@Davanius it sounds like your unit tracks 2.2 gamma closer than others, including mine, as his ICC profile was designed to correct panels targetting 1.9
I am using the Standard preset. RTS preset appears to add halo's around fonts which I found distracting. I have ran the windows display calibrator and have adjusted the gamma as such that the dots in the middle aren't visible. I have made no other picture changes.
I am happy with how it looks, though i did discover while I had my AOC IPS hooked up too, that it was targetting 2.3-2.4, making things look richer (and darker) than it should.
To be honest, I am not sure if the monitor not tracking 2.2 out of the box is a fault, and if having to correct it with ICC profiles is acceptable, especially when other users are getting panels that are more accurate out of the box, and don't need any software correction.
But from looking at reviews, reddit etc it seems that there are more panels tracking 1.9 than there are 2.2.
