Precision M6400 screen color as blue push/tint

I had the same issue with RGB LED screen on my Studio 1737. Apparently, there is nothing wrong with the screen. It's just the way they are - the wide-gamut screens. To fully appreciate it your wide-gamut screen it has to be calibrated with latest version of hardware calibration tool (Spyder3Pro) and you have to be in color managed programm (PhotoShop, LigthRoom) which is set to operate in Adobe RGB color space. Outside those apps you work in sRGB color mode, so the color shift you see is due to difference in color spaces (sRGB vs Adobe RGB, latter being much wider).

I am occasional PhotoShoper, and even though I really liked to work on this screen in PhotoShop and LigthRoom, I couldn't take it for too long for my everyday computing tasks. Eventually I returned the laptop.

I discussed this issue here:

Hope this helps

 

Yeah... I do not believe the issue with the RGB LED screen has anything to do with a blue push or bluish tint... it appears to be another problem altogether. That looks like a much worse problem that a color push.

cruiserandmax... does your E6500 have the LED screen and do you know if it is LG?

 

Try to set the standard sRGB profil to Adobe RGB in Vista. After that reduce the brightness of all colors to 40-43% and gamma to 45% (in the NVidia control panel). The screen just looks too bright, because every subpixel is lit... I did that and on my RGB-LED (E2E) screen it looks like this:





Nevertheless, I get my spyder tool tomorrow and can up a profil for the RGB-LED screen (M6400).

Did you try to switch the Vista standard color profil from sRGB to Adobe RGB?

No, because the WUXGA screen on the E6500 only comes with the RGB-LED or the 2CCFL.

@ cruiserandmax: Did you try do reduce only the brightness of "blue"? I think the screen is much too bright at all. Perhaps you can calibrate your screen with something like a spyder 3 pro tool...

I get my spyder tool tomorrow and can up an profil for the RGB-LED screen (M6400), that might help for someone...

 

Where does one change this?

 

Thanks for the suggestion! I downloaded the Adobe RGB (1998) profile (http://www.adobe.com/digitalimag/adobergb.html) and set it as system default under display settings --> advance settings --> color management --> advance --> device profile, but I don't see a difference. Did I do this correctly?

 

How would you reduce the brightness of only blue... or can this be done on a non LED screen? My screen is the non LED 1440 x 900.

 

Not sure if this is what you are looking for, but under Nvidia Control Panel you get to choose the color channel (all, red, green, blue) and adjust the brightness there.

Desktop context menu --> Nvidia Control Panel --> Advance Settings --> Display --> Adjust desktop color settings

 

My E6500 screen is *NOT* LED.. It's the Ultrasharp WUXGA (CCFL) screen- running Windows XP... I have no idea what could be causing this massive weighting towards blue in the colors displayed on the screen.. I haven't contacted Dell yet.

 

Most very bright notebook screen tend to the blue side... (It's more common on LED backlit screens, because they are brighter and the LED light itself is more blue). On the LED WXGA+ screen I need to reduce blue to 15-20% to get normal colors!

You wrote you calibrated the screen, how did you do that? Eyeballing, or did you use a site like lagom or a monitor calibration tool?

Only adjusting the blue brightness did not do it for me. It did help, but it looks like it is missing something. I adjusted some of the other settings and it looks better, but I am having a hard time getting it to match my desktop monitor, which looks really good.

Can some others share their settings? Maybe I can try some of those and see where it gets me.
