"What you talkin' 'bout Willis?" (a joke probably lost on non-US folks)Hi,
Why would you use it only once ? Screen calibration is a continuous process. It has to be done at least once a month.
The Spyder 2 that I use has an option to be reminded about recalibration that is set by default to be 2 weeks, most write ups I've seen suggest at least once per month for amateur use and in critical professional use I wouldn't be surprised if they calibrate daily.This is the first time I have heard it was not "set it and forget it". How much does it actually drift?
