne Display 2
That is correct and with a wide gamut monitor. I use the Advanced mode which allows setting everything but I leave the Contrast setting at "Native" (50% in my case)
I doubt that most people would not "see" any difference whether calibrated with a colorimeter or spectro' device. A comparison of validation results might reveal a difference. Does the ColorMunki have a validation feature in it's software?
