If using Firefox, remember to load it in Firefox- Add-ons- Color Management- Preference- All Images. Once loaded, open Photoshop and direct it to use that ICM.
* Open Color Management by clicking the Start button, and then clicking Control Panel
* In the search box, type color management, and then click Color Management
* Click the All Profiles tab, and then click Add
* Locate and select the new color profile, and then click Add
* Click Close
* Open Control Panel- Hardware and Sound- Display- Change Display Settings (left hand pane)
* Select Advanced settings- Color Management tab- Color Management
* Check the "Use my settings for this device" box
* Click on the Add button
* Scroll down until you find DELL U2410 Color Profile
* Double click it
* Click on Set as Default Profile and close the Color Management screen
* Right click the Desktop
* Click Properties
* Click Settings
* Click Advanced
* Click Color Management
* Click Add
* Locate and select the new color profile, and then click Add
* Click Apply- OK
It's looking good Chris! The Windows Picture Viewer issue appears to be resolved. No issues in Photoshop either.
Will do some more testing, but it's looking good at this point.
Haven't had time to check much, but this profile is very much improved over the first beta ICM.
However I did notice that it creates some visible banding, which can be seen on images like the Lagom gradient test ( http://www.lagom.nl/lcd-test/img/gradient-h.png ) with applications which use the profile, and which is NOT present when the ICM file isn't used. I'm wondering if this new ICM could be fine tuned to remove/minimize the issue more?
Here is an example of what is seen. Please note that you must have colour management disabled to view this since otherwise the ICM profile may introduce banding on both the top and bottom of the image. Also, care should be taken over scaling the image (magnifying etc) since some applications can introduce banding on this type of image.. For example IE8 might make the bottom of this image band, whereas (viewed properly) banding should only be apparent on the top of the image. I suggest using something like Windows Photoviewer or Photoshop to view it. The windows paint program will also suffice, and you can use it to magnify things and make the issue more clear.

This banding isn't only visible in applications like Windows Photoviewer and Firefox, it also appears to be visible in Photoshop too. As said, if possible, it would be nice if this improved ICM could be fine tuned to reduce or even remove this visible banding. But it's almost there, and seems to be a big improvement over the last version so far.
UPDATE - Please see my updated notes below. I get the feeling that this is related to the trade off you do when converting images to an sRGB colour space when using the ICM profile. Hopefully there are still some very minor tweaks which could be done even if this is the case 🙂
Hello - I've been tracking this thread since the beginning - trying to avoid returning this monitor. I'm considering purchasing the Spyder 3 calibration software, and creating a spepcific icm with it. Would that fix the issues we're facing here?
Kinda new at this, so appologize if it's a futile question...
A nice improvement finally making my Photoshop Elements 7 colors to look the same as Windows Photo Viewer but I find that now the colors are a bit undersaturated. The default monitor looked oversaturated and I feel that now you've gone a bit too far in the opposite direction. I have colors set to vivid in my DSLR camera settings yet all my photos now look a tiny bit less saturated in color than what appears to my eyes. With my vivid setting, it should look a little bit more saturated than the colors I see with my eyes. My pictures look like they lack contrast now and don't pop at all anymore. In your next beta version, try to fix this undersaturation problem. Are other people here seeing the same thing?
Yep, looking pretty good from what I'm seeing... but at this point I'm following the lead of P.A.K - and perhaps Dell is too 🙂
How much of this is actually a necessary trade off etc, and how much can be avoided, is what I really don't know. I also don't know how all this relates to the internal hardware LUT, since I'm not sure it's even being used.. The internal hardware LUT on the U2410 can supposedly process things internally as 12-bit colour values. That is to say Red, Green and Blue can have 4096 values, and are internally processed with this greater accuracy before being sent to the panel itself which is a native 8 bit panel - meaning red, green and blue can have 256 values each. (And yes, technically the panel can apparently do 10 bit with dithering applied, but things are already really overly-confusing as it is, huh? 😉 ). But the bottom line is it'd be nice if there's still a way to slightly improve or even remove this banding behaviour..
Other than the jump in black values at the start, and the double values, the other differences under Windows Photoviewer (just to document them) were
At 111 it goes 111,111,111 - 111,110,111 - 112,112,112. (In the middle, between these 2 values, you'd definitely want the green to be 112 or even 111.. how much is down to the ICM I'm not sure)
Continues correctly from 112-172.
At value 172 it goes 172, 172, 172 - 173,173,174 - 174,174,175.
Continues correctly from 175-181.
At value 181 it goes 181,181,181 - 183,182,183 - 184,183,184 - 185,184,185
Continues correctly from 186-237.
At value 237 it goes 237,237,237 - 239,238,239 - 239,239,239 - 241,240,241 - The 239,239,239 value would be better set to 240,239,240. Again, how much is related to the ICM, and how much is the application I'm really not sure.
It then continues correctly from 242 to 255.
Even if the above information can't change much at least it serves as a rough guide for where you're likely to be compromising on image quality when it comes to using the ICM file..
P.A.K. - I've followed most of your posts and while I agree with your observations, I am wondering if a *perfect* ICM is even possible, especially with the two RGB modes. There are likely too many variables. Color management is in its infancy at this point, with Windows 7 (scRGB) not really doing it properly, IE does not, Firefox has its version and OS X is a different scenario as well (its recent gamma point adjustment notwithstanding).
So given that this monitor is capable of a very wide gamut, how does it accurately and without visible distortion, limit that gamut to a smaller color space like RGB? Throw in the way that other third party software interprets color management and you would have a headache indeed, IMO.
I too am hoping that Dell can produce a profile that works perfectly, although I am wondering if it is even possible.
It will be nice when software and OS's catch up on this front. Wide gamut monitors are still far too ahead of their time, IMO.
For a wide gamut, the U2410's two RGB modes are quite impressive. This would be an absolutely perfect monitor for me if the anti-glare was turned down just a tad, but that's a whole other story.
I am wondering if a *perfect* ICM is even possible.
Yep, true, which is why I was sort of pondering that in the comments of the longer posts above. The least we can do is point out the current limitations and see how well they might be minimized (if at all) emoticon.Smile.title
