New M6500 Discussion Thread

Neutral greys are very important.

I experimented with selecting different color spaces in control point before disabling it, just to see if it would "keep" the selected mode when it was disabled through msconfig. I'm fairly certain the system does not keep any selected color spaces, but instead what you see is the "native" color space of the display (when control point is prevented from opening).

I'm using the color control application on my XP machine to compare the profile against adobeRGB. I just save the profile to a flash drive and open it up on the XP machine to compare. (It would be nice if Win 7 had the same functionality.)

By the way, even after profiling, the colors on my display are not correct unless I'm viewing images in a color managed application, like Photoshop. (This will be true of just about any wide gamut display on the market, and is not a limitation specific to this particular display.) I've now switched browsers to Safari, which is by default color managed, and does a much better job displaying accurate images on the web (assuming they are correctly tagged with a color space).

 

I have wondered the same thing about the NTSC color space. I know that according to the Dell system engineers that the NTSC setting is supposed to be limited to 45% of the color gamut, but it looks the closest to correct of the 3 control point settings. The Adobe RGB setting is what the engineers say is the widest gamut preset, but the shifted white point makes calibration tougher to achieve. The best color managed workspace solution IMHO is to not load CP at all.

The Dell engineers were adamant in their belief that the panels are coming out of assembly meeting measured specifications. This is what leads me to believe that it is either a software issue with Windows, Control Point, or it is a configuration error in the Epson-Seiko display driver chip that we see as SEC 5443.

Adam - can you load the Control Point connection manager without having to load the Control Point system manager? They are separate programs, but I don't know if they are independent of each other.

 

This is why I use the Profile Loader from Datacolor - to get a color managed Windows environment.

 

Are you also running XP? I could see that as another major variable. What are your Control Point settings?

It does look like your profile is more accurately tracking the AdobeRGB gamut.

 

Your windows environment can only be color managed to the extent that the applications and image files are color managed. Although your profile may improve the way colors are displayed in the windows environment, the colors are not "correct" unless the applications are color managed. (Most windows programs are not color managed, unless they are specifically designed for image editing or DCC.)

I think that many people may be making the mistake of looking at images in a non-color managed application, and thinking that the incorrect colors are caused by the display. They are not. The incorrect colors are caused by the lack of a color managed application/image file. I run two photography websites, and as much as I "preach" to the members, I still see many people uploading images without an embedded color space. These images will not display correctly, no matter how well profiled your monitor is.

 

No, Windows 7-64. Control point is disabled through msconfig.

 

Agreed. I oversimplified. I run Firefox since it is capable of being color profile aware. Most editing that I do is in Lightroom and Photoshop CS4. When I save photos to be viewed online I usually export with sRGB IEC61966-2.1 .

Are running AdobeRGB or ProPhotoRGB for your editing colorspace?

 

Has anyone tried this; How to Change the Color Bit Depth in Windows 7, but in step
4-b make the settings 1920x1200, True Color (32bit), 60Hertz.

And how to Stop Losing Display Calibration with Windows 7.

Just a thought.

 

I'm not Adam, but yes, you can load the Control Point connection manager without having to load the Control Point system manager. I have Control Point system manager disabled through msconfig; however, Dell.UCM.exe is still running on my system, and I can use it to manage wireless and network connections.

 

I use AdobeRGB unless there is a compelling reason to use ProPhotoRGB. (There are reasons for not using ProPhoto as a "normal" working space that require a long discussion to adequately explain.)
