Probably the best non-hardware calibration information

[reaction]

even with hardware, it doesn't tell you how to set brightness, contrast. I always wonder, since on notebooks the power changes. when you compare 2 LCDs using a colorimeter to calibrate your screen, they still won't match.
it's hard to say what is 'right'

If you mean LCD desktop screens, I have 4 LCDs and I can assure you that if you've used a proper calibration device, there is absolutely no reason why they cannot match - and I assure you mine do. If they didnt I would be in trouble. And that is the entire point in using a calibrated system.

On the issue of notebooks - first of all switch off any power saving options if calibration is important to you. Having said that many notebook screens are not so accurate.
