For the record, I've got this one at last.
It's awesome, all perfect. No flickering with dp1.2, no problems with sleeping/waking up, some minor bleeding in the bottom left corner but really nothing to be worried about. At the contrary I've understood how far from reality are those pixelated pics taken from a cell and compressed in jpeg.
Movies are OUT-FREAKING-STANDING!!!
Games are..... ZOMG what have I've been playing so far, a gameboy?
Windows scaling is ok, not really perfect, menus are good at 150% other things (notifications, system messages, popups....) are too big, but again at 125% menus are too little. Win7 here, hope win10 will fix this.
The only real issue to me is that I was very much used to a dual monitor setup and this is unfortunately not a way to replace it as I first wished. For productivity is ok, 2 progs side by side are awesome, but if you have to switch from one to another continually, as I normally do in my desktop use, than the dual monitor is still way ahead. Also, must be kept at minimun 70-80 cm or you will have your eyeballs roaming around a lot. For games I stay at 110-120 and it's perfect to have all foucsed and available in your FOV.
I'll have to add another 970 to my rig though. One is barely enough to give me 60 fps@ultra settings.
TL;DR: would definitely AOC again
