I use Huey Pro for calibration. I have a notebook and 2 desktop LCDs. This is what I found.
When calibration is done, the desktop LCDs look similar. The notebook looks a bit dull. However calibration didn't note any errors or issues.
On the notebook, the Nvidia panel allows a 'digital vibrance' setting. If I change this, saturation is noticibly changed. If I randomly change this value, rerun the calibration, the saturation is not returned to the old setting.
Thus, I could by comparing identical pics, choose a digital vibrance setting so that the notebook matches the desktop LCDs. Then I run a final calibration and it all looks the same.
But then, how do I know the desktop LCDs are right? Since it doesn't have a digital vibrance, and the calibration doesn't seem to detect a difference?
