When you say 'works perfectly with G-Sync' I'd advise readers to take that recommendation with a HUGE amount of salt.
I've just had to return one of the new Gigabyte 27inch Aorus monitors after reading similar claims about it. In numerous games (Dishonored 2, Wolfenstein 2, Doom) all Id-Tech Rage engine games BTW, the monitor would just go a to a blank screen, with no way of getting back to the desktop, forcing me to do a soft restart from my front case reset button and then it would not boot back into Windows because the monitor would not initialise the screen, which then forced me to do a hard shut down and power up to get back into windows. And on numerous occasions just doing a restart from the Windows desktop would result in the same issue...
So, be VERY careful about buying these so called Freesync (G-Sync compatible) displays.
If you want G-Sync....buy a G-Sync display.
