color cast on your ThinkPad display - fix it with windows 7

i've noticed a good number of users on the ThinkPad board sharing ICC profiles hoping to get better color rendition.   having worked with professional color calibration methods and equipment for over a decade, i can say that shared ICC profiles will give hit-or-miss results due to the nature of calibration and the unique output of each display.

however, all hope isn't lost.   if you have a ThinkPad running Windows 7 and want to remove perceptive color cast (ie: a display looks too cold or warm) then the easiest method is to use the new Windows color calibration tool.   you'll find it in the display control panel or by going to start > run > dccw.exe.

this will give quick and easy control over both gamma and color cast and works with IPS, AFFS, S-PVA, and standard TN panels.   it's also much less expensive than an entry- or mid-level color calibrator.

FYI

 

Thanks for the info.

FWIW, when I ran this a while ago, my LED LCD required no changes. Still, good point to bring up for those who don’t know it’s there.

 

agreed.   not all displays have a color cast.   it can also depend on the individual display and your ambient lighting (tungsten, fluorescent, sunlight, mixed, etc.).

 

Thanks for this post.
I seem to be having trouble with saving/applying my gamma setting though (too high by default). The Color Calibration tool does a great job of fixing it, but every time I restart my computer or switch to/from tablet mode, the color resets.
(Same thing happens with my ClearType settings!)
It's quite frustrating. Any suggestions for a fix?

 

@ Erik,
I'm trying to use the dccw tool to calibrate my RGB LED (same as in Dell Precision M6500) screen but have a question.
When on a pure white background the upper left corner is slightly yellowish. And also, the same background appears more reddish when looking from a 30 degrees or more either side ( horizontal plane). Do you think it can be calibrated or the screen is defective?
Sorry for the OT question.

 

jywc - i had problems with profiles 'sticking' in vista but windows 7 has been ok so far.   i'll check my X200T and see if it loses the profile when switching tablet/notebook modes.

Aikimox - that sounds normal if your display is TN.   because of how TN displays work, a calibrated display will show off-color areas depending on your viewing angle.   every TN display i've ever calibrated has done this, including the W700.   matt kohut touched on this in his blog here.

 

Thanks for the info.

try Calibrize : http://s3.amazonaws.com/calibrize/calibrize_2_setup.exe

found that it's easier to use than Display Color Calibration

 

please post up fhd profiles!

 

like i said above...

i suggest users perform their own calibration.   the point of this thread is not to post each others' profiles.   doing so would defeat the entire purpose.

 

Yes, but unfortunately it doesn't seem to support multiple monitors.

In my case the T510's LCD has a strong blue color cast, correcting it with Calibrize results in a strong yellow color cast on my external monitor.

 

Good info Erik, thanks. Although I find my T410's display to be perfect, right out of the factory.

 

I had the same experience with my T510. I tried Calibrize, and while useful, the results wouldn't compare well to my calibrated Dell 2408 monitor. Neither would results using Windows Color Calibration, plus they was a problem persisting after reboot.

I finally just used the Intel Graphics color enhancement settings to change the gamma values for each of the colors using my calibrated Dell as a reference. I would say I'm about 95% color match to the Dell (a slight problem with greens and yellows). Contrast is obviously not as good. But the blue is tamed.

red gamma = 1.0
green = 0.9
blue = 0.8

My results are good enough to not bother borrowing a calibrator again. Obviously ymmv.

 

Great tip! Thanks!

 

Hi all,


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.



Hope this helps,
