I have the ability to purchase the Asus MG279Q for 425ish shipped... one thing that concerned me was the FreeSync range.. i.e- stopping at 90. What's the point of having a 144mhz monitor when the free sync stops at 90? Is there a way to override that setting and get the full range? Is this a good deal or should I pass on it? Currently looking for used stuff, really don't want to buy new unless I have too.
