Windows 7 - Display Color Calibration

I had exactly the same problem. In my case problem was caused by "NVIDIA Display Driver Service", I just unchecked it using "msconfig" and problem solved. This service actually has nothing to do with video card primary functions, just some maintenance junk.

Seems like on my HP d7 the hardware color tuner always ultimately overrides any settings on windows. I spent hours trying to get the windows settings to stick until I finally realized windows was powerless to stop HP from overriding with its own settings every time the computer when to sleep or was restarted.

Here's what I did as a fix for my HP, I'm sure most computers have something similar:

Hey everyone, this was beyond frustrating to me. I'm a photographer and I couldn't edit my photos properly for a long time.

Here's the fix I found:

- Don't use the Windows Calibration. I think HP is just ocnstantly overriding it on the hardwar ke end.
- Go to your desktop, right click, select "Graphics Properties" and go to Color Enhancement. Spend some time tweaking. It's not easy to use. Pull up lots of familiar images to test different settings on. You can use the gray bars in the windows color tuner for reference.

When teh computer sleeps or restarts or whatever, the HP color profile will always be used as the default.

Couldn't find a way to make windwos the default.

Not sure how helpful this is if you use a professional color tuner...

Hope this helps.
