All – I got a new Windows 10 PC and installed my Spyder3 Pro with the Spyder3Pro_4.0.2_setup software. It error'ed out when I first installed it, so I selected compatibly mode during install and then it installed fine. I ran the calibration on my laptop and it created a new profile. However it seems to be doing the exact opposite of what it should. Before calibration, the colors by default from windows look perfect. Colors completely balanced and accurate. However after running the calibration the new profile it creates is way, waaay off. It creates an inaccurate and very cool white balance and drops down the brightness of the screen significantly. Has anyone had this issue? Of course Datacolor told me to buy the latest version, but I think it would still work with Win 10 like it should? Or if it will not work at all, are there free programs out there I can use that have the same accuracy, or better that the Spyder 3 calibrator did with Windows 7?
