First of all this monitor is awesome and I should've known what to expect but I didnt expect it to be that big, having literally just got it on a black Friday sale and it arriving earlier today. Barely any BLB and pretty much all good out of the box.

Only problem is I cant seem to get the monitor working at 120Hz. I can get it working at 105Hz and 110Hz but as soon as I get to 115Hz or 120Hz the monitor just seems to get into a state of perpetual black, even after using the OSD to overclock and going through to Nvidia Control Panel to change the refresh rate it still does the same thing, sometimes with me accidentally keeping the settings and having to plug another monitor in to sort it out.

I've tried googling for solutions, none so far.
Resetting to factory and trying again, nope.
Updating my Nvidia drivers, nope.

Could it be that I've got a monitor that cant get past 110Hz?
I think another possibility could be my GPU which is a 780 Ti that apparently is DP 1.2, but I would've thought that shouldn't be a problem, someone correct me if I'm wrong. I'm well due an upgrade anyway but I'd rather not since prices are still ridiculous.
