Thank god, my eyes aren’t messed up: It was just a bad calibration device. I tried to match both of my screens yesterday and I couldn’t figure out why the heck a calibration target of D65 has a huge tonal difference on my iMac monitor and on my Eizo CG242W2 – apparently, my eyes didn’t fool me. :P
Today I calibrated both monitors using my old-fashioned Spyder2Pro calibration device. Compared to yesterday’s calibration runs with the X-rite i1 display pro, the colors suddenly matched – on the first try and without tweaking whitepoints or anything. I should have tought of that earlier.
I suspect that the i1 is either damaged or just not able to determine colors correctly. If you encounter erratic calibration results or you have a “feeling” that the result is off the desired target color temperature, make sure to rerun the whole procedure using a different device. It might explain a couple of things.
I’m not sure about that, but I guess for some reason, the i1 – or “EyeOne” – doesn’t “see” as much red as it should. That’s why the color shifted to an ugly blue/green after calibration. I’m not sure wether this is a hardware problem or software related. Maybe the thing just died the classic consumer-electronics-death: Silent, erratic and causing hours of banging your head on the desk and making yourself.
So, just for the record: If you think your calibration results are way off the desired results, double check with another measuring device. It will save you hours of figuring and frustration. For the future: I’ll probably stick to the “Spyder”.. :P
Also, if you’re already trying to calibrate stuff: Give “ColorEyes Display Pro” a try. Nice tool for OSX/Win with a lot of options and producing very nice results. 175$ – but it’s worth it. Never had a good feeling with the bundled programs.
