It does overclock to 120 Hz although I haven't verified that frames haven't been dropped. It also increased gamma to some point above 3, which isn't very nice. 96 Hz landed on gamma 2.5. Does anyone know if overclocking the IPS models result in this shift in gamma?
I also noticed that it uses temporal dithering, which is clearly visible on lower refresh rates (like 24 Hz). So the panels are probably 6-bit.
I've made some color profiles, aswell one for 120 Hz. You can try it out and see if it's better with that.
You can find them in the OP post, aswell with profiles from other users.
And a 6 bit PLS panel? No, I don't think anyone would do that kind of crap.
Banding would be terrible on such a panel, though you said something about dithering?
The EDID says it's 8 bit per color, why would the panel use 6 bit then and throw away 2560*1440*4*2 bits per refresh? (I don't know wether there's some kind of compression on that data)
